Northwest Power and Conservation Council slide 25 Increased achievable potential relative to 5th Plan Increased achievable potential relative to 5th Plan –Over 500 MWa in 6th versus about 350 MWa in 5th –New measures added exceed accomplishments –Lower achievable LPDs –More ways to turn lights off More in Natural Replacement than Retrofit More in Natural Replacement than Retrofit Somewhat higher cost Somewhat higher cost Not all of this is cost-effective Not all of this is cost-effective Low TRC cost Low TRC cost Preliminary Results for Interior Lighting

Northwest Power and Conservation Council slide 26 Notable Changes from 5 th plan T12 Linear Fluorescent are dying out T12 Linear Fluorescent are dying out –None in new buildings, phasing out in existing stock High Performance T8 (HPT8) is FL measure of choice High Performance T8 (HPT8) is FL measure of choice Replace 1990s T8s with HPT8 (75 to 95 lumens/Watt) Replace 1990s T8s with HPT8 (75 to 95 lumens/Watt) Programs should promote HPT8 ONLY Programs should promote HPT8 ONLY Baseline for incandescent is Halogen (EISA2007) Baseline for incandescent is Halogen (EISA2007) Baseline for Metal Halide is Pulse Start (EISA2007) Baseline for Metal Halide is Pulse Start (EISA2007) –Savings deltas are smaller Lot of CFLs in new buildings Lot of CFLs in new buildings Linear Fluorescent is replacing Metal Halide Linear Fluorescent is replacing Metal Halide –But MH to Linear FL still a good measure Added Efficient Fluorescent Fixtures as NEW MEASURE Added Efficient Fluorescent Fixtures as NEW MEASURE

Northwest Power and Conservation Council slide 29 How We Estimate Lighting Savings Lighting Energy: Watts x Hours = kWh Lighting Savings: Watts Saved x Hours = kWh Saved + HVAC Interaction or Watts x Hours Saved = kWh Saved + HVAC Interaction More Efficient Lamps & Ballasts More Efficient Fixtures Control Measures: Occupancy sensors, timers, day lighting

Northwest Power and Conservation Council slide 30 How We Estimate Cost of Savings First Cost = Equipment + Labor + Markup + Disposal Periodic Costs = Lamp replacement costs or savings Annual Fuel Costs = Cost of gas to replace heat from lights PROCOST COSTS SAVINGS SHAPE OF SAVINGS kWh $ / kWh

Northwest Power and Conservation Council slide 31 Then Supply Curves kWh/SF x (SF Applicable) x (Achievable) = Total Potential Simple …

Northwest Power and Conservation Council slide 32 But Tedious 10 proxy lighting measures, 18 building types, 3 fuel types, 3 applications = 1620 lighting measures 10 proxy lighting measures, 18 building types, 3 fuel types, 3 applications = 1620 lighting measures Each with a dozen different costs & savings inputs Each with a dozen different costs & savings inputs
