The IGA describes how ConEdison Solutions® (“CES”) plans to implement Energy Conservation Measures (ECMs) at municipal buildings and schools throughout the city. This proposal represents the results of CES’s assessment of the energy savings, cost reductions, and energy efficiency and infrastructure improvements that can be accomplished under an Energy Savings Performance Contract (ESPC). CES is pleased to offer this proposal to implement a comprehensive set of Energy Conservation Measures (ECMs) for the City of Northampton and we look forward to serving the on-going dynamic needs of the City while providing energy efficient solutions to infrastructure upgrade projects. CES proposes to invest $7,665,760 in energy efficiency equipment upgrades at the municipal and school buildings that will yield an estimated $695,000 per year in estimated energy savings based on FY2009 energy prices. The project financing term will be 15 years, assuming that: 1) The actual utility rebates approved by National Grid totals at least $362,000, which is the estimated utility incentive amount used to develop the ESPC contract. If the final utility- approved rebates are greater or lesser than this estimated amount, then the contract term or the City’s capital contribution will be adjusted as necessary to account for the change in rebate amount. 2) The gas utility agrees to fund the installation of new or upgraded natural gas lines to the various buildings being converted from fuel oil to natural gas (Municipal buildings, DPW, Waste Water Treatment Plant). 3) Permanent financing rates of 3.5% are available and are procured by the City based on its tax-exempt status. 4) Energy price inflation of 3% applies throughout the contract term. (CES guarantees savings based on units of energy use, not energy prices or total utility costs.) 5) All energy savings accrued during the construction phase will be used by the City of Northampton to reduce the total financed amount. 6) CES will reimburse the City if actual savings fall below guaranteed savings (approximately 75% of anticipated actual savings), assuming that the City engages CES on an annual basis to provide Operations and Maintenance oversight services and annual Measurement and Verification services. 7) The City diligently maintains and services the equipment installed by CES and, if any equipment fails in service, replaces it with equipment that has similar or better operating efficiency and is compatible with the controls used to operate the equipment according to CES’s specifications. Executive Summary City of Northampton ESPC February 16, 2010 ConEdison Solutions 1-2 Proprietary and Confidential 8) All other operating and environmental parameters specified by CES in its detailed energy simulations are followed throughout each year of the term of the agreement. Table 1 provides summary-level project information organized by ECM technology. The summary data includes each ECM’s: costs, anticipated rebate amounts, annual total savings, and simple payback period in years. A cost breakdown of all fees is presented in Appendix B. Additional supporting calculations, measure descriptions, and assumptions are provided in Section 3 of this IGA, as well as in the various Appendices which contain site-specific engineering analyses and cost calculations for the ECMs proposed to be implemented.

INTRODUCTION The City of Northampton has elected to use the Energy Savings Performance Contract (ESPC) process to obtain the professional services of an experience energy service company (ESCO) to upgrade the infrastructure of its facilities, utilizing the contract vehicle defined by Massachusetts General Laws, Chapter 25a, Section 11i. ConEdison Solutions is an ESCO qualified to provide energy management and implementation services under this contract vehicle. ESPC Process and Contacts The City of Northampton pursued ESPC project development under a “Request for Quotation” process, and in mid-2009 ConEdison Solutions was notified by the City of Northampton of its selection to develop an ESPC Project at the City of Northampton’s facilities. ConEdison Solutions submitted an Initial Proposal to the City of Northampton in early Fall 2009. The Initial Proposal was updated and finalized in September 2009, and ConEdison Solutions was authorized to prepare a Investment Grade Audit for specific customer-selected projects presented in the Initial Proposal. Upon approval, ConEdison Solutions will proceed to the Construction Phase that will implement the projects described herein. The following table summarizes the role of key project team members in the development of the City of Northampton’s pursuit of an ESPC with ConEdison Solutions.

This ESPC proposal covers most, but not all, of the buildings at these five departments, which together comprise over 1,050,000 square feet of occupied area. A total of 36 buildings are proposed to be upgraded via this ESPC. Building Construction and Usage Summary Newer buildings at the three sites are generally constructed with steel framing with batt or rigid board insulation and siding comprised of brick, concrete block, wood/vinyl, or metal panels. Windows are primarily double paned, metal or wood framed. Metal framed windows generally are tight fitting, while the wood windows in various applications range from tight fitting to loose. Most facilities are operated for one shift per day, plus significant weekend recreational activities each month. Efforts have been ongoing for some years to increase the energy efficiency of the buildings, with most of the largest buildings (schools) having a new DDC energy management system installed last year and with some buildings having high-efficiency T-8 lighting installed. Most personnel appear to be conscientious in turning off lights and turning down heat at night, using manual methods in many instances. A summary description of the City of Northampton facilities covered in this DES is presented in the following table: Introduction and Baseline Approach City of Northampton ESPC February 16, 2010 ConEdison Solutions 2-3 Proprietary and Confidential Table 2.2: City of Northampton Building Description Summary Facility Designation Size Function Construction * HVAC Systems * See Appendix B bin models for details * See Appendix B bin models for details Municipal Administration City Hall 16,962 s.f.Offices Stucco-faced, heavy-weight stone construction;

These energy models are provided in Appendix A for all of the buildings being retrofitted and incorporate data collected during site visits and metering and verification activities over the past 4 months. Following each of the building energy models in Appendix A are Measurement and Verification (M&V) Protocols proposed to be used to verify equipment operations and savings, and Pre-Construction M&V graphs for selected equipment that was metered to document existing operating conditions and loads. The following sections describe the building simulation techniques used to quantify energy savings and simulate overall building use before and after implementation of the proposed ECMs. Introduction and Baseline Approach City of Northampton ESPC February 16, 2010 ConEdison Solutions 2-13 Proprietary and Confidential Overall Building Simulation Methodology A temperature-bin-based building simulation model was used for calculating energy consumption of the building under baseline conditions and after implementation of all measures. All calculations (listed below) are based on standard engineering formulas and use inputs that have been verified through detailed evaluations of each buildings construction and energy-using systems. Introduction and Baseline Approach City of Northampton ESPC February 16, 2010 ConEdison Solutions 2-14 Proprietary and Confidential Building Simulation Input Sections All energy-using systems in each building are included in the model with specific equipment inventories, metered or measured data, nameplate information and building structural components.

All data, efficiencies, capacities and temperatures are explicitly shown for review and approval by City of Northampton. All equations used in the model are simple, engineering-based formulas that are standard in the industry. Utility bills were used in calibrating the model to reflect total consumption of each energy source for each building. The actual inventory of equipment and loading for the building was also entered and simulated individually for occupied and unoccupied hours throughout the year. Overall building energy use parameters (btu/s.f., s.f./ton, etc.) were calculated to verify that the modeled baseline energy use was reasonable and comparable to similarly designed and operated buildings based on ConEd Solutions' experience. Also embedded in the building models are the specific M&V plan for verifying each of the critical parameters used in calculating energy savings. Based on annual M&V activities, the savings capability of the systems installed by ConEdison Solutions will be verified and quantified. 2.6 OPERATIONS & MAINTENANCE BASELINE Facility operations and maintenance (O&M) activities are currently performed by base personnel. Implementing the ECMs identified within will result in overall lower maintenance costs. However, no O&M savings are proposed to be included in this Investment Grade Audit for use in helping to pay the debt service and reduce the length of the financing term. ConEdison Solutions will provide reports of quarterly reviews and inspections of key equipment and control systems for the first three performance period years. For the remaining years of performance period, these reviews will be done semi-annually. These reports will assure peak operational efficiency is maintained and all required maintenance services are being provided. 3 ENERGY CONSERVATION MEASURES February 16, 2010 ConEdison Solutions 3-1 Proprietary and Confidential 2 3.1 ENERGY CONSERVATION MEASURES (DETAILED DESCRIPTIONS) ConEdison Solutions recommends implementation of the following Energy Conservation Measures (ECMs).

Existing/Base Case Conditions A wide variety of T8 lamps and ballasts were observed throughout the City and these fixtures range in age from 5 to 12 years old. They represent older technology and some will be near end-of-life for their ballasts within 5 – 10 years. The City is required to maintain a diverse stock of lamps and ballasts to service these various generations of T8 fixtures. Energy Conservation Measures City of Northampton ESPC February 16, 2010 ConEdison Solutions 3-10 Proprietary and Confidential Proposed Modifications: This measure would be implemented in addition to Option 1a lighting measures. Option 1b includes option 1a above as well as the retrofit and/or replacement of all T8 lamps/ballasts with new Super T8/electronic ballasts. This measure was pursued at the request of Northampton in order to standardize on the types of lamps and ballasts used in the city. Project Incremental Economics: This measure results in additional savings of approximately 231,000 kWh at an additional cost of approximately $800,000, yielding a simple payback period of approximately 20 years. Adding this measure to Option 1a still provides a good overall payback period for the overall lighting measure.

Other Measures Considered But Not Recommended: None Florence Fire Station – Burner Upgrade ECM Summary: The existing heating plant in the Florence Fire Station consists of one oil-fired hot water boiler that heats perimeter radiation and coils in the building. Several operational features of the system cause the boiler to operate inefficiently: - The system is unable to purge air properly due to undersized expansion tank. - The existing piping arrangement is inadequate, the pumps are noisy and vibrate severely, and the entire pumping and piping system needs to be reconfigured. - The heating system boiler is also used to heat a large indirect domestic hot water tank in the winter. Energy Conservation Measures City of Northampton ESPC February 16, 2010 ConEdison Solutions 3-17 Proprietary and Confidential Existing/Base Case Conditions: Currently the heating system consists of one oil fired hot water boiler, circulation pumps on three zones and domestic hot water tanks. The main boiler is used to heat domestic hot water through a large storage tank with an indirect HW coil. The water is fed from this tank to a supplementary electric DHW heater that serves as the primary source of DHW heating in the summer when the main boiler is shut off. Proposed Modifications: Replace the existing oil-fired burner with a gas-fired high efficiency burner including repair of existing hot water piping and replacement of the expansion tank. The City would be expected to enter into a gas purchase agreement in order to offset the cost of gas service installation. As part of this work the stack would be relined with AAl 29-4C Stainless Steel. (see drawing in appendix) Equipment to be Installed Quantity Equipment Details Burner 1 Powerflame, Webster or equal Benefits: - Energy savings through fuel switching to gas Exclusions: - Underground oil tank removal and disposal of waste oil - Installation of gas line from street to meter (gas utility assumed to provide this at no cost to Northampton) Other Measures Considered But Not Recommended: Energy Conservation Measures City of Northampton ESPC February 16, 2010 ConEdison Solutions 3-18 Proprietary and Confidential - Boiler replacement Academy of Music – HVAC Upgrades ECM Summary: Install destratification fan in main hall, add hot water coils to attic air handlers and convert oil fired burners to dual fuel. Existing/Base Case Conditions: The Academy of Music was recently redesigned and converted from steam boilers to hot water boilers with European-style modern hot water radiators along the walls of the aisles. The capacity of the radiators is compromised by the inadequate HW piping (1/2” piping run in series, instead of ¾” to 1” parallel piping as called for in the engineering plans). The steam boilers were replace with high-efficiency hot water boilers and a pair of large HW distribution pumps were installed that operate continuously throughout the heating season. The main theatre requires nearly continuous operation of its heating system throughout the winter because of inadequate capacity in the existing heating system. New hot water “European-style” radiators were installed recently, but are undersized, piped inadequately, and small for the large volume of the theatre. Because of these design defects, warm –up times are excessive and the system must operate at all times. This is wasteful since the theatre is only occasionally occupied a few times per week. Attic air conditioning systems High ceiling height in Theatre There is little downward air movement from the top of the theatre to the occupied zone at ground level, resulting in warm temperatures in the balcony and cold spots on the main seating area. Energy Conservation Measures City of Northampton ESPC February 16, 2010 ConEdison Solutions 3-19 Proprietary and Confidential Additional heating problems occur in the rear offices due to end-of-run circulation restrictions, requiring this area to use electric heaters throughout much of the heating season. Proposed Modifications: Install a 20’ diameter de-stratification fan in the center hall ceiling medallion. Install one hot water coil on each of (2) air handlers (AHU-3 & -4) in attic space, including hot water piping. Install local radiator thermostats in the rear office above the stage and improve HW flow through use of a supplementary HW pump. This will allow reduction or elimination of the use of electric heaters in this area. Remove existing oil-fired burner and replace with dual-fuel burner including gas piping and chimney liner.

Other Measures Considered But Not Recommended: Boiler replacement Energy Conservation Measures City of Northampton ESPC February 16, 2010 ConEdison Solutions 3-20 Proprietary and Confidential Forbes Library – Dehumidification System for Coolidge Library and Local History Room ECM Summary: Install new equipment to provide optimum archival storage conditions in the Local History Room and the Coolidge Presidential Library. Existing/Base Case Conditions: Existing air handling equipment was not designed to provide adequate dehumidification or humidification of these archival spaces, resulting in premature deterioration of invaluable historical documents. The air conditioning equipment utilizes chilled water which cannot provide optimum conditions (65-70F and 45% RH throughout the year). Proposed Modifications: Replace AHU-2 and AHU-4 with high efficiency heat-recovery dehumidification units. (See drawing in appendix). The dehumidification units will be equipped with external condensing units so that the units can provide cooling independent of the main chiller plant. This will assure adequate environmental conditions while minimizing the us of the chillers. Humidification modules will also be provided that will assure controlled humidity conditions in the winter. Air flow will also be increased to address problems with inadequate air throw in the existing air handling units, resulting in discomfort in the office of the curator of the Coolidge Presidential Museum.

Other Measures Considered But Not Recommended: None City Hall – Burner Upgrade ECM Summary: Install new dual fuel oil/gas burner on the existing boiler. Existing/Base Case Conditions: The existing steam boiler is oil-fired only. Energy Conservation Measures City of Northampton ESPC February 16, 2010 ConEdison Solutions 3-22 Proprietary and Confidential Proposed Modifications: Install new dual-fuel (oil and gas) burner on the existing boiler. (see drawing in appendix) Equipment to be Installed Quantity Equipment Details Burner 1 Powerflame, Webster or equal Benefits: - Cost savings from fuel switching Exclusions: None. Other Measures Considered But Not Recommended: New Boiler The existing boiler is in relatively good condition. A conversion of the building to hot water was considered, but determined not to be cost-effective since it would require the replacement of many of the existing steam radiators with fan-powered convectors. The energy savings was insufficient to justify this measure. Water-source heat pumps Water-source heat pumps were considered for City Hall, but the cost of the system was determined to be excessive for the energy savings that are possible from this retrofit. This measure was found to have a simple payback in excess of 30 years and is considered a comfort and noise improvement project rather than an energy- saving project. The proposed design required inclusion of a significant number of electric resistance heating units to provide minimal heating to spaces, such as toilets, basement areas, and storage areas that do not require cooling and do not have sufficient heating loads to justify the cost of a heating-only water-source heat pump.

JFK Middle School – Install VFDs and Bypass Pumps in Pool Mechanical Room ECM Summary: Upgrade the pumping system within the pool mechanical room with variable speed drives and bypass pumps to reduce overall pumping energy use and improve control of water flow.. Existing/Base Case Conditions: The pool mechanical room has several interrelated pumps and bypass lines: • Main pool filter circulation pump (currently fixed speed with throttling valve) • Dectron heater circuit bypass pump (currently fixed speed and operated continuously) • Auxiliary pool water heater bypass lines (currently receives flow through a main circulating line throttling valve). These pumps operate 24/7 and consume significant amounts of electricity. Energy Conservation Measures City of Northampton ESPC February 16, 2010 ConEdison Solutions 3-31 Proprietary and Confidential Main Pool Filter Circulating Pump Aux. Heater Lines (left) and Dectron Pump and Heater Lines (right) The water flow through the sand filter is currently regulated only via a throttling valve and excessive flow rates and suction cavitation have been recurring problems with this system. Proposed Modifications: 1. Install variable speed drives (VFD) and a new premium high-efficiency (PHE) motor on the main pool water circulation pump. The throttling valve will be opened fully and the speed manually adjusted to meet current pool circulation requirements. This will save electrical energy by reducing both flow rate and pump outlet pressure. 2. Install a VFD and PHE motor on the existing Dectron bypass pump and control via the EMCS to operate only when needed for pool water heating. The Dectron provide “free” pool water heating when the Dectron unit is not calling to heat the natatorium space itself. This heating source will be preferentially used before the auxiliary heater system is activated. The pump will be equipped with a VFD and set manually at the optimum flow rate for the Dectron unit. 3. The auxiliary heater bypass throttling valve will be opened fully, and a new bypass pump with VFD and PHE motor will be installed (similar in design to the existing Dectron bypass pump) and will be operated only when needed for supplementary pool water heating. This will permanently eliminate a major pressure loss through the main pool pump circuit, permitting the main pool VFD to be further reduced in speed.

Wastewater Treatment Plant – Sludge Processing Building (SPB) – Replace Existing Makeup Air Unit on 2nd Floor; Install VFDs to Reduce Air Flows During Unoccupied and Occupied Periods ECM Summary: The propane-fired makeup air unit and associate Odor Control Fan operate continuously and the MAU has had operational problems for some time. The MAU will be replaced and VFDs installed to control air flows and allow the MAU to be turned off at night. Existing/Base Case Conditions: The existing MAU (Reznor) feeds 100% outdoor air, heated to approximately 70 degF to the 1st and 2nd floor areas of the Sludge Processing Facility, and is used to makeup the air removed by the Odor Control Fan serving these areas. The Reznor unit has had operating problems for some time, resulting in frequent outages, numerous high servicing bills, and excessive use of propane (nearly 50,000 gallons per year, based on DPW records). This unit replaces the air being continuously withdrawn by the odor control fan, which currently operates with a two speed motor manually set at low speed (2/3). This fan is currently oversized since it was originally designed to exhaust the anaerobic digester building, which has been decommissioned and the exhaust duct manually shut off. The Energy Conservation Measures City of Northampton ESPC February 16, 2010 ConEdison Solutions 3-33 Proprietary and Confidential existing Reznor unit also introduces snow and rain into the filter media due to the design of the intake louver, requiring the maintenance personnel to open the inside door of the unit and remove the filter media to maintain operation. Reznor Makeup Air Unit in SPB Odor Control Fan (Roof of SPB) Proposed Modifications: Install new high-efficiency, variable speed drive makeup air unit to replace the existing MAU, which is at end-of-life. The unit will be controlled via the new energy management system (covered under ECM-4) to operate only during occupied hours (M- F; 6 am – 2 pm). After these hours the MAU will be shut off or turned down to minimum speed. The odor control fan will also be modified to reduce its speed through a sheave and belt change and a VFD installed such that at 100% speed it operates at a sufficient volume to maintain a negative pressure in the SPB. At night, the odor control fan will be slowed down to maintain a negative pressure in the SPB with the new MAU shut off. Proposed Modifications: Install new rooftop 100% outside air system and controls. Add 316 stainless steel, 30” diameter automatic actuator to odor control suction blast gate. Remove existing 40 HP motor, resheave, install new 25 HP high efficiency motor with VFD. Install methane and CO sensors to activate alarm and start system during unoccupied times.

Energy Conservation Measures City of Northampton ESPC February 16, 2010 ConEdison Solutions 3-39 Proprietary and Confidential 3.4 ECM-4 ENERGY MANAGEMENT SYSTEM (EMS) General ECM Information: The buildings listed in the table below have a wide array of control systems ranging from local pneumatic controls to building wide Energy Management Systems as identified in the following pages. While these systems have been fairly well maintained there are many systems that are in need of repair, upgrade, or complete replacement. Contained in this section are site specific scopes of work that we are proposing to implement as part of this project with the City of Northampton. As part of our EMS design process and system selection criteria we considered many factors such as customer requests, product serviceability, product availability, ease of use, and availability of local support. With that in mind we set out to provide the City of Northampton with an EMS system that had an expandable architecture, is easy to understand and troubleshoot, and was comprised primarily of components that can be purchased from multiple suppliers and replaced by the City’s Maintenance Staff. The design and EMS architecture selected for this ECM will enable the City of Northampton to have Web-based access to the buildings listed below that have either a Johnson Controls (JCI) or Automated Logic (ALC) EMS. Where a new EMS is being installed or an existing JCI EMS is being upgraded, the new system will be manufactured by JCI and will be comprised of their current Extended Architecture product line including a new server to manage the sites. The new EMS will allow authorized users Web-based access to the EMS and include the powerful ADX server software package which will allow up to 25 concurrent users. In buildings where there is an existing ALC EMS we will expand that existing system by adding new points as identified in this section. We believe that short of removing all of the existing ALC control systems this is the best and most economical approach for the City of Northampton. Energy Management System Setpoints and Programming As part of our comprehensive approach to this Energy Conservation Measure we have included Retro-commissioning of the existing to remain controls in the facilities as identified in this section. For the buildings that have local pneumatic controls that will remain we have included an itemized allowance to replace failed components based on field surveys of the existing systems.

Multiple Buildings throughout Northampton - Install New Steam Traps and Radiator Valves ECM Summary: Install new steam traps to save energy and new self-contained radiator valves to improve comfort in the space during occupied hours. Properly operating steam traps reduce Energy Conservation Measures City of Northampton ESPC February 16, 2010 ConEdison Solutions 3-105 Proprietary and Confidential occupied space overheating resulting from traps that have failed in the “open” position, thereby saving energy. Thermostatic, self-contained radiator valves will provide more accurate control of space temperatures, increasing occupant comfort. Existing/Base Case Conditions: A number of the steam traps throughout the various buildings have failed or are leaking. Based on observations and discussions with maintenance staff, we believe that water hammer may be occurring throughout the steam distribution systems. Other issues with the existing steam distribution system have been identified as well including manual radiators or fin tube convectors with failed control valves (thermostatic, electric, or pneumatic). Energy Conservation Measures City of Northampton ESPC February 16, 2010 ConEdison Solutions 3-106 Proprietary and Confidential Proposed Modifications: Two options are being proposed for the City of Northampton. Option # 1: Install new mechanical steam traps Replace all existing mechanical steam traps with new Float &Thermostatic steam traps Tunstall Series TA-FT or equivalent to eliminate losses related to failed open and leaking traps. Also replace unit heater traps, heat exchanger traps with new F&T steam traps, and install new ISTEC Thermostatic Radiator valves (models # 2260, 2270, or 2290) or equivalent for cast iron radiator or fin tube convectors. A total of 319 steam traps are planned to be replaced. Buildings with proposed new steam traps are listed in the following table: Energy Conservation Measures City of Northampton ESPC February 16, 2010 ConEdison Solutions 3-107 Proprietary and Confidential Item Description Qty City Hall New Steam Traps (Thermostatic/F&T Series TA or TA-FT) 4 New Unit Heater Steam Trap s (Series TA or TA-FT)1 New Thermostatic Radiator Valve and Steam Trap for Cast Iron Radiator or Fin Tube (ISTEC # 2260, 2270, or 2290)42 Memorial Hall New Steam Trap s (Thermostatic/F&T Series TA or TA-FT )4 New Unit Heater Steam Trap s (Series TA or TA-FT)1 New Thermostatic Radiator Valve and Steam Trap for Cast Iron Radiator or Fin Tube (ISTEC # 2260, 2270, or 2290)40 Smith Vocational Building B Shop Area New Steam Trap s (Thermostatic/F&T Series TA or TA-FT )8 Jackson St Elementary New Steam Trap s (Thermostatic/F&T Series TA or TA-FT )23 New Unit Heater Steam Trap s (Series TA or TA-FT)2 New Unit Ventilator Steam Trap s13 New Thermostatic Radiator Valve (exisiting Spartan electronic valves - thermostatis valves not included) and Steam Trap for Cast Iron Radiator or Fin Tube (ISTEC # 2260, 2270, or 2290)27 New AHU Steam Trap s (Series TA or TA-FT)5 New Heat Exchang er Steam Trap s (Series TA or TA-FT)2 Leeds Elementary New Steam Trap s (Thermostatic/F&T Series TA or TA-FT )14 New Thermostatic Radiator Valve and Steam Trap for Cast Iron Radiator or Fin Tube (ISTEC # 2260, 2270, or 2290)6 New Heat Exchanger Steam Traps (Series TA or TA-FT) 2 Feiker Building New Steam Trap s (Thermostatic/F&T Series TA or TA-FT )9 New Thermostatic Radiator Valve and Steam Trap for Cast Iron Radiator or Fin Tube (ISTEC # 2260, 2270, or 2290)10 New Unit Ventilator Steam Trap s (Series TA or TA-FT )7 Florence Senior Center New Steam Trap s (Thermostatic/F&T Series TA or TA-FT )12 New Unit Ventilator Steam Traps (Series TA or TA-FT) 24 New Thermostatic Radiator Valve and Steam Trap for Cast Iron Radiator or Fin Tube (ISTEC # 2260, 2270, or 2290)58 Forbes Library New Steam Trap s (Thermostatic/F&T Series TA or TA-FT )2 New Heat Exchang er Steam Trap s (Series TA or TA-FT)1 New AHU Steam Traps (Series TA or TA-FT)2 Total 319 Benefits: - New mechanical steam traps will save steam plant energy and reduce future steam trap maintenance needs. Energy Conservation Measures City of Northampton ESPC February 16, 2010 ConEdison Solutions 3-108 Proprietary and Confidential Exclusions: Price does not include Asbestos abatement. Other Measures Considered But Not Recommended: None. Option # 2: Install new orifice steam traps Replace all existing mechanical steam traps with new SteamLoc (or equal) orifice type steam traps to eliminate losses related to failed open and leaking traps. A total of 319 steam traps are slated for replacement as shown in the previous table. Buildings with proposed new steam trap application are also as listed in the previous table. Benefits: - New steam traps will save steam plant energy and reduce future steam trap maintenance needs - Orifice traps will have a much longer life than mechanical traps - Orifice traps, since they cannot fail open, save additional energy over time when compared with mechanical traps - Repair of orifice traps that fail closed (usually due to plugging because of poor water treatment) are easily cleaned out and quickly put back into service Exclusions: Price does not include Asbestos abatement. Other Measures Considered But Not Recommended: None. Recommendation: At this time, the cost of Option 1 (mechanical traps) is somewhat lower than for Option 2 (orifice traps) but Option 2 saves somewhat less energy over the long term due to higher failure rates for mechanical traps compared to orifice traps. Some significant reservations were expressed by Northampton maintenance personnel as to the long-term viability of orifice traps, however, and although ConEdison has had good experiences with these types of traps, we will follow the preference of Northampton’s facilities staff for installation of new mechanical steam traps. Smith Vocational HS – Building B – Improve Comfort in Plumbing Shop ECM Summary: Energy Conservation Measures City of Northampton ESPC February 16, 2010 ConEdison Solutions 3-109 Proprietary and Confidential Install long-throw diffusers in the Plumbing Shop to force warm air to the occupied lower level of the shop. Existing/Base Case Conditions: The Plumbing Shop experiences poor comfort and high energy use during cold weather since the heat provided by the Carrier heat unit has insufficient velocity as it leaves the ductwork to make it to the floor. This problem was traced to a poor mechanical installation that use oversized circular diffusers that provide very low flow velocity at the outlet based on the CFM capacity of the heating unit. This results in the system operating longer hours than necessary and heating the upper portion of the shop to high temperatures, increasing heat losses through the walls and ceiling. Proposed Modifications: Remove (4) existing diffusers, repair ductwork and install appropriate diffuser designed to throw air to floor level. Benefits: - Improved comfort for occupants of Plumbing Shop - Reduced heat losses through walls, roof, and garage doors Exclusions: Sealing of the garage doors is necessary for improving the comfort of occupants. This measure is being proposed under the Building Shell ECM and is assumed to be implemented under that ECM. Other Measures Considered But Not Recommended: None. Energy Conservation Measures City of Northampton ESPC February 16, 2010 ConEdison Solutions 3-110 Proprietary and Confidential Smith Voc Multi-Species Barn - Eliminate Space Heating in Storage Areas ECM Summary: Remove the heating system from the Multi-Species Barn storage areas and add insulation and heat trace to the domestic water piping that runs in these areas. Install freeze- resistant hot and cold domestic water faucets. Existing/Base Case Conditions: The storage areas of the Multi-Species Barn are heated using hot water coils and have very high heat losses because of a lack of insulation and large air leaks to the outside through gaps in the sliding garage doors in this area. The area does not store products that would suffer from below-freezing temperatures. Proposed Modifications: Eliminate the hot water heating coils from the storage room and allow the room to drop to ambient outdoor conditions throughout the winter. Provide heat trace and insulation to the domestic hot and cold water pipes in the area and install faucets designed for freezing conditions. Benefits: - Reduced energy consumption - Reduced potential for hot water heating coil freeze-ups. Exclusions: Sealing and/or replacement of the sliding doors is not included in this measure. Other Measures Considered But Not Recommended: Improved sealing of the sliding doors and the addition of wall and ceiling insulation was considered, but is not recommended due to the long payback period and the superior economics of eliminating heating altogether for this area. Energy Conservation Measures City of Northampton ESPC February 16, 2010 ConEdison Solutions 3-111 Proprietary and Confidential Florence Community Center - Minor Equipment Upgrade ECM Summary: Eliminate the existing electric domestic hot water heaters and circulating pump in the garage next to the boiler room and install instantaneous DHW heaters in the buildings’ (3) restrooms. Existing/Base Case Conditions: An electric DHW heater is located in an unheated garage next to the boiler room and is equipped with a DHW recirculation pump that operates continuously. This system has significant standby and distribution heat losses and is in a facility that has relatively low DHW use. Proposed Modifications: Install instantaneous DHW heaters in the following areas: - Main toilets - Small toilet in old principal’s office on 1st floor Benefits: - Energy savings - Instant hot water availability to users - Reduced maintenance on DHW storage tank and circulating pump Exclusions: Existing equipment will be drained and abandoned in place.

Proposed Modifications: Install an aquastat and on/off controls for the pump to reduce pump operation to maintain a return water temperature of approximately 90 degF. Benefits: - Reduced energy consumption - Reduced wear on pump Exclusions: None. Other Measures Considered But Not Recommended: None. Water Treatment Plant - Install Actuators and Dampers for Boiler Combustion Air Intakes Pump ECM Summary: Install combustion air intake dampers (2) and actuators to close off infiltration when the boilers are not firing. Existing/Base Case Conditions: The mechanical equipment room (MER) on the first floor of the relatively new Water Treatment Plant gets quite cold in the winter and is subject to severe drafts through two (2) open ducts (one high, one low in the room) that provide combustion air to the two boilers in the MER. These ducts were never equipped with dampers or actuators, and so allow cold air to blow unrestricted into the boiler room from the outdoors. This causes the heaters in the room to operate more than necessary and also cools of the boilers and large domestic water heater that is located in the MER. Because the hot water heaters cannot keep up with the demand for heating, the two man-doors to the MER must be propped open to allow heat from adjacent areas to provide supplemental heat to the MER. Energy Conservation Measures City of Northampton ESPC February 16, 2010 ConEdison Solutions 3-113 Proprietary and Confidential Proposed Modifications: Install two (2) sets of dampers and actuators with controls to open the dampers proportionately only when 1 or 2 boilers are firing.

Nameplate data has been recorded and is included in Appendix B ECM-11. Estimated hours and estimated motor loads were inserted for each motor and the existing and proposed motor efficiencies were also inserted. Based on the kWh Energy Conservation Measures City of Northampton ESPC February 16, 2010 ConEdison Solutions 3-142 Proprietary and Confidential savings and dollar savings, selections were made of motors that justified replacement with premium high-efficiency motors. The general conclusion of this survey was that for motors that are not near end-of- life, it is not economical to replace the motors unless the motors have: 1. Very long run hours (nearly continuous) 2. High loading 3. Horsepower in the range of 1 HP to 40 HP Very few of the motors surveyed met all of these criteria, and most were determined to be uneconomical to replace at this time. Those motors that justify replacement are listed on the following page. If, in the future, Northampton finds a need to replace a motor due to failure or need for rewinding, it is recommended that Premium High Efficiency motors be considered instead of standard motors. If PHE motors are specified, careful consideration of the speed of the motor is necessary since PHE motors tend to run slightly faster than standard motors and unless the end use equipment is slowed down proportionately, much or all of the savings can be lost. Install Premium High Efficiency Motors in Selected Applications with High Use ECM Summary: Replace (4) motors in various mechanical rooms with Premium High Efficiency motors..

Our project management structure assigns roles and responsibilities according to each team member’s expertise and allows for continuity among staff throughout the project duration. Team members involved during the design phase, are also involved during the operations and maintenance phase. Our project organization and management processes take into account the unique nature of managing a wide range of projects at geographically dispersed facilities. ConEdison Solutions provides operation and maintenance training to ensure the installed equipment is properly managed in order to maximize benefits. Our program provides the City of Northampton’s facilities staff with an understanding of the proper operation and maintenance of the equipment and systems supplied. ConEdison Solutions also trains the facility’s staff on how to collect and record equipment performance data; this data is used to verify that the equipment is functioning properly. ConEdison Solutions develops a customized training program once the list of ECMs have been are identified, CES will develop a site-specific, customized training program to be offered to support each installed ECM. We offer a one week hands-on classroom training to staff post commissioning. Annual refresher training via on site visits will be provided over a multi-year term. 3 3 3 3 3 3 3 3 3 3 SITE MANAGEMENT APPROACH Implementation Management Approach City of Northampton ESPC February 16, 2010 ConEdison Solutions 4-2 Proprietary and Confidential 4.2 ORGANIZATION Ken Nathanson is the primary, single point of contact and he will provide continuity of management throughout the project phases. John Johnson, the Customer Solutions Development Senior Coordinating Engineer of ConEdison Solutions in our Burlington, MA office, has the responsibility and authority to manage the ESPC projects at the facility, drawing on his own staff and corporate resources to support the project. The project activities can be classified into three phases: 1. Audit, Design, and Engineering 2. Construction and Implementation 3. Maintenance and Operations (Performance Period) Although each phase is technically and contractually treated separately, our experience indicates that projects are most successful when there is overlap among the teams that execute each phase. So, while the tasks and responsibilities are always specified quite clearly to reflect staff capabilities, each phase is enhanced with the knowledge and capabilities of staff and managers who are involved in the other phases. The City of Northampton will therefore see our M&V experts involved in the project development phase, as well as our design engineers interacting with our implementation managers. The table below identifies the key staff and their specific responsibilities. It highlights that not all individuals are involved in each phase of the project. Moreover, assignments generally need to be modified during the evolution of each project – for example, Mr. Nathanson will assign a primary site “point of contact” or change other assignments, to reflect the work during each major phase of the project. We identify these individuals in the table below, and include additional categories that we believe are critical to effective project development and execution. Team leaders will be assigned to manage each phase directly. The team leaders will draw upon their own staffs and other staff of ConEdison Solutions. Further, ConEdison Solutions will continue to ensure 1) creativity in identifying energy conservation measures, 2) consistency in analytic tools and techniques, and 3) quality of our technical activities. 3 3 3 3 3 3 3 3 3 3 SITE MANAGEMENT APPROACH Implementation Management Approach City of Northampton ESPC February 16, 2010 ConEdison Solutions 4-3 Proprietary and Confidential Key Construction Staff for Northampton ESPC Project Director, National Accounts – Principal-in-Charge Ken Nathanson Senior Project Developer John Johnson Sr. Energy Efficiency Engineer – Project Development Steve Manwell Sr. Energy Efficiency Engineer – Mechanical Projects Ray Biszko Manager, Commissioning – Energy Management Systems Kevin Venturini Manager, Implementation – Construction Management and Measurement and Verification Louq Tidjani • Construction and Implementation Team.

Coordination of the Cx team activities will be the responsibility of the Manager of Cx. The Cx team may use equipment vendors and/or subcontractors to perform some start-up and testing procedures in order to maintain the project schedule. The role of the vendors and/or subcontractors in the Cx process is generally limited unless otherwise specified during the procurement process. In cases where vendors and/or subcontractors are used, their work and progress will be monitored and confirmed by the Manager of Cx or members of the Cx Team. Representatives from the facility operations staff are encouraged to participate in Cx activities whenever possible. 3 3 3 3 3 3 3 3 3 3 SITE MANAGEMENT APPROACH Implementation Management Approach City of Northampton ESPC February 16, 2010 ConEdison Solutions 4-8 Proprietary and Confidential • Procedure: While the specific procedure varies depending on the type of ECM equipment and applications involved, the basic elements are the same: Installation Check-out, Pre-functional Testing, Functional Testing, and in some cases Global Functional Testing. During the construction phase of the project, ConEdison Solutions will prepare a Cx plan for review by facility representatives. The plan will outline the scope of work, objectives, organization, schedule, documentation requirements, and testing procedures that will be used to commission each ECM. The Cx plan will detail the procedures to verify and document proper ECM equipment performance as described below. Functional Testing and Global Functional Testing procedures may be performed on a representative sample basis where identical systems are installed. Cx for ECM equipment will include at least two (2) of the procedures below and in some cases they will include all four (4) procedures. The facility personnel are welcome and encouraged to participate in any or all phases of the Cx process below. 1. Installation Check-out Procedure: In preparation for Pre-functional Testing, a review of the ECM installation specification and the equipment manufacturer’s installation documents is completed to determine that the ECM equipment has been installed properly. If the equipment installation is in compliance with the documents, Cx proceeds to the next phase. If not, corrective action is taken and the process is repeated. 2. Pre-functional Testing Procedure: After the Installation Check-out has been completed, the Project Manager/Cx Agent will witness and in some cases perform the Pre-functional testing on a representative sample basis to ensure that the manufacturers recommended start-up procedures are being performed properly. The Pre-functional Test forms will include at a minimum the manufacturer’s equipment start-up forms. The goal of Pre-functional testing is to confirm that equipment has been installed properly and is ready to be placed into service. In some cases this testing may involve temporary operation and performance testing over a period of time sufficient to confirm conformance to project specifications and manufacturer’s guidelines. 3. Functional Testing Procedure: After the Pre-functional Testing has been completed, the ECM equipment will be placed into operational duty and the Project Manager/Cx Agent will witness, participate in, and in some cases perform the Functional Testing. Functional Tests Procedure forms will be created by the Manager of Cx, Project Manager, or Cx Agent specifically for the ECM equipment being tested. 4. Global Functional Testing Procedure: After the Functional Testing has been completed it may be necessary to perform Global Functional Testing for ECM equipment installed. An example of this would be HVAC equipment that has 3 3 3 3 3 3 3 3 3 3 SITE MANAGEMENT APPROACH Implementation Management Approach City of Northampton ESPC February 16, 2010 ConEdison Solutions 4-9 Proprietary and Confidential an Energy Management System (EMS) controlling or interacting with them. In this example the Project Manager/Cx Agent will witness, participate in, and in some cases perform the Global Functional Testing on the HVAC and EMS equipment. This procedure will ensure that the individual components and all components as a group are performing properly, as designed, and as specified in the contract documents. 4.3.3 Retro-Commissioning Procedures Introduction Retro-commissioning (RCx) applies a systematic investigation process for improving and optimizing a building’s operation and maintenance (O&M). In most cases RCx occurs well after construction has finished and as an independent process. RCx is typically applied to buildings that have not previously been commissioned and are suffering from some form of deferred maintenance. It is a systematic process intended not only to optimize how equipment and systems operate, but also to optimize how the systems function together to improve occupant comfort and increase energy savings. Although RCx may result in recommendations to investigate further capital improvements, O&M tune-up activities and diagnostic testing are primarily used to optimize the building systems. The goals and objectives for applying the process, as well as the level of rigor, may vary, depending on the current needs of the owner, and the condition of the equipment. The RCx process will most often focus on the dynamic energy-using systems with the goal of reducing energy waste, obtaining energy cost savings for the owner, and identifying existing problems. Understanding how energy is used in a particular building is an important first step towards ensuring that we apply the proper building specific energy saving RCx measures. As part of our comprehensive approach to energy conservation and in particular this RCx procedure, ConEdison Solutions will observe review the building’s present controls systems and strategies in an attempt to find cost effective non capital improvements that can be implemented with minimal cost. It may also include investigating and proposing capital improvements especially any energy efficient capital improvement measures that are found. All capital improvement measures thought to be cost effective will be offered as recommendations to the owner. The steps for completing the RCx process are outlined below. Most if not all of these steps will be followed as part of the comprehensive RCx that will be provided by the ConEdison Solutions Cx Team. Step 1. Site Assessment 3 3 3 3 3 3 3 3 3 3 SITE MANAGEMENT APPROACH Implementation Management Approach City of Northampton ESPC February 16, 2010 ConEdison Solutions 4-10 Proprietary and Confidential The site assessment starts with a kick-off meeting where all parties meet to go over the overall commissioning plan, the Initial Site Assessment Procedures and the schedule. During this assessment ConEdison Solutions’ Commissioning (Cx) Agent will develop an in-depth understanding of how and why the building systems and equipment are currently operated and maintained and how that might be improved. This is accomplished by interviewing the facility Operations and Maintenance staff and by making site inspections of all primary energy using equipment. Problems and improvements are identified by gaining information from facility staff, equipment vendors, the control system and written documentation. Control sequences, setpoints, control parameters and schedules are also closely examined as part of this process. Actual equipment testing is not performed during this initial assessment. A list of improvements will be generated from the assessment prior to any monitoring or functional testing. The information coming from the assessment will also identify areas where formal monitoring and testing will be most beneficial to identify further operational improvements. Our assessment will typically consist of the following: a) Developing an understanding of the building equipment and systems b) Identifying the largest energy using equipment and analyze utility bills for larger buildings c) Identifying the known most problematic control, operational and comfort problems d) Identifying the design and operational intent and control sequences e) Identifying opportunities to reduce unnecessary runtime and unnecessary capacity levels f) Identifying changes to control parameters, strategies, set points, sequences or needed maintenance that will optimize efficiency, comfort, operation and control g) Documenting noticed problems of equipment condition (broken dampers, dirty coils, sensor calibration, etc.) h) Identifying missing documentation of control sequences i) Identifying any obvious upgrades to equipment that may be cost-effective Step 2. Functional Testing Plan The Functional Testing plan provides a list of the equipment and components that are initially intended to be tested, the general modes and functions that will be tested, and expected sampling strategies. ConEdison Solutions’ Cx Agent revises this table to represent the current focus of the project after consulting with the Facility Manager. The initial intent is to perform most of the diagnostic work using the existing EMS and its trending capabilities. a) As determined from the Initial Site Assessment and from the analysis of the monitoring data, equipment will be selected for Functional Testing through various modes of operation. Functional Test procedure forms will be developed describing each 3 3 3 3 3 3 3 3 3 3 SITE MANAGEMENT APPROACH Implementation Management Approach City of Northampton ESPC February 16, 2010 ConEdison Solutions 4-11 Proprietary and Confidential procedure. These procedure forms will direct the testing and be used to document the results. b) ConEdison Solutions’ Cx Agent oversees and conducts Functional Tests on selected equipment, with the assistance of Facility Staff, Controls Vendor, or Mechanical Contractor as needed. Functional Tests will be comprised of changing parameters, setpoints or conditions and observing and documenting the system or equipment response through various modes and conditions. For equipment that is being monitored by the required EMS points, Functional Testing may be accomplished by changing the parameters during the monitored period. The monitored data is then examined and used to document and verify correct or incorrect operation. Once the data is gathered from the monitoring and testing, ConEdison Solutions’ Cx Agent analyzes the findings. Deficiencies are documented and suggested improvements are provided to the Facility Manager. The list of improvement opportunities is prioritized by the Facility Manager and the ConEdison Solutions’ Cx Agent. Step 3. Implement O&M Improvements ConEdison Solutions’ Cx Agent along with any necessary contractor staff will correct the deficiencies identified in accordance with the RCx responsibilities written in the performance contract between the ESCO and Customer. RCx Covered Equipment and Costs Where noted, ConEdison Solutions has allocated an allowance type cost to RCx and replace pneumatic/electronic devices, and control components such as thermostats, sensors, and actuators. The price allocation associated with the RCx work is based on an estimated failure rate of and unit costs for materials and labor, and is only an estimate for the repair or replacement of failed components. 4.4 OPERATION AND MAINTENANCE OVERSIGHT Proper operation and maintenance of the energy systems at the City of Northampton facilities will help ensure that the project benefits are achieved. ConEdison Solutions will develop an O&M plan designed to keep ECM equipment at maximum efficiency. Our plan will provide City of Northampton with complete and organized equipment operation and maintenance (O&M) manuals, including a summary O&M manual that provides a quick reference to the main pieces of equipment and their proper operation and preventative maintenance requirements. Preparation of these documents will be closely coordinated with the City of Northampton Engineering Division staff. These preventative maintenance activities, along with the new equipment being installed by this ESPC contract, will result in lower maintenance costs overall to City of Northampton. 3 3 3 3 3 3 3 3 3 3 SITE MANAGEMENT APPROACH Implementation Management Approach City of Northampton ESPC February 16, 2010 ConEdison Solutions 4-12 Proprietary and Confidential ConEdison Solutions’ annual O&M costs assume that four (4) site visits per year will be made during each of the first three years of the performance period to evaluate the condition of the ESPC upgrades and assure compliance with the recommended maintenance, repair, and correct operation of the equipment installed. Subsequently, there will be two (2) such site visits per year for the next two years, then one (1) site visit per year for the remaining performance period years. ConEdison Solutions will report all observed O&M deficiencies to the City of Northampton as soon as they are discovered to minimize any loss in equipment operating efficiency. 4.5 ECM TRAINING To ensure that prudent and efficient systems operations are well documented, ConEdison Solutions will provide training materials and instructional sessions to appropriate staff and contractors. Our training efforts, which will address systems and equipment that we install, modify, or influence through our ECMs, are built on three core elements: 1. Ongoing Communication and Involvement. Effective communications and involvement with the people and organizations that ultimately will be responsible for operating the systems at the agency are part of the training process. By involving staff and subcontractors early in the process, we can ensure that they are ready, willing, and able to operate the systems as designed. 2. Documentation and Manuals. Proper documentation also plays a critical role in the successful training. Long term success of the operations will be enhanced with guidelines, guidebooks and operating manuals upon which the staff and subcontractors can rely. The manuals will describe the rationale behind the measures introduced. The manuals will also specify operating parameters and procedures to be maintained for optimal savings, O&M requirements, name and contact of O&M vendor (where applicable), measurements to be made to ascertain operating efficiency and frequency of measurements, start up and shut down procedures, a detailed listing of equipment specifications, make and model numbers. A complete set of manuals from equipment manufacturers will be provided. 3. Hands-on Training Sessions. ConEdison Solutions will provide training sessions post commissioning to assure City of Northampton staff has a thorough understanding of O&M issues. In addition, we will organize operations demonstrations as appropriate, to provide as much meaningful experience to the maintenance and operations staff as possible. 3 3 3 3 3 3 3 3 3 3 SITE MANAGEMENT APPROACH Implementation Management Approach City of Northampton ESPC February 16, 2010 ConEdison Solutions 4-13 Proprietary and Confidential 4.6 ENERGY AND MAINTENANCE SAVINGS VERIFICATION Energy and Related Operations & Maintenance Savings Proposed Detailed energy savings calculations are contained in Appendix A. Since all proposed upgrades have a number of energy-saving elements and interact with other building energy measures, savings have been calculated using calibrated simulation models, which simultaneously calculate the effects of all these components. Savings aspects that will be evaluated in the simulation models include: - HVAC and EMCS Measures - Heating and Cooling Upgrade Measures - Lighting and Lighting Controls Measures - Office Equipment/Plug Loads - Building Shell Measures All key parameters contributing to savings have been explicitly identified in Appendix A’s building simulation models and the specific measurement and verification protocols have been identified for each of these parameters. If deviations from the specified parameters occur, the M&V plan will identify in a written report those deviations and identify clearly the party responsible for correcting such deviations. Those deviations under the control and management of CES will be corrected as soon as they are identified (typically during CES’s O&M oversight activities, but sometimes only after completion of CES’s annual M&V activities), and, if such deviations cannot be corrected, savings will be recalculated using the agreed-upon building simulation models to recalculate interactive energy savings for the building. Those deviations under the control of City of Northampton will be identified as soon as practicable and corrective actions recommended for City of Northampton to take. The City of Northampton will be responsible for any savings shortfalls associated with deviations under its control, and, for purposes of calculating energy savings, the agreed-upon building simulation model will be run with those deviations set to the values agreed-upon by the parties upon execution of the ESPC contract. Operating and Maintenance Savings Facility operations and maintenance (O&M) activities are currently performed by City of Northampton personnel and limited outside contracts. Most of the changes associated with the implementation of the ECMs identified herein will result in lower maintenance costs overall, either from reduced O&M labor requirements which allow limited O&M staff resources to focus on other facility needs, or from reduced materials purchases requirements, through new, (warranteed) equipment, and the avoided costs to replace end of life and problem equipment. These savings can be very significant but have not been quantified or included in this proposal. City of Northampton personnel will perform all routine, scheduled, and non-scheduled 3 3 3 3 3 3 3 3 3 3 SITE MANAGEMENT APPROACH Implementation Management Approach City of Northampton ESPC February 16, 2010 ConEdison Solutions 4-14 Proprietary and Confidential maintenance, repair, and replacement of equipment installed under this Delivery Order Proposal. The costs of such maintenance activities are stipulated to be less than or equal to the maintenance savings from installing new equipment in all cases. 5 RISKS AND RESPONSIBILITIES February 16, 2010 ConEdison Solutions 4-1 Proprietary and Confidential 3 SITE MANAGEMENT APPROACH 5.1 ESPC CONTRACT RISK AND RESPONSIBILITY MATRIX ConEdison Solutions price and its calculation of savings is predicated upon the conditions set forth in the following Contract Risk and Responsibility Matrix. RESPONSIBILITY/DESCRIPTION CES’s PROPOSED APPROACH Financial: Interest rates: Neither the CES nor the City of Northampton has significant control over prevailing interest rates. During all phases of the project, interest rates will change with market conditions. Higher interest rates will increase project cost, financing/project term, or both. The timing of the Delivery Order signing may impact the available interest rate and project cost. Clarify when the interest rate is locked in, and if it is a fixed or variable rate. Fix interest rates at time of signing Delivery Order. (CES to prepare deal sheet to attract bids from finance companies.) RESPONSIBILITY/DESCRIPTION CES’s PROPOSED APPROACH Energy prices: Neither the CES nor the City of Northampton has significant control over actual energy prices. For calculating savings, the value of the saved energy may either be constant, change at a fixed inflation rate, or float with market conditions. If the value changes with the market, falling energy prices place the CES at risk of failing to meet cost savings guarantees. If energy prices rise, there is a small risk to the City of Northampton that energy saving goals might not be met while the financial goals are. If the value of saved energy is fixed (either constant or escalated), the City of Northampton risks making payments in excess of actual energy cost savings. Stipulate all energy prices at time of contract signing based on agreed energy price projection rates and FY2009 baseline energy prices. 3 3 3 3 3 3 3 3 3 3 SITE MANAGEMENT APPROACH Risks and Responsibilities City of Northampton ESPC February 16, 2010 ConEdison Solutions 4-2 Proprietary and Confidential RESPONSIBILITY/DESCRIPTION CES’s PROPOSED APPROACH Construction costs: The CES is responsible for determining construction costs and defining a budget. In a fixed-price design/build contract, the City of Northampton assumes little responsibility for cost overruns. However, if construction estimates are significantly greater than originally assumed, the CES may find that the project or measure is no longer viable and drop it. In any design/build contract, the City of Northampton loses some design control. Clarify design standards and the design approval process (including changes) and how costs will be reviewed. CES is responsible for constructing the project for the stated construction budget amount, subject to changes in scope agreed upon between CES and City of Northampton. Notable exceptions to this would include acts outside of CES control such as delays imposed by the City of Northampton or undisclosed hazardous material abatement requirements. M & V costs: The City of Northampton assumes the financial responsibility for M & V costs directly or through the CES. If the City of Northampton wishes to reduce M & V cost, it may do so by accepting less rigorous M & V activities with more uncertainty in the savings estimates. Clarify what performance is being guaranteed (equipment performance, operational factors, energy cost savings) and that the M & V plan is detailed enough to satisfactorily verify it. To maximize cost-effectiveness of M&V services, stipulate key parameters of most projects with limited measurement of a sample of loads; require annual M&V services throughout contract term for certain parameters for the more complicated projects; use an approved annual calibrated energy simulation program to calculate savings Delays: Both the CES and the City of Northampton can cause delays. Failure to implement a viable project in a timely manner costs the City of Northampton in the form of lost savings, and can add cost to the project. Clarify schedule and how delays will be handled. Establish a reasonable schedule and use best efforts to achieve schedule, but do not penalize delays. Major changes in facility: The City of controls major changes in facility use, including closure. Clarify responsibilities in the event of a premature facility closure, loss of funding, or other major change. City of Northampton takes on all responsibility for changes in use of facilities, including reduction in use and closure 3 3 3 3 3 3 3 3 3 3 SITE MANAGEMENT APPROACH Risks and Responsibilities City of Northampton ESPC February 16, 2010 ConEdison Solutions 4-3 Proprietary and Confidential RESPONSIBILITY/DESCRIPTION CES’s PROPOSED APPROACH Operational: Operating hours: The City of Northampton generally has control over the operating hours. Increases and decreases in operating hours can show up as increases or decreases in "savings" depending on the M & V method (e.g. operating hours times, improved efficiency of equipment vs. whole building, utility analysis). Clarify if operating hours are to be measured or stipulated and what the impact will be if they change. If the equipment loads are stipulated, the baseline should be carefully documented and agreed to by both parties. City of Northampton takes risks of changes in operating hours and equipment schedules and agrees to use throughout the contract term the building and equipment operating hours stipulated in the CES’s energy analysis models Load: Equipment loads can change over time. The City of Northampton generally has control over hours of operation, conditioned floor area, intensity of use (e.g. changes in occupancy or level of automation). Changes in load can show up as increases or decreases in "savings" depending on the M & V method. Clarify if equipment loads are to be measured or stipulated and what the impact will be if they change. If the equipment loads are stipulated, the baseline should be carefully documented and agreed to by both parties. Stipulate typical operating load profile based on measurements and/or calibrated annual simulation models Weather: A number of energy efficiency measures are affected by weather. Neither the CES nor the City of Northampton has control over the weather. Changes in weather can increase or decrease "savings" depending on the M & V method (e.g. equipment run hours times efficiency improvement vs. whole building utility analysis), If weather is "normalized" actual savings could be less than payments for a given year, but will "average out" over the long run. Weather corrections to the baseline or ongoing performance should be clearly specified and understood. All savings are calculated based on stipulated 30-year average weather conditions without adjustment for actual weather conditions. 3 3 3 3 3 3 3 3 3 3 SITE MANAGEMENT APPROACH Risks and Responsibilities City of Northampton ESPC February 16, 2010 ConEdison Solutions 4-4 Proprietary and Confidential RESPONSIBILITY/DESCRIPTION CES’s PROPOSED APPROACH User participation: Many energy conservation measures require user participation to generate savings (e.g. control settings). The savings can be variable and the CES may be unwilling to invest in these measures. Clarify what degree of user participation is needed and utilize monitoring and training to mitigate risk. If performance is stipulated, document and review assumptions carefully and consider M & V to confirm the capacity to save (e.g. confirm that the controls are functional). CES and City of Northampton arrive at an agreed-upon set of operating conditions and setpoints for all projects; CES uses these stipulations to determine savings throughout contract; CES annually verifies only the functionality and capability of the systems to achieve the stipulated setpoints and conditions. Performance: Equipment performance: Generally the CES has control over the selection of equipment and is responsible for its proper installation and performance. Generally the CES has responsibility to demonstrate that the new improvements meet expected performance levels including standards of service and efficiency. Clarify who is responsible for initial and long-term performance, how it will be verified, and what will be done if performance does not meet expectations. CES has full equipment performance verification responsibility throughout contract term; selected equipment is metered during annual cleaning and tune- up. CES will notify City of Northampton of any degradation in equipment efficiency and City of Northampton agrees to repair such equipment until it meets the operating efficiency measured in the initial M&V period. Operations: Responsibility for operations is negotiable, and it can impact performance. Clarify how proper operation will be assured. Clarify responsibility for operations and implication of equipment control. City of Northampton performs all operation of installed equipment; CES provides training, operations manuals, and periodic verification of optimal operation of equipment. Maintenance & Repair: Responsibility for maintenance and repair is negotiable; however it is often tied to performance. Clarify how long-term maintenance and repair will be assured, especially if the party responsible for long-term performance is not responsible for maintenance. Clarify who is responsible for ECM overhaul, component or equipment repair required to maintain operational performance throughout the contract term. CES provides only annual maintenance for measures requiring specialized skills or representing undue added responsibility to existing building maintenance providers; City of Northampton negotiates any additional routine maintenance scope of work with existing staff or maintenance contractors at nominal or no increase in cost to City of Northampton. 3 3 3 3 3 3 3 3 3 3 SITE MANAGEMENT APPROACH Risks and Responsibilities City of Northampton ESPC February 16, 2010 ConEdison Solutions 4-5 Proprietary and Confidential RESPONSIBILITY/DESCRIPTION CES’s PROPOSED APPROACH Equipment Replacement: Responsibility for replacement of contractor-installed equipment is negotiable; however it is often tied to ECM performance. Clarify who is responsible for replacement of failed components or equipment throughout the term of the contract. Specifically address potential impacts on performance due to equipment failure. Life of equipment is critical to ECM performance during the contract term. Specify equipment life expected for all installed equipment and specify warranties proposed for the installed ECMs. After warranty expires, City of Northampton will be responsible for replacement of failed equipment (other than failures caused by CES’s negligence) at its own expense 5.2 ASSUMPTIONS AND CLARIFICATIONS PROJECT SCHEDULE ASSUMPTIONS The preliminary schedule proposed in Appendix __ (or contained within this proposal) is predicated on the following assumptions: • Owner shall ensure coordination and access to the site and provide assistance in obtaining badges, if required, to all parties related to the project. • Owner shall designate an individual authorized to resolve questions, conflicts and coordinate activities. • Owner shall provide ConEdison Solutions with documents and shall answer any other reasonable request for information in a timely manner.
