Northwest Power and Conservation Council slide 8 Long-life Fluorescent Lighting Key to long life: T5s with program-start ballasts Key to long life: T5s with program-start ballasts Philips and Sylvania lamps: 46,000 hours Philips and Sylvania lamps: 46,000 hours Kumho Electric: 100,000 hrs! Kumho Electric: 100,000 hrs! Work well with occupancy sensors Work well with occupancy sensors

Northwest Power and Conservation Council slide 9 Why do we care? Lower implementation and maintenance costs Lower implementation and maintenance costs Now competes with SSLs for longevity Now competes with SSLs for longevity Less embodied energy Less embodied energy

Northwest Power and Conservation Council slide 10 Downsides of LED Lighting for General Service Lighting “100,000 hours” is only for colored lights “100,000 hours” is only for colored lights “White” lights are still not consistent color “White” lights are still not consistent color Currently very expensive Currently very expensive Difficult to achieve even light distribution Difficult to achieve even light distribution

Northwest Power and Conservation Council slide 11 Low-Lift Cooling 1 of 5 “Technology Option Sets” to be developed by the DOE net Zero Energy Buildings program by of 5 “Technology Option Sets” to be developed by the DOE net Zero Energy Buildings program by 2010 A package of five technologies that work together as a system A package of five technologies that work together as a system According to PNNL models: save 30-74% of cooling in new buildings According to PNNL models: save 30-74% of cooling in new buildings BPA to be doing field trials BPA to be doing field trials

Northwest Power and Conservation Council slide 12 Low-Lift Cooling Option Set 1. Peak-load shifting by thermal energy storage 2. Dedicated outdoor air supply with enthalpy heat recovery from exhaust air 3. Radiant heating/cooling system: panels or floor 4. Low-lift vapor compression cooling equipment 5. Advanced controls at equipment and system (supervisory) levels

Northwest Power and Conservation Council slide 13 Business Practices Not Technologies Not Technologies Strategies that: Strategies that: –Create new savings due to synergies –Allow higher penetration of measures –Improve persistence of measures Significant new conservation potential Significant new conservation potential
