WITH TRADE ISSUE
What a summer we had and now, in the middle of winter, keeping warm
has once again come onto the agenda. Keeping cool in summer is one
thing but winter presents its own challenges. Many of our homes are not
insulated resulting in lower internal temperatures. This isn’t good for one’s
health, or one’s overall living environment. That is why in this – our first
anniversary Trade Issue – we’ve focused on a number of matters related
to insulation and keeping the perfect ambient temperature. We cover the
options for insulating existing buildings and for ensuring new buildings
comply with code clause H1; thermal efficiency.
• Comprehend and apply knowledge of the regulatory
environment of the building construction industry
• Organise and manage building projects
• Establish design briefs and scope of work and prepare
preliminary design
• Apply technical knowledge of construction methods and practice
• Demonstrate knowledge of current building and trade practice
Once you have read this edition
of Trade Issue remember to
keep a record of your learning.
1 hour of learning = 1 point
We also look at the different forms of insulation that are available and
describe how you can establish compliance with H1 for new buildings.
While this is an issue for new structures, it isn’t the case with existing
buildings. Nevertheless, it is important to remember that a building

consent is required where un-insulated exterior walls are to be insulated.
Many people are not aware of this requirement or the impact of
unconsented work on insurance. As you’ll see, there are plenty of options
when insulating buildings.
Earthquake matters are still making headlines and Trade Issue is no
exception. While seismic activity in the Canterbury region appears to be
reducing, the broader effects are not. Government has just completed its
consultation on the upgrading requirements for all non-residential,
multi-unit and multi-storey residential buildings. You will also have seen
or heard the adverts explaining the changes to household insurance.
We also announce our new Adaptable Building Solutions range, the ideal
solution for farm buildings, workshops or factories. If the words
‘flexibility’ and ‘functionality’ strike a chord, this system will work
wonders for you.
See the new range on display at the Mystery Creek Fieldays at Hamilton.
Bunnings sites at G105 and G107 will showcase the Adaptable Building
Solution along with the latest from AEG, Ryobi and much, much more.

It warrants
buying the best
AEG is a symbol of quality and performance. Combine this
with a warranty extension developed just for the trade and
the proposition is simply the best.
Since 1887, German brand AEG has been a
power house of innovation and development.
When you’re buying AEG you’re buying the
best. That alone justifies having AEG on the
job with you but to make matters even better
AEG Powertools has announced it will
dramatically increase the length of its trade
warranty. Now the company is offering customers
a total of 6 years on their power tools and 3 years
on their batteries and chargers. Without question
this is the best trade warranty on the market.
and chargers. The extended warranty will give
you additional peace of mind and confidence that
you’re covered should anything untoward happen.
Bunnings is proud to have AEG as part of our
product portfolio and even more so now that
they are offering such a sound guarantee of
product support.
We’ve got you covered
Taking advantage of this offer involves a simple
‘two-step’ process. After purchase you will be invited
to create a user account on the AEG Powertools
website. Once there it is simply a matter of
registering the power tools/batteries/chargers
by scanning in a purchase receipt.
The warranty extension gives you the option to
extend your warranty from the standard 3 years
available on power tools and 1 year on batteries
The beauty of having the receipt on file electronically
removes the need to file it – and find it – at a later
date. The risk of receipt fading is also eliminated.
Technology innovators
AEG has invested heavily in upgrading technology
in their 18V Cordless range. This includes the
introduction of brushless motors, fix tec tool free
interchangeable blades, higher-amperage batteries
and a broader range of skins including the new
Omni Pro interchangeable head Multi-Tool.
There’s a lot of innovative new product in the
pipeline. It’s going to be a very exciting year for
AEG Powertools in New Zealand and, by definition,
for people who want quality and performance in
what they bring to the job.
The AEG Powertools extended warranty is
offered in addition to all other rights and
remedies provided under the New Zealand
Consumer Guarantee Act 1993.

Adaptable buildings
– now there's a solution!
In human terms, the ability to adapt is crucial for success
and survival. Commercial buildings – from farm structures to
factories – are no exception. “Buildings can be added to
over time to create extra
spaces for living, working
or storing.”
The introduction of the Adaptable Building Solutions range continues
Bunnings’ commitment to deliver innovation and new product lines.
Available nationwide, this new range of portal style buildings offers flexibility
and functionality rolled into one. Utilising Laminated Veneer Lumber (LVL)
framing, it allows the structure to be built with a completely clear span.
Meaning there are no inconvenient structural pillars inside the footprint
of the building.
Des Bickerton, Bunnings’ Commercial Manager, says the range is easily
scalable, enabling customers to add on additional sections. “They’re the
perfect solution for stabling or workshops through to large factories. The
clear span construction is also ideal for aircraft or automotive application.”
As with all structural Buildings it requires a permit and if to be used as
a Dwelling will need to meet the requirements necessary to comply with
the building code.
Starting at 12m wide x 18m long the standard range building can extend
to 15m wide and as long as 30m. Heights range from 3.6m to 4.8m. This,
says Des Bickerton, allows additional space within the building by adding
a mezzanine floor for use as offices, living and accommodation or as
additional storage space.
Longrun zincalum Custom Orb Endura wall cladding is standard with
zincalum Trimlin/Plumdek Endura for the roof. Coloursteel and H3.2
utility ply is optional. Two roller doors are also standard and range in
size from 3.6m height x 4.8m wide for the 3.6m high building through
to 4.8m high x 4.8m wide for the 4.8m high option.
Though the LVL solution has a wide range of applications it complements,
says Des Bickerton, the Farm Building Offer Bunnings launched in
October 2011.

“Flexibility and functionality
make the Adaptable
Building Solutions range
a real winner.”
“Value and adaptability provide real benefits to our farming clients. Delivering
this in a larger building portal format is also going to find favour. We’ve found
that our range of kitset and custom designed buildings have found a real niche
down on the farm. Being able to work with existing suppliers and channels has
meant Bunnings have been able to deliver an exceptional value farm building
range throughout the country.”

BUILDING
by Rodney Dickens
National upturn may have stalled prematurely
Interest rates are the most powerful driver of upturns and downturns in residential
building and it can take up to 12 months for changes in mortgage interest rates to
impact on the national number of consents for new dwellings. Given the timing of
the fall in mortgage interest rates last year, the national number of consents for new
dwellings should have a bit more upside over the next few months. But the upturn
may have stalled prematurely.
The numbers of dwelling and section sales reported by REINZ generally provide
advance warning of what is likely to happen to the number of consents for new
dwellings over the subsequent 5-6 months. Both dwelling and section sales
should have increased more over the last few months as a lagged response
to the fall in mortgage interest rates last year. But as the chart shows, dwelling
sales have increased a bit more but section sales have largely drifted sideways.
Upside to interest rates delayed
The high NZ dollar is largely why the Reserve Bank has signaled it won’t start hiking
the OCR until the second half of 2014 despite near double digit house price inflation,
although an earlier start to hikes can’t be ruled out. This implies mortgage interest
rates may be reasonably stable for another year, allowing the improvement in net
external migration to drive a bit more upside in consents for new dwellings.
However, the high cost of sections and new housing remains a constraint.
Unaffordable new housing, especially for first home buyers, continues to keep the
level of residential building below historical average levels. This is why Housing
Minister Nick Smith’s campaign to get down new housing costs is so important,
although I am a bit dubious of how much progress he will make given the different
approach favoured by the likes of the Auckland City Council.
Insurance bottlenecks hampering rebuilding
Statistics NZ reported only 57 quake-related consents for new dwellings for March,
which is little different from the numbers for January and February. This implies the
rebuilding in Canterbury has stalled. Insurance bottlenecks and to a lesser extent the
slow processing of consents by the council continue to delay rebuilding.
However, the total number of consents for new dwellings in Canterbury has
continued to rise in recent months. This has probably been aided by insurance
companies paying a moderate proportion of people with quake-damaged properties
in cash. Some of these people are likely to be building on new sections, with these
consents not included in the official quake-related numbers.

Managing the fallout
from building failure
An ambitious work programme is being
proposed to lessen the risk of building
collapse and subsequent loss of life.
performance a building needs to meet 1/3rd of New Zealand Building Code
B1 (structure) performance requirement. This is often referred to as 33% NBS.
It will, however, cost money to achieve this level of structural upgrade.
Inevitably a tradeoff between cost and performance needs to be considered.
To that end Government has proposed that:
• Building owners obtain a seismic capacity
assessment of their building within 5 years.
One of the positive outcomes following the Christchurch earthquakes was
the convening of a Royal Commission tasked with making some sense of
the causes that led to the tragic loss of life.
• The results of these assessments will
be recorded on a Council held
public register, and
As part of its response to the recommendations that have been produced
by this inquiry, the Government has proposed an ambitious work programme
in relation to handling all earthquake prone non-residential buildings or
multi-unit and multi-storey residential buildings.
• All necessary structural upgrade work
is completed within 15 years.
Some flexibility in keeping buildings strong
In terms of definitions, the Building Act says that an earthquake prone
building is one that, in a moderate earthquake, would be likely to collapse
causing death or injury or damage to another property. This definition also
includes barns, warehouses and bridges but does not apply to residential
buildings unless the building comprises two or more levels and contains
three or more household units.
Within this proposal, there is some flexibility. For instance some buildings,
such as farm buildings, might be exempt from these upgrade requirements.
In turn other buildings, such as those located on critical transport routes, might
need to be upgraded more quickly. It is the Government’s expectation, however,
that by the end of the 15 year period all non-exempt earthquake prone buildings
would have been strengthened or demolished.
Conservative estimates calculate that there are between 15,000 and 25,000
buildings that would be considered earthquake prone. In an ideal world all
these buildings would be able to withstand a moderate earthquake without
sustaining major damage. It has been estimated that to achieve this level of
The consultation period has now closed and the Government’s consideration of
the submissions will be revealed in due course. In the meantime it’s important to
remember that owners of earthquake prone buildings are already subject to the
local Councils earthquake-prone building.
11
Nationally this has created some level of inconsistency. When the 2004 Building
Act came into force, each Council was required to develop and implement its
own policy as to how it would identify, record and, where necessary, manage
earthquake prone buildings. Government was concerned that there has been no
nationally consistent policy around buildings with a structural performance that
is less than 33% NBS and it is anticipated that this work will address this issue.
Those areas where earthquakes are considered more likely, such as Wellington,
have policies that adopt a more active approach to identifying earthquake prone
buildings. In these areas, councils have undertaken a desktop, qualitative initial
evaluation. The focus of this evaluation was to compare the current performance
with the NBS and where it was less than 34% it was recorded as earthquake prone.
As a result many building owners in the larger metropolitan areas will already be
aware of the status of their building. This might not be the case in smaller,
provincial towns.
Once a building is identified as earthquake prone then the local council is able to
set a timeframe for the necessary upgrade.
While the local earthquake prone policy may exert demands on the building owner,
applications for a building consent (especially if it involves a change of use) could
trigger a structural upgrade.
“There are some discrepancies
in policy making as some
parts of New Zealand are
more earthquake prone
than others.”
But will the benefits always outweigh the costs?
Trade Issue is committed to helping you
reduce the burden of compliance plus draw
your attention to key determinations that can
help the way you do business.
By way of definition, determinations are binding decisions made by Ministry
of Business, Innovation and Employment (MBIE) that have arisen as a result
of a dispute, usually between a council and a customer. While each decision
is site specific the discussion is always applicable to other building situations.
They can provide alternative methods for you to manage your compliance and
your interaction with your local council.
The one under the spotlight is a Schedule 1(k) exemption. Using this exemption
can make good business sense. Many of you will already know about Schedule 1;
that is work for which a building consent is not required. Schedule 1(k) is a clause
in this schedule that allows an individual council to exempt work not covered as a
right in this schedule.
It is a good compliance management tool but to
date has been underused and poorly understood.
An individual council can issue
a schedule 1(k) exemption where
it considers that:
(i) The building work will
almost certainly be undertaken
in accordance with the building
code, this is called a schedule 1(k)(i)
exemption or
Some argue that structurally upgrading a building will deliver a number of benefits
including a reduction in risk to people and other property. Other benefits could
include improved tenancy rates on the basis that prospective tenants will select
non-earthquake prone over earthquake prone buildings. In turn banks will be
more likely to lend on strengthened buildings, therefore these buildings have
a market premium.
(ii) Where failure to comply with the building
code would be unlikely to endanger people
or damage other buildings, this is called a
schedule 1(k) (ii) exemption.
However, the actual cost of the upgrade may not deliver an adequate return
on this investment. Furthermore, and paralleling the leaky building experience,
the scarcity of the skills to carry out this work will translate to escalating costs.
Where building work is minor and low risk in nature and where the
benefits of requiring a building consent do not exceed associated
compliance costs.
And what about our heritage buildings?
The loss of so many of Christchurch’s older buildings is a reminder that
despite being a new country we do have a heritage that we need to protect.
To that end heritage buildings, in particular, need to be upgraded in a way
that maintains their historic integrity. New Zealand has about 7,160 listed heritage
buildings covered by the earthquake prone building requirements. These include
wharves, flagpoles, wharenui and bridges. In many cases these buildings are not
in private ownership and so collectively we face the cost of the upgrade and the
risk of not upgrading it.
Whatever the outcome of Government’s deliberations, there are no easy answers
and clearly there will be dissenting views. The time allowed for structural upgrades
to take place will ultimately determine the number of buildings that are strengthened
and the number that are demolished.

Welcome to
Compliance Corner
Or as outlined by MBIE
Obviously obtaining a schedule 1(k) exemption will provide business benefit
since it means that a building consent is not required. The positives are in cost
and time savings since you won’t be waiting for inspections.
The case of the farm outbuilding
In February of this year a determination was issued that related to an application
made to the Waipa District Council for a schedule 1(k) exemption. The owner
wished to construct a farm implement shed on his property. The person in question
is a structural engineer and the building was to be situated 200m from the nearest
boundary and 150m from the nearest dwelling. On that basis the owner considered
that consent was unnecessary since it was unlikely to endanger any person or
property in the event of failure.
However, the Waipa District Council did not accept that it should be covered
under schedule 1(k)(ii). Their view was that the proposed work was not minor
or low risk in nature.
Furthermore they refused to issue a schedule 1(k)(i) exemption because they did
not consider that the application provided sufficient detail for it to assess that the
resulting building work was likely to comply with the code.
In order to make this decision they required documentation that was as detailed
as if a building consent application was to be made.
The determination concluded that:
1. The council gets to choose what type of exemption is the right one. That is
whether the building work is most likely to meet the building code, and so
the building consent process will not add any value or that if the building work
does not meet the code it will not have an effect on anyone or any
other property.
2. The type of information that you would need to provide when making
a schedule 1(k) application is more than provided by the owner in this
instance, but is less than the information required when applying for a
building consent.
3. The information required is summarised as:
Schedule 1(k)(i) exemption
• Evidence of competence
and prior experience
• Complexity of proposed work
relative to competence
• Independent QA programme
Schedule 1(k)(ii) exemption
• Location of proposed work
• Use of building work
• Proximity to other buildings
• Level of risk to life and property

the following flowchart.

What projects might be candidates for exemption?
Examples that would be suitable for a schedule 1(k)(i) exemption,
that is compliance with the building code is almost assured include:
• Bridges and other large engineering projects
• Buildings overseen by independent engineer or other skilled
and experienced professional
• Repetitive building work where independent quality assurance
demonstrate that it is highly unlikely that the work will not comply
with the building code, for instance large marquees, bouncy castles
Examples suitable for a schedule 1(k)(ii) exemption include:
• Farm or out buildings
• Signage
As you would expect there are fewer projects suitable for the schedule 1(k)(ii)
exemption. Where compliance with the building code is unimportant, in general
it won’t be covered by the Building Act at all.

• Resources consent

Out with the old
and in with the new
The hot topic of
temperature control
New building code clauses mean that old fire
management practices have gone up in smoke.
With winter here creating a warmer, dryer and
overall healthier environment is once again a
burning issue.
On April 1st last year, a new set of Fire Building Code clauses – also known as C
docs – were released. Included with these was a new set of acceptable solutions for
handling a range of situations stemming from fire. These changes were highlighted
in the November 2012 Trade Issue article Where There’s Smoke Also Expect Fire.
In order to ease the transition from having to adopt the new clauses, a period of
grace meant that compliance with the fire related code clauses could be achieved
using either set of documents and either set of acceptable solutions.
That period ended on April 1st 2013 meaning that old clauses have now been
superseded by the new.

From there effective heating and cooling – in order to retain the ambient temperature
– can only be achieved if your building is well insulated and has reduced airflow.
Again, there are many ways of achieving this but in simple terms it is about
maintaining air tightness by blocking off all air leakage points.
Acceptable solution C1/AS2
Functional and
performance objectives
Acceptable solution C1/AS1
Clause C2

Acceptable solution C1/AS1
Functional and

To achieve this is sometimes a tall order. International studies, for example, talk
of an optimum ambient internal room temperature of 20 – 22°C. When you consider
Met Service figures that say that the national average maximum temperature ranges
from a summer high between 20-30°C to a winter low between 10-15°C, getting the
balance just right is often easier said than done.
The reality is the only way to maintain a comfortable temperature in all climates –
and without adopting expensive passive house technology options – is by using
heating and cooling devices. Be they heat pumps, air conditioning or simply
opening a window.
Comparing the old with the new
Clause C1
Outbreak of fire
One of the joys of being ‘civilised’ is the ability to control ambient temperatures
thereby creating the sort of ideal environment we want where we work or live.
This now means that for new building work, compliance must be demonstrated
using the 2012 fire code clauses. Only the new set of acceptable solutions may be
considered as relevant and suitable documentation.
In essence the changes were made to reinforce the objective of the New Zealand
Building Code clause C (protection from fire) designed to:
• Safeguard people from an unacceptable risk of injury or illness caused by fire
• Protect other property from damage caused by fire
• Facilitate fire fighting and rescue operations
Again, to make sure you’re totally up with the play either re-read the November
article or visit www.mbie.govt.nz.
Insulation is one of the elementary ways to battle the elements. It reduces
unwanted heat loss or gain and can decrease the energy demands of heating
and cooling systems
To achieve this, the entire building envelope, ideally, should be insulated,
• Ceiling / roof (roof cavity if skillion roof)
• External walls
• Joinery (Glazed windows and doors)
• Floors (whether concrete floor slab or suspended timber floors)
But how you insulate a building depends on whether it is a new building
or an addition or alteration to an existing building.
For new buildings the relevant code clause is H1 (thermal efficiency)
and the required performance is defined as follows:
H1.3.1 The building envelope enclosing spaces where the temperature
or humidity (or both) are modified must be constructed to
(a) provide adequate thermal resistance; and
(b) limit uncontrollable airflow.
In turn, there are two NZ Standards that relate to residential buildings –
• NZS 4214: 2006
Methods of determining the total thermal resistance of parts of buildings
• NZS 4218: 2004
Energy efficiency-housing and small building envelope
You can use any method you want to achieve compliance, but your method
needs to be accepted by the local Building Consent Authority. They need to
be satisfied on reasonable grounds that what you propose will meet the
performance requirements of H1.
Consider this
The main factors that the designer needs to consider when planning on temperature
management techniques and options are:
1. The relevant climate zone – New Zealand is divided into three climate zones
(See map to your right)
2. The total window area in relation to the total wall area
3. The window area orientation east and southwest
14
4. Skylight area
Retrofitting existing buildings
5. Non CA-Rated down lights
The situation for existing buildings is a little different. Retrofitting insulation in
an existing building is not about achieving compliance with H1 but it is about
improving the quality of the internal environment. The reality is that achieving
compliance for an existing building would involve expensive renovation work
including the installation of double-glazing.
6. Construction materials
7. Construction methods (design)
Methods for achieving compliance
There are three accepted methods for establishing compliance.
Methods Description

NZS 4218 is the acceptable solution for
NZBC clause H1

because they have compensated with a
higher R-value elsewhere in the building.

However it is worth the effort as owners say the difference experienced by
insulating external walls is huge.
Then there is the question of which products to use. There is a huge selection
of products to choose from and your ultimate choice will depend on a number
of factors including:
• Cost
• Level of sustainability
• Personal preference
Zone 1
Zone 2
Zone 3
Ministry of Business, Innovation and Employment has advice on what to
consider when installing insulation in external walls: www.dbh.govt.nz/retrofitting
-insulation-guidance. This guidance defines the relevant performance clauses and
outlines factors that need to be considered. These factors include the building, the
level of maintenance as well as the environment. If you have any doubts or
questions it would pay to talk to your local Building Consent Authority (BCA).
• Method of installation
The methods you choose will be dependent on the building, the products
and preference.
Zones 1 and 2
But where insulation is retrofitted the requirements of s112 apply (refer to Trade
Issue June 2012). Installing insulation in the ceiling and under floor does not
require a building consent, but if insulation is being installed in external walls
then a building consent is required. The reason for this is that installing insulation
fundamentally changes the moisture management performance of the wall.
Remember that when applying for a new building consent you would normally
nominate the preferred insulation product because at the building consent stage
the type and R-value of insulation must be notated on the plans and appended
to the specifications. This information provides the BCA the grounds upon which
to establish compliance with H1.
If you want ‘hot off the Press’ information about how to keep your cool
when making insulation decisions talk to your Bunnings Account Manager.
