Energy Efficient Facilities Program - Johnson ControlsAGENDA ITEM: Energy Efficient Facilities Program Johnson Controls AGENDA SECTION: Updates PREPARED BY: Dan Schultz, Director of Parks and Recreation AGENDA NO. 3 e ATTACHMENTS: Preliminary Assessment Energy and Infrastructure APPROVED BY: Dl,U RECOMMENDED ACTION: None, update only 4 ROSEMOUNT CITY COUNCIL City Council Special Work Session: January 14, 2009 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. 2 Preliminary Assessment Energy Infrastructure Improvement Project Prepared for The City of Rosemount October 28, 2008 Submitted By: Johnson Controls Madonna Rykken Clayton Dumcum 2605 Fernbrook Lane North Plymouth, MN 55447 763 566 -7650 www.johnsoncontrols.com ROSEMO MINNESOTA Johnson r VIA Controls 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. 1 Johnson 010 Controls 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. 2 ROSEMOUNT J ohnson 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. 3 City Hall Johnson t Controls 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. 4 fCROSEMOLINT. MINNESOTA Some issues identified include: the Police Department patrol room has a non functional cooling unit, the records room has difficulty maintaining conditions, cold air migrates from a return grille in Room 219, and Room 215 has an exterior door that produces a draft when it is opened, allowing unconditioned air to enter the space. These items create uncomfortable working conditions and increase energy use Johnson 040 Controls Some of the lights in the building and the parking Tots use an older technology that consumes more energy for a given light level than newer technologies. Building personnel stated that some areas may also be over -lit. 5 ROSEMOUNT Community Center and Arena Johnson Controls 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 pneumatic control system. A DDC system can allow for optimizing energy use based on building occupancy ventilation can be reduced in areas that are lightly occupied and set points can be modified in office areas during ROSEMOLIN'T MINNESOTA, 66 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. ice temperature and thereby The Community Center incurs a power factor penalty from XceI Energy® due to low power factor. A capacitor bank wr,s installed but has not corrected the power factor above the penalty threshold. An appropriately sized and placed capacitor bank can correct power factor and eliminate the penalty. Johnson i Controls Some of the lights in the building and parking Tots use an older technology that consumes more energy for a given Tight level than newer technologies. 7 ROSEMOLINT Public Works Johnson gi Controls The City's Public Works offices and garages are located near the City Hall. The offices are heated by a furnace with a fixed -set point thermostat. The garages are heated with gas -fired infrared heaters. rinks would reduce fuel costs rinks. Most employees work from 7:00 am to 3:30 pm, but the garage is open seven days a week during the summer for flower watering operation. An automated watering system could help reduce fuel and water costs. The buildings are also open for night operations during the winter to flood outdoor hockey and skating rinks throughout the city. Water connections at some or all of the of transporting water from the Public Works garage to the Lights in the Public Works buildings are generally energy efficient and several are controlled with occupancy sensors. Parking lot lights are controlled by timers, which if not periodically adjusted can result in lights operating while it is still light out. A photo sensor control can help reduce this risk and conserve energy. 8 ROSEM@UNT MINNESOTA Saint Joseph's Church and School Johnson '1 ,��i Controls 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 building, creating discomfort and increasing energy consumption. Most of the lights in the buildings and parking lots use an older technology that consumes more energy for a given Tight level than newer technologies. 9 ROSEMOUNT MINNESOTA; Fire Stations Johnson 'ij. Controls 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. fixed -set point 10 4ROSEMOUNT `1 MINNESOTA'" Both fire station garages are heated with gas -fired infrared heaters. A makeup air unit ventilates each garage with unconditioned air to remove contaminants from operating vehicles in the garage. Because the makeup air unit itself does not have heating capability, a gas -fired unit heater blows warm air into its discharge air stream. A makeup air unit with integral heating capabilities would provide more efficient and even heating of incoming air. room of Fire Station #1 to Tight the room when they Johnson Controls Some of the lights in the fire stations and the parking Tots use an older technology that consumes more energy for a given light level than newer technologies. Neither station uses occupancy sensors to control lighting use. Building personnel stated that they would appreciate an occupancy sensor in the dispatch come in at night. Occupancy sensors will also reduce energy use if lights are inadvertently left on when people leave the building. 11 Park Shelters Central Park Lift Station #1 2901145th Street West 4 ROSEMOUNT MINNESOTA Johnson Controls 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 system. 12 4 S i 4ROSEM@UNT NINNESOTA Johnson 0/1/40 Controls Most of the lights in the building use an older technology that consumes more energy for a given light level than newer technologies. The park shelters have outdoor building, trail, and ice rink lights that can be upgraded to consume less energy. 13 Well Houses and Lift Stations Each well house has an injection treatment system. The city has considered a centralized treatment plant but has not constructed one yet. A centralized plant can reduce chemical treatment and transportation costs and can provide a central point of control, which can reduce energy and operating costs. Johnson Controls 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. 14 Johnson 0/ Controls About half of the well houses have backup generators. The others have connections for generator hook up. None of the lift stations have permanent backup generators. Installing' permanent generators can prevent the need to rent and hook up portable generators in the event of a power outage. Delay in hooking up a portable generator can result in water shortages in times of need or costly clean up due to overflowing lift stations. 15 Table 1— Recommended Building Improvement Measures Johnson 0 0 Controls IIeH A413 Community Center and Arena Public Works St. Joseph's Church and School Fire Stations Park Shelters Well Houses and Lift Stations City Wide Building Automation System Lighting Upgrades and Occupancy Sensors 1 1 Building Envelope Improvements HVAC Improvements Premium Efficiency Motors Boiler Replacement /Upgrade Recommissioning Facility Performance Indexing (FPI) Water Conservation Vending Machine Controls Utility Rate Analysis and Rebates Emergency Backup Generators Water Meter Calibration Renewable /Sustainable Opportunities ROSEMOL MIN Johnson �a Controls Examples of Energy The following table have been identified which may Rosemount facilities. This section describes the improvement measures and the benefits that the City can expect from 16 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 4ROSEMOLINT MINNESOTA Johnson Controls 17 4ROSEMOLINT MINNESOTA centralize and network building facility personnel to monitor and control buildings wherever a LAN connection is available, providing greater flexibility of building operation. For some buildings, the expense of connecting to the City -wide network may not be justified. However, these buildings can still benefit from an internal building automation system that allows integrated control of various HVAC components. An opportunity exists to install DDC building automation systems in City facilities to reduce costs and increase efficiencies. These systems can be connected to the Johnson Controls trace a problem through the system to its source. Using the user interface and system 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. A DDC system can use an Ethernet LAN system to control. This allows 18 ItROSEMOUNTil Johnson ors, Controls City -wide LAN. This will standardize building control systems and centralize scheduling and control of HVAC equipment. Johnson Controls also recommends upgrading the SCADA system at the well houses to a fully wireless communication and control system. This upgrade can reduce maintenance and operating costs of the existing telephone -wire communication part of the system. Building Automation System Replace /update existing pneumatic control systems and stand -alone programmable thermostats with new digital control system Tie facilities into one centralized system that can be accessed via the Internet Program system to optimize energy use Upgrade SCADA system on domestic water system to full wireless Benefits Reduced energy consumption Increased control of building temperatures Improved system access Reduced maintenance costs Improved occupant comfort Increased Tabor efficiencies 19 ROSEMOUNT' MINNESOTA Johnson 010 Controls 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. Lighting Upgrades and Occupancy Sensors Replace existing fluorescent bulbs with lower wattage T8 bulbs Replace incandescent bulbs with compact fluorescent bulbs Replace metal halide lighting with pulse -start metal halide or fluorescent lighting, as appropriate Upgrade parking lot lights to more efficient lighting Install occupancy sensors where appropriate Benefits Reduced energy consumption Reduced maintenance costs Increased life expectancy of bulbs 20 ROSEM@UNT MINNESOTA Building Envelope Improvements Seal gaps, cracks, and holes in building envelopes Compartmentalize building zones in selected buildings Replace windows with low heat transfer resistance where appropriate Johnson Oi Controls 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. Benefits Reduced energy consumption Reduced drafts Increased indoor air quality Reduced potential for moisture issues Increased personnel comfort Protect building integrity 21 Johnson tO Controls HVAC Improvements 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. The Fire Station garages have makeup air units that bring unconditioned ventilation air install new ventilation systems in the 22 t "jf 4' 440 4ROSEM®UNT MINNESOTA into the buildings. This air is then heated by blowing hot air from a gas -fired unit heater into the air stream. This method of heating outdoor air is inefficient and results in uneven mixing of cold and warmed air. By replacing the existing makeup air units with new units that have integral heating capabilities; the units will operate more efficiently than unit heaters and result in a ste ady stream of warm air. Johnson 010 Controls IA 11 AI 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. HVAC Improvements Convert constant volume air handling units to variable volume at City Hall and Community Center Install ventilation and cooling in the St. Joseph's church and school Install makeup air units with heating capability in fire station garages Install infrared heat in park shelters Benefits Reduced energy consumption Increased comfort Reduced maintenance costs 23 Ice Arena Improvements reducing energy consumption. This technology is based on a naturally occurring protein that can be added to supply water to accelerate the formation of ice crystals. The compressors for the ice- making machine for the City's Ice Arena are at the end of their useful lives. At this advanced age, the compressors do not run as efficiently as new compressors and they have high maintenance costs. The City has budgeted to replace these compressors over the next several years. Johnson 01° Controls 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. Ice Arena Improvements Install dehumidification for the ice arena Evaluate technology to create ice at higher temperatures Install new energy efficient compressors for ice- making equipment Benefits Reduced energy costs Increased comfort Increased ice quality Reduced maintenance costs Improved indoor air environment 24 Benefits ROSEMOLINT 01 �ahnsan Controls MINNESOTA 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. Premium Efficiency Motors Duper =E Family Replace standard efficiency motors with premium efficiency motors Reduced energy consumption Reduced maintenance costs 25 ROSEMOU MINNESOTA Johnson 010 Controls 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. Boiler Replacement /Upgrade Install new energy efficient boilers Replace piping and heating coils as required Benefits Reduced energy consumption Reduced operating and maintenance costs Increased temperature control during shoulder seasons 26 ROSEMOLINT Recommissioning MINNESOTA a result of this poor system performance, personnel troubleshoot equipment and incrementally replace components in an attempt to resolve comfort issues. Johnson Controls would recommend to recommission building HVAC systems and equipment. Recommissioning includes verifying operation of HVAC system components and correcting deficiencies. Recommissioning also includes checking sensor calibrations, system set points and automation sequences of operation to verify that systems work together to provide a comfortable environment for building occupants. Recommissioning Verify HVAC system component operation Verify sensor calibration, set points, and sequences of operation Correct deficiencies identified Benefits Reduced energy consumption Increased personnel comfort Reduced maintenance costs Johnson Controls During normal system operation, wear and tear on valve and damper actuators can cause their performance to degrade. Sensor calibration can also drift, providing inaccurate input to control set points, resulting in sub optimal system response. Additionally, as systems are expanded and new equipment installed, operation is often not integrated between the various systems. This can result in excessive energy use as systems fight against each other to maintain building conditions. As maintenance costs increase as maintenance 27 9ROSEMOLUNT MINNESOTA Johnson 1 1,E Controls Facility Performance Indexing (FPI) Even well calibrated and otherwise functional systems do not always maintain space conditions throughout the wide range of building occupancy patterns and outdoor temperature swings. Current building operation in the City of Rosemount consists of 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. ftkiii.4,0 F twee 4#44sd i:4ir a! >•4rnaria Anatrs4 Currot arkwarct cj XIS Akd NScw I47.SJ Pfr.v141 CIE rr a:r..*11111.. 1a61 1 an ttomii4 INN 1 1:!

FPI displays a user friendly indication of how close parameters are to their set points, providing early indication when exceed a set point band. This allows operators to respond often before building occupants are aware of a problem. FPI also provides diagnostics when troubleshooting system performance. With FPI, operators and maintenance personnel can develop a predictive maintenance mindset 28 4 ROSEMOLINTA Johnson Of Controls performing maintenance tasks as system parameters start to slip but before they exceed set point. FPI aids in continuous system commissioning, which helps ensure that equipment continues to operate as designed and helps ensure optimum system performance and energy consumption. Installing FPI at selected City facilities will continuously monitor HVAC system performance.

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. flush valves 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 on urinals and toilets should be installed to help ensure they are flushed after each use to help maintain restroom The City of Rosemount currently fills tanks on trucks with water and drives throughout the city to irrigate flower beds and flood ice rinks. Localizing the water source with the point of use can reduce labor and fuel costs associated with these watering operations. cleanliness. Johnson vAll Controls The installation of an automatic irrigation system on city- maintained flower beds should be reviewed. An automatic system can adjust watering frequency and quantity based on soil moisture conditions and local weather predictions. This system can optimize the amount of water required to maintain plantings and reduce fuel and labor costs associated with driving throughout the City to water flower beds. 30 4 R0SEM@UNT M$NNESOTA Johnson {i Controls Extending water services to outdoor ice rinks should be investigated.

When buildings are unoccupied, it is not necessary to Tight the machines. Likewise, vending machines consume excess compressor energy as the compressors cycle regardless of building occupancy or space temperatures. By installing controls on City owned vending machines, energy consumption will decrease by approximately 45 percent. Compressor cycling is based on room temperature and occupancy. The major soda machine vendors have approved this technology because it reduces the energy usage of these plug loads by automatically cycling them off when they are not needed, but does not compromise the vending equipment availability and reliability. This technology has been proven to keep products cold meeting the soda company specifications. It also extends compressor life by reducing operating hours. Vending Machine Controls Install controls on vending machines Benefits Reduced energy consumption Increased compressor life Reduced maintenance costs 32 ,CROSEM@UNT MINNESOTA Johnson Via Controls 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. energy efficient Utility Rate Analysis and Rebates Analyze utility use to optimize rate structure Apply for and track available utility rebates Benefits Reduced utility costs Decreased project costs from application of rebates 33 ROSEMOUNT MINNESOTA 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. Johnson 0 Controls Emergency Backup Generators Install backup generators at selected facilities Investigate feasibility of peak shaving or interruptible electric rates Benefits Reduced operating costs Reduced utility costs with peak shaving Increased performance during power outages 34 ROSEMOUNT MINNESOTA"" 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. Johnson 1 ∎6 Controls Automatic Meter Reading (AMR) and Meter Calibration Calibrate municipal water meters Benefits Increased meter reading accuracy Increased revenue from calibrated meters 35 Johnson 1 ti Controls 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 Sustainable Design Building Rating Johnson Controls is a leader in the design and implementation of Leadership in Energy and Environmental Design for New Construction (LEED -NC) and Existing Buildings (LEED- EB). In addition to LEED -EB, Johnson Controls can perform an Energy Star evaluation of certain City buildings. The Energy Star performance rating is a benchmark that helps energy managers assess how efficiently their buildings consume energy, relative to similar buildings nationwide. Renewable Applications Benefits Reduced energy costs Renewable energy source LEED -EB points for accreditation Increased public awareness of sustainability and environmental design Potentially reduced insurance premiums 36 $600,000 $500,000 $400,000 $300,000 $200,000 $100,000 ROSEM@UNT MINNESOTA IV. Utility Analysis Based on our building surveys and analysis of the City of Rosemount's energy requirements, Johnson Controls estimates that the City can reduce their energy costs from $871,000 to $709,000 or $162,000 annually. This represents a 19 percent reduction in energy expenditures. During project development, Johnson Controls engineers will perform a more detailed analysis of energy consumption and savings potential. Tables 1 and 2 give a visual representation of current and proposed energy consumption on an individual building basis and a City -wide basis.

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. 40 ROSEMOUNT Johnson Controls VI.

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 Controls meets the criteria established in the PDA and the City does not move forward with a Performance Contract, the City will be invoiced for the PDA cost. We look forward to exceeding your expectations! 43
