Siemens will utilize four basic approach options to measure and verify savings: Option A - Measured Capacity, Option B - Measured Consumption, Option C Main Meter Comparison, and Option D - Stipulated. a. Option A - Measured Capacity. This approach is intended for Facility Improvement Measures where a one-time measurement for specific equipment or systems instantaneous baseline energy use, and a one-time measurement for specific equipment or systems instantaneous post-implementation (Post) energy use can be measured. Baseline and Post energy consumption is calculated by multiplying the measured end use instantaneous capacity (i.e. – kW, Gal/hr, BTU/hr) by stipulated hours of operation for each mode of operation (i.e. – hours, week, month). The calculations for energy consumption will be defined in the Measurement and Verification Article 4 of this Exhibit C. The work sequence required for data collection, evaluation, and reporting will be defined in the Measurement and Verification article of this Exhibit C. b. Option B - Measured Consumption. This approach is intended for Facility Improvement Measures where continuous periodic measurements for specific equipment or systems baseline energy use, and continuous periodic measurements for that equipment or systems post-implementation (Post) energy use can be measured. The calculations for energy consumption will be defined in the Measurement and Verification Article 4 of this Exhibit C. Periodic inspections and consumption measurements of the equipment or systems will be necessary to verify the on-going efficient operation of the equipment and saving attainment. The predetermined schedule for data collection, evaluation, and reporting will be defined in the Measurement and Verification article of this Exhibit C. c. Option C - Main Meter Comparison. This approach is intended for measurements of the whole-facility or specific meter baseline energy use, and measurements of whole-facility or specific meter post-implementation (Post) energy use can be measured. The methodology to establish baseline and Post parameter identification, modeling approach and baseline or model adjustments will be defined in the Measurement and Verification Article 4 of this Exhibit C. Periodic inspections of baseline energy usage, operating practices, and facility and equipment, and meter measurements of the will be necessary to verify the on-going efficient operation of the equipment, systems, practices and facility, and saving attainment. The predetermined schedule for data collection, evaluation, and reporting will be defined in the Measurement and Verification article of this Exhibit C. d. d. Option D - Stipulated. This approach is intended for Facility Improvement Measures where the end use capacity or operational efficiency; demand, energy consumption or power level; or manufacturer’s measurements, industry standard efficiencies or operating hours are known in advance, and used in a calculation or analysis method that will stipulate the outcome. Both CLIENT and SIEMENS agree to the stipulated inputs and outcome(s) of the analysis methodology. Based on the established analytical methodology the savings stipulated will be achieved upon completion of the Facility Improvement Measures Work and that no further measurements or calculations will need to be performed.

Description: Lighting upgrades include conversion to energy efficient technologies including lamps, ballasts, and/or the installation of occupancy sensors, while maintaining or elevating to standard illumination levels. How M&V will be performed: A detailed description of specific equipment to be installed is contained in the lighting audit inventory spreadsheets. All existing fixtures were individually identified and counted during the audit except for a few rooms that were not accessible, which have very-low occupancy. The baseline wattage for each type of fixture is based on the “Utility Luminaire Wattage Table” used for lighting retrofit savings calculations. Each fixture is either retrofitted or replaced with a new, more efficient system, or left unchanged if already efficient. Energy savings were calculated based upon the number and types of fixtures affected, and on the lighting hours of operation. Table 7.3.1 (Article 7) shows the operating hours for each usage group. A one-time watt measurement will be conducted after the retrofit for a representative sample of lighting fixtures from the different usage groups to verify the circuit draw. For each line item on the lighting inventory list the following savings calculations will be performed: kWhexisting = (Qtyexisting * Wattsexisting) / 1000 * Hrs kWhretrofit = (Qtyretrofit * Wattsretrofit) / 1000 * Hrs Annual Cost Savings = (kWhexisting - kWhretrofit) * ERkWh Where Qtyexisting = Existing number of fixtures Wattsexisting = Existing wattage per fixture Hrs = Annual Operating Hours Qtyretrofit = Retrofit number of fixtures Wattsretrofit = Retrofit wattage per fixture ERkWh = Energy rate $/kWh Savings analysis for this measure is presented in Appendix A, and the guaranteed annual energy savings is 141,480 kWh.

Description: Install Temperature Controllers and indoor sensors at mentioned locations with the capability to program time/temperature settings and unoccupied schedule. Savings will come from reductions in heating fuel use. Parks and Recreation, and Highway Departments have heating through hydronic system. The heating system runs 24/7 throughout the winter, maintaining 72ºF by means of a wall thermostat. The outdated temperature controller will be upgraded to “Digital 7-Day programmable” temperature control. The unit will operate based on a control schedule presented in Table 4.3.1.1. Outside occupied hours, the unit will switch to unoccupied mode and cycle to maintain 65ºF winter space temperatures. How M&V will be performed: Spreadsheet calculations using generally accepted engineering practices were used to calculate energy savings for each of the control strategies described above. These calculations will be the basis for verifying energy savings. In order to ensure the FIM is operating as designed, SIEMENS will be responsible for the following:    Pre-Heating Season verification that the control strategies and functions are accurately programmed. Pre-Heating Season verification that the output points are properly controlling equipment Pre-Heating Season verification that the input points are reading properly Table 4.3.1.1 below identifies the occupancy schedules that are the basis for energy savings associated with this FIM. The CLIENT agrees that the areas are unoccupied per the schedules below, and that the systems can be reset to unoccupied conditions during these periods. SIEMENS will calculate and report to the CLIENT the effect any schedule changes have on the energy savings. The CLIENT will report to SIEMENS any changes made to the schedules contained in Table 4.3.1.1 within (5) working days of the said change.

Maintenance Savings from BFP Feed Pump Operation Description: The WWTP has two belt press filter processes located in the sludge facility. The 2.0-meter press was installed in 1994 and is used to dewater sludge for two 8-hour shifts per day, four days per week. Currently, the BFP Feed Pump can not deliver the proper flow (175 gpm) to maximize dewatering operations. After Belt Filter Press Feed Pump upgrade, it is intended that the system will be capable to treat the same amount of sludge during one normal shift. Calculations The calculations for the cost savings will consider the following assumptions:  Hours per shift = 8  Days per week = 4  Total operations hours per shift per year (T) = 1664 hrs  Normal Wage (NW) = $20 per hour  Shift Wage (SW) = $30 per hour The annual stipulated savings are defined in this contract as corresponding to the elimination of one extra shift per day due to second belt filter press in operation. Operation Cost Savings = OC 1 - OC 2 With: OC 1 = Existing Operation Cost = NW x T + SW x T OC 2 = Proposed Operation Cost = NW x T + SW x T Operation Cost Savings = $49,920 4.5.3 FIM 2: Infra Red Heating Facilities: Highway Department, Wastewater Treatment Plant Description: The highway departments consist in one building divided in two main areas: garages and offices. Offices have individual HVAC systems. Garages are heated by two different systems. The original garage has several gas fired unit heaters hanging from the ceiling. The new addition is heated by hot water unit heaters attached to the ceiling as well. Both systems: gas fired and hot water unit heaters (UH) transfer the heat to the air, using a fan. The hot air then is distributed to the space. Wastewater Treatment Plant garages have multiple hydronic unit heaters. A gas-fired infra-red heating system emulates the efficiency of the sun by generating radiant energy that is converted into heat when absorbed by objects it targets. Once the infra-red energy is absorbed by the floors, machinery, stock and people, it is then reradiated to warm the surrounding air. This method of heating, as opposed to filling a room with warm air (such as a forced air unit) allows the source of heat to begin at the floor level and not the ceiling. This makes it the most efficient and effective method to heat the garage spaces. Page 14 of 46 Siemens Building Technologies, Inc. All Measures Exhibit C – Performance Assurance Town of Orangetown Highway Department Calculations: The determination of the existing heating load for the highway department is obtained by standard billing regression analysis of energy usage versus heating degree-days in base 65 (i.e. degree-days calculated from a balance point of 65 ºF). The total heating load is then corrected to a normal year (30 year normal as defined by N.O.A.A.) The resulting chart is presented in Figure 4.5.3.1 below, and establishes the baseline heating energy use. The normalized annual heating energy use is 33,487 CCF. For this facility the energy for heating is supplied to two different areas: garages and offices. The garages use two independent systems: gas fired unit heaters (forced air); and hydronic unit heaters (forced air). The offices have an independent HVAC system. Natural gas consumption of the forced air heaters is calculated using an estimated system efficiency of 76%.
