Performance Services added to the building, air-conditioning of areas that were previously not air-conditioned and other identified adjustments shall be added to Base Year energy costs. Performance Services does not utilize computer modeling to determine savings potential or a facilities baseline consumption usage as we find that the program is only as good as the assumptions made and the data entered. Instead, we use actual utility bills given to us by our customer to determine the baseline utility consumption. This gives a more accurate picture of what the facility is using. Performance Services intends to maximize the energy savings for your project primarily through careful consideration for the design of your solar facilities. We aim to deliver superior financial performance of your systems by developing designs that balance upfront costs with efficient and effective power generation. Below is a list of some of the items we evaluate to maximize value and energy savings for our customers: • Site location (distance to switchgear, shading, and topography considerations) • Panel selection (wattage, efficiency and cost considerations) • Inverter selection (size, stringing and cost considerations) • Panel angle (row spacing and production ratio considerations) • System commissioning for optimal performance • LED and other building efficiency impacts on kWh reduction and solar design Performance Services uses International Performance Measurement and Verification Protocol (IPMVP) for all our guarantees. Unlike other providers that only use Option C, The Whole Facility Method, Performance Services utilizes methods designed specifically for the improvement item selected. For example, according to the IPMVP manual, Option A is most effective for lighting retrofits. Option B is used for replacement of equipment that utilizes electricity and Option C (Whole Building) is excellent for gas energy savings i.e. comparing gas bills of the base year to gas bills of the post -retrofit period. The selection of the most optimal and cost-effective methodology for performance assurance will depend on the improvements selected by the City of South Bend. As part of the contract development process, Performance Services will work with the City to specify the exact monitoring necessary of program improvements and costs for each improvement option, including which should be stipulated because the cost of M & V outweighs the obvious calculated savings, Le, switching to LED lights gives an obvious reduction in kW usage that can be easily calculated. The sum of these will be used as the basis of the performance guarantee. For your project, we would recommend Option A which involves a one- time measurement of solar output. c.
