PROPOSED CHANGE
Appendix C Climatic and Seismic Information for Building Design in
Canada
Footnote: This Appendix is included for explanatory purposes only and does not form part of the requirements.
Introduction
The great diversity of climate in Canada has a considerable effect on the performance of buildings; consequently, building design must
reflect this diversity. This Appendix briefly describes how climatic design values are computed and provides recommended design data
for a number of cities, towns, and lesser populated locations. Through the use of such data, appropriate allowances can be made for
climate variations in different localities of Canada and the National Building Code can be applied nationally.
The climatic design data provided in this Appendix are based on weather observations collected by the Atmospheric Environment
Service, Environment Canada. The climatic design data have been researched and analyzed for the Canadian Commission on Building
and Fire Codes by Environment Canada, and appear at the end of this Appendix in Table C-2., Design Data for Selected Locations in
Canada.
As it is not practical to list values for all municipalities in Canada, recommended climatic design values for locations not listed can be
obtained by contacting the Atmospheric Environment Service, Environment Canada, 4905 Dufferin Street, Downsview, Ontario M3H
5T4, (416) 739-4365. It should be noted, however, that these recommended values may differ from the legal requirements set by
provincial, territorial or municipal building authorities.
The information on seismic hazard in spectral format has been provided by the Geological Survey of Canada of Natural Resources
Canada. Information for municipalities not listed may be obtained through the Natural Resources Canada Web site at
www.EarthquakesCanada.ca, or by writing to the Geological Survey of Canada at 7 Observatory Crescent, Ottawa, Ontario K1A 0Y3,
or at P.O. Box 6000, Sidney, B.C. V8L 4B2.
General
The choice of climatic elements tabulated in this Appendix and the form in which they are expressed have been dictated largely by the
requirements for specific values in several sections of the National Building Code of Canada 2010. These elements include the Ground
Snow Loads, Wind Pressures, Design Temperatures, Heating Degree-Days, One-Day and 15-Minute Rainfalls, the Annual Total
Precipitation values and Seismic Data. The following notes briefly explain the significance of these particular elements in building
design, and indicate which weather observations were used and how they were analyzed to yield the required design values.
In Table C-2., Design Data for Selected Locations in Canada (referred to in this Appendix as the Table), design weather
recommendations and elevations are listed for over 600 locations, which have been chosen based on a variety of reasons. Many
incorporated cities and towns with significant populations are included unless located close to larger cities. For sparsely populated
areas, many smaller towns and villages are listed. Other locations have been added to the list when the demand for climatic design
recommendations at these sites has been significant. The named locations refer to the specific latitude and longitude defined by the
Gazetteer of Canada (Natural Resources Canada), available from Publishing and Depository Services Canada, Public Works and
Government Services Canada, Ottawa, Ontario K1A 0S5. The elevations are given in metres and refer to heights above sea level.
Almost all of the weather observations used in preparing the Table were, of necessity, observed at inhabited locations. To estimate
design values for arbitrary locations, the observed or computed values for the weather stations were mapped and interpolated
appropriately. Where possible, adjustments have been applied for the influence of elevation and known topographical effects. Such

influences include the tendency of cold air to collect in depressions, for precipitation to increase with elevation, and for generally
stronger winds near large bodies of water. Elevations have been added to the Table because of their potential to significantly influence
climatic design values.
Since interpolation from the values in the Table to other locations may not be valid due to local and other effects, Environment Canada
will provide climatic design element recommendations for locations not listed in the Table. Local effects are particularly significant in
mountainous areas, where the values apply only to populated valleys and not to the mountain slopes and high passes, where very
different conditions are known to exist.
Changing and Variable Climates
Climate is not static. At any location, weather and climatic conditions vary from season to season, year to year, and over longer time
periods (climate cycles). This has always been the case. In fact, evidence is mounting that the climates of Canada are changing and will
continue to change significantly into future. When estimating climatic design loads, this variability can be considered using appropriate
statistical analysis, data records spanning sufficient periods, and meteorological judgement. The analysis generally assumes that the
past climate will be representative of the future climate.
Past and ongoing modifications to atmospheric chemistry (from greenhouse gas emissions and land use changes) are expected to alter
most climatic regimes in the future despite the success of the most ambitious greenhouse gas mitigation plans.(10) Some regions could
see an increase in the frequency and intensity of many weather extremes, which will accelerate weathering processes. Consequently,
many buildings will need to be designed, maintained and operated to adequately withstand ever changing climatic loads.
Similar to global trends, the last decade in Canada was noted as the warmest in instrumented record. Canada has warmed, on average, at
almost twice the rate of the global average increase, while the western Arctic is warming at a rate that is unprecedented over the past 400
years.(10) Mounting evidence from Arctic communities indicates that rapid changes to climate in the North have resulted in melting
permafrost and impacts from other climate changes have affected nearly every type of built structure. Furthermore, analyses of
Canadian precipitation data shows that many regions of the country have, on average, also been tending towards wetter conditions.(10)
In the United States, where the density of climate monitoring stations is greater, a number of studies have found an unambiguous
upward trend in the frequency of heavy to extreme precipitation events, with these increases coincident with a general upward trend in
the total amount of precipitation. Climate change model results, based on an ensemble of global climate models worldwide, project that
future climate warming rates will be greatest in higher latitude countries such as Canada.(11)
January Design Temperatures
A building and its heating system should be designed to maintain the inside temperature at some pre-determined level. To achieve this, it
is necessary to know the most severe weather conditions under which the system will be expected to function satisfactorily. Failure to
maintain the inside temperature at the pre-determined level will not usually be serious if the temperature drop is not great and if the
duration is not long. The outside conditions used for design should, therefore, not be the most severe in many years, but should be the
somewhat less severe conditions that are occasionally but not greatly exceeded.
The January design temperatures are based on an analysis of January air temperatures only. Wind and solar radiation also affect the
inside temperature of most buildings and may need to be considered for energy-efficient design.
The January design temperature is defined as the lowest temperature at or below which only a certain small percentage of the hourly
outside air temperatures in January occur. In the past, a total of 158 stations with records from all or part of the period 1951-66 formed
the basis for calculation of the 2.5 and 1% January temperatures. Where necessary, the data were adjusted for consistency. Since most
of the temperatures were observed at airports, design values for the core areas of large cities could be 1 or 2°C milder, although the
values for the outlying areas are probably about the same as for the airports. No adjustments were made for this urban island heat
effect. The design values for the next 20 to 30 years will probably differ from these tabulated values due to year-to-year climate
variability and global climate change resulting from the impact of human activities on atmospheric chemistry.
The design temperatures were reviewed and updated using hourly temperature observations from 480 stations for a 25-year period up
to 2006 with at least 8 years of complete data. These data are consistent with data shown for Canadian locations in the 2009 Handbook
of Fundamentals(12) published by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE). The
most recent 25 years of record were used to provide a balance between accounting for trends in the climate and the sampling variation
owing to year-to-year variation. The 1% and 2.5% values used for the design conditions represent percentiles of the cumulative
frequency distribution of hourly temperatures and correspond to January temperatures that are colder for 8 and 19 hours, respectively,
on average over the long term.
The 2.5% January design temperature is the value ordinarily used in the design of heating systems. In special cases, when the control of
inside temperature is more critical, the 1% value may be used. Other temperature-dependent climatic design parameters may be
considered for future issues of this document.
July Design Temperatures
A building and its cooling and dehumidifying system should be designed to maintain the inside temperature and humidity at certain
pre-determined levels. To achieve this, it is necessary to know the most severe weather conditions under which the system is expected
to function satisfactorily. Failure to maintain the inside temperature and humidity at the pre-determined levels will usually not be
serious if the increases in temperature and humidity are not great and the duration is not long. The outside conditions used for design
Page: 2/43
879
should, therefore, not be the most severe in many years, but should be the somewhat less severe conditions that are occasionally but not
greatly exceeded.
The summer design temperatures in this Appendix are based on an analysis of July air temperatures and humidities. Wind and solar
radiation also affect the inside temperature of most buildings and may, in some cases, be more important than the outside air
temperature. More complete summer and winter design information can be obtained from Environment Canada.
The July design dry-bulb and wet-bulb temperatures were reviewed and updated using hourly temperature observations from 480
stations for a 25-year period up to 2006. These data are consistent with data shown for Canadian locations in the 2009 Handbook of
Fundamentals(12) published by ASHRAE. As with January design temperatures, data from the most recent 25-year period were
analyzed to reflect any recent climatic changes or variations. The 2.5% values used for the dry- and wet-bulb design conditions
represent percentiles of the cumulative frequency distribution of hourly dry- and wet-bulb temperatures and correspond to July
temperatures that are higher for 19 hours on average over the long term.
Heating Degree-Days
The rate of consumption of fuel or energy required to keep the interior of a small building at 21°C when the outside air temperature is
below 18°C is roughly proportional to the difference between 18°C and the outside temperature. Wind speed, solar radiation, the
extent to which the building is exposed to these elements and the internal heat sources also affect the heat required and may have to be
considered for energy-efficient design. For average conditions of wind, radiation, exposure, and internal sources, however, the
proportionality with the temperature difference generally still holds.
Since the fuel required is also proportional to the duration of the cold weather, a convenient method of combining these elements of
temperature and time is to add the differences between 18°C and the mean temperature for every day in the year when the mean
temperature is below 18°C. It is assumed that no heat is required when the mean outside air temperature for the day is 18°C or higher.
Although more sophisticated computer simulations using other forms of weather data have now almost completely replaced degreeday-based calculation methods for estimating annual heating energy consumption, degree-days remain a useful indicator of relative
severity of climate and can form the basis for certain climate-related Code requirements.
The degree-days below 18°C were compiled for 1300 stations for the 25-year period ending in 2006. This analysis period is consistent
with the one used to derive the design temperatures described above and with the approach used by ASHRAE.(12)
A difference of only one Celsius degree in the mean annual temperature will cause a difference of 250 to 350 in the Celsius degreedays. Since differences of 0.5 of a Celsius degree in the mean annual temperature are quite likely to occur between two stations in the
same town, heating degree-days cannot be relied on to an accuracy of less than about 100 degree-days.
Heating degree-day values for the core areas of larger cities can be 200 to 400 degree-days less (warmer) than for the surrounding
fringe areas. The observed degree-days, which are based on daily temperature observations, are often most representative of rural
settings or the fringe areas of cities.
Climatic Data for Energy Consumption Calculations
The climatic elements tabulated in this Appendix represent commonly used design values but do not include detailed climatic profiles,
such as hourly weather data. Where hourly values of weather data are needed for the purpose of simulating the annual energy
consumption of a building, they can be obtained from multiple sources, such as Environment Canada, Natural Resources Canada, the
Regional Conservation Authority and other such public agencies that record this information. Hourly weather data are also available
from public and private agencies that format this information for use with annual energy consumption simulation software; in some
cases, these data have been incorporated into the software.
Snow Loads
The roof of a building should be able to support the greatest weight of snow that is likely to accumulate on it in many years. Some
observations of snow on roofs have been made in Canada, but not enough to form the basis for estimating roof snow loads throughout
the country. Similarly, observations of the weight, or water equivalent, of the snow on the ground have not been available in digital
form in the past. The observations of roof loads and water equivalents are very useful, as noted below, but the measured depth of snow
on the ground is used to provide the basic information for a consistent set of snow loads.
The estimation of the design snow load on a roof from snow depth observations involves the following steps:
1. The depth of snow on the ground, which has an annual probability of exceedance of 1-in-50, is computed.
2. The appropriate unit weight is selected and used to convert snow depth to loads, Ss.
3. The load, Sr, which is due to rain falling on the snow, is computed.
4. Because the accumulation of snow on roofs is often different from that on the ground, adjustments are applied to the ground
snow load to provide a design snow load on a roof.
The annual maximum depth of snow on the ground has been assembled for 1618 stations for which data has been recorded by the
Atmospheric Environment Service (AES). The period of record used varied from station to station, ranging from 7 to 38 years. These
data were analyzed using a Gumbel extreme value distribution fitted using the method of moments(1) as reported by Newark et al.(2)
The resulting values are the snow depths, which have a probability of 1-in-50 of being exceeded in any one year.
Page: 3/43
879
The unit weight of old snow generally ranges from 2 to 5 kN/m3, and it is usually assumed in Canada that 1 kN/m3 is the average for
new snow. Average unit weights of the seasonal snow pack have been derived for different regions across the country(3) and an
appropriate value has been assigned to each weather station. Typically, the values average 2.01 kN/m3 east of the continental divide
(except for 2.94 kN/m3 north of the treeline), and range from 2.55 to 4.21 kN/m3 west of the divide. The product of the 1-in-50 snow
depth and the average unit weight of the seasonal snow pack at a station is converted to the snow load (SL) in units of kilopascals
(kPa).
Except for the mountainous areas of western Canada, the values of the ground snow load at AES stations were normalized assuming a
linear variation of the load above sea level in order to account for the effects of topography. They were then smoothed using an
uncertainty-weighted moving-area average in order to minimize the uncertainty due to snow depth sampling errors and site-specific
variations. Interpolation from analyzed maps of the smooth normalized values yielded a value for each location in the Table, which
could then be converted to the listed code values (Ss) by means of an equation in the form:
where b is the assumed rate of change of SL with elevation at the location and Z is the location’s elevation above mean sea level
(MSL). Although they are listed in the Table of Design Data to the nearest tenth of a kilopascal, values of Ss typically have an
uncertainty of about 20%. Areas of sparse data in northern Canada were an exception to this procedure. In these regions, an analysis
was made of the basic SL values. The effects of topography, variations due to local climates, and smoothing were all subjectively
assessed. The values derived in this fashion were used to modify those derived objectively.
For the mountainous areas of British Columbia, Yukon, and the foothills area of Alberta, a more complex procedure was required to
account for the variation of loads with terrain and elevation. Since the AES observational network often does not have sufficient
coverage to detail this variability in mountainous areas, additional snow course observations were obtained from the provincial and
territorial governments of British Columbia, Yukon, and Alberta. The additional data allowed detailed local analysis of ground snow
loads on a valley-by-valley basis. Similar to other studies, the data indicated that snow loads above a critical or reference level increased
according to either a linear or quadratic relation with elevation. The determination of whether the increase with elevation was linear
or quadratic, the rate of the increase and the critical or reference elevation were found to be specific to the valley and mountain
ranges considered. At valley levels below the critical elevation, the loads generally varied less significantly with elevation. Calculated
valley- and range-specific regression relations were then used to describe the increase of load with elevation and to normalize the AES
snow observations to a critical or reference level. These normalized values were smoothed using a weighted moving-average.
Tabulated values cannot be expected to indicate all the local differences in Ss. For this reason, especially in complex terrain areas,
values should not be interpolated from the Table for unlisted locations. The values of Ss in the Table apply for the elevation and the
latitude and longitude of the location, as defined by the Gazetteer of Canada. Values at other locations can be obtained from
Environment Canada.
The heaviest loads frequently occur when the snow is wetted by rain, thus the rain load, Sr, was estimated to the nearest 0.1 kPa and is
provided in the Table. When values of Sr are added to Ss, this provides a 1-in-50-year estimate of the combined ground snow and rain
load. The values of Sr are based on an analysis of about 2100 weather station values of the 1-in-50-year one-day maximum rain
amount. This return period is appropriate because the rain amounts correspond approximately to the joint frequency of occurrence of
the one-day rain on maximum snow packs. For the purpose of estimating rain on snow, the individual observed one-day rain amounts
were constrained to be less than or equal to the snow pack water equivalent, which was estimated by a snow pack accumulation model
reported by Bruce and Clark.(4)
The results from surveys of snow loads on roofs indicate that average roof loads are generally less than loads on the ground. The
conditions under which the design snow load on the roof may be taken as a percentage of the ground snow load are given in Subsection
4.1.6. of the Code. The Code also permits further decreases in design snow loads for steeply sloping roofs, but requires
substantial increases for roofs where snow accumulation may be more rapid due to such factors as drifting. Recommended adjustments
are given in the User’s Guide – NBC 2010, Structural Commentaries (Part 4 of Division B).
Annual Total Precipitation
Total precipitation is the sum in millimetres of the measured depth of rainwater and the estimated or measured water equivalent of the
snow (typically estimated as 0.1 of the measured depth of snow, since the average density of fresh snow is about 0.1 that of water).
The average annual total precipitation amounts in the Table have been interpolated from an analysis of precipitation observations from
1379 stations for the 30-year period from 1961 to 1990.
Annual Rainfall
The total amount of rain that normally falls in one year is frequently used as a general indication of the wetness of a climate, and is
therefore included in this Appendix. See also Moisture Index below.
Rainfall Intensity
Roof drainage systems are designed to carry off rainwater from the most intense rainfall that is likely to occur. A certain amount of
time is required for the rainwater to flow across and down the roof before it enters the gutter or drainage system. This results in the
Page: 4/43
879
smoothing out of the most rapid changes in rainfall intensity. The drainage system, therefore, need only cope with the flow of rainwater
produced by the average rainfall intensity over a period of a few minutes, which can be called the concentration time.
In Canada, it has been customary to use the 15-minute rainfall that will probably be exceeded on an average of once in 10 years. The
concentration time for small roofs is much less than 15 minutes and hence the design intensity will be exceeded more frequently than
once in 10 years. The safety factors in the National Plumbing Code of Canada 2010 will probably reduce the frequency to a reasonable
value and, in addition, the occasional failure of a roof drainage system will not be particularly serious in most cases.
The rainfall intensity values were updated for the 2010 edition of the Code using observations of annual maximum 15-minute rainfall
amounts from 485 stations with 10 or more years of record, including data up to 2007 for some stations. Ten-year return period
values—the 15-minute rainfall having a probability of 1-in-10 of being exceeded in any year— were calculated by fitting the annual
maximum values to the Gumbel extreme value distribution(1) using the method of moments. The updated values are compiled from the
most recent short-duration rainfall intensity-duration-frequency (IDF) graphs and tables available from Environment Canada.
It is very difficult to estimate the pattern of rainfall intensity in mountainous areas, where precipitation is extremely variable and
rainfall intensity can be much greater than in other types of areas. Many of the observations for these areas were taken at locations in
valley bottoms or in extensive, fairly level areas.
One-Day Rainfall
If for any reason a roof drainage system becomes ineffective, the accumulation of rainwater may be great enough in some cases to cause
a significant increase in the load on the roof. In previous editions of this information, it had been common practice to use the maximum
one-day rainfall ever observed for estimating the additional load. Since the length of record for weather stations in Canada is
quite variable, the maximum one-day rainfall amounts in previous editions often reflected the variable length of record at nearby
stations as much as the climatology. As a result, the maximum values often differed greatly within relatively small areas where little
difference should be expected. The current values have been standardized to represent the one-day rainfall amounts that have 1 chance
in 50 of being exceeded in any one year or the 1-in-50-year return value one-day rainfalls.
The one-day rainfall values were updated using daily rainfall observations from more than 3500 stations with 10 years or more of
record, including data up to 2008 for some stations. The 50-year return period values were calculated by fitting the annual maximum
one-day rainfall observations to the Gumbel extreme value distribution using the method of moments.(1)
Rainfall frequency observations can vary considerably over time and space. This is especially true for mountainous areas, where
elevation effects can be significant. In other areas, small-scale intense storms or local influences can produce significant spatial
variability in the data. As a result, the analysis incorporates some spatial smoothing.
Moisture Index (MI)
Moisture index (MI) values were developed through the work of a consortium that included representatives from industry and
researchers from the Institute for Research in Construction at NRC.10 The MI is an indicator of the moisture load imposed on a
building by the climate and is used in Part 9 to define the minimum levels of protection from precipitation to be provided by cladding
assemblies on exterior walls.
It must be noted, in using MI values to determine the appropriate levels of protection from precipitation, that weather conditions can
vary markedly within a relatively small geographical area. Although the values provided in the Table give a good indication of the
average conditions within a particular region, some caution must be exercised when applying them to a locality that is outside the
region where the weather station is located.
MI is calculated from a wetting index (WI) and a drying index (DI).
Wetting Index (WI)
To define, quantitatively, the rainwater load on a wall, wind speed and wind direction have to be taken into consideration in addition to
rainfall, along with factors that can affect exposure, such as nearby buildings, vegetation and topography. Quantitative determination of
load, including wind speed and wind direction, can be done. However, due to limited weather data, it is not currently possible to
provide this information for most of the locations identified in the Table.
This lack of information, however, has been shown to be non-critical for the purpose of classifying locations in terms of severity of rain
load. The results of the research indicated that simple annual rainfall is as good an indicator as any for describing rainwater load. That is
to say, for Canadian locations, and especially once drying is accounted for, the additional sensitivity provided by hourly directional
rainfall values does not have a significant effect on the order in which locations appear when listed from wet to dry.
Consequently, the wetting index (WI) is based on annual rainfall and is normalized based on 1000 mm.
Drying Index (DI)
Temperature and relative humidity together define the drying capacity of ambient air. Based on simple psychrometrics, values were
derived for the locations listed in the Table using annual average drying capacity normalized based on the drying capacity at Lytton,
B.C. The resultant values are referred to as drying indices (DI).
Determination of Moisture Index (MI)
The relationship between WI and DI to correctly define moisture loading on a wall is not known. The MI values provided in the Table
are based on the root mean square values of WI and 1-DI, with those values equally weighted. This is illustrated in Figure C-1. The
Page: 5/43
879
resultant MI values are sufficiently consistent with industry’s understanding of climate severity with respect to moisture loading as to
allow limits to be identified for the purpose of specifying where additional protection from precipitation is required.

Driving Rain Wind Pressure (DRWP)
The presence of rainwater on the face of a building, with or without wind, must be addressed in the design and construction of the
building envelope so as to minimize the entry of water into the assembly. Wind pressure on the windward faces of a building will
promote the flow of water through any open joints or cracks in the facade.
Driving rain wind pressure (DRWP) is the wind load that is coincident with rain, measured or calculated at a height of 10 m. The
values provided in the Table represent the loads for which there is 1 chance in 5 of being reached or exceeded in any one year, or a
Page: 6/43
879
probability of 20% within any one year. Approximate adjustments for height can be made using the values for Ce given in
Sentence 4.1.7.1.(5) as a multiplier.
Because of inaccuracies in developing the DRWP values related to the averaging of extreme wind pressures, the actual heights of
recording anemometers, and the use of estimated rather than measured rainfall values, the values are considered to be higher than actual
loads(9) Thus the actual probability of reaching or exceeding the DRWP in a particular location is less than 20% per year and these
values can be considered to be conservative.
DRWP can be used to determine the height to which wind will drive rainwater up enclosed vertical conduits. This provides a
conservative estimate of the height needed for fins in window extrusions and end dams on flashings to control water ingress. This
height can be calculated as:
Note that the pressure difference across the building envelope may be augmented by internal pressures induced in the building interior
by the wind. These additional pressures can be estimated using the information provided in the Commentary entitled Wind Load and
Effects of the User’s Guide – NBC 2010, Structural Commentaries (Part 4 of Division B).
Wind Effects
All structures need to be designed to ensure that the main structural system and all secondary components, such as cladding and
appurtenances, will withstand the pressures and suctions caused by the strongest wind likely to blow at that location in many years.
Some flexible structures, such as tall buildings, slender towers and bridges, also need to be designed to minimize excessive windinduced oscillations or vibrations.
At any time, the wind acting upon a structure can be treated as a mean or time-averaged component and as a gust or unsteady
component. For a small structure, which is completely enveloped by wind gusts, it is only the peak gust velocity that needs to be
considered. For a large structure, the wind gusts are not well correlated over its different parts and the effects of individual gusts
become less significant. The User’s Guide – NBC 2010, Structural Commentaries (Part 4 of Division B) evaluates the mean pressure
acting on a structure, provide appropriate adjustments for building height and exposure and for the influence of the surrounding terrain
and topography (including wind speed-up for hills), and then incorporate the effects of wind gusts by means of the gust factor, which
varies according to the type of structure and the size of the area over which the pressure acts.
The wind speeds and corresponding velocity pressures used in the Code are regionally representative or reference values. The reference
wind speeds are nominal one-hour averages of wind speeds representative of the 10 m height in flat open terrain corresponding to
Exposure A or open terrain in the terminology of the User’s Guide – NBC 2010, Structural Commentaries (Part 4 of Division B). The
reference wind speeds and wind velocity pressures are based on long-term wind records observed at a large number of weather stations
across Canada.
Reference wind velocity pressures in previous versions of the Code since 1961 were based mostly on records of hourly averaged wind
speeds (i.e. the number of miles of wind passing an anemometer in an hour) from over 100 stations with 10 to 22 years of observations
ending in the 1950s. The wind pressure values derived from these measurements represented true hourly wind pressures.
The reference wind velocity pressures were reviewed and updated for the 2010 edition of the Code. The primary data set used for the
analysis comprised wind records compiled from about 135 stations with hourly averaged wind speeds and from 465 stations with
aviation (one- or two-minute average) speeds or surface weather (ten-minute average) speeds observed once per hour at the top of the
hour; the periods of record used ranged from 10 to 54 years. In addition, peak wind gust records from 400 stations with periods of
record ranging from 10 to 43 years were used. Peak wind gusts (gust durations of approximately 3 to 7 seconds) were used to
supplement the primary once-per-hour observations in the analysis.
Several steps were involved in updating the reference wind values. Where needed, speeds were adjusted to represent the standard
anemometer height above ground of 10 m. The data from years when the anemometer at a station was installed on the top of a
lighthouse or building were eliminated from the analysis since it is impractical to adjust for the effects of wind flow over the structure.
(Most anemometers were moved to 10 m towers by the 1960s.) Wind speeds of the various observation types—hourly averaged,
aviation, surface weather and peak wind gust—were adjusted to account for different measure durations to represent a one-hour
averaging period and to account for differences in the surface roughness of flat open terrain at observing stations.
The annual maximum wind speed data was fitted to the Gumbel distribution using the method of moments(1) to calculate hourly wind
speeds having the annual probability of occurrence of 1-in-10 and 1-in-50 (10-year and 50-year return periods). The values were
plotted on maps, then analyzed and abstracted for the locations in Table C-2..
The wind velocity pressures, q, were calculated in Pascals using the following equation:
where ρ is an average air density for the windy months of the year and V is wind speed in metres per second. While air density depends
on both air temperature and atmospheric pressure, the density of dry air at 0°C and standard atmospheric pressure of 1.2929 kg/m3 was
Page: 7/43
879
used as an average value for the wind pressure calculations. As explained by Boyd(6), this value is within 10% of the monthly average
air densities for most of Canada in the windy part of the year.
As a result of the updating procedure, the 1-in-50 reference wind velocity pressures remain unchanged for most of the locations listed
in Table C-2.; both increases and decreases were noted for the remaining locations. Many of the decreases resulted from the fact that
anemometers at most of the stations used in the previous analysis were installed on lighthouses, airport hangers and other structures.
Wind speeds on the tops of buildings are often much higher compared to those registered by a standard 10 m tower. Eliminating

Hourly wind speeds that have 1 chance in 10 and 50
Footnote: Wind speeds that have a one-in-”n”-year chance of being exceeded in any year can be computed from the onein-10 and one-in-50 return values in the Table using the following equation:
of being exceeded in any one year were analyzed using the Gumbel extreme value distribution fitted using the method of moments with
correction for sample size. Values of the 1-in-30-year wind speeds for locations in the Table were estimated from a mapping analysis of
wind speeds. The 1-in-10- and 1-in-50-year speeds were then computed from the 1-in-30-year speeds using a map of the dispersion
parameter that occurs in the Gumbel analysis.(1)
Table C-1. has been arranged to give pressures to the nearest one-hundredth of a kPa and their corresponding wind speeds. The value of
“q” in kPa is assumed to be equal to 0.00064645 V2, where V is given in m/s.

Seismic Hazard
The parameters used to represent seismic hazard for specific geographical locations are the 5%-damped horizontal spectral acceleration
values for 0.2, 0.5, 1.0, and 2.0, 5.0 and 10.0 second periods, and the horizontal Peak Ground Acceleration (PGA) value that have and
the horizontal Peak Ground Velocity (PGV), with all values given for a 2% probability of being exceeded in 50 years. The foursix
spectral parameters are deemed sufficient to define spectra closely matching the shape of the Uniform Hazard Spectra (UHS). Hazard
values are 50th percentile (median) values based on a statistical analysis of the earthquakes that have been experienced in Canada and
adjacent regions.(13)(14)(15)(16) The median was chosen over the mean because the mean is affected by the amount of epistemic
uncertainty incorporated into the analysis. It is the view of the Geological Survey of Canada and the members of the Standing
Committee on Earthquake Design that the estimation of the epistemic uncertainty is still too incomplete to adopt into the Code.Hazard
values are mean values based on a statistical analysis of the earthquakes that have been experienced in Canada and adjacent regions.(13)
The seismic hazard values were updated for the 2015 edition of the Code by updating the earthquake catalogue, revising the seismic
source zones, adding fault sources for the Cascadia subduction zone and certain other active faults, revising the Ground Motion
Prediction Equations (GMPEs),(14) and using a probabilistic model to combine all inputs.
The seismic hazard values were updated for the 2010 edition of the Code by replacing the quadratic fit that generated the NBC 2005
values with a newly developed 8-parameter fit to the ground motion relations used for earthquakes in eastern, central and north-eastern
Canada. In 2005, it was recognized that, while the quadratic fit provided a good approximation in the high-hazard zones, it was rather
conservative at short periods, but not at long periods, for the low-hazard zones; however, as the design values are small in the lowhazard zones, the approximation was accepted. The 8-parameter fit gives a good fit across all zones. In general, PGA and short-period
spectral values are reduced, while long-period values are increased. The 2010 values have the following engineering implications:
geotechnical design levels (based on PGA values) are reduced, the design forces for short-period buildings are reduced, and the design
forces for tall buildings are increased. Since zones of low seismicity cover a large part of the country, the seismic information for about

550 of the 650 localities listed in Table C-2. has changed (often in a minor way); only some western localities are unaffected.For most
locations, the new GMPEs are the most significant reason for changes in the hazard results from the NBC 2010. One exception is for
areas of western Canada for which adding the Cascadia subduction source contribution to the model probabilistically causes the most
significant change. In general, in locations in eastern Canada, the seismic hazard at long periods has increased while the seismic hazard
at short periods has decreased—in some places significantly. In locations in western Canada, the seismic hazard at long periods has
increased significantly for areas affected by the Cascadia interface. In other areas, the explicit inclusion of fault sources, such as those in
Haida Gwaii and the Yukon, has also affected the estimated hazard.
Further details regarding the representation of seismic hazard can be found in the Commentary on Design for Seismic Effects in the
User’s Guide – NBC 20102015, Structural Commentaries (Part 4 of Division B).

Note to Table [A-2] C-2.:
(1)
Refer to the Commentary on Design for Seismic Effects in the Structural Commentaries on the National Building Code of
Canada 2010 for more detailed data on seismic parameters in selected metropolitan areas.
RATIONALE
Problem
The introductory paragraph and seismic hazard values in Table C-2 of NBC 2010 do not reflect current knowledge of seismic
hazard across the country.
Justification - Explanation
A major effort on the part of SCED has resulted in much improved estimates of seismic hazard across the country. This is the first
major update of the seismic hazard model in Canada in 20 years, and will bring the NBC in line with modern seismic hazard maps
used in building codes in the United States and other jurisdictions.
For most locales, the new GMPEs are the most significant reason for changes in the hazard results from 2010. The values have
also changed as a result of inclusion of Cascadia subduction source probabilistically to seismic hazard for areas of western
Canada and the explicit inclusion of fault sources such as those in Haida Gwaii and the Yukon.
In some localities in western Canada, affected by the Cascadia subduction zone, it has been determined that the current code
values are not conservative, and may not achieve the desired level of earthquake safety for some types of structures. The proposed
code changes will rectify these issues.
Cost implications
In some location the assessed hazard has gone up and in other areas it has gone down. In areas where the assessed hazard has
gone up, the cost implications are unavoidable as they are required for seismic safety. There may be cost increase or decrease of
the order of 1% of the overall cost of the building wherever the estimated hazard has changed.
Enforcement implications
None
Who is affected
Building officials, Consultants, Contractors and Building Owners

NECB11 Div.A 1.4.1.2.(1)
NECB Definitions
Adding NBC defined term storage garage to NECB
PROPOSED CHANGE
[1.4.1.2.] 1.4.1.2. Defined Terms
[1] 1)
The words and terms in italics in this Code shall have the following meanings:
Storage garage* means a building or part thereof intended for the storage or parking of motor vehicles
and containing no provision for the repair or servicing of such vehicles. (See Appendix A.)
A-1.4.1.2.(1)
Defined Terms.
Building Envelope Application
Several types of spaces can be unconditioned and thus need to be treated differently, e.g., mechanical rooms, crawl
spaces, garages, loading docks.
There is also a need to consider components that separate spaces that are conditioned to substantially different
temperatures (e.g., swimming pools, skating rinks).
Gross Lighted Area
Gross lighted area cannot be tied to the building envelope because the building envelope relates only to conditioned
space. Gross lighted area is used in the calculation of interior lighting power allowance, which includes all interior
lighting, whether the space is conditioned or not, and some lighting of exterior spaces; lighting in elevator and service
shafts, if provided at all, is not factored in since it would not have a significant impact on the interior lighting power
allowance.
Interior Lighting
Building envelope
Given the definition of building envelope, Clause (a) of the definition of interior lighting applies to lighting of all
conditioned spaces.
Other sheltered spaces
Storage garages (parking garages), bus shelters and retail outlets (such as market stalls) are examples of interior spaces
that are sheltered from the exterior environment and not necessarily conditioned where the interior lighting is intended
only to illuminate that space.
The illumination of a covered exterior walkway may be considered exterior lighting or interior lighting, depending on
whether the lighting is intended to light the area around the walkway or only the walkway itself. If only the covered
walkway is illuminated, limits for lighting interior corridors would apply.
Overall Thermal Transmittance (U-value)
The overall thermal transmittance, U-value in W/(m2·K), is the inverse of the effective RSI in m2·K/W. To convert RSI
to an imperial R-value, use 1 m2·K/W = 5.678263 h·ft2·°F/Btu.
Service Room
Typical examples of service rooms include boiler rooms, furnace rooms, incinerator rooms, garbage-handling rooms, and
rooms to accommodate air-conditioning or heating appliances, pumps, compressors and electrical equipment. Rooms such
as elevator machine rooms and common laundry rooms are not considered to be service rooms.
Storage Garage
Committee: Executive Committee (43.5.3)
Page: 1/2
841
Entrances at which vehicles stop for a short time beneath an unenclosed canopy to pick up and drop off passengers are
not considered as storage garages.
Suite
Tenancy in the context of the term “suite” applies to both rental and ownership tenure. In a condominium arrangement, for
example, dwelling units are considered separate suites even though they are individually owned. In order to be of
complementary use, a series of rooms that constitute a suite must be in reasonably close proximity to each other and have
access to each other either directly by means of a common doorway or indirectly by a corridor, vestibule or other similar
arrangement.
The term “suite” does not apply to rooms such as service rooms, common laundry rooms and common recreational rooms
that are not leased or under a separate tenure in the context of the Code. Similarly, the term “suite” is not normally applied
in the context of buildings such as schools and hospitals, since the entire building is under a single tenure. However, a
room that is individually rented is considered a suite. A warehousing unit in a mini-warehouse is a suite. A rented room
in a nursing home could be considered as a suite if the room were under a separate tenure. A hospital bedroom, on the
other hand, is not considered to be under a separate tenure, since the patient has little control of that space, even though he
or she pays the hospital a per diem rate for the privilege of using the hospital facilities, which include the sleeping areas.
RATIONALE
Problem
The NECB uses the terms "parking garage" and "storage garage" while the NBC uses only the defined term "storage
garage". The use of the terms should be consistent since they mean the same thing.
Introduce the NBC defined term "storage garage" into the NECB, without change. All occurrences of parking garage
in the NECB will be changed to storage garage (editorial).
Cost implications
None.
None.
Who is affected
Designers, manufacturers, builders, specification writers and building officials.

Problem
The existing trade-off path is limited in that it only includes one daylighting system (interior blinds) and is based on one location (for
effect of available daylight hours).
Add the CSA C873 (BEEM) methodology for lighting as an additional option for demonstrating compliance with
the trade-off path. The BEEM is more flexible and more accurate as it includes three daylighting systems (standard
systems, light-directing systems and permanent shading systems) and three latitude ranges (30° to 45°, 45° to 60°,
60° to 75°). Due to the fact that the daylighting considerations for the existing trade-off path calculations are based
on the analysis for the location Ottawa, the BEEM results are considered to be more suitable for locations that are
much further North or South from Ottawa.
To better align with the existing trade-off path, some modifications were made in the application of BEEM under the
new trade-off path.
While the absolute results of the BEEM calculation for estimating the energy use of a lighting system will not be
identical to that of the existing trade-off path calculations, the two methods give similar relative results for
compliance demonstration purposes when the proposed building’s lighting system energy use is compared against
that of the reference building's. Thus, as long as the overall conclusion is the same, the methods are comparable.
Based on calculations and validation, there is strong indication that the two methods are comparable.

Problem
The trade-off path must align with the prescriptive path requirements.
To account for the energy impact of new control types and their application in the prescriptive path, changes were
required in the trade-off path. New occupancy-sensing mechanisms and factors were introduced in Table 4.3.2.10.B.
A new adjustment factor was added to Table 4.3.2.8. for combined primary and secondary daylighted areas. The
factors to Account for Occupancy-Sensing Mechanism in 4.3.2.10.B are based on available case study and research
data and account for the variability based on space types, occupancy types, and building types. The committee used
expert knowledge, experience and judgment when specific data was not available for a particular application.

temperature is less than the outdoor air temperature or the return air enthalpy is less than the outdoor air
enthalpy. (See Appendix A.)
3)
Except as provided in Sentence (6), systems described in Sentence (1) shall be designed to mix outdoor
air and return air to a temperature as near as possible to that required to condition the space, even when
mechanical cooling is provided.
4)
Systems described in Sentence (1) with cooling capacities of 70 kW or more shall incorporate cooling
equipment that can operate at less than full capacity, with the lowest stage providing no more than 25%
of the full capacity of each system.
5)
Systems described in Sentence (1) with cooling capacities of more than 25 kW but less than 70 kW
shall incorporate cooling equipment that can operate at less than full capacity, with the lowest stage

Problem
The dew point temperature equation in the appendix lacks clarity. Therefore it is unclear how to determine
whether a high-limit shutoff of 24°C or 18°C should be set for fixed dry bulb controls or air economizers. The
NECB does not state which locations are in “dry” and “humid” climates.
The proposed change addresses a code change request on clarity of the appendix note and provides improved
guidance on high limit shut-off (HLSO) control set points for air economizers.
The range of outside air temperatures to be used for HLSO set points of air economizers with fixed dry bulb control
has been updated to reflect ASHRAE 90.1 thermal criteria. Also, the equation provides guidance to users on the
efficient set point range for canadian climates.

prescriptive requirement.
EXISTING PROVISION
5.2.3. Fan System Design
5.2.3.1. Application
1)
Except for equipment covered by Article 5.2.12.1. and whose minimum performance includes fan
energy, this Subsection applies to all fan systems
a) that are used for comfort heating, ventilating or air-conditioning, or any combination thereof,
and
b) for which the total of all fan motor nameplate ratings is 10 kW or more (see A-5.2.3.1.(2) in
Appendix A).
2)
For the purposes of this Subsection, the power demand of a fan system shall be the sum of the demand
of all fans required to operate at design conditions to supply air to the conditioned space. (See
Appendix A.)
5.2.3.2. Constant-Volume Fan Systems
1)
Where fans produce a constant airflow rate whenever the system is operating, the power demand
required by the motors for the combined supply and return fan system at design conditions shall not
exceed 1.6 W per L/s of supply air delivered to the conditioned space, calculated using the following
equation:
where
W = power demand, in watts,
F = design flow rate, in L/s,
SP = design static pressure across the fan, in Pa, and
η = combined fan-drive-motor efficiency, expressed as a decimal fraction.
(See Appendix A.)
5.2.3.3. Variable-Air-Volume Fan Systems
1)
For fan systems through which airflow varies automatically as a function of load, the power demand
required by the motors for the combined supply and return fan system, as calculated using the equation
Page: 1/4
830
in Sentence 5.2.3.2.(1), shall not exceed 2.65 W per L/s of supply air delivered to the conditioned space
at design conditions. (See Appendix A.)

In variable-air-volume systems, any individual supply, relief or return fan with a power demand greater
than 7.5 kW and less than 25 kW, as calculated using the equation in Sentence 5.2.3.2.(1), shall
incorporate controls and devices such that, if air delivery volume is reduced to 50% of design air
volume, the corresponding fan power demand will be no more than 55% of design wattage, based on
the manufacturer‘s test data.
3)
In variable-air-volume systems, any individual supply, relief or return fan with a power demand equal
to or greater than 25 kW, as calculated using the equation in Sentence 5.2.3.2.(1), shall incorporate
controls and devices necessary to prevent the fan motor from demanding more than 30% of design
wattage at 50% of design air volume, based on the manufacturer’s test data.
A-5.2.3.1.(2)
Fan System Design.
Although the allowed maximum power demand of a fan system is based solely on the supply airflow, the calculation of
actual power demand includes supply fans, return fans, relief fans, and fans for series fan-powered boxes, but not
parallel-powered boxes or exhaust fans such as bathroom or laboratory exhausts.
A-5.2.3.2.(1)
Constant-Volume Fan Systems.
This type of system includes bypass variable-air-volume systems in which the airflow through the fan is not varied.
Both supply and return fans must be accounted for, but not exhaust fans.
The power demand of the motors refers to the power drawn by the motors and not their nameplate rating.
A-5.2.3.3.(1)
Variable-Air-Volume Fan Systems.
The power demand of supply, relief and return fans—but not that of exhaust fans—must be accounted for in
Sentence 5.2.3.2.(1).
The power demand of fans for series-fan-powered boxes—but not that of fans in parallel-fan-powered boxes—must be
accounted for in Sentence 5.2.3.2.(1).
The power demand of the motors refers to the power drawn by the motors and not their nameplate rating.
8.4.4.16. Outdoor Air
1)
Except as provided in Sentence (2), the outdoor air ventilation rates for the reference building shall be
modeled as being identical to those determined for the proposed building in Sentence 8.4.3.7.(1).
2)
Except for heated parking garages, demand control ventilation strategies shall not be modeled in the
reference building.

Enclosed semi-heated spaces or conditioned spaces where fuel-powered vehicles or mobile fuelpowered equipment or appliances are intermittently used shall be provided with sensors and demand
control ventilation systems capable of limiting the expected air contaminants to acceptable levels by
[a] --) staging the ventilation fans, or
Page: 2/4

[b] --) modulating the outdoor airflow rates.
(See Appendix A.)
A-5.2.3.4.(1)
Demand Control Ventilation Systems.
Examples of enclosed spaces targeted by Sentence 5.2.3.4.(1) are indoor sports arenas where fuel-powered equipment is
used for maintenance of the play area (such as an ice-surfacing vehicle in an ice-rink arena), warehouses with propanefueled forklifts, and heated indoor parking garages. In such spaces, contaminant levels are often controlled through onand-off staging of a dedicated fan system. However, some ventilation systems use variable-speed fans to modulate
between a set minimum (which can be as low as 0 when the contaminant levels are low enough) and the peak
airflow rates needed to control the levels of contaminant in the air. Air contaminants generally controlled by such
systems are carbon monoxide (CO) and nitrous oxides (NOx), depending on the type of fuel used.
Spaces where fuel-powered vehicles or mobile fuel-powered equipment or appliances are used on a semi-continuous basis
(e.g. multiple forklifts actively used in a distribution warehouse) may be exempted from complying with Sentence
5.2.3.4.(1), subject to the approval of the authority having jurisdiction. However, some standards, such as ASHRAE
62.1, “Ventilation for Acceptable Indoor Air Quality,” still require a minimum ventilation rate based on occupancy or
other activities carried out in the space. It is expected that a means will be provided to evacuate exhaust air from fixed
fuel-powered appliances and equipment directly to the outdoors. Thus, only spaces where vehicles or mobile equipment or
appliances with combustion engines are used are targeted by this requirement.
[8.4.4.16.] 8.4.4.16. Outdoor Air
[1] 1)
Except as provided in Sentence (2), the outdoor air ventilation rates for the reference building shall be
modeled as being identical to those determined for the proposed building in Sentence 8.4.3.7.(1).
[2] 2)
Except for heated parking garagesas required by Article 5.2.3.4., demand control ventilation strategies
applied in the proposed building shall not be modeled in the reference building.
RATIONALE
Problem
Ventilation of parking garages can consume significant energy without appropriate controls. The NECB article
8.4.4.16 set reference modeling requirements of parking garage ventilation to current practice but there was no
requirement in the prescriptive path of Part 5 (HVAC).
The practice of using sensors to stage fan systems (on/off) in spaces where combustion-using equipments and
vehicles are present is well established. For indoor parking garages specifically, this practice is an acceptable
solution recognized by NBC.
The proposed prescription imposes this current practice on all semi-heated and conditioned spaces where transient
and/or variable use of combustion equipment and vehicles is present.
Also ASHRAE Standard 90.1-2010 has a similar prescription; while being limited to indoor parking garage, it
covers both heated and unheated parking garage.
Cost implications
Minimal; the expected fan and heating (and possibly cooling) energy savings are deemed to generate a payback on
the initial installation cost of the control system of less than 3 year.
None, could be enforced using the existing infrastructure.

RATIONALE
Problem
To update the maximum water discharge rate of hot service water supply fittings and shower heads with current
practice requirements.
Supply Fittings Faucets (Private):
ASME/CSA, Manitoba, CalGreen, ASHRAE, IAPMO, ICC and WaterSense are using 5.7 Lpm. Most
manufacturers are transitioning their product line to 5.7 Lpm. The product is presently easily available and the
purchase cost is not significantly different. The installation cost remains unchanged. There are no performance
issues or regulatory constraints with this product.
Supply Fittings (Public):
ASME/CSA, ASHRAE, IAPMO, ICC and CalGREEN (1.5 Lpm) set the maximum at 1.9 Lpm. All non-residential
lavatory faucets in the USA have been required by the ASME national standard to operate with a maximum flow
rate of 1.9 Lpm for approximately 15 years. The product is easily available and the purchase cost is not
significantlydifferent. The installation cost remains unchanged. There are no performance issues or regulatory
constraints with this product.
Page: 2/3
829
Shower Heads:
ASME/CSA provide for 9.5 Lpm and 7.6 for high efficiency. Manitoba specifies 6.6 Lpm but this may be too low
and lead to some risk regarding thermal shock or scalding. Ontario is also moving towards 7.6 Lpm. CalGreen,
ASHRAE, IAPMO, ICC and WaterSense are using 5.7 Lpm or 7.6 Lpm. The product is presently easily available
and the purchase cost is not significantly different. The installation cost remains unchanged. There are no regulatory
constraints with this product.
Cost implications
Most manufacturers are transitioning their product lines to make available water-use efficient products. The
proposed limits therefore reflect the current market direction. The products are presently easily available and the
purchase costs are not significantly different. The installation costs remain unchanged.
Due to the lower flow rate of public lavatory supply fittings, design consideration should be given as to the necessity
of installing a hot water recirculation system, or other design solution, to reduce wait time for hot water. Should this
be the case, the cost of the system as well as the cost of installation would be increased. There would not be any
regulatory constraints as a result however.
The proposed limits will not have an effect on the existing enforcement/regulatory framework and the products are
presently being used in many jurisdictions.
Who is affected
Code user, enforcement agencies, manufacturers, consumers.

[6.2.8.2.] --- Pressure Control
[1] --)
Pressure booster systems shall be provided with at least one pressure sensor that starts and stops the

Except for safety devices, pressure-reducing devices shall not be installed on a pressure booster
system.
A-6.2.8.1.
Sizing of Hydro-Pneumatic Storage Tanks.
In order to prevent short-cycling of the pump in a pressure booster system during periods of low- to no-flow demand,
pressure booster systems must be provided with a hydro-pneumatic storage tank capable of meeting a theoretical low
service water demand during a minimum amount of time. Otherwise, the pressure booster system would have to run
almost continuously in almost no-flow conditions to meet the smallest demand, such as the occasional flushing of a toilet
in a residential high-rise building.
There are several industry-recognized ways to determine the volume of water that needs to be stored in the tank. They are
typically based on the number of start-stop cycles per hour and the nominal capacity of the pressure booster system, or on
the peak system demand rate multiplied by a number of minutes representing the length of time the system is not
operating. These sizing methodologies tend to result in large tank sizes, which are more appropriate for constant-speed
pressure booster systems where the principal objective is to avoid short-cycling in mid- to high-flow demand situations.
The application of Sentence 6.2.8.1.(1) will typically result in the pressure booster system going through about 15 startstop cycles per hour, which corresponds to a typical industry recommendation to avoid shortening the service life of the
system’s pump. It will also prevent constant-speed pressure booster systems from operating in low- or no-flow conditions
for a significant amount of time, while avoiding short-cycling in mid- to high-demand periods.
Variable-speed pressure booster systems require a significantly smaller tank than constant-speed ones.
A-6.2.8.2.(1) Sensors for Pressure Booster Systems.
Pressure sensors for variable- speed pressure booster systems should be located near critical fixtures, which determine the
required system pressure.
[8.4.4.21.] 8.4.4.21. Service Water Heating Systems

[c] c) energy type.
[2] 2)
Where the energy type of the proposed building's service water heating system is an air-, water- or
ground-source heat pump, the energy type of the reference building's service water heating system shall

[8] 8) Where the proposed building's service water heating system comprises multiple water heaters, the
reference building’s service water heating system shall be modeled with the same number of water
heaters.
[9] 9)
Where the proposed building's service water heating system is a recirculation system, the circulation
pumps shall be modeled as
[a] a) constant speed operation, and
[b] b) having a flow rate that is identical to that of the proposed building's circulation pumps.
RATIONALE
Problem
Part 6 currently focuses only on service water heating systems and their demand.
However, many buildings are equipped with pressure booster systems since the pressure in the aqueduct is often
insufficient to provide enough lift for mid- and high-rise buildings. Pressure booster systems can consume a
significant amount of energy per year and better practice designs can result in significant savings.
Since its 2010 edition, ASHRAE 90.1 has requirements pertaining to pressure booster system (see ASHRAE
90.1-2010 or -2013, art. 10.4.2). Standard 90.1-2010 is to enforced in all states by the end of 2013. Adding these
requirements to NECB helps harmonize with the United States. Those three requirements form the basis of the
requirements proposed for NECB under 6.2.8.
ITT Bell & Gossett describes in its bulletin TEH-1096A a procedure for sizing hydro-pneumatic storage tank to
prevent short-cycling at low- to no-flow conditions. Figure 5.4 proposes amounts of water that should be stored in a
hydro-pneumatic tank according to the occupancy of the building and the pressure booster system capacity to meet
demand in low-flow conditions for a period of about 30 minutes.
Converting those values to low-flow demand (i.e. average gpm), 6.2.8.1. (1) would result in a pressure booster
system that would take about 1 minute to fill an empty tank and would be stopped between 25 minutes (hospital)
and 200 minutes (apartment building) in typical low-flow condition. 6.2.8.1 (1) results in higher storage capacity
than recommended by bulleting THE-1096A since those recommendations may generate short-cycling situations in
mid- to high-flow demand situations.
Sentence 6.2.8.1. (2) assumes that low-flow demand corresponds to about 10% of system design flow and that
variable pressure booster system would tend to operate at the minimum speed required to slowly raise system
pressure (i.e. meeting slightly more that the demand). This implies that the booster system could operate for a
significant amount of time (at rather low speed) before stopping, preventing short-cycling, and would eventually be
stopped between 3 minutes (hospital) and 20 minutes (apartment building).

Cost implications
Small to none, since ASHRAE 90.1-2010/2013 requirements in the United States will means that there will be a
large availability of pressure booster systems meeting these requirements.
ASHRAE 90.1-2010/2013 10.4.2 c) is somewhat vague; proposed NECB 6.2.8.1.(1) and .(2) are clearer
requirements and easier to show compliance with. Other requirements can easily be show to be compliant with
drawings and specifications.

EXISTING PROVISION
8.4.2.7. Internal and Service Water Heating Loads
1)
The energy model calculations shall account for the loads due to
a) number of occupants,
b) receptacle equipment,
c) service water heating systems, and
d) miscellaneous equipment, as applicable.
(See Appendix A.)
2)
The energy model shall calculate the sensible and latent loads due to internal loads, lighting, and appliances. (See
A-8.4.3.2.(1) and A-8.4.3.3.(1) in Appendix A.)
3)
The internal loads shall be adjusted for each time interval referred to in Sentence 8.4.2.2.(4) based on the applicable
operating schedule in A-8.4.3.2.(1) in Appendix A.
4)
5)
A-8.4.2.7.(1)
The calculation of sensible loads due to lighting shall account for
a) the effect of the proportion of radiant and convective heat, and
b) the percentage of heat gain from lighting going directly to return air.
Miscellaneous equipment located within a conditioned space that affects the energy consumption of one or more of the
building systems described in Sentence 8.4.2.2.(1) shall be included in the energy model and its energy consumption shall
be calculated.
Internal and Service Water Heating Loads.
Common internal loads include loads due to lighting, presence of occupants, equipment that is directly operated by the occupants such as
personal computers, equipment that operates automatically such as computer servers, and other non-energy-consuming loads such as food to
be frozen in a freezer. Internal loads usually generate sensible, latent and/or radiant heat gains.
Except for lighting, internal loads are not regulated within the scope of the NECB. However, because they add cooling and/or heating loads
to the building’s HVAC and service water heating systems, internal loads representative of the building type or space function should be
included in the compliance calculations in order to correctly evaluate part-load performance of the HVAC and service water heating systems
and, by extension, the energy consumption of the proposed and reference buildings. The internal loads must be modeled identically in the
proposed and reference building energy models; only the energy consumed by the equipment and systems regulated by the NECB can be
modeled differently in the proposed and reference buildings.
Appendix Note A-8.4.3.3.(1) provides default internal loads and associated hourly profiles for occupants and receptacle equipment that are
representative of different building types and space functions. While any internal load values are permitted to be used, those default values
should be used in the absence of better information.
The default values for receptacle equipment generally represent common electrical equipment directly operated by the occupants, as well as
some automatically operated electrical equipment commonly found in the building types listed. For example, for an office building, the
default value implicitly includes equipment such as office computer servers, photocopiers, printers, escalators, elevators, etc., but does not
include the servers of main data centres.
Reasonable professional judgment should be applied in evaluating whether less common internal loads are correctly represented or not in the
default values and profiles for receptacle equipment. These less common loads are generally associated with commercial and industrial
operations and processes, such as
• manufacturing machinery in an industrial building
• medical imaging equipment in a hospital
• computer servers in a data centre of an office building
Page: 1/18
839
• swimming pool water heating in a recreation centre
• cooking appliances and refrigeration equipment in a commercial kitchen or restaurant
Generally, if the default values provided in Appendix Note A-8.4.3.3.(1) appear too small compared to the actual expected internal loads,
some commercial and/or industrial operations and/or processes will not be correctly represented.
8.4.3.3. Internal and Service Water Heating Loads

A-8.4.3.3.(1)
Internal and service water heating loads used in the energy compliance calculations shall be representative of the proposed
building's type or space functions. (See Appendix A.)

[b] --) a window height of 1.8 m, and
[c] --) a width that would result in a window-to-wall-ratio meeting the maximum FDWR value permitted by Article 3.2.1.4.
[6] --) The primary and secondary sidelighted areas shall be determined assuming a depth of 2 m. (See Appendix A.)
[7] --) For the purpose of determining the daylighted area under skylights, the calculations shall be performed assuming a single square
skylight positioned at the centre of each thermal block
[a] --) that is sized to meet the maximum skylight-to-roof ratio permitted by Article 3.2.1.4., and
[b] --) whose projection onto the floor extends horizontally in all directions for a distance equal to 0.5 times the ceiling height.
(See Appendix A.)
[8] --) The combined input power within the daylighted areas shall be the sum of the daylighted areas multiplied by the appropriate
interior lighting power allowance specified in Table 4.2.1.6.
[9] --) Where photocontrols are required by Subsection 4.2.2., their effect shall be evaluated in accordance with Sentences (10)
to (12).
[10] --) Calculations of daylighting levels in each thermal block shall be performed assuming
[a] --) the thermal block is a single open space surrounded by opaque walls,
[b] --) floor, wall and ceiling reflectances of 0.15, 0.50 and 0.80, respectively,
[c] --) illuminance levels measured at a height of 0.75 m from the floor, at the edge of the daylighted areas that is farthest
from the source of daylight and measured perpendicular to this source, and
[d] --) a fenestration visible light transmittance corresponding
[i] --) to the area-weighted average of the visible light transmittance for that thermal block in the proposed building, or
[ii] --) if there is no fenestration in the proposed building’s corresponding thermal block, to a value of 0.50.
[11] --) The illumination set-point of the photocontrols shall
[a] --) be identical to that of the proposed building’s photocontrols, or
[b] --) if there are no photocontrols in the proposed building, be representative of the space use assuming no task
lighting.
(See Appendix A.)
[12] --) Where the energy model is unable to perform detailed daylighting calculations, the interior lighting power allowance
in the daylighted area shall be multiplied by the factor for daylight harvesting, FDL,i, as calculated in accordance with
Article 4.3.3.7.
A-8.4.4.6.(3)
Controls Based on Space Occupancy.
Subsection 4.2.2.-2015 presents several prescriptive control requirements for various space types. In establishing the reference building’s
energy consumption, the controls resulting in the highest energy consumption can be selected where compliance options are provided.
A-8.4.4.6.(6)
Depth of Sidelighted Areas.
The depth of sidelighted areas is affected by window head height and obstructions within the space. Obstructions cannot be established for
the reference building, therefore, the 2 m default depth stipulated in Sentence 8.4.4.6.(6) is to account for hypothetical obstructions, such as the
walls of closed offices, high partitions, etc., that could be present within a single thermal block.
A-8.4.4.6.(7)
Daylighted Area under Skylights.
For the purpose of energy model calculations for the reference building, it is assumed that the toplighting contributions are from skylights
only and not rooftop monitors.
A-8.4.4.6.(11)
Illumination Set-points.
See Table A-8.4.3.3.(1)B.-2015 for default illuminance levels.
RATIONALE
Problem
During the fall 2013 public review, new prescriptive requirements for occupancy-sensing and daylighting controls were proposed for
Section 4.2 of the NECB. For consistency, Part 8 needs to be updated to reflect those changes.
Page: 15/18
839
This proposed change updates Part 8 for the impact on energy usage from occupancy-sensing and daylighting controls to reflect the
changes to the Part 4 prescriptive requirements presented during the 2013 public review. The change will help ensure a consistent
performance level whether the prescriptive or performance approach is used. Further details on the Part 4 prescriptive changes can be
found by viewing PCF 585 at http://www.nationalcodes.nrc.gc.ca/eng/public_review/2013/pcfs/necb11_divb_04.02.02._000585.php
For Part 8, the modeling approach presented applies a similar approach to the Part 4 trade-off path. Further details on the Part 4 tradeoff path and proposed approach can be found with PCF 840 which is also currently out for PR.
The reference building is modelled with the controls of the prescriptive path controls. Fenestration area criteria are provided for sideand top-light areas. Lux values provided in Table A-8.4.3.3.(1) are based on ASHRAE 90.1 2013 general lux values for the room.
However, in some spaces, task lighting dominates and a weighted average of general and task is presented. Further, whole building
avearage lux values are presented. Lux values were rounded to the nearest 25 value.
The proposed building is modeled with the controls of the design. Credit provided for daylighting and personals controls is calculated
with the same factors for occupancy sensing as the Part 4 trade-off path. The factors are applied to the lighting power density (LPD),
which is then modeled on an hourly basis. Use of a multiplier factor to the Part 4 trade-off F factors to account for the hourly
calculation method of Part 8 was investigated. However the conservative estimates of savings were not found to justify the addition of
a multiplier.

8.4.4.9. Equipment Oversizing
The proposed change is intended to clarify wording that could be open to

EXISTING PROVISION
8.4.4.9. Equipment Oversizing
1)
The heating equipment of the reference building shall be modeled as being oversized by the lesser of
a) the percentage of oversizing applied to the proposed building, or

A-8.4.4.9.
Equipment Oversizing.
Oversizing is an accepted industry practice that is implemented when safety factors are applied on the calculated load,
when the reserve capacity for future use is included, or when equipment precisely matching the building’s calculated
load is not available on the market. However, gross oversizing can lead to the inefficient operation of equipment: for
example, poor efficiency when equipment is operating at part-load. The 30% oversizing for heating equipment, which
includes pick-up loads, and the 10% oversizing for cooling equipment stated in Article 8.4.4.9. are upper limits selected
to avoid gross oversizing when modeling the reference building.
RATIONALE
Problem
Currently, the code wording could lend itself to interpretation issues on the reason oversizing modeling requirements
are included in Part 8.

The proposed change adds an appendix note to provide greater clarity. For modelers a description of why oversizing
can occur is provided. The note also clarifies that the upper limit the values in clauses 8.4.4.9.(1).(b) and

RATIONALE
Problem
A new prescriptive requirement in Subsection 5.2.13 for heat rejection equipment was proposed during the fall 2013
public review. For consistency Part 8 needs to be updated to reflect the prescriptive requirement.
With the proposed change updates the energy usage of the reference cooling towers systems will
match the new Subsection 5.2.13 prescriptive requirements. Making the change helps ensure a consistent
performance level whether the prescriptive or performance approach is used.
Specification of constant speed operation is now included in the prescriptive requirement and no longer needs to be
specified in Part 8. Similarly, fan power requirements no longer need to be specified since the prescriptive
path has performance requirements based on equipment type. The proposed prescriptive requirements were
presented in PCF 597 and can be found at

RATIONALE
Problem
Some of the greatest issues pertaining to the construction of new storage facilities involve the issues of fire safety
requirements and atypical interpretations to the local codes. Except for Ontario, Manitoba and Alberta, many
locations have no building code specific to self-storages, and local planners attempt to apply the ‘most applicable’
code to the project.
The time required to review and apply various codes to a project can greatly lengthen a project approval time.
Recent projects in BC have taken 12 months for the permit process which was largely caused by the circulation and
interpretation of requirements pertaining to the building plans. This could have been avoided had self-storage
specific code requirements been clear. In contrast the last two projects completed in Ontario took an average of 6
months for approvals to be attained. The projects in each case were similar in size, design and features.
Today there are just over 3,300 facilities operating in Canada, providing over 65 million sq. ft. of rentable space.
Each year the industry adds approximately 10 to 20 new facilities and more than 1,000,000 sq. ft. of rentable space
into the Canadian marketplace.
Page: 4/10
906
This proposed change, which forms part of the self-service storage garage package, defines the maximum quantities
of flammable and combustible liquids permitted to be stored in the buildings and prohibits dispensing, handling, and
transfer of flammable or combustible liquids in the rental space, and other common areas.
Maximum Quantities
The maximum quantities were determined based on the maximum quantities permitted in attached garages and sheds
for assembly and residential occupancies (Article 4.2.4.6.). Since each individual storage unit typically serves a
household, it was felt that each storage unit would have no need to store flammable or combustible liquids in excess
of this quantity. By limiting the quantity of flammable and combustible liquids permitted to be stored in each unit, it
was felt that the risk of ignition resulting in explosion or fire was maintained at the same level compared to what is
currently acceptable in attached garages or sheds.
Dispensing and Handling
Permitting dispensing and handling of flammable and combustible liquids within the individual storage units and
other common areas was felt to be an unacceptable level of risk.
Cost implications
These changes will have a negligible or positive cost implication since the applicable requirements pertaining to
self-service storage buildings will be harmonized and clarified throughout the Code.
The proposed changes can be regulated using available resources. No additional implications to enforcement.

RATIONALE
Problem
As of August 23, 2012 – Underwriters Laboratories of Canada has withdrawn the Technical Supplements ULCS601 (A)-2001, ULC-S603 (A)-2001, ULC-S615 (A)-2001, ULC-S630 (A)-2001. By withdrawing these
certification programs, Code users have no means to repair or refurbish a storage tank without sending the tank back
to the manufacturer or replacing it with a new storage tank. In some cases where the tank is difficult or costly to
remove, on-site refurbishment is required.
As the referenced CAN/ULC publications and Certification programs are no longer available, replacement of these
references in the NFC was required. For aboveground storage tanks, API 653, "Tank Inspection, Repair, Alteration,
and Reconstruction" and STI SP031, “Standard for the Repair of Shop Fabricated Aboveground Tanks for Storage
of Combustible Liquids on Field Erected Storage Tanks” were considered. For underground storage tanks,
CAN/ULC-S669, “Standard for Internal Retrofit Systems for Flammable and Combustible Liquid Tanks” can be
used when upgrading or retrofitting the lining of the tank. The scope of CAN/ULC-S669 applies when replacing the
tank lining, and does include procedures when repairing the host tank. It is not the intent of this reference to apply
the repair of the host tank without also changing the tank liner.
The intent is that these references for the repair of aboveground and underground storage tanks provide authorities
having jurisdictions and manufacturers with a set of requirements for the on-site repair of a storage tank.
Cost implications
On a case by case basis this may have a negative or positive effect. Providing a means for tank owners to repair a
storage tank on-site may be more cost effective than either replacing the storage tank with a new tank, or sending the
tank back to the manufacturer for repair and re-installation. In a small number of cases, the withdrawn certification
program may have required fewer repair requirements to comply with and in these cases, the proposed repair costs
may be more expensive (especially for underground storage tanks). In some jurisdictions, repair of underground
storage tanks is not permitted and this would have no cost impact on those tanks.
This change would have a positive impact on enforcement by providing a means for the on-site repair of storage
tanks. Authorities having jurisdiction will be able to verify that the tank has been repaired to a recognized tank
standard by the certification label.
Page: 2/3

This change would provide up to date clarity for authorities having jurisdiction and can be enforced with current
infrastructure and therefore facilitate enforcement. No increase in resources anticipated to be required.
Who is affected
regulators, engineers, building owners, tank owners, designers, fire services, and building managers.

Problem
Generally, it is understood that the storage of compressed gases is permitted within a fire compartment in
accordance with Part 3 of Division B of the NFC. If quantities are below the value found in Table 3.2.7.1. and
Sentence 3.2.8.2.(2) limits of Div. B of the NFC, then cylinders of compressed gases would be permitted to be
stored in a laboratory, otherwise they would be required to be located in a storage room. NFC limits lighter-than-air
flammable gases in a building, stored outside of a storage room, to 60 m3 in unsprinklered buidling of combustible
construction and 170 m3 in a sprinklered building of noncombustible construction.
Currently, cylinders of compressed gases connected to equipment are not considered to count towards the volume in
storage since these are classified as "in use". The quantity of compressed gases considered to be "in use" is therefore,
not regulated.
The Task Group on Use and Classification of Dangerous Goods:Laboratories (TG) has concluded that the maximum
quantities of dangerous goods in a laboratory (fire compartment) either "in use" or stored, present the same hazard to
people and the building in a fire emergency and/or upon accidental release of the gases in the atmosphere. When
cylinders of compressed gases are exposed to flame, the hazard associated with the expansion of the gas(es) inside
each cylinder is indepented whehter the cylinders are "in use" or in storage.
The TG confirmed the intent to limit the maximum quantity of dangerous goods classified as compressed gases in a
laboratory, including those cylinders "in use".
The Task Group on Use and Classification of Dangerous Goods:Laboratories (TG) considered that the hazards
associated with the presence of cylinders of compressed gases in laboratories used for experiment, measurement,
etc., were equivalent to the hazards associated with the storage of these cylinders.
In is understood that some quantities of dangerous goods are required to ensure the normal operation of the various
experiments being conducted in laboratories. However, the TG concluded that the large majority of cylinders of
compressed gases found in laboratories poses a serious threat to the safety of person and to the building. In several
areas, those quantities were in excess of the normal necessary operation. The TG confirmed that the use, handling
and storage of dangerous goods, including flammable and combustible liquids, in laboratories need to comply with
the current provisions of Parts 3, 4 and 5 of Div. B of the NFC.
This meant that the maximum quantities defined in Table 3.2.7.1. of Div. B of the NFC should also apply to the
quantities of dangerous goods used in laboratories, including the ones considered to be "in use".
To establish the limits defined by the proposed changes, the TG considered the limits defined in the NFPA 45,
"Standard of Fire Protection for Laboratories Using Chemicals." This proposal restricts the maximum quantities
permitted for flammable and oxidizing gases not in cabinet and toxic gases in a cabinet, based on suggestions to
keep toxic gases in cabinets at all times. The proposal further restricts these quantities in buildings containing
educational, assembly or Group B major occupancies. This measure is generally consistent with NFPA 45 standard
limits for low hazard laboratories.
Cost implications
The TG considered that some costs would be required to accomodate the lesser quantities of dangerous goods found
in laboratories with the provision of additional storage cabinets. However, it is believed that those extra costs would
be compensated with a better management of the quantities of cylinders of compressed gases and better storage
practices in dedicated storage room.

stadia, bleachers and arenas,
b) a concentrated load of 1.0 kN applied at any point for access ways to equipment platforms,
contiguous stairs and similar areas where the gathering of many people is improbable, and
c) 0.75 kN/m or a concentrated load of 1.0 kN applied at any point, whichever governs for
locations other than those described in Clauses (a) and (b).
2)
Individual elements within the guard, including solid panels and pickets, shall be designed for a load of
0.5 kN applied over an area of 100 mm by 100 mm located at any point in the element or elements so as
to produce the most critical effect.
3) The loads required in Sentence (2) need not be considered to act simultaneously with the loads
provided for in Sentences (1) and (4).
4) The minimum specified load applied vertically at the top of every required guard shall be 1.5 kN/m
and need not be considered to act simultaneously with the horizontal load provided for in Sentence (1).
