   Factor from ''Calculating lighting and HVAC interactions,'' Table 1, ASHRAE Journal November 1993

   Commercial Lighting--Existing Buildings 1-Lamp Fluorescent Lighting Fixture (Office Building example)

Current typical existing lighting market (baseline) Standard T8 Lamp/Ballast System
Federal standard as of January 1, 2006 Energy Savings T12 (34 Watt) Lamps and Energy Efficient Magnetic Ballast
Minimum threshold for credit High Performance (Super) T8 Lamp/Low Power Ballast System
Estimated savings credit for installing High Performance (Super) T8 Lamp/Low Power Ballast System 28 kWh (per fixture)
Change in usage calculation1 ΔkWh = ((Wattsbase - Wattseffic)/1,000)
HOURS × WHF
Measure life 15 years
