EXECUTIVE SUMMARY
ISSUE
Staff recently received a completed Feasibility Survey from Johnson Controls that reviewed many of the
City's facilities for energy and infrastructure efficiencies. The survey identified a number of possible
improvements that if made could help reduce operating costs. Staff are continuing to review the data in
the Feasibility Survey with Johnson Controls.
Some of the benefits of the possible improvements include: maintaining an aging facility infrastructure,
improving the energy efficiency of buildings, reduce maintenance requirements and time through the
implementation of updated technologies, having environmentally friendly operations and reducing our
carbon footprint for facility operations. Some additional advantages of a program like this are that it may
free up capital funds for other needs, it is a comprehensive approach to improvements rather than a
piecemeal approach, no up front fees are required, a performance based contractor is tied to providing
savings over the term of the contract and the performance of the improvements is a risk the contractor
takes on.
Some concerns staff has with the proposed recommendations include: some of the facilities identified in
the report might not be included in the City's operations for the next 15 years. The future use of portions
of the former St. Joseph's Campus has not been determined. Some facility improvements might not meet
the operational needs of the facility operators or customers, for example, treating the Ice Arena water for
hardness has been previously been and softer water took too long to freeze resulting in a negative impact
on operations.
BACKGROUND
Staff from the Parks and Recreation, Public Works and Community Development Departments recently
met with a representative from Johnson Controls regarding a program to help facilities operate in a more
efficient manner. Some of the key goals of the program include maintaining an aging facility
infrastructure, improving the energy efficiency of buildings, identifying opportunities to reduce
maintenance requirements and time through the implementation of updated technologies, having
environmentally friendly operations and reducing our carbon footprint for facility operations. Johnson
Controls works with cities like Rosemount through enabling legislation (MN Statute 471.345) to make
improvements to facilities to reduce the cost of operations and then pays for the improvements with the
cost savings. The payback for the projects can be financed through Johnson Controls for up to 15 years
and the performance of the improvements and the cost savings are guaranteed.
In June of 2008, the City Council directed staff to enter into a Memo of Understanding where they will
conduct a no cost feasibility survey. The survey will identify potential opportunities for the City to pursue
and also allow Johnson Controls to see if there are needed improvements that make the projects worth
their time and effort.
Once the feasibility survey is completed, the City could then consider entering into a Project Development
Agreement, which is the detailed analysis of facilities that includes the recommended improvements and
what the cost savings would be. This phase would take between 90 and 120 days to complete and would
include having contractors and other facility professionals inspect all facilities for projected costs and
estimated savings. If the City does not want to implement the recommended projects, where the
operational cost savings will cover the costs of the improvements, the City will be billed for the work
performed by Johnson Controls. If we do choose to move forward with the improvements, the costs
incurred while working on the detailed analysis would be rolled into the costs of the improvements and
paid for through the energy savings.
Other cities who have worked with Johnson Controls on facility efficiency projects include Rochester,
Northfield and Duluth.
The final phase of the process would be to implement the recommended improvements.

I. Executive Summary
Johnson Controls is pleased to present the City of Rosemount the results of our
preliminary survey to determine the feasibility of implementing projects through a
performance -based contract. The authorization of the preliminary survey demonstrated
the City's interest in taking a proactive and cost conscience approach to infrastructure
improvements. The Preliminary Assessment and Business Case Analysis identify areas of
concern, overall project objectives and the future vs. current financial merits of the total
program. With the assistance of key City personnel, the initial assessment of the City of
Rosemount's infrastructure has been completed.
Johnson Controls' preliminary analysis indicates that an infrastructure improvement
program will generate estimated energy and operational savings of $192,000 annually.
Energy efficiency upgrades could reduce energy costs by $162,000 annually. By
implementing the improvements outlined in this report, the City of Rosemount could
realize operational savings and avoided maintenance costs of $10,000 to $15,000
annually. Future capital dollars can also be avoided if the budgeted cost of capital
projects can be offset by energy and operational savings. These dollars, when combined
together, will create a pool of money that can be reallocated to cover the project costs.
Typically, performance contracts are financed as operating leases that are set up on
annual or semi annual payments. Current legislation allows for a maximum 20 year
term. The estimated savings identified in this project would fund approximately
$2,500,000 in improvements over a 15 year term
The efficiencies identified by Johnson Controls will assist in funding the capital projects
outlined in this report. Based on our preliminary calculations, we strongly believe that
we can address these areas and help fund them with the potential savings described
above. By bundling these projects together, the shorter payback items will help pay for
the longer payback projects. We will also guarantee that the energy savings will be
achieved throughout the contract term.
We believe we can offer the City of Rosemount a financially- compelling method that
reduces energy costs, addresses deferred maintenance concerns and completes
budgeted capital projects without negatively impacting the budget. During the detailed
audit, Johnson Controls will verify these findings and finalize costs for the various
solutions.

II. Performance Contracting Process
Johnson Controls recommends that the City of Rosemount considers utilizing a
performance -based contract for implementing infrastructure improvement measures to
reduce energy consumption and operating costs. As its name implies, Performance
Contracting is a performance- based, turnkey approach to implementing facility
improvement projects that generate savings from energy and operational costs.
Performance contracting eliminates risk in two ways. First, Johnson Controls establishes
the installation price for the entire project when the contract is signed. This will
eliminate the common practice of change orders on construction -type projects. Second,
Johnson Controls guarantees that the projected savings will occur. If the guaranteed
savings are not realized, Johnson Controls will reimburse the City of Rosemount the
difference. This process ensures that there will be a revenue stream to cover the cost of
the projects.
Preliminary Analysis
The performance contracting process began with the preliminary investigation and
analysis of the City of Rosemount's infrastructure with regards to its energy usage, its
operational and maintenance budgets, and its planned capital improvements. The
purpose of the preliminary study is to determine the viability of utilizing performance
based contracting to address concerns and to improve operating efficiencies. Based on
our preliminary findings, Johnson Controls is confident that we can work with the City to
reduce energy use and maintenance costs through infrastructure improvements. We
are eager to move forward to the project development phase.
To move forward, the City of Rosemount and Johnson Controls will enter a Project
Development Agreement (PDA) that outlines the scope of the detailed development
that Johnson Controls will undertake. The PDA defines the roles and responsibilities of
the City and Johnson Controls as we cooperatively develop our project.
Project Development Customer Commitment
A detailed analysis of each facility improvement measure establishes an accurate
assessment of the projected budget revenue and expense impact. This aspect of our
investigation is extremely detailed in order to provide customized solutions for the City
and optimize the level of performance guarantee Johnson Controls can provide. Our
unique Business Case Analysis provides a financial model that helps you select the best
combination of improvements for your needs. Johnson Controls will perform a detailed
investigation of electricity and gas usage; facility lighting; HVAC; controls; building
envelopes; and any other areas where our engineers feel they can improve energy
efficiency and reduce operating costs.

Controls
The cost of the Project Development phase will be presented to you in the PDA before
we proceed with project development. The financial model will include this cost in the
payment stream. The City will be obligated to pay the cost only if Johnson Controls
develops a self- funding project but the City of Rosemount decides not to proceed to a
performance contract.
Contract Approval Project Implementation
After the Project Development is complete, a final agreement is generated and signed
with a scope of the work, timeframes, savings calculations, financial model, guarantee
methods, and any ongoing services, requested by the City of Rosemount. The
installation will be completed in a timely manner to realize cost savings and generate
additional revenues as soon as possible.
Performance Assurance
As identified in legislation, Johnson Controls will financially guarantee the projects it
implements; therefore, it is important for us to work closely with the City of Rosemount
for the duration of the contract. The contract includes services required to ensure that
the guarantee is met. Through our results- oriented services, we are able to track the
functions of your facilities and work to maintain the most efficient operations while
maintaining and /or improving your level of comfort.

I11. Facility Infrastructure Overview
Johnson Controls' professionals have toured the City of Rosemount's facilities and have
discussed building operational challenges and goals with City personnel. Johnson
Controls has made a concerted effort to recommend improvements that will provide
substantial value and reduce energy use in City of Rosemount facilities.
The beginning of this section includes our observations of the facilities we visited and
the existing operations. Beginning on Page 16, we identify potential opportunities.
the City of Rosemount City Hall houses many of the city's administrative functions
including the Police Department. Two variable volume air handling units heat and cool
the building's upper floor. One constant volume air handling unit conditions the police
station on the lower level. A fourth unit provides ventilation for the Police Department
garage. The HVAC system is controlled by a Staefa Talon direct digital control (DDC)
system. Hydronic boilers in an adjacent Public Works building operate year round to
provide hot water for reheat coils in
the City Hall. Appropriate control
strategies can minimize the amount
of reheat required in summer
months and reduce energy
consumption. An emergency
generator in the garage provides
back -up electricity for the building.
During the walk through, building
occupants and maintenance
personnel stated that several rooms
have temperature control issues.

The Rosemount Community Center houses the City's Parks Department and Ice Arena.
A banquet room and associated kitchen can be rented out for special occasions. The
city shares the building with the Minnesota National Guard. Shared spaces include a
gymnasium, a theater auditorium and classrooms.
The main building is heated by two
boilers. These boilers run year
round providing humidity control in
the Ice Arena during summer
months. An air cooled chiller
provides comfort cooling. Air
handlers located throughout the
building provide ventilation. The
HVAC system is controlled by a

occupied hours. A DDC system can also coordinate operation of the HVAC system.
Currently, the two air handling units in the gymnasium often work at cross purposes
one is heating while the other is cooling. This makes it difficult to maintain comfort and
uses more energy than a coordinated system.
The Ice Arena operates for the
majority of the year; ice is
removed for five or six weeks
in the late spring for annual
maintenance. The building
operator stated that the city's
ice temperature is set at 16 or
17 °F, whereas most rinks
maintain 19 or 20 °F. He stated
that this is likely due to the
hardness of the water.
Reducing the water hardness
may result in allowing a higher
reduced energy consumption. An ice making machine
h four compressors produces ice for the rink. The compressors are at the end of
their lives and are scheduled to be replaced over the next
four years. New higher efficiency compressors can reduce
maintenance costs and energy consumption.
Infrared heat over the stands in the ice arena provides
heating in the winter. The infrared heat is also run during
the summer to control humidity. Alternate means of
humidity control can reduce energy use during summer
months.

The St. Joseph's Church was built in 1924 and a school was added in 1953. The church is
not heavily used but the school is still active. The City of Rosemount is scheduled to
take possession of these buildings in the fall of 2009.
The two buildings are heated by boilers in the church's basement. The church has
baseboard radiant heat. The school uses unit ventilators with hydronic coils for heat.
Neither building has mechanical cooling. The boilers and heating distribution systems
are near the end of their lives. New, energy efficient boilers and pumping systems can
reduce maintenance costs and energy consumption.
The building envelope shows significant
deterioration, with gaps around doors and
windows and some cracks in building walls.
These opening allow unconditioned air into the

The City of Rosemount Fire Station #1 was built in 1986 and Fire Station #2 was built in
2006. Both stations contain offices, a lounge and kitchen, a workout room, a dispatch
room and a garage. Three rooftop units provide heating and cooling for the main part
of the building. The units at Fire Station #2 have energy saver switches installed to
reduce energy consumption during summer months.
During the walk through, city personnel stated that some of the thermostats in Fire
Station #1 are misplaced. The
thermostat that controls the
break room is in the workout
room and the thermostat that
controls the Fire Chief's corner
office is in an office two doors
down. Therefore, the
temperature of more heavily
occupied rooms is controlled
by more lightly occupied
rooms. This creates
uncomfortable conditions in
the heavily occupied rooms
and can result in higher energy use. Some of the thermostats are the
type and some can be programmed. However, since the buildings are not occupied on a
set schedule, the programmable thermostats are set to a fixed temperature, negating
potential energy savings. A control system that is more adaptable to varied occupancy
can maintain comfortable space conditions and reduce energy consumption.

Several park shelters are located throughout the city. Most park shelters are used
sporadically during the summer but are open every day during the winter for use as
warming houses. Park shelters are heated with gas -fired forced air furnaces, which
circulate heated air through the building. Unfortunately, when a door opens, some of
this heated air is displaced by cold outdoor air. Infrared heat can instead heat surfaces
including people inside the building. When a door opens, less heat escapes and
energy use is reduced. Some park shelters have fixed set point thermostats and others
have programmable thermostats. However, the buildings are not occupied on set
schedules. A control system with flexible scheduling options can reduce energy use.
The Central Park shelter also has air conditioning which can benefit from a control

Six active well houses and five sewage and storm lift stations are located throughout the
city. Well house pumps use variable frequency drives for soft start and to flow
modulation. A supervisory control and data acquisition system (SCADA) communicates
wirelessly and over telephone lines for monitoring and control. The state of the art in
SCADA systems is wireless communication; repair parts for telephone line
communication are becoming difficult and expensive to find. Upgrading all systems to
wireless communication can preclude a costly upgrade if the old system fails at a critical
time.

Building Automation System
Direct digital control (DDC) building
automation systems offer a variety of
improvements over pneumatic controls
systems and stand -alone thermostats.
Pneumatic systems require an air
compressor to charge the lines and
make up for inevitable air leaks. After
they are put online, pneumatic systems
are difficult to customize because
changing one part of the system can
have unintended affects on other parts
of the system. Similarly, pneumatic systems are
notoriously difficult to troubleshoot and customize for
varied operation. Pneumatic systems typically have
single set point thermostats. Once set, these
thermostats maintain a constant space temperature
regardless of building occupancy. Therefore, when the
building is not occupied, it is heated or cooled
unnecessarily. To modify set
points, operators must
manually adjust the
thermostat setting. Stand-
alone thermostats, often
equipped with programmable set points that set back
temperatures during unoccupied hours, suffer from lack of
coordination between HVAC equipment. This can be
particularly pronounced in large buildings with a complex mix of equipment. Neither
pneumatic control systems nor stand -alone thermostats allow operators to easily
monitor the big picture of whole building performance. Johnson Controls' automation
systems utilize an "open" protocol which allows for the
integration of different manufacturers.
DDC systems, on the other hand, do not require an air
compressor, lowering energy required to simply
operate the system compared to pneumatic systems.
DDC systems are also easy to customize, adding
flexibility for the customer. DDC systems can be
programmed with a virtually unlimited number of set
points and schedules, so they can accommodate the varied occupancy of many spaces.
Using a customizable front end with a graphical user interface, operators can easily
adjust set points and can monitor the performance of the entire system.
Troubleshooting efforts are enhanced and operations costs reduced as operators can

alarm functions, operators can quickly determine when spaces are out of set point and
can make adjustments, increasing occupant comfort.
Johnson Controls will program systems to optimize energy use while maintaining
personnel comfort. Examples of control strategies that we implement include:
Resetting temperature set points when buildings are unoccupied.
Dynamically optimizing morning start-up times so buildings are comfortable
when occupants arrive.
Demand controlled ventilation for
spaces with widely varying Toads. This
strategy lowers the ventilation rate
when the space is lightly occupied and
increases the ventilation rate when
the space is more heavily occupied,
maintaining indoor air quality.
Incrementally adjusting temperature
set points, air flow rates, and water flow rates to use the least amount of
energy required to maintain comfortable space conditions.
An override feature to switch the system to occupied operation if someone
comes in during unoccupied hours.

the system.

Lighting Upgrades and Occupancy Sensors
Newer fluorescent lighting technologies offer up to a 40 percent
energy savings over older technologies while maintaining light
output levels. Similarly, compact fluorescent bulbs offer a similar
light output with significantly lower energy use and longer life
expectancies than incandescent bulbs. High bay and garage areas
often have probe -start metal halide Tight fixtures. Pulse -start metal
halide or high output
fluorescent lamps present a
suitable retrofit because they consume Tess
energy, have longer life expectancies, and
provide higher Tight outputs. This allows
installation of fewer fixtures.
Although lights are often turned off when buildings are unoccupied, if lights are
manually controlled, they tend to be turned on and left on throughout the day during
normal working hours, even when portions of the building are unoccupied. Lighting
occupancy sensors can turn lights off when not required and automatically turn them on
when people enter the room. Reduced lighting operating hours will result in lower
energy consumption and reduced maintenance costs from longer bulb life.
Johnson Controls recommends replacing
existing fluorescent lighting with more
efficient T8 lighting and replacing
incandescent bulbs with compact
fluorescent bulbs. Johnson Controls will
evaluate areas with metal halide fixtures to determine an
appropriate lighting retrofit. Johnson Controls also
recommends installing occupancy sensors in areas with variable occupancy such as
hallways, rest rooms, and conference rooms to control lighting operation. Johnson
Controls also recommends replacing parking lot lights with more efficient fixtures and
bulbs.

Building Envelope Improvements
Air leakage represents a substantial source of heat Toss or gain through the building
envelope. Unintentional building interior air flows due to pressure differences can also
result in energy loss. Beyond the potential for energy
savings, uncontrolled air flows can affect the comfort
of occupants; indoor air quality due to air flow not
accounted for in the HVAC system design; and the
structural integrity of the building envelope through
moisture migration.
Another source of energy loss in building envelopes is
windows with low heat transfer resistance. Typically
consisting of a single
pane of glass, these
windows allow a large
amount of heat to
escape the building and often permit a large amount of
solar heat gain during summer months. Condensation or
ice buildup on window surfaces suggests this type of
window installation. Newer windows have higher heat
transfer resistance characteristics and block more
incoming solar thermal energy, resulting in lower
building energy consumption.
By sealing gaps, cracks and holes in building envelopes, including weather
stripping around doors and windows, the air tightness of the City's
facilities would increase. Compartmentalizing the heating and cooling
zones in selected buildings will limit inter -zone air flow and moisture
migration as well. Replacing windows where appropriate will reduce
heat loss and solar thermal gain.

The lower levels of the City Hall and the Community Center have air handling systems
that provide a constant flow of
conditioned air. These constant
volume units do not accommodate
changing heating and cooling loads
throughout the day as people come
and go in conditioned spaces.
An opportunity exists to convert
constant volume air handling units
to variable volume at the City Hall
and Community Center. Variable-
volume units lower air flow and
reduce energy consumption when
spaces are lightly loaded and
increase air flow to meet space
needs when they are more heavily
loaded. Lower air flows in the
summer months can reduce or
eliminate the need for operating
boilers for dehumidification.
St. Joseph's Church does not have a
ventilation system and the system at the school is near the end of its useful life. Current
ventilation codes require
introduction of outside air to
maintain indoor air quality for
building occupants. Except for the
preschool addition, neither the
church nor the school has means of
cooling. For future occupancy,
cooling will be essential to keep
occupants comfortable.
If these buildings are to be used
regularly, it is recommended to
St. Joseph's church and school. To maintain
occupant comfort, these systems can include cooling capabilities. These units will bring
in outdoor air which will increase the quality of indoor air and can offset cooling and
heating during shoulder seasons.

Park shelters are used in the winter as warming houses for the outdoor ice rinks. As
people come and go in the buildings, the air heated by the furnaces is displaced by cold
outdoor air, increasing energy use.
Installing infrared heat in the park shelters can reduce energy costs. Infrared heat
warms internal surfaces, including people, rather than the air. Therefore, when doors
are opened, Tess heat escapes the building. The nature of infrared heat allows people to
remain warm with lower temperature set points.

run as efficiently as new compressors
and they have high maintenance costs.

The infrared heaters in the Ice Arena operate throughout
the summer to dehumidify the space, even when the arena
is unoccupied. Installing a system designed specifically for
dehumidification will reduce space humidity more efficiently
and eliminate the need to operate heaters when the arena
is unoccupied. A dedicated dehumidification unit will also
reduce humidity more evenly, decreasing spots of
condensation and increasing comfort.
The City's ice making system produces ice at 16 or 17 °F,
whereas most rinks can make ice at 19 or 20 °F. These lower
ice temperatures are due to water quality issues. An
opportunity exists to evaluate new technology, which is
proven to maintain ice quality at higher temperatures, thus
By replacing the old compressors with more efficient ones, the City will use less energy
and maintenance costs will decrease.

Premium Efficiency Motors
Motors that do not meet NEMA premium efficiency standards consume more energy
than those that meet the standards. For
motors with a large number of annual
operating hours, this excess consumption can
become significant, particularly as motor size
increases. When a motor fails, it is often
repaired by rewinding the electric coils rather
than replacing the motor. While this often
makes economic sense, each rewinding
reduces the motor's efficiency.
By replacing standard efficiency motors with
new motors, the City will reduce energy and
maintenance costs.

Boiler Replacement /Upgrade- St. Joseph's Church and School
Steam boilers have a typical life span of 35 years. Older boilers are less efficient than
new boilers because of component and insulation degradation and technology
advances. Typically, steam boilers have higher
operating costs than hydronic boilers because they
require precise chemistry control. Water must be
made up from periodic blow downs and to adjust
for small Teaks in the system, chemicals must be
added often to maintain water chemistry. Stem
boilers also require more energy input than
hydronic boilers because of their higher operating
temperatures. For buildings that heat with a
hydronic loop through a steam -to -hot water heat
exchanger, energy is lost in the conversion.
Further, hydronic boilers tend to have better turn-
down characteristics, which allow them to maintain higher efficiencies at low heating
loads than steam boilers. For these reasons, replacing steam boilers with hydronic
boilers offers significant energy and operational savings. However, retrofitting steam
boilers with hydronic boilers can require extensive piping and heating coil replacement,
which can be cost prohibitive.
One recommendation is to replace the existing boilers with high efficiency hydronic
boilers. Piping and heating coils would need to be replaced where required to provide
adequate heating. If installing hydronic boilers and piping is cost prohibitive, another
option is to install new high efficiency steam boilers. New boilers whether steam or
hydronic, provide higher efficiencies and reduced operating and maintenance costs.

Even well calibrated and otherwise functional systems do not always maintain space
conditions throughout the wide range of building occupancy patterns and outdoor

occupants providing feedback to system operators and then the operators manually
adjusting set points and system operation to satisfy the occupants. During normal use,
HVAC components can fail or their performance can degrade. These problems are
typically discovered only when the failures cause space conditions to become
uncomfortable and occupants complain or if a maintenance person happens to discover
the failure during normal maintenance activities.

Water Conservation
Water costs are rising dramatically as electric
costs increase, communities grow, and water
sources are strained. Most toilets and urinals
use more water than necessary when flushing.
Sometimes toilets and urinals are not flushed
because people are reluctant to touch items in
public toilets. This can create unclean and
unsanitary conditions in restrooms. Simple
retrofits of flush valve components can reduce
water flow by up to 30 percent while ensuring
the bowls are evacuated.

The internal wear components of urinal
and toilet flush valves should be
retrofitted to reduce water consumption
and increase component life. The new
components are designed and tested to
resist the rigors of substantial use as well
as the effects of chloramines and
sediments in water. Low -flow aerators
should be installed on sinks and faucets to
reduce water consumption. Reduced sink
water flow will also reduce the load on the
domestic hot water system. Automatic

Utility Rate Analysis and Rebates
Utilities offer a broad range of rate structures to
accommodate the varying operations of their customers.
Some rates can provide for lower costs, with customers
shouldering some risk. Other rates are more conservative
but tend to have higher overall costs. Usually, a utility offers
a specific customer an appropriate rate based on their
operation. However, as rate structures or customer
operations change, rates are sometimes not updated to
provide the best value to the customer.
Utilities also often offer rebates for new energy efficient
equipment. Some rebates are as simple as filling out a form
with equipment data entered in. However, complex
installations require a more intensive application process,
often with pre approval requirements. Rebates are offered
for a variety of upgrades, including premium efficiency
motors, building automation systems, high efficiency boilers, and
lighting, to name just a few. When rebates are applied to the project's financial model,
they often justify specifying higher efficiency equipment than with no rebate.
Utility rate programs should be investigated to optimize the City of Rosemount's utility
value. Utility rebates should be customized to provide the highest value and reduce
overall project costs. Our relationship with many of the utilities in the state helps ease
the rebate process and utilities are often eager to work with us to maximize their
customers' rebate potential. Once the rebates are approved, the utility will submit
them directly to the City of Rosemount.

Emergency Backup Generators
Emergency backup electrical generators provide power when service from the utility is
lost. Ideally, a generator is sized to carry all of the building's electric loads, but
sometimes constraints necessitate sizing it to provide only critical loads. Emergency
generators are set up to sense incoming
power. When power is lost, the generator
starts and a transfer switch automatically
brings it online to provide emergency
power. When utility power is restored, the
system either automatically switches back
to normal configuration or the process can
be performed manually.
Approximately half of the city's well houses
and none of the sewage and storm water
lift stations have emergency generators. When utility power is lost, the city must install
temporary generators at the well houses to maintain water supply. Power outages can
also cause lift stations to overflow, which can result in
unsanitary conditions and an expensive clean up.
Backup generators installed at well houses and lift stations
will reduce operating costs associated with temporary
generators and will allow continuity of service in a utility
outage.
Generators can also provide for electric peak shaving.
Electric utilities offer reduced rates to customers who
agree to reduce their electric demand during periods of
heavy loading on the electric grid, often during typically
hot summer days.
Facilities should be evaluated for the feasibility of installing generators for peak shaving
or interruptible electric rate operation. Rather than shed lighting and cooling loads
which can impact productivity, an electric generator supplies power to the building in
parallel with the utility.

Water Meter Calibration
Water Toss is estimated at 10 -20% in distribution
systems throughout the United States. Water loss
can be real or apparent. Real water loss which is
losses due to broken pipes or open connections
can be corrected by detecting and correcting Teaks
in the water distribution system. Apparent water
loss which is when the billed water does not
match the water through the system is often a
result of inaccuracies at the meter. Meters can be
inaccurate if the meter size and type does not
match the usage. Meter inaccuracy can also be
the result of the meter going out of calibration.
With the city's automated meter reading system
and leak detection equipment, Johnson Controls
can detect Teaks in the water distribution system
and track down incorrectly reading meters. By
calibrating water meters for large water users, the
City may see water revenues increase due to
more accurate meter reads.

Renewable and Sustainable Opportunities
Solar PV and Thermal
Photovoltaic (PV) arrays can produce electricity to offset energy use from the utility.
Since peak electricity use and peak electric rates tend to occur during the sunny summer
months, PV arrays can often provide peak shaving capabilities.
Likewise, solar thermal arrays can provide heat
input to the domestic hot water system, offsetting
gas or electric use for water heating. Solar thermal
systems provide heat input even during winter
months, providing year -round energy savings. A
solar thermal system augments a conventional
domestic hot water heater and reduces its required
capacity, lowering replacement costs of the
conventional heater. Due to constraints on domestic hot water storage, solar thermal
systems are best suited for facilities with nearly constant loading, such as large office
buildings, apartments, and detention centers.
Johnson Controls proposes to investigate the feasibility of installing PV or solar thermal
arrays on selected buildings.
Wind Power
Wind turbines tie into current building power supplies and utility systems. When wind
power is available, the turbine provides electric power to the building; when wind
power is not available, the current electric system provides power as it does now. If
wind produces more power than the building needs, the excess power can be sent back
to the electric grid for additional savings in the form of revenue. The availability of
grants, incentives or rebates may help offset the cost of a wind turbine installation

V. Operational Cost Reductions
We were also able to identify potential
opportunities that will avoid operating expenses
for the City of Rosemount. These opportunities
were identified through statistical data, a survey of
the City of Rosemount's operations, review of the
City's Capital Plan and discussions with building
personnel. Based on this information, Johnson
Controls estimates that the City could save $10,000
$15,000 annually in operational savings through
improved maintenance management and reduced
repair expenses. Based on information shared
from the City's Tong -range capital plan, it appears
the City can impact at least $20,000 in avoided
capital costs.
Johnson t
Controls
The following facility improvement measures have the potential to generate operational
savings in repair, maintenance, labor and /or capital budgets:
1. By upgrading old HVAC equipment to new, high- efficiency technology, repairs will be
reduced, operations will be improved, and future costs will be avoided.
Maintenance personnel will be able to operate their facilities in a proactive manner
rather than reacting to day -to -day emergencies.
2. Facility and exterior lighting efficiency can be improved by standardization on more
efficient lighting systems. Operations and maintenance costs will be substantially
reduced due to the extended life expectancy of the new lighting system.
3. The lack of controls on major HVAC equipment can generate substantial operational
savings. When a building is not fully controlled, equipment life is reduced,
maintenance personnel need extra time to troubleshoot and react, and there can be
occupancy and productivity issues.
4. By adding new or modifying existing generator use, the City will be able to maintain
constant power. Operational costs will be reduced through the elimination of the
need to install emergency generators at well houses and lift stations.
5. By recommissioning existing systems and utilizing Facility Performance Indexing, the
City will improve overall operations, eliminate maintenance calls, and create an
environment that enhances employee productivity.

VIII. Conclusion and Recommendations
Johnson Controls has identified a number of potential infrastructure improvements that
can lower energy and operational costs. With an estimated annual savings of $192,000
annually over 15 years, the City of Rosemount can fund approximately $2,500,000 in
improvements.
Johnson Controls is confident that the City of Rosemount can utilize performance
contracting as a tool to implement beneficial infrastructure upgrades. We recommend
that the City enter into a Project Development Agreement with Johnson Controls in
order to identify which projects will be cost effective. The fully developed project will
be presented to the City Council approximately 120 days after beginning the detailed
development. The cost of the PDA is $45,000. As described earlier, this cost will be
covered by the savings generated from the project if the City of Rosemount chooses to
proceed with a performance contract. If Johnson Controls cannot meet the criteria
established in the PDA, the City has no obligation to pay for the PDA. If Johnson

with a Performance Contract, the City will be invoiced for the PDA cost.
We look forward to exceeding your expectations!
