CF = Demand Coincidence Factor (See Section 1.5) HOU = Hours of the average annual operating hours of the – baseline lighting equipment (before the lighting controls are in place), which if applied to full connected load will yield annual energy use. IF demand = Interactive HVAC Demand Factor applies to C&I interior – lighting in space that has air conditioning or refrigeration only. This represents the secondary demand savings in cooling required which results from decreased indoor lighting wattage. IF energy = Interactive HVAC Energy Factor applies to C&I interior – lighting in space that has air conditioning or refrigeration only. This represents the secondary energy savings in cooling required which results from decreased indoor lighting wattage. SVGEE = Savings factor for new lighting control (percent of time the lights are off). SVGbase = Savings factor for existing lighting control (percent of time the lights are off), typically manual switch. Baseline Assumptions The following are acceptable methods for determining baseline conditions when verification by direct inspection is not possible as may occur in a rebate program where customers submit an application and equipment receipts only after installing efficient lighting equipment, or for a retroactive project as allowed by Act 129. In order of preference: Examination of replaced lighting equipment that is still on site waiting to be recycled or otherwise disposed of. Examination of replacement lamp and ballast inventories where the customer has replacement equipment for the retrofitted fixtures in stock. The inventory must be under the control of the customer or agent. customer’s Interviews with and written statements from customers, facility managers, building engineers or others with firsthand knowledge about purchasing and operating practices at the affected site(s) identifying the lamp and ballast configuration(s) of the baseline condition.
