kWee = kW of post-retrofit or energy-efficient lighting system (LED) lighting per letter CF = Demand Coincidence Factor (See Section 1.5) HOU = Hours of Use IFdemand = 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. IFenergy = 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.
