There may be energy procurement opportunities for the Freehold RHSD Howell High School to
reduce annual utility costs, which are $20,968 higher, when compared to the average estimated NJ
commercial utility rates.
SWA has also entered energy information about the Howell High School in the U.S. Environmental
Protection Agency’s (EPA) ENERGY STAR® Portfolio Manager Energy benchmarking system. This
high school is comprised of K-12 School space type. The resulting score is 45, which is slightly
more than the average comparable school building by 3.5%.
Based on the current state of the building and its energy use, SWA recommends implementing
various energy conservation measures from the savings detailed in Table 1. The measures are
categorized by payback period in Table 2 below:

INTRODUCTION
Launched in 2008, the Local Government Energy Audit (LGEA) Program provides subsidized
energy audits for municipal and local government-owned facilities, including offices, courtrooms,
town halls, police and fire stations, sanitation buildings, transportation structures, schools and
community centers. The Program will subsidize up to 100% of the cost of the audit. The Board of
Public Utilities (BPUs) Office of Clean Energy has assigned TRC Energy Services to administer the
Program.
Steven Winter Associates, Inc. (SWA) is a 38-year-old architectural/engineering research and
consulting firm, with specialized expertise in green technologies and procedures that improve the
safety, performance, and cost effectiveness of buildings. SWA has a long-standing commitment to
creating energy-efficient, cost-saving and resource-conserving buildings. As consultants on the built
environment, SWA works closely with architects, developers, builders, and local, state, and federal
agencies to develop and apply sustainable, ‘whole building’ strategies in a wide variety of building
types: commercial, residential, educational and institutional.
SWA performed an energy audit and assessment for the Howell High School at 405 SquankumYellowbrook Road, Farmingdale, NJ 07727. The process of the audit included facility visits on May
6 and June 28, 2010, benchmarking and energy bills analysis, assessment of existing conditions,
energy modeling, energy conservation measures and other recommendations for improvements.
The scope of work includes providing a summary of current building conditions, current operating
costs, potential savings, and investment costs to achieve these savings. The facility description
includes energy usage, occupancy profiles and current building systems along with a detailed
inventory of building energy systems, recommendations for improvement and recommendations for
energy purchasing and procurement strategies.
The goal of this Local Government Energy Audit is to provide sufficient information to the Freehold
RHSD to make decisions regarding the implementation of the most appropriate and most costeffective energy conservation measures for the Howell High School.

HISTORICAL ENERGY CONSUMPTION
Energy usage, load profile and cost analysis
SWA reviewed utility bills from February 2008 through February 2010 that were received from
the utility companies supplying the Howell High School with electric and natural gas. A 12 month
period of analysis from March 2009 through February 2010 was used for all calculations and for
purposes of benchmarking the building.
Electricity - The Howell High School is currently served by one electric meter. The Howell High
School currently buys electricity from JCP&L at an average aggregated rate of $0.157/kWh.
The Howell High School purchased approximately 2,637,200 kWh, or $414,416 worth of
electricity, in the previous year. The average monthly demand was 635.0 kW and the annual
peak demand was 718.0 kW.
The chart below shows the monthly electric usage and costs. The dashed green line represents
the approximate baseload or minimum electric usage required to operate the Howell High
School.
Natural gas - The Howell High School is currently served by one meter for natural gas. The
Howell High School currently buys natural gas from NJ Natural Gas at an average aggregated
rate of $1.565/therm. The Howell High School purchased approximately 138,274 therms, or
$216,394 worth of natural gas, in the previous year.

Energy benchmarking
SWA has entered energy information about the Howell High School in the U.S. Environmental
Protection Agency’s (EPA) ENERGY STAR® Portfolio Manager Energy benchmarking system.
This high school is categorized as a K-12 School space type. The Howell High School received
a national energy performance rating of 45. The Site Energy Use Intensity is 89.0 kBtu/ft2-yr
compared to the national average of a school building consuming 86.0 kBtu/ft2-yr. See ECM
section for guidance on how to improve the building’s rating.
Per the LGEA program requirements, SWA has assisted the Freehold RHSD to create an
ENERGY STAR® Portfolio Manager account and share the Howell High School facilities
information to allow future data to be added and tracked using the benchmarking tool. SWA has
shared this Portfolio Manager account information with the Freehold RHSD (user name of
“frhsd8579” with a password of “frhsd8579”) and TRC Energy Services (user name of “TRCLGEA”).
Tariff analysis
As part of the utility bill analysis, SWA evaluated the current utility rates and tariffs. Tariffs are
typically assigned to buildings based on size and building type.
Tariff analysis is performed to determine if the rate that Freehold RHSD is contracted to pay
with each utility provider is the best rate possible resulting in the lowest costs for electric and
gas provision. Typically, the natural gas prices increase during the heating months when
natural gas is used by the hot water boiler units. Some high gas price per therm fluctuations in
the summer may be due to high energy costs that recently occurred and low use caps for the
non-heating months. Typically, electricity prices also increase during the cooling months when
electricity is used by the HVAC condensing units and air handlers.
Steven Winter Associates, Inc. - LGEA Final Report
Freehold RHSD-Howell High School
Page 10/111
The supplier charges a market-rate price based on use, and the billing does not break down
demand costs for all periods because usage and demand are included in the rate. Currently, the
Freehold RHSD is paying a general service rate for natural gas. Demand is not broken out in
the bill. Thus the building pays for fixed costs such as meter reading charges during the summer
months. The building is direct metered and currently purchases electricity at a general service
rate for usage with an additional charge for electrical demand factored into each monthly bill.
The general service rate for electric charges is market-rate based on usage and demand.
Demand prices are reflected in the utility bills and can be verified by observing the price
fluctuations throughout the year.
Energy Procurement strategies
Billing analysis is conducted using an average aggregated rate that is estimated based on the
total cost divided by the total energy usage per utility per 12 month period. Average aggregated
rates do not separate demand charges from usage, and instead provide a metric of inclusive
cost per unit of energy. Average aggregated rates are used in order to equitably compare
building utility rates to average utility rates throughout the state of New Jersey.
The average estimated NJ commercial utility rates for electric are $0.150/kWh, while Howell
High School pays a rate of $0.157/kWh. The Howell High School annual electric utility costs are
$18,836 higher, when compared to the average estimated NJ commercial utility rates. Electric
bill analysis shows fluctuations up to 4% over the most recent 12 month period.
Steven Winter Associates, Inc. - LGEA Final Report
Freehold RHSD-Howell High School
Page 11/111
The average estimated NJ commercial utility rates for gas are $1.550/therm, while Howell High
School pays a rate of $1.565/therm. The Howell High School annual natural gas utility costs are
$2,131 higher, when compared to the average estimated NJ commercial utility rates. Natural
gas bill analysis shows fluctuations up to 80% over the most recent 12 month period.
Utility rate fluctuations may have been caused by adjustments between estimated and actual
meter readings; others may be due to unusual high and recent escalating energy costs and
constant meter charges combined with low usage.
SWA recommends that the Howell High School further explore opportunities of purchasing both
natural gas and electricity from third-party suppliers in order to reduce rate fluctuation and
ultimately reduce the annual cost of energy for the Howell High School. Appendix C contains a
complete list of third-party energy suppliers for the Freehold RHSD service area.

Page 13/111
Exterior Walls
The exterior wall envelope is mostly constructed of brick veneer and some limestone type
accents over concrete block with 2 inches of fiberglass batt cavity insulation. Other more
recent additions are insulated with 1 inch of foam board insulation. The interior is mostly
painted gypsum wallboard or painted concrete block.
Note: Wall insulation levels could not be verified in the field and are based on available
construction plans.
Exterior and interior wall surfaces were inspected during the field audit. They were found to
be in overall acceptable, age-appropriate condition with only a few signs of uncontrolled
moisture, air-leakage or other energy-compromising issues.
The following specific exterior wall problem spots and areas were identified:
Signs of water
Un-caulked/un-sealed exterior wall penetrations
damage at perimeter
walls due to defective
gutter or downspout.
Roof
The building’s roof is predominantly a flat and parapet type over steel decking with a built-up
asphalt finish and reflective stone coating. It is original to the building. Two and a half inches
of foam board roof insulation were recorded. Also about two and a half inches of under roof
deck applied spray cellulose ceiling insulation were added to some parts of the original
building a few years ago. Other parts of the building are also covered by a recently updated
dark colored EPDM single membrane finish.
Note: Roof insulation levels could not be verified in the field, and are based on available
construction plans.
Roofs, related flashing, gutters and downspouts were inspected during the field audit. They
were reported to be in overall acceptable, age-appropriate condition, with only a few signs of
uncontrolled moisture, air-leakage or other energy-compromising issues.
The following specific roof problem spots were identified:
Steven Winter Associates, Inc. - LGEA Final Report
Freehold RHSD-Howell High School
Page 14/111
Rocks/nails or other sharp objects on roof surface were detected.
Small roof leaks in most parts of the building were reported.
Base
The building’s base is composed of a slab-on-grade floor with a perimeter foundation and no
detectable slab edge/perimeter insulation.
Slab/perimeter insulation levels could not be verified in the field and are based on available
construction plans.
The building’s base and its perimeter were inspected for signs of uncontrolled moisture or
water presence and other energy-compromising issues. Overall the base was reported to be
in acceptable condition with no signs of uncontrolled moisture, air-leakage and/or other
energy-compromising issues except for reports of condensation on ground floor finishes
during hot and humid outside conditions.
Windows
The building contains basically two different types of windows.
1. Casement type windows with a non-insulated aluminum frame, clear single glazing and
some interior shading devices. The windows are located throughout the building and are
original.
2. Casement type windows with a non-insulated aluminum frame, clear double glazing and
interior roller blinds. The windows are located throughout the building. Window updates
started about 10 years ago but have been on hold for a while now due to lack of funding.
Windows, shading devices, sills, related flashing and caulking were inspected as far as
accessibility allowed for signs of moisture, air-leakage and other energy compromising
issues. Overall, the windows were found to be in acceptable condition with only a few signs
of uncontrolled moisture, air-leakage and/ or other energy-compromising issues.
The following specific window problem spots were identified:

Exterior doors
The building contains only one type of exterior door.
1. Aluminum/steel frame with safety glass type exterior doors. They are located throughout the
building and are original.
All exterior doors, thresholds, related flashing, caulking and weather-stripping were
inspected for signs of moisture, air-leakage and other energy-compromising issues. Overall,
the doors were found to be in acceptable, age appropriate condition with no signs of
uncontrolled moisture, air-leakage and/ or other energy-compromising issues.
Building air-tightness
Overall the field auditors found the building to be reasonably air-tight with only a few areas
of suggested improvements, as described in more detail earlier in this chapter.
The air tightness of buildings helps maximize all other implemented energy measures and
investments, and minimizes potentially costly long-term maintenance, repair and
replacement expenses.
Mechanical Systems
Heating Ventilation Air Conditioning
The building is heated by two boiler plants, with cooling and/or ventilation provided by a
combination of rooftop units, heating and ventilating units and exhaust fans for the common
and office areas, and unit ventilators for many of the classrooms. Some of the unit
ventilators contain a split system DX cooling component but most are heating and ventilating
only. The original boiler plant in the 1963 building provides heating to the original building
and the 1979 additions. These portions of the building include A, B and C Wings and the
Auditorium, Gymnasium B100, Gymnasium B101, Cafeteria, Media Center, Guidance
Offices and Main Offices. The D Wing was added in 2001 and contains its own boiler plant.
It should be noted that a good portion of the school HVAC systems are still controlled by the
Barber Coleman Automatic Temperature Controls (ATC) systems. The D Wing Addition and
partial renovations to A Wing and B Wing, and a few second floor C Wing Rooms contain a
Johnson Metasys digital ATC system in those portions of the building. There are also some
Honeywell and Powers thermostats scattered throughout the school. It was reported that the
Barber Coleman/Andover system provides poor temperature control.

Equipment
Howell High School has undergone several renovations and one addition since the original
building was constructed in 1964. With each renovation or addition, there has been
equipment added to condition the affected portion of the building. The following paragraphs
contain a summary of the systems in the various portions of the building. A comprehensive
Equipment List can be found in Appendix A.
The Auditorium contains two (2) air handling units suspended from the roof deck above the
stage that provide heating and ventilation. Heating is provided by hot water coils in the units
that are fed by the building’s original boiler plant. There are also two (2) 15-ton cooling only
packaged RTUs providing cooling to the space. The air handling units appear to be original
to the building and replacement should be considered. The RTUs were installed in 2006 and
are in very good condition. There are also rooftop exhaust fans above the Auditorium to
exhaust rooms A111-115, the toilet rooms in Auditorium lobby and the SECA Office.
One of Two American Standard Rooftop Units Serving the Auditorium
Rooms A104-A117 are heated and ventilated only via Nesbitt unit ventilators that are
original to the building. These units are in fair to poor condition, are well beyond their
expected service life and should be replaced. Rooms A100-A103 were renovated with the
addition of the D Wing in 2001. These Rooms and the classrooms in D Wing, except D112
and D114, are conditioned by cooling only packaged rooftop units with hot water heating
coils located in the supply air ductwork below the roof deck. Rooms D112 and D114 contain
through wall, floor-mounted unit ventilators with DX cooling. All equipment and ductwork is
in good condition.
The Main Gymnasium is heated and ventilated by finned tube radiation and four exhaust
fans, two located high on each of the long walls. The Auxiliary Gymnasium B101 is heated
and ventilated via one (1) large H&V unit located above the adjacent locker rooms. This
gymnasium is exhausted by multiple rooftop exhaust fans. The Auxiliary Gym D100 is
heated and ventilated by two large rooftop H&V units with hot water heating coils located in
the supply air ductwork below the roof deck. The locker rooms that are adjacent to these
gyms are heated and ventilated by air handling units with hot water coils. These units are
located in the ceiling above the rooms, or in adjacent Storage rooms. The H&V unit in B101
and air handling units in the locker rooms are original to the building and have exceeded

Freehold RHSD-Howell High School
Page 17/111
their expected service lives. This equipment should be replaced as part of a capital
improvement plan in the district.
The Gym Offices and Wrestling Room and are conditioned by rooftop DX cooling, heating
and ventilating RTUs added in 2002. The Dance Studio is heated, cooled and ventilated by
a built up rooftop H&V unit with split condensing unit added in 2002. Music Room B104 and
adjacent offices and storage rooms are conditioned by packaged RTUs added in 2006.
Music Room B105 is heated and ventilated only but contains a wall-mounted ductless split
system to provide some cooling. Based on the size of this equipment, it is likely to be
inadequate for the room and should be replaced with another RTU similar to that in Room
B104.
The Cafeteria is heated and ventilated by rooftop H&V units and exhaust fans. This
equipment was added in 2002 and is in good condition. The Faculty Dining Area behind the
Kitchen was added in 2002 and is heated, cooled and ventilated by a packaged rooftop unit
that is in good condition. The Kitchen hood receives dedicated makeup air from rooftop H&V
units located above the Cafeteria.
The Media Center and its ancillary offices are heated, cooled and ventilated by one large
35-ton RTU manufactured in 1981. This unit is in poor condition and is operating well
beyond its expected service life. Based on the odor experienced in the Media Center, there
is a possibility that the unit is not adequately dehumidifying the space. This unit should be
replaced with multiple units to offer redundancy and reliability, as well as an increase in
operating efficiency.
The Main Office is heated, ventilated and cooled by a packaged, constant volume rooftop
unit located above the Media Center. The unit utilizes hot water heating and DX cooling.
This equipment was added in 1981, is operating well beyond its expected service life and
should be replaced. Replacement should provide an increase in cooling efficiency. The
Guidance Office and adjacent Media Center Rooms are heated, ventilated and cooled by
two (2) Trane rooftop units that were installed in 2002. There is a hot water coil in the
ductwork below, and DX cooling in the unit. The units are in good condition and can be
retained for another 6-7 years.

Classrooms B106-B112 are heated, cooled and ventilated by multiple RTUs that were
added in 2000. This equipment is in good condition and can be retained for another 4-5
years.
The Nurse’s Office, Attendance Office and adjacent rooms are heated, cooled and
ventilated by original finned-tube radiation and window air conditioning units. This equipment
is in fair condition and should be replaced.
Classrooms A207-A217 contain 1964 (Nesbitt) unit ventilators for heating and ventilation,
and are cooled by wall-mounted ductless split system air conditioning units. The unit
ventilators are operating beyond their expected service lives, and should be replaced. The
ductless split systems can be retained for another 3-5 years, but replacement would bring
energy savings.
The remainder of the classrooms in the A and C Wings are heated and ventilated by floor
mounted or ceiling mounted unit ventilators installed in either 1964 (Nesbitt) or 1979
(Trane), with the exception of Rooms A202 and C203, 205, 213, 214, 216. These
classrooms contain newer unit ventilators with split system DX cooling.
Original 1964 Nesbitt (Left) and 1979 Trane Unit Ventilators
In general, the rooftop units in this building contain a direct expansion (DX) system for
cooling, made up of an evaporator, condenser and refrigerant loop. The heating section
consists of a hydronic (hot water) coil located in the supply ductwork below the roof deck. In
cooling mode, the refrigerant absorbs heat from the passing air in the evaporator coil and
transfers the heat to the atmosphere in the condenser. Much of the equipment contains
refrigerant R-22, which contains CFCs and is being phased out of production for
environmental reasons. Newer equipment will contain refrigerant R-410A, which is more
environmentally-friendly than R-22.
The rooftop units draw in outside air directly, providing a means of ventilation without an
additional building penetration above that required for the distribution ductwork.
The H&V unit and RTU heating coils, unit ventilators, hydronic unit heaters and finned-tube
radiation located in the A, B and C Wings of the building are provided with heating hot water
by two (2) Superior packaged fire-tube boilers located in the original boiler room. These
boilers were installed in 1963 and are in fair to poor condition. This equipment is operating
Steven Winter Associates, Inc. - LGEA Final Report
Freehold RHSD-Howell High School
Page 19/111
well beyond its expected life of 30 years per the 2007 ASHRAE Applications Handbook. The
thermal efficiency of this equipment can be expected to be approximately 65%.
The Superior boilers produce heating hot water that is pumped by one of three floormounted to the A, B, and C Wings. One of the three original pumps is run at a time and is
usually sufficient to handle the heating load. On days with particularly cold outside air
temperatures, a second pump will be run as well. These pump motors are recommended to
be replaced with premium efficiency motors in the ECM section of this report. In addition, it
is recommended that the operation of the three-way valve at each boiler is checked since it
failure of this valve can cause the existing outside temperature hot water reset controls to
not function effectively.
The Original 1964 Superior Boilers
The hydronic unit heaters, duct-mounted heating coils and finned-tube radiation located in
the D Wing (2001 addition) and a small adjacent portion of the A Wing are provided with
heating hot water by two (2) Aerco Benchmark 2.0 condensing boilers located in a boiler
room adjacent to Room D104. The boilers were installed in 2002 and are in very good
condition. This equipment is almost one third of its way through its expected service life of
30 years. The efficiency of this equipment can range from about 80-93%. In general,
condensing boilers are most efficient when operating at temperatures that are lower than
non-condensing or cast iron boilers.
The Aerco boilers produce heating hot water that is pumped by a pair of floor-mounted
pumps in the D Wing Boiler Room. These pumps are in very good condition. The pump
motors are standard efficiency and are recommended to be replaced with premium
efficiency motors in the ECM section of this report.
There are several exhaust fans located on the roof, which serve the bathrooms, kitchen
hood and general exhaust. The fans vary in age and condition, but were all operating at the
time of the field visit. In general, most of the building exhaust fans have an estimated 0-50%
useful operating life left.

Some of the classrooms and the offices in the Nurse’s Office area contain window air
conditioners, most of which are not ENERGY STAR° rated. SWA recommends that this
equipment is replaced with equipment that is ENERGY STAR° rated.
The Two Aerco Condensing Boilers in the 2002 Boiler Room
Distribution Systems
The heating hot water produced in both boiler rooms is distributed via pumps and copper
piping to the H&V unit coils, unit ventilators, finned-tube radiators, unit heaters and cabinet
unit heaters scattered throughout the building. The Superior boilers are piped in a primary
pumping arrangement. The floor-mounted pumps in the boiler room operate in a lead-lag
fashion to distribute the water to various heating zones throughout the A, B and C Wings of
the building. The Aerco boilers are piped in a primary pumping arrangement, with two (2)
floor-mounted pumps delivering the water to the terminal equipment in the D Wing of the
building. These pumps operate in lead-lag fashion, and usually one pump can satisfy the
heating load in this area of the building.

Examples of Pumps in the Original Boiler Room (Left) and in the 2002 Boiler Room
A typical rooftop unit arrangement draws in fresh air and brings it into a mixing box, where it
is combined with return air from the building. A small portion of the return air is purged and
vented outside prior to entering the mixing box. The mixed air inside the air handler is sent
through a filter before passing through the evaporator or direct expansion (DX) coil. The air
handler fan then pushes the air through the duct-mounted hot water coil before the
conditioned air is distributed into the building spaces. The hot water coil is only active in the
heating season and the DX system is only active in the cooling season. In between these
seasons neither system may operate and only the blower will be active to provide fresh air
to the building. In a few cases in this building, the rooftop equipment did not contain the DX
cooling coil mentioned above.
Example of Hot Water Piping Leading to Duct-Mounted Hot Water Coil in D Wing
Howell High School has constant air volume systems as described above. Typically, with
this type of arrangement, the outside air damper is opened and the supply fan runs
constantly during occupied hours, and the outside air damper is closed and the supply fan
cycles when heating or cooling is required during unoccupied hours. The heating coils
contain a control valve that opens to let heating water into the hot water coil upon a heating
call from the thermostat. Upon a call for cooling, the DX compressor in the RTU is operated
to provide cooling.
There is one (1) large commercial kitchen exhaust hood over the ovens and range in the
kitchen. The makeup air for this hood is provided by H&V units located on the roof above the
Cafeteria and transferred via grilles that are located high on the wall between the Kitchen

and the Cafeteria. The H&V units are provided with heating hot water and are in relatively
good condition.
Controls
There are two different Automatic Temperature Controls (ATC) systems within the building.
A good portion of the school HVAC systems are still controlled by the Barber
Coleman/Andover Automatic Temperature Controls (ATC) systems that were installed in
1964 and modified over the years. It was reported that the Barber Coleman/Andover
controls provide poor overall temperature control. The system is monitored by Jersey State
Controls, and limited control of the equipment on this system is provided via desktop
computer in the Maintenance Office. The D Wing Addition and partial renovations to A Wing
and B Wing and a few second floor C Wing Rooms contain a Johnson Controls Metasys
digital ATC system. These thermostats are connected to small Johnson Controls Metasys
direct digital control (DDC) ATC panels located in the maintenance office, D Wing Boiler
Room, and a few other strategic locations.
There are also some Honeywell and Powers thermostats scattered throughout the school
but it was not determined if these thermostats are standalone or connected to the Barber
Coleman/Andover ATC system.
The D Wing boilers are provided with an Aerco boiler control panel.

Some Examples of the Various Thermostats Encountered in the Building
The different controls listed above do not provide one consistent control scheme throughout
the school.
SWA recommends that one uniform ATC system is provided for the school. A logical
approach for the district would be to combine and build on the existing Johnson Controls
Metasys ATC systems to provide one comprehensive ATC system. This would allow
salvaging of the controls equipment in a significant portion of the school.
Domestic Hot Water
The domestic hot water (DHW) for the school is provided by one (1) Cleaver Brooks
packaged fire-tube boiler and adjacent storage tank located in the Original Boiler Room. The
boiler was installed in 1981, and is at the end of its expected service life. This system is
provided with re-circulating pumps to provide a constant supply of domestic hot water
throughout the building. This reduces water consumption by eliminating the need to wait for
hot water.
Domestic Water Heater and External Storage Tank in Original Boiler Room
There is also a 45 KW electric booster heater at the dishwasher in the kitchen. This
equipment is in fair condition and should be considered for replacement. Replacement
would not provide energy savings, but if gas-fired equipment is used, it is likely that
operating costs would be reduced.
Commercial Refrigeration
The school also has an approximately 8’ x 10’ walk-in cooler inside the kitchen. This cooler
was manufactured by Bally and appears to be original to the building (1964). The equipment
Steven Winter Associates, Inc. - LGEA Final Report
Freehold RHSD-Howell High School
Page 24/111
is in fair condition. Although the unit was locked and nameplate data was not accessible, it is
assumed that there is a savings opportunity from changing the evaporator fan section to a
more modern model.
The school also has an approximately 8’ x 8’ walk-in cooler inside the kitchen. This cooler
was manufactured by Bally and based on its condition; it is estimated to have been added in
the 1980s. The equipment is in fair to good condition, and appears to have been partially
refurbished within the last few years. Although the unit was locked and nameplate data was
not accessible, the evaporator fans appeared to be a more modern model than what was
witnessed through the window of the door of the original cooler mentioned above.
Accessible via the cooler is a walk-in freezer of similar size to the cooler. This freezer is also
estimated to have been added in the 1980s and is in similar condition to the cooler. It is
assumed that the evaporator fans are of a similar model to those in the cooler and that they
are fairly efficient.
Several of the rooms adjacent to the newer walk-in box were locked and inaccessible during
the survey. Therefore, it is not known if any of the adjacent rooms also contained an
evaporator section to provide cold storage, as witnessed in some of the other schools in this
district. If so, this area could be studied separately to identify other potential savings
opportunities.
Original Walk-In Cooler Box (Left) and 1980s Walk-In Cooler/Freezer
The kitchen contains four (4) stainless steel refrigerators, two (2) chest freezers, one (1)
chest cooler and several glass door merchandisers. All equipment appears to be in relatively
good condition.

As of July 1, 2010 magnetic ballasts most commonly used for the operation of T12 lamps
will no longer be produced for commercial and industrial applications. Also, many T12 lamps
will be phased out of production starting July 2012.
Interior Lighting - The Howell High School currently contains a mixture of T12 fixtures, T8
fixtures, and self-ballast bulbs including incandescent bulbs and CFLs. There were some
observed high pressure sodium and metal halide fixtures found in the wrestling room and
the media center. Based on measurements of lighting levels for each space, there are no
vastly over-illuminated areas.
Exit Lights - Exit signs were found to contain both fluorescent and LED lamps.
Exterior Lighting - The exterior lighting surveyed during the building audit was found to be a
mix of Metal Halide lamp and CFL fixtures. Exterior lighting is controlled by timers.
Appliances and process
SWA has conducted a general survey of larger, installed equipment. Appliances and other
miscellaneous equipment account for a significant portion of electrical usage within the
building. Typically, appliances are referred to as “plug-load” equipment, since they are not
inherent to the building’s systems, but rather plug into an electrical outlet. Equipment such
as process motors, computers, computer servers, radio and dispatch equipment,
refrigerators, vending machines, printers, etc. all create an electrical load on the building
that is hard to separate out from the rest of the building’s energy usage based on utility
analysis.
Elevators
Howell High School contains one (1) hydraulic elevator in C Wing. The hydraulic machine
was manufactured by Dover in 1981 and is 20 horsepower. It is recommended that further
study is undertaken to confirm that the elevator meets current code, and that the required
upgrades are performed to bring the elevator into compliance.
Generator
There is one (1) Onan 100 KW natural gas emergency generator located just outside the
original boiler room. This generator was installed in 1994. This generator is in fair condition
overall and has been well maintained considering its age.

RENEWABLE AND DISTRIBUTED ENERGY MEASURES
Renewable energy is defined as any power source generated from sources which are naturally
replenished, such as sunlight, wind and geothermal. Technology for renewable energy is improving,
and the cost of installation is decreasing, due to both demand and the availability of
state and federal government-sponsored funding. Renewable energy reduces the need for using
either electricity or fossil fuel, therefore lowering costs by reducing the amount of energy purchased
from the utility company. Technology such as photovoltaic panels or wind turbines, use natural
resources to generate electricity on the site. Geothermal systems offset the thermal loads in a
building by using water stored in the ground as either a heat sink or heat source. Solar thermal
collectors heat a specified volume of water, reducing the amount of energy required to heat water
using building equipment. Cogeneration or CHP allows you to generate electricity locally, while also
taking advantage of heat wasted during the generation process.
Existing systems
Currently there are no renewable energy systems installed in the building.
Evaluated Systems
Solar Photovoltaic
Photovoltaic panels convert light energy received from the sun into a usable form of electricity.
Panels can be connected into arrays and mounted directly onto building roofs, as well as
installed onto built canopies over areas such as parking lots, building roofs or other open areas.
Electricity generated from photovoltaic panels is generally sold back to the utility company
through a net meter. Net-metering allows the utility to record the amount of electricity generated
in order to pay credits to the consumer that can offset usage and demand costs on the electric
bill. In addition to generation credits, there are incentives available called Solar Renewable
Energy Credits (SRECs) that are subsidized by the state government. Specifically, the New
Jersey State government pays a market-rate SREC to facilities that generate electricity in an
effort to meet state-wide renewable energy requirements.
Based on utility analysis and a study of roof conditions, Howell High School is a good candidate
for a 48.07 kW or 158.47 kW Solar Panel installation. See ECM# 17 and 18 for details.
Solar Thermal Collectors
Solar thermal collectors are not cost-effective for this building and would not be recommended
due to the insufficient and intermittent use of domestic hot water throughout the building to
justify the expenditure.
Wind
The Howell High School is not a good candidate for wind power generation due to insufficient
wind conditions in this area of New Jersey.
Steven Winter Associates, Inc. - LGEA Final Report
Freehold RHSD-Howell High School
Page 28/111
Geothermal
Howell High School is not a good candidate for geothermal installation since it would require
replacement of the entire existing HVAC system, of which major components still have between
50% and 95% remaining useful life.
Combined Heat and Power
Howell High School is not a good candidate for CHP installation and would not be cost-effective
due to the size and operations of the building. Typically, CHP is best suited for buildings with a
high electrical baseload to accommodate the electricity generated, as well as a means for using
waste heat generated. Typical applications include buildings with an absorption chiller, where
waste heat would be used efficiently.

ECM#1: Install 10 Drinks and 3 Snack Misers on Vending Machines
Description:
The Howell High School building has ten drink vending machines and three snack vending
machines. Energy vending miser devices are now available for conserving energy with these
machines. There is no need to purchase new machines to reduce operating costs and greenhouse
gas emissions. When equipped with the vending miser devices, refrigerated beverage vending
machines or coolers use less energy and are comparable in daily energy performance to new
ENERGY STAR® qualified machines. Vending miser devices incorporate innovative energy-saving
technology into small plug-and-play devices that install in minutes, either on the wall or on the
vending machine. Vending miser devices use a Passive Infrared Sensor (PIR) to: power down the
machine when the surrounding area is vacant; monitor the room's temperature; automatically
repower the cooling system at one to three hour intervals, independent of sales; ensure the product
stays cold.
Vending machines found throughout Howell High School
Snacks vending miser devices can be used on snacks vending machines to achieve maximum
energy savings that result in reduced operating costs and decreased greenhouse gas emissions
with existing machines. Snacks vending miser devices also use a Passive Infrared Sensor (PIR) to
determine if there is anyone within 25 feet of the machine. It waits for 15 minutes of vacancy, then
powers down the machine. If a customer approaches the machine while powered down, the snacks
vending miser will sense the presence and immediately power up.

ECM#6: Replace 3 Old Refrigerators with ENERGY STAR® Models
On the days of the site visit, SWA observed older refrigerators in the foods classroom, custodial
break room, and in the kitchen that are not ENERGY STAR® rated (using as much as 840 kWh/yr).
SWA auditors could not confirm the energy usage of many of the smaller refrigerators located
throughout the building. SWA high recommends the Regional High School District consider
replacement of all refrigerators over 10-12 years of age with more modern, ENERGY STAR®,
energy efficient appliances. In addition to saving energy, the replacements will also keep the
refrigerator locations cooler. Furthermore, the older model refrigerators may utilize R-12 refrigerant,
which is not an ozone-friendly refrigerant. Newer systems should be specified with R-134A or R404A refrigerant. When compared to the average electrical consumption of older equipment,
ENERGY STAR® equipment results in large savings. Look for the ENERGY STAR® label when
replacing appliances and equipment, including window air conditioners, refrigerators, printers,
computers, copy machines, etc. More information can be found in the “Products” section of the
ENERGY STAR® website at: http://www.energystar.gov.

ECM#7: Install 193 New Occupancy Sensors
On the day of the site visit, SWA observed that the Howell High School contained few locations of
lighting installations that were operated via occupancy sensors. SWA recommends installing
occupancy sensors in bathrooms, closets, offices and areas that are occupied only part of the day,
and where payback on savings is justified. Typically, occupancy sensors have an adjustable time
delay that shuts down the lights automatically if no motion is detected within a set time period.

ECM#14: Retro-commissioning
Retro-commissioning is a process that seeks to improve how building equipment and systems
function together. Depending on the age of the building, retro-commissioning can often resolve
problems that occurred during design or construction and/or address problems that have developed
throughout the building’s life. Owners often undertake retro-commissioning to optimize building
systems, reduce operating costs, and address comfort complaints from building occupants.
Since the systems in the building have undergone some renovations in recent years, and the
occupants continue to have concerns with thermal comfort control, SWA recommends undertaking
retro-commissioning to optimize system operation as a follow-up to completion of the upgrades.
The retro-commissioning process should include a review of existing operational parameters for
both newer and older installed equipment. During retro-commissioning, the individual loop
temperatures and (setback) schedules should also be reviewed to identify opportunities for
optimizing system performance, besides air balancing and damper proper operation. New controls
as well as any HVAC ECM measures should be implemented before retro-commissioning.

Assumptions: SWA calculated the savings for this measure using measurements taken during the
field audit and using the billing analysis. Since the utility bills have some accounting fluctuations, it
is difficult to determine the amount of energy used for building heating and cooling . Based on
experience with similar buildings, SWA estimated the heating and cooling energy consumption.
Typical savings for retro-commissioning range from 5-20%, as a percentage of the total space
conditioning consumption. SWA assumed 10% savings. Estimated costs for retro-commissioning
range from $0.50-$2.00 per square foot. SWA assumed $(1.00 or 1.25 or 0.75) per square foot of a
total building square footage. SWA also assumed on the average 1 hr/wk operational savings when
systems are operating per design vs. the need to make more frequent adjustments.

ECM#15: Replace (2) 8,369 MBH Input Boilers with (4) 2000 MBH Input 96% Efficient,
Condensing Boilers
The existing (2) fire-tube Superior boilers in the Original Boiler room were installed in 1963 and are
in fair condition. The boilers are relatively inefficient as compared to modern boilers. No outdoor
temperature reset controls were observed. The boilers should be considered for replacement to
achieve energy savings as well as operating and maintenance savings. The initial efficiency of the
existing boilers are approximately 80%, but it can be assumed that in the time since installation, it
has degraded to an efficiency of about 65%. An upgrade to (4) higher efficiency, condensing boilers
of minimum 85% combustion efficiency each should be considered by the Howell High School as a
means of energy conservation.
The new high efficiency condensing boilers should have a guaranteed minimum thermal efficiency
of 85% at the worst case boiler operating conditions, such as mid-fire or high-fire conditions with a
return water temperature in the range of 140-160 degrees Fahrenheit, and efficiencies of up to 95%
achievable with lower return water temperatures. The boiler should be Low NOx certified with a 5:1
turndown burner, PVC direct venting and direct exhaust, hydronic safety controls and interface
systems. The boiler shall have compact design for easy retrofit installation, with sectional aluminum

ECM#17: Install 48.07 kW PV Rooftop System with Incentives
Currently, the building does not use any renewable energy systems. Renewable energy systems
such as photovoltaic (PV) panels can be mounted on the building roof facing south which can offset
a portion of the purchased electricity for the building. Power stations generally have two separate
electrical charges: usage and demand. Usage is the amount of electricity in kilowatt-hours that a
building uses from month to month. Demand is the amount of electrical power that a building uses
at any given instance in a month period. During the summer periods, electric demand at a power
station is high, due to the amount of air conditioners, lights, and other equipment being used within
the region. Demand charges increase to offset the utility’s cost to provide enough electricity at that
given time. Photovoltaic systems offset the amount of electricity used by a building and help to
reduce the building’s electric demand, resulting in a higher cost savings. Installing a PV system will
offset electric demand and reduce annual electric consumption, while utilizing available state
incentives. PV systems are modular and readily allow for future expansions.
The size of the system was determined considering the available roof surface area, without
compromising service space for roof equipment and safety, as well as the facilities’ annual base
load and mode of operation. A PV system could be installed on a portion of the roof with panels
facing south. A commercial multi-crystalline 230 watt panel has 17.5 square feet of surface area
(providing 13.1 watts per square foot). A 48.07 kW system needs approximately 209 panels which
would take up 3,666 square feet. The larger 158.47 kW system would require approximately 689
panels which would take up 12,086 square feet.
A PV system would reduce the building's electric load and allow more capacity for surrounding
buildings as well as serve as an example of energy efficiency for the community. The building is

applying for a grant and / or engage a PV generator / leaser who would install the PV system and
then sell the power at a reduced rate. Typically, a major utility provides the ability to buy SREC’s at
$600/MWh or best market offer.
Two different system sizes were proposed due to installation incentives only being offered for
systems less than 50kW in size. The first option takes advantage of these incentives by staying
below the 50kW system threshold, and the second option takes advantage of the total usable space
on the school’s roof to install a PV system. SWA recommends installing the larger system;
however, if sufficient funding is not available, the Howell High School should at least install the
48.07 kW system. As mentioned above, these systems are modular and can be expanded in the
future.
Please note that this analysis did not consider the structural capability of the existing building to
support the above recommended system. SWA recommends that the Howell High School contract
with a structural engineer to determine if additional building structure is required to support the
recommended system and what costs would be associated with incorporating the additional
supports prior to system installation. Should additional costs be identified, the Howell High School
should include these costs in the financial analysis of the project.

ECM#18: Install 158.47 kW PV Rooftop System without Incentives
Currently, the building does not use any renewable energy systems. Renewable energy systems
such as photovoltaic (PV) panels can be mounted on the building roof facing south which can offset
a portion of the purchased electricity for the building. Power stations generally have two separate
electrical charges: usage and demand. Usage is the amount of electricity in kilowatt-hours that a
building uses from month to month. Demand is the amount of electrical power that a building uses
at any given instance in a month period. During the summer periods, electric demand at a power
station is high, due to the amount of air conditioners, lights, and other equipment being used within
the region. Demand charges increase to offset the utility’s cost to provide enough electricity at that
given time. Photovoltaic systems offset the amount of electricity used by a building and help to
reduce the building’s electric demand, resulting in a higher cost savings. Installing a PV system will
offset electric demand and reduce annual electric consumption, while utilizing available state
incentives. PV systems are modular and readily allow for future expansions.
The size of the system was determined considering the available roof surface area, without
compromising service space for roof equipment and safety, as well as the facilities’ annual base
load and mode of operation. A PV system could be installed on a portion of the roof with panels
facing south. A commercial multi-crystalline 230 watt panel has 17.5 square feet of surface area
(providing 13.1 watts per square foot). A 48.07 kW system needs approximately 209 panels which
would take up 3,666 square feet. The larger 158.47 kW system would require approximately 689
panels which would take up 12,086 square feet.
A PV system would reduce the building's electric load and allow more capacity for surrounding
buildings as well as serve as an example of energy efficiency for the community. The building is
not eligible for a residential 30% federal tax credit. The Howell High School may want to consider
applying for a grant and / or engage a PV generator / leaser who would install the PV system and
then sell the power at a reduced rate. Typically, a major utility provides the ability to buy SREC’s at
$600/MWh or best market offer.
Two different system sizes were proposed due to installation incentives only being offered for
systems less than 50kW in size. The first option takes advantage of these incentives by staying
below the 50kW system threshold, and the second option takes advantage of the total usable space

however, if sufficient funding is not available, the Howell High School should at least install the

ECM#24: Replace (5) DX Cooling Condensing Units with 14 SEER High Efficiency Units
A110, A215, C203, C205, C214, C215, and C216 are cooled by split system DX cooling
condensing units, varying from 1-ton to 4-ton models, located on the roof above the associated
building zone. These pieces of equipment were installed in either 1985 or 1992 and are beyond, or
nearing, their expected service lives of 15 years. SWA recommends replacement of the (10)
condensing units to gain increase in operating efficiency. This measure cannot be justified by
energy savings alone, but should be considered as an end-of-life-cycle energy savings opportunity.
The current equipment is operating with a cooling Energy Efficiency Ratio (EER) of approximately
8.0. The new equipment should have a minimum 14.0 EER rating. The higher EER will involve
increased cost for the equipment over units with lower EER. The equipment shall be Energy Star
certified and ASHRAE 90.1 compliant. The equipment shall utilize R-410A refrigerant.

PROPOSED FURTHER RECOMMENDATIONS
Capital Improvements
Capital Improvements are recommendations for the building that may not be cost-effective at the
current time, but that could yield a significant long-term payback. These recommendations should
typically be considered as part of a long-term capital improvement plan. Capital improvements
should be considered if additional funds are made available, or if the installed costs can be shared
with other improvements, such as major building renovations. SWA recommends the following
capital improvements for the Howell High School:
x
Install premium motors when replacements are required - Select NEMA Premium motors when
replacing motors that have reached the end of their useful operating lives.
x
Replace all original, single-glazed windows with a low-E, double glazed type.
x
Replace common area heating equipment - such as finned tube radiation and cabinet unit
heaters in the toilet rooms, vestibules and corridors. This equipment is in fair condition, but age
and wear have reduced the heat transfer capacity. This equipment should be replaced with
more modern equipment suited for the intended use. These changes cannot be justified based
on energy savings alone. However, replacement is strongly recommended along with upgrades
to other portions of the heating system. This is a replacement in kind recommendation which
offers negligible energy savings.
x
Replace and re-commission the Automatic Temperature Controls (ATC) system - There are a
few different systems within Howell High School, as detailed in Section 2.1 Mechanical
Systems, Controls above. In general, the building has fair temperature control, but there are
areas where the ATC system does not function well. SWA recommends that one uniform ATC
system is provided for the school. Since the school has a few separate areas with a Johnson
Controls Metasys system that appears to be in good condition, SWA recommends that the
School removes the ATC systems in the remainder of the school and upgrades and enhances
the existing Johnson systems to provide one, comprehensive ATC system. The three-way
valves at each of the boilers in the original boiler room should be checked and repaired or
replaced to allow the existing water temperature reset control to function properly. In addition,
any equipment not currently interfaced with a current ATC system shall be incorporated into the
new ATC system. The Johnson system is open BACnet protocol. The cost to provide one
Johnson ATC system utilizing as much of the existing system as possible is $1,600,000.
x
Replace unit ventilators - The (39) Nesbitt unit ventilators installed in 1964 and (33) A and C
Wing Trane units were installed in 1979. These units are beyond their expected service life.
Considering the increased maintenance repair costs and that replacement parts are difficult to
find, SWA recommends replacement of this equipment. There is better control offered by the
newer, electronically controlled units, although energy savings are negligible.
o The unit ventilators are operating beyond their useful operating lives. SWA evaluated
replacement of all (72) units with new. The updated fan coils should be double inlet,
forward curved of centrifugal variety; have a maximum speed of 1,000 rpm with
permanent split capacitor motors. The fan housing should be constructed of heavy
gauge metal to help reduce air noise during operation. Wheel motors are to be
premium efficiency, single speed, and permanent split capacitor with overload
protection. Each fan should be equipped with a three speed switch for air balancing.

Freehold RHSD-Howell High School
Page 62/111
o
An ultra-low leak, blade type outside air damper will ensure low leakage of the
outside air when the equipment is not operating. The unit shall have a solid-state
defrost control system and two separate filters. The provided air-to-air heat
exchanger should be designed to support two air streams in a counter-flow direction.
The heat exchanger matrix shall permit less than one percent of cross contamination
between the air streams. The heat exchanger shall have an effectiveness of
approximately 80% with equal airflow. The proposed unit will not be that much more
energy efficient than the existing unit. The estimated budget installed cost of a 72
new fan coil ventilators is $700,000. The recommended enhancements over the
replacement in kind will offer negligible energy savings.
Howell High School may wish to consider adding DX cooling as part of the
equipment replacement. In this case, it should be recognized that cooling will result
in an increase in energy usage versus providing heating and ventilation only. The
estimated budget installed cost for DX coil and air cooled condensing units for the
unit ventilators is an additional $265,000. Note that the addition of air
conditioning may require an upgrade to the existing electric service. The cost
of the electric service upgrade is broken out separately below but should be
included if the cooling option above is incorporated.
x
Replace packaged RTU serving Media Center - The packaged RTU serving the Media Center is
operating beyond its expected service life. SWA recommends that this equipment is replaced
with three units in the 12.5-15 ton range as part of a capital improvement project, and that it is
designed to provide code minimum ventilation rates. It is strongly recommended that systems
are provided that utilize a heat recovery wheel for pretreatment of the outside air and CO2
sensors for demand control ventilation. This is a replacement in kind recommendation that
cannot be justified by energy savings alone. The estimated budget installed cost for (3) rooftop
units with DX cooling and heat recovery wheel, including new ductwork, is $170,000.
x
Replace/provide (4) H&V units to serve the Main Gym B100 and Auxiliary Gym B101 - The hot
water heating only ventilation system for the Main Gym and Auxiliary Gym is beyond its
expected service life. SWA recommends that this equipment is replaced as part of a capital
improvement project, and that it is designed to provide code minimum ventilation rates. The
estimated budget installed cost for (4) hot water H&V units for the Main Gym and Auxiliary Gym
is $195,000. Howell High School may wish to consider providing DX cooling as part of this
system to make the room more functional in warm weather, but should recognize that this will
increase energy usage versus providing a heating and ventilation system only. If cooling is
desired, it is strongly recommended that a system is provided that utilizes a heat recovery wheel
for pretreatment of the outside air and CO2 sensors for demand control ventilation. This is a
replacement in kind recommendation which offers negligible energy savings. The estimated
budget installed cost for (4) rooftop H&V units with DX cooling and heat recovery wheel is
$280,000. Note that the addition of air conditioning may require an upgrade to the
existing electric service. The cost of the electric service upgrade is broken out separately
below but should be included if the cooling option above is incorporated.
x
Replace (2) hot water heating air handling units serving the Auditorium - The hot water air
handling units in the Auditorium are beyond its expected service life. SWA recommends that this
equipment is replaced as part of a capital improvement project, and that it is designed to provide
code minimum ventilation rates. The estimated budget installed cost for (2) hot water air
handling units for the Auditorium is $95,000.

Page 63/111
x
Replace three (3) horizontal pad-mounted end suction pumps in the Original Boiler Room – The
three (3) original hot water heating system pumps are in fair condition. SWA recommends that
this equipment is replaced to minimize future maintenance costs and provide more efficient
operation. This upgrade will provide negligible energy savings. The estimated cost for
demolition and replacement of the three pumps is approximately $65,000.
x
Replace existing elevator in C Wing. This elevator is 40+ years old and is at the end of its
expected service life. Replacement will yield negligible energy savings. The estimated
replacement cost is $60,000.
x
Replace window air conditioners – Several of the existing window air conditioners still have
some useful life remaining (on the average 0-5 years left) but replacement should be considered
with more modern, energy efficient systems. The window air conditioners should be replaced
with split systems to allow for closing up of the existing window or wall penetrations. These
upgrades cannot be justified by energy savings alone but will result in a decrease in energy
usage versus the existing equipment. In addition, some of the existing systems utilize R-22
refrigerant, which is not an ozone-friendly refrigerant. Newer systems should be specified with
R-410A refrigerant.
x
Consider replacement of the 1964 walk-in cooler and freezer with newer models. The wall and
roof panels of the box itself are likely not insulated to the levels of current walk-in coolers. This
is a replacement in kind recommendation which cannot be recommended based on energy
savings alone.
Operations and Maintenance
Operations and Maintenance measures consist of low/no cost measures that are within the
capability of the current building staff to handle. These measures typically require little investment,
and they yield a short payback period. These measures may address equipment settings or staff
operations that, when addressed will reduce energy consumption or costs.
x
Apply appropriate air-sealing strategies around all exterior wall penetrations (including electrical,
plumbing and HVAC).
x
Repair and maintain all gutter to downspout connections.
x
Repair and patch roof leakage areas and remove sharp edged objects from roof surface.
x
Install/replace and maintain sealants at all windows for airtight performance.
x
Air balance distributed conditioned air - for uniform and steady temperature control. This activity
is also included in Retro-commissioning, ECM#14.
x
Thoroughly and evenly insulate space above the ceiling tiles and plug all ceiling penetration. All
missing ceiling tiles should be put back in place.
x
Maintain roofs - SWA recommends regular maintenance to verify water is draining correctly.
Steven Winter Associates, Inc. - LGEA Final Report
Freehold RHSD-Howell High School
Page 64/111
x
Maintain downspouts and cap flashing - Repair/install missing downspouts and cap flashing as
needed to prevent water/moisture infiltration and insulation damage. SWA recommends round
downspout elbows to minimize clogging.
x
Provide weather-stripping/air-sealing - SWA observed that exterior door weather-stripping was
beginning to deteriorate in places. Doors and vestibules should be observed annually for
deficient weather-stripping and replaced as needed. The perimeter of all window frames should
also be regularly inspected, and any missing or deteriorated caulking should be re-caulked to
provide an unbroken seal around the window frames. Any other accessible gaps or penetrations
in the thermal envelope penetrations should also be sealed with caulk or spray foam.
x
Repair/seal wall cracks and penetrations - SWA recommends as part of the maintenance
program installing weep holes, installing proper flashing and correct masonry efflorescence, and
sealing wall cracks and penetrations wherever necessary in order to keep insulation dry and
effective.
x
Provide water-efficient fixtures and controls - Adding controlled on/off timers on all lavatory
faucets is a cost-effective way to reduce domestic hot water demand and save water. Building
staff can also easily install faucet aerators and/or low-flow fixtures to reduce water consumption.
There are many retrofit options, which can be installed now or incorporated as equipment is
replaced. Routine maintenance practices that identify and quickly address water leaks are a
low-cost way to save water and energy. Retrofitting with more efficient water-consumption
fixtures/appliances will reduce energy consumption for water heating, while also decreasing
water/sewer bills.
Older water faucets, no aerators
x
SWA recommends that the building considers purchasing the most energy-efficient equipment,
including ENERGY STAR® labeled appliances, when equipment is installed or replaced. More
information can be found in the “Products” section of the ENERGY STAR® website at:
http://www.energystar.gov.
x
Use smart power electric strips - in conjunction with occupancy sensors to power down
computer equipment when left unattended for extended periods of time.
Steven Winter Associates, Inc. - LGEA Final Report
Freehold RHSD-Howell High School
Page 65/111
Computers left on in Media Center back room after school hours
x
Create an energy educational program - that teaches how to minimize energy use. The U.S.
Department of Energy offers free information for hosting energy efficiency educational programs
and plans. For more information please visit: http://www1.eere.energy.gov/education/.
x
Boilers and building piping insulation - Insulate un-insulated heating piping throughout the
building to efficiently deliver heat where required and provide personnel protection.
x
Water levels in the expansion tanks and the integrity of the tank bladder should be checked on a
regular basis to confirm proper operation.
x
For Aerco condensing boilers, inspect the igniter and flame sensor and calibrate combustion
every six months per manufacturer’s recommendations.
x
Change filters in rooftop units and air handling units monthly to ensure efficient operation of the
fan, ensure adequate air delivery to the space.
x
Tighten belts on exhaust fans and air handling units supply fans every three to six months –
tightening belts on belt-driven fans can maximize overall efficiency of the equipment.
x
Inspect RTU and air handling unit coils for dirt buildup or coil freezeup every three to six
months. These conditions should be rectified if found and they will cause inefficient operation
and possibly damage to the equipment.
x
Inspect condensate pan and drain line on all RTUs and air handling units. Remove sludge or
foreign materials that might obstruct proper drainage.
x
Inspect and replace gasketing around door into walk-in refrigeration boxes. Ineffective gasketing
allows infiltration of warm air into the walk-in box, which increases the run-time of the
compressors.
The recommended ECMs and the list above are cost-effective energy efficiency measures and
building upgrades that will reduce operating expenses for the Freehold RHSD. Based on the
requirements of the LGEA program, the Freehold RHSD must commit to implementing some of
these measures, and must submit paperwork to the Local Government Energy Audit program within
one year of this report’s approval to demonstrate that they have spent, net of other NJCEP
incentives, at least 25% of the cost of the audit (per building). The Howell High School should
spend a minimum of $4,923 (or 25% of $19,692) worth of ECMs, net of other NJCEP incentives, to
fulfill the obligations.

APPENDIX D: GLOSSARY AND METHOD OF CALCULATIONS
Net ECM Cost: The net ECM cost is the cost experienced by the customer, which is typically
the total cost (materials + labor) of installing the measure minus any available incentives. Both
the total cost and the incentive amounts are expressed in the summary for each ECM.
Annual Energy Cost Savings (AECS): This value is determined by the audit firm based on the
calculated energy savings (kWh or Therm) of each ECM and the calculated energy costs of the
building.
Lifetime Energy Cost Savings (LECS): This measure estimates the energy cost savings over
the lifetime of the ECM. It can be a simple estimation based on fixed energy costs. If desired,
this value can factor in an annual increase in energy costs as long as the source is provided.
Simple Payback: This is a simple measure that displays how long the ECM will take to breakeven based on the annual energy and maintenance savings of the measure.
ECM Lifetime: This is included with each ECM so that the owner can see how long the ECM
will be in place and whether or not it will exceed the simple payback period. Additional guidance
for calculating ECM lifetimes can be found below. This value can come from manufacturer’s
rated lifetime or warranty, the ASHRAE rated lifetime, or any other valid source.
Operating Cost Savings (OCS): This calculation is an annual operating savings for the ECM. It
is the difference in the operating, maintenance, and / or equipment replacement costs of the
existing case versus the ECM. In the case where an ECM lifetime will be longer than the
existing measure (such as LED lighting versus fluorescent) the operating savings will factor in
the cost of replacing the units to match the lifetime of the ECM. In this case or in one where
one-time repairs are made, the total replacement / repair sum is averaged over the lifetime of
the ECM.
Return on Investment (ROI): The ROI is expresses the percentage return of the investment
based on the lifetime cost savings of the ECM. This value can be included as an annual or
lifetime value, or both.
Net Present Value (NPV): The NPV calculates the present value of an investment’s future cash
flows based on the time value of money, which is accounted for by a discount rate (assumes
bond rate of 3.2%).
Internal Rate of Return (IRR): The IRR expresses an annual rate that results in a break-even
point for the investment. If the owner is currently experiencing a lower return on their capital
than the IRR, the project is financially advantageous. This measure also allows the owner to
compare ECMs against each other to determine the most appealing choices.
Gas Rate and Electric Rate ($/therm and $/kWh): The gas rate and electric rate used in the
financial analysis is the total annual energy cost divided by the total annual energy usage for the
12 month billing period studied. The graphs of the monthly gas and electric rates reflect the
total monthly energy costs divided by the monthly usage, and display how the average rate
fluctuates throughout the year. The average annual rate is the only rate used in energy savings
calculations.

* The lifetime operating cost savings are all avoided operating, maintenance, and/or component
replacement costs over the lifetime of the ECM. This can be the sum of any annual operating savings,
recurring or bulk (i.e. one-time repairs) maintenance savings, or the savings that comes from avoiding
equipment replacement needed for the existing measure to meet the lifetime of the ECM (e.g. lighting
change outs).
Excel NPV and IRR Calculation
In Excel, function =IRR (values) and =NPV(rate, values) are used to quickly calculate the IRR
and NPV of a series of annual cash flows. The investment cost will typically be a negative cash
flow at year 0 (total cost - incentive) with years 1 through the lifetime receiving a positive cash
flow from the annual energy cost savings and annual maintenance savings. The calculations in
the example below are for an ECM that saves $850 annually in energy and maintenance costs
(over a 10 year lifetime) and takes $5,000 to purchase and install after incentives:

Solar PV ECM Calculation
There are several components to the calculation:
Costs:
Energy Savings:
Incentive 1:
Incentive 2:
Assumptions:
Material of PV system including panels, mounting and net-metering +
Labor
Reduction of kWh electric cost for life of panel, 25 years
NJ Renewable Energy Incentive Program (REIP), for systems of size
50kW or less, $1/Watt incentive subtracted from installation cost
Solar Renewable Energy Credits (SRECs) - Market-rate incentive.
Calculations assume $600/Megawatt hour consumed per year for a
maximum of 15 years; added to annual energy cost savings for a period
of 15 years. (Megawatt hour used is rounded to nearest 1,000 kWh)
A Solar Pathfinder device is used to analyze site shading for the building
and determine maximum amount of full load operation based on available
sunlight. When the Solar Pathfinder device is not implemented, amount
of full load operation based on available sunlight is assumed to be 1,180
hours in New Jersey.
Total lifetime PV energy cost savings =
kWh produced by panel * [$/kWh cost * 25 years + $600/Megawatt hour /1000 * 15 years]
ECM and Equipment Lifetimes
Determining a lifetime for equipment and ECM’s can sometimes be difficult. The following table
contains a list of lifetimes that the NJCEP uses in its commercial and industrial programs. Other
valid sources are also used to determine lifetimes, such as the DOE, ASHRAE, or the
manufacturer’s warranty.
Lighting is typically the most difficult lifetime to calculate because the fixture, ballast, and bulb
can all have different lifetimes. Essentially the ECM analysis will have different operating cost
savings (avoided equipment replacement) depending on which lifetime is used.
When the bulb lifetime is used (rated burn hours / annual burn hours), the operating cost
savings is just reflecting the theoretical cost of replacing the existing case bulb and ballast over
the life of the recommended bulb. Dividing by the bulb lifetime will give an annual operating cost
savings.
When a fixture lifetime is used (e.g. 15 years) the operating cost savings reflects the avoided
bulb and ballast replacement cost of the existing case over 15 years minus the projected bulb
and ballast replacement cost of the proposed case over 15 years. This will give the difference of
the equipment replacement costs between the proposed and existing cases and when divided
by 15 years will give the annual operating cost savings.

APPENDIX F: INCENTIVE PROGRAMS
New Jersey Clean Energy Pay for Performance
The NJ Clean Energy Pay for Performance (P4P) Program relies on a network of Partners who
provide technical services to clients. LGEA participating clients who are not receiving Direct
Energy Efficiency and Conservation Block Grants are eligible for P4P. SWA is an eligible
Partner and can develop an Energy Reduction Plan for each project with a whole-building
traditional energy audit, a financial plan for funding the energy measures and an installation
construction schedule.
The Energy Reduction Plan must define a comprehensive package of measures capable of
reducing a building’s energy consumption by 15+%. P4P incentives are awarded upon the
satisfactory completion of three program milestones: submittal of an Energy Reduction Plan
prepared by an approved Program Partner, installation of the recommended measures and
completion of a Post-Construction Benchmarking Report. Theincentives for electricity and
natural gas savings will be paid based on actual savings, provided that the minimum
15%performance threshold savings has been achieved.
For further information, please see: http://www.njcleanenergy.com/commercialindustrial/programs/pay-performance/existing-buildings .
Direct Install 2010 Program*
Direct Install is a division of the New Jersey Clean Energy Programs’ Smart Start Buildings. It is
a turn-key program for small to mid-sized facilities to aid in upgrading equipment to more
efficient types. It is designed to cut overall energy costs by upgrading lighting, HVAC and other
equipment with energy efficient alternatives. The program pays up to 60% of the retrofit costs,
including equipment cost and installation costs.
Eligibility:
x Existing small and mid-sized commercial and industrial facilities with peak electrical
demand below 200 kW within 12 months of applying
x Must be located in New Jersey
x Must be served by one of the state’s public, regulated or natural gas companies
x Electric: Atlantic City Electric, Jersey Central Power & Light, Orange Rockland
Electric, PSE&G
x Natural Gas: Elizabethtown Gas, New Jersey Natural Gas, PSE&G, South
Jersey Gas

program, go to: http://www.njcleanenergy.com/commercial-industrial/programs/direct-install
Smart Start
New Jersey’s SmartStart Building Program is administered by New Jersey’s Office of Clean
Energy. The program also offers design support for larger projects and technical assistance for
smaller projects. If your project specifications do not fit into anything defined by the program,
there are even incentives available for custom projects.

There are a number of improvement options for commercial, industrial, institutional,
government, and agricultural projects throughout New Jersey. Alternatives are designed to
enhance quality while building in energy efficiency to save money. Project categories included
in this program are New Construction and Additions, Renovations, Remodeling and Equipment
Replacement.
For the most up to date information on how to participate in this program, go to:
http://www.njcleanenergy.com/commercial-industrial/programs/nj-smartstart-buildings/njsmartstart-buildings.
Renewable Energy Incentive Program*
The Renewable Energy Incentive Program (REIP) provides incentives that reduce the upfront
cost of installing renewable energy systems, including solar, wind, and sustainable biomass.
Incentives vary depending upon technology, system size, and building type. Current incentive
levels, participation information, and application forms can be found at the website listed below.
Solar Renewable Energy Credits (SRECs) represent all the clean energy benefits of electricity
generated from a solar energy system. SRECs can be sold or traded separately from the power,
providing owners a source of revenue to help offset the cost of installation. All solar project
owners in New Jersey with electric distribution grid-connected systems are eligible to generate
SRECs. Each time a system generates 1,000 kWh of electricity an SREC is earned and placed
in the customer's account on the web-based SREC tracking system.
For the most up to date information on how to participate in this program, go to:
http://www.njcleanenergy.com/renewable-energy/home/home.
Utility Sponsored Programs
Check with your local utility companies for further opportunities that may be available.
Energy Efficiency and Conservation Block Grant Rebate Program
The Energy Efficiency and Conservation Block Grant (EECBG) Rebate Program provides
supplemental funding up to $20,000 for eligible New Jersey local government entities to lower
the cost of installing energy conservation measures. Funding for the EECBG Rebate Program is
provided through the American Recovery and Reinvestment Act (ARRA).
For the most up to date information on how to participate in this program, go to:
http://njcleanenergy.com/EECBG
Other Federal and State Sponsored Programs
Other federal and state sponsored funding opportunities may be available, including BLOCK
and R&D grant funding. For more information, please check http://www.dsireusa.org/.
*Subject to availability. Incentive program timelines might not be sufficient to meet the 25% in 12 months
spending requirement outlined in the LGEA program.
