Board of Aldermen — State-of-the-City-Address Page 5
February 16, 2016

will meet monthly to discuss specific plans regarding substance abuse prevention, treatment, recovery, and
law enforcement intervention.

Another challenge is state and federal downshifting of costs and responsibilities onto the city and its taxpayers.
The magnitude of this downshifting is beyond what many people realize. Let’s take a single example — the
state run and state mandated pension system for city employees. Over the past several years the State of
New Hampshire downshifted between $10 and $13 million in additional pension costs onto the City of Nashua,
that’s per year. These were costs the state had previously borne in recognition that the system is state
mandated, state controlled and state managed. For the same $10 to $13 million in pension costs that the state
has downshifted onto city taxpayers, the city could have early childhood education for all children, we could
have a program to ensure that third graders can read at grade level, we could have another POP unit in the
police department to help us fight drug related crime, we could have a lot more street paving and we would still
have significantly lower taxes.

We will be watching any future efforts of the state to raise taxes on city taxpayers, and will be sounding the
alarm when this occurs. State officials should no longer be allowed to avoid their responsibilities by quietly
raising property taxes. An issue which will be discussed in 2016 is the potential outside contracting of our
custodial services. During 2015, the Board of Education requested proposals for the privatization of the
custodial services for school buildings. Privatization would put 101 employees out of work. This is a step that |
do not believe is in the long-term best interests of the City of Nashua. Over the past months | have come to
know many of our custodians and understand better the role that they play in our schools. Custodians are
members of each school community. Not only to they maintain our school buildings, the city’s most valuable
physical asset, but they also contribute in many other ways like helping with children and staying late to make
after school activities possible and also in many other ways.

| also want to draw your attention to the importance of infrastructure in our city. At our town halls citizens have
raised the condition of our streets and their transportation needs over and over again. We need to help our
people get from place to place with ease and without obstacle. Over the course of 2016, the Board of
Aldermen, the city and | will be making progress on some significant infrastructure projects. In 2016, | believe
we will be taking a needed leap forward in street paving. The city has fallen way behind in street paving over a
number of years and residents all over the city have been raising this problem for a long time. We must catch
up. We will soon be bringing on line a software system that will enable us to simultaneously evaluate the
condition of all the city’s 1,300 streets. We will then bond for the paving of most of the city’s arterial streets and
a lot of the neighborhood streets during the 2016 and 2017 construction seasons.

Another big project is the improvement of the property the city bought last year at the end of Burke Street. This
is a four acre parcel of land with a massive garage and an attached 50,000 square foot office space. This
purchase accomplished some important objectives. First, the land we bought is adjacent to the city’s sewage
treatment plant which has used up all the land around it so that we will now have the land to make any
necessary expansion. Second, the city needs a new public works garage. Our current garage is more than 40
years old and is not large enough for our needs. The DPW has to keep dump trucks and other vehicles
outside which shortens their life. The Burke Street project will give us the space we need to house all of the
DPW and Parks Department vehicles indoors with room to spare. Third, the dilapidated parks buildings in
Greeley Park need to be replaced and they have for a long time. Instead of spending money to do that we will
move these park functions to the new facility on Burke Street.

Finally, the 50,000 square foot office building is large enough to house all public works and engineering
employees. It is also large enough for our school administration. Moving the school administration to Burke
Street will enable us to use the current school administration building for a program for children with severe
disabilities which will save the city $68,000 per year in rent. It cost the city $4 million to buy the Burke Street
property and the estimate is that it will take another $10 to $15 million dollar investment to improve the facility
for city use. It would cost the city more than $60 million dollars to construct a new facility like the one on Burke
Street so by moving forward on this project we can save tens of millions of dollars. We will be hosting a tour of
the Burke Street facility for the public on a Saturday morning in March and the Board of Aldermen will be part

ENERGY EFFICIENT INVESTMENTS INC.

ECM 6-—- Mini Splits
EEI proposes removing the (19) existing Mitsubishi ductless splits.

Furnish and install (19) new Mitsubishi condensing units of the same capacity of the existing system.
Counts are as follows: (7) 1-ton ceiling cassette systems, (3) 1.5-ton ceiling cassette systems, (1) 2-ton
ceiling cassette system. (1) 1-ton wall mounted system, (6) 1.5-ton wall systems, (1) 2-ton wall
mounted system. New units will be furnished with wind baffles for low ambient cooling and new wall
mounted thermostats.

IPMVP Option B, Retrofit Isolation with All Parameter Measurement, has been chosen for this ECM. This
option has been chosen because the only parameter changing in the implementation of this ECM is the mini
split Energy Efficiency Ratio (EER). EET will use current transducers to measure the EER for a 20% sample
of the mini splits over a one month period to obtain a representative loading profile.

ECM 7—- Condensing Hot Water

The current water heating units are standard efficiency. This measure would be to replace the current
system with high efficiency condensing Lochinvar units.

IPMVP Option A, Retrofit Isolation with Key Parameter Measurement, has been chosen for this ECM. This
option has been chosen because the only parameter changing in the implementation of this ECM is the
combustion efficiency. EEI will use a flue gas analyzer to measure each water heater efficiency before and
after ECM implementation.

ECM 8 -— Targeted Balancing

EEI proposes targeted balancing of the existing ventilation systems. When ventilation units are over -
ventilating it causes unnecessary conditioning of outside air. This measure would include checking the
air flow at the diffusers to ensure that it meets current code required flow.

IPMVP Option A, Retrofit Isolation with Key Parameter Measurement, has been chosen for this ECM. This
option has been chosen because the only parameter changing in the implementation of this ECM is the
airflow amount. EEI will use airflow hoods to measure a 20% sample of diffuser airflow cfm before and after
ECM implementation.

ECM 9- kitchen Hood

The existing kitchen exhaust system has a basic on/off operation. This results in the system operating during
times when it doesn’t need to be operating and heated or cooled air is exhausted. This measure is for
installing a Captive Aire unit with VFD drives on the kitchen hood exhaust fans. A temperature sensor will
be installed in the duct work and control operation based on the temperature inside the duct.

IPMVP Option B, Retrofit Isolation with All Parameter Measurement, has been chosen for this ECM. This
option has been chosen because the only parameter changing in the implementation of this ECM is the
kitchen hood exhaust fan speeds. EEI will use Energy Management System (EMS) trending data over a one
month period to obtain a representative loading profile.

ECM 10- Walk In Coolers

EEI recommends refngeration controllers on walk-in coolers and freezers and installing electronically
commutated (EC) motors on evaporator fans. A controller can start/stop the evaporator fans when operation
is unnecessary. The EC motors are 30% more efficient than the standard two-pole motors. Energy savings
will be realized by reducing the runtime of the compressors and evaporator fans as well as the reduction in
power load of the new fans. Each walk-in cooler or freezer will have a new EC fan motor and blade installed
as well as a dedicated controller. In addition, controllers will be installed on the freezer to optimize the
operation of the electric defroster and door heater. The controller unit senses when refngerant has ceased
flowing through the evaporator coil and controls the fan motors. Door and frame heaters are controlled based
on dew point, reducing their run time by 95% in coolers and 60% in freezers. The controllers will reduce
compressor and evaporator runtime by up to 10%.

Calculations

Energy savings will result from both reducing the fan power and the efficient control of the evaporator fans
and door heaters. In general, EEI uses the following approach to determine savings for this specific measure:

Existing kW Cost per kWh
Cost of Existing Equipment

Cost of Proposed Equipment Energy Savings

Listed Equipment Amperage x Voltage of Equipment Average Site Data Package $/kWh
= Existing kW x Cost per kWh x Effective Full Load Hours

= Existing kW x Cost per kWh x Full Load Hours Using Control

= Existing Equipment Costs- Proposed Equipment Costs

IPMVP Option B, Retrofit Isolation with All Parameter Measurement, has been chosen for this ECM. This
option has been chosen because the only parameters changing in the implementation of this ECM are the
evaporator fan power and run time hours, the condensing unit run time hours, and the door heater run time
hours. EEI will use current transducers to measure each parameter over a one month period to obtain a
representative loading profile.

Nashua South High School

ECM 1- LED Lighting

The schools currently utilize a combination of T8 and TS fluorescent lighting. EEI proposes replacing the
existing fixtures with new LED lighting. EEI performed a detailed survey of the interior and exterior spaces
in order to identify opportunities in which we can improve lighting quality, reduce maintenance costs, and
save energy.

The existing lighting demand (kW) per fixture, hours of operation, fixture quantities, and recommended
retrofits are based on the physical inspection and site visits conducted by EEI in 2018. As a result of the
survey and analysis, EEI has developed a high efficiency lighting upgrade project that will provide the
schools listed with new LED fixtures with controls, resulting in guaranteed annual energy savings and a
reduction in electrical demand.

LED type lighting provides significant illumination, has longer life expectancy, increased savings in electric
consumption, and provides dimming capabilities. Also, by standardizing all fixtures will reduce future
maintenance requirements.

LED fixtures in a school environment have an estimated life of more than 20 years. There is significant
maintenance savings when LED fixtures are used due to their longer lifespan.

All light energy eventually converts to heat. The conversion to LED fixtures will reduce the building’s
lighting energy intensity (kW/sq. ft), therefore impacting the HVAC heating and cooling loads. Converting to
LED lighting will eliminate 3,270 mmBTU waste heat annually. The reduction in lighting waste heat will
increase the HVAC load during heating season, approximately 13,998 therms annually. Conversely, the
HVAC load will decrease in the cooling system, approximately 65,325 kWh annually. The net HVAC utility
impact is an increase in cost of approximately $4,199. This increase in cost has been subtracted from the
energy savings for the ECM.

Install (3,860) LED 2x4 and 2x4 retrofit fixtures with Spacewise control and wireless dimming capability
Install (260) LED high bay fixtures with Spacewise control and wireless dimming capability

Install (642) LED recessed can fixtures

Install (2,947) LED tubes and (1,644) LED drivers

Install (193) LED lamps

Install (47) LED round decorative fixtures

IPMVP Option A, Retrofit Isolation with Key Parameter Measurement, has been chosen for this ECM. This
option has been chosen because the only parameter changing in the implementation of this ECM is the
fixture input wattage. EEI will use current transducers to measure a20% sample of the fixture input wattage
before and after ECM implementation.

ECM 2- Controls Upgrade

EEI proposes installing a complete DDC system as an extension of the existing N4 Enterprise
Supervisor.

Scope of work:

Demo the existing VAV controllers, keeping the existing communication wiring operational for the
existing controllers. Install new BACnet IP DDC controllers, new space sensors, and new discharge air
sensors. Install network controller hardware and software updates as needed.

IPMVP Option C, Utility Data Analysis of Whole Building, has been chosen for this ECM. This option
has been chosen because the wide ranging effects of a controls system on building energy performance
does not lend itself to isolation measurement. EEI has established the building baseline energy usage
using utility data, see “Baseline Development and Performance Period” section. The building energy
usage will continue to be recorded after the ECM implementation and compared to the baseline to
determine savings. The savings guarantee is contingent on several buildmg operations factors described
in the Conditional Savings Guarantee section later in this report.

ECM 3-— Weatherization

EEI completed a detailed building audit and verified suspected air leakage locations and found
opportunity to improve building performance and save energy. Air leakage is caused by pressure
differences subject to variations in wind velocity and HVAC systems. In order to control heating and
cooling loads, and allow the mechanical systems to operate effectively, pressure differences from the
outdoor environment to the door building spaces must be controlled. The best way to do this is by
tightening the building envelope by insulating and air sealing. This will extend the life cycle of the
building by protecting it from the elements and minimizing moisture carried by air which penetrates the
building. Also, insulation and air sealing increases thermal performance of the building and the comfort,
health and safety of the building occupants.

Scope of work:

Inspect exterior doors for deficiencies to the weather stripping and door sweeps. Install new weather
stripping and door sweeps as needed.

IPMVP Option C, Utility Data Analysis of Whole Building, has been chosen for this ECM. This option
has been chosen because the wide ranging effects of weatherization on building energy performance
does not lend itself to isolation measurement. EEI has established the building baseline energy usage
using utility data, see “Baseline Development and Performance Period” section. The building energy
usage will continue to be recorded after the ECM implementation and compared to the baseline to
determine savings. The savings guarantee is contingent on several buildmg operations factors described
in the Conditional Savings Guarantee section later in this report.

ECM 4- Transformers

EEI evaluated the electrical systems of the s chool buildings and determined that the existing
transformers at Nashua South High School are standard efficiency models and are not designed to
handle the loads of modern facilities. The most common efficiency for commercial and industrial
transformers supplying linear loads in the 30-150 kVA range is 95%, as compared to 98% for a high
efficiency model. Further, conventional transformer losses, which are non-linear, increase by 2.7
times when feeding computer loads. Also, if transformers are not properly vented to the exterior, their

heat output adds to the building cooling load.

EEI recommends the replacement of existing efficient transformers in order to improve the energy
efficiency of the electrical distribution systems through the replacement of the transformers with
new high efficiency units. The scope of work for this measure would include:

30 Transformers

(6) 15 kVA
(2) 45 kVA
(2) 75kVA
(8) 112.5 kVA
(3) 150 kVA
(5) 220 kVA
(1) 225 kVA
(2) 300 kVA
(1) 400 kVA

IPMVP Option B, Retrofit Isolation with All Parameter Measurement, has been chosen for this ECM. This
option has been chosen because the only parameters changing in the implementation of this ECM are the
transformer losses. EEI will use current transducers to measure the losses for each transformer over a one
month period to obtain a representative transformer loading profile.

ECM 5- Retro Commissioning

This is an allowance for an engineermg and maintenance team to install, repair, and replace any
damaged existing to remain equipment. Existing AHUs will include software revisions to reduce energy
consumption. Includes 5 years of analytics reports.

IPMVP Option C, Utility Data Analysis of Whole Building, has been chosen for this ECM. This option
has been chosen because the wide ranging effects of Retro Commissioning on building energy
performance does not lend itself to isolation measurement. EEI has established the building baseline
energy usage using utility data, see “Baseline Development and Performance Period” section. The
building energy usage will continue to be recorded after the ECM implementation and compared to the
baseline to determine savings. The savings guarantee is contingent on several building operations
factors described in the Conditional Savings Guarantee section later in this report.

3. RISK & RESPONSIBILITY SUMMARY

Responsibility Description Proposed Approach

Energy Prices Contract energy prices have been set in the M& V plan. These rates are
based onthe current electric and natural gas costs and are escalated
based onthe US Department of Energy.

M&V Costs The M&V costsare fixed for the duration of the contract. EEI accepts
all risks associated with performing the M& V activities as stated herein.
User Participation Lighting and ECMs: The savings for the lighting and ECMs are based

on the continuation of the current operating strategies. This
responsibility is acceptedby the customer after project completion. The
savings from the operation of the EMCs are based on the control
sequences outlined herein. Since these control sequences could be
overridden by the facility operating staff, the customer accepts
responsibility that the ECMs will continue to operate as specified.
Equipment Performance Lighting: EEI is responsible for ensuring the new lamps and ballasts are
as specified and meet the guaranteed energy savings.

ECMs: EE] is responsible for maintaining fan, pump motors, etc. so that
the power draws remain at the baseline level.

HVAC equipment: EEI will ensure the performance of equipment
outlined in project scope and verify performance during
commissioning, The customer is responsible for maintaining all
equipment and providing annual maintenance records to EEI upon
request.

4, EXISTING CONDITIONS DESCRIPTION

Refer to Final IGA report for existing building descriptions and Energy Conservation Measures
chosen to be implemented by the School District. Careful consideration was given to each measure
and its interaction with the overall building performance.

5. OPERATING HOURS

Lighting operating hours are based on 180 school calendar days, from 6am-4pm, with some
allowance for evening programs or sporting events, as well as operating hours during the summer, in
portions of the building, from 7am-3pm. The post-retrofit period operating hours is assumed to be
the same as the baseline period. Should the customer change the operating hours, the estimated
savings will not change, and baseline updates will need to be made.

Operating hours for other equipment such as boiler, fans, pumps, etc. are based on the baseline
calculations and in the case of a substantial change in schedule, EEI should be notified by the
customer so that baseline adjustments can be made.

Heating set-point will be no higher than 68°F and cooling set-pomt no lower than 72°F. EEI has
estimated the load on the facility based on historical data. The customer is responsible for
maintaining similar operating hours and load conditions in the post-installation period. If operating
hours or load increases, the estimated savings will not change, and baseline updates will need to be
made.
