PIER Demonstration ProgramENERGY EFFICIENCY OPPORTUNITIES
CALIFORNIA
Overall Approach
1. Energy efficiency comes 1st first in the loading order
2. Work with utilities to develop technologies strategically
3. In partnership, conduct field demonstrations of promising new technologies
4. Move the research results forward in affiliation with others who share interest in energy efficiency

General Lessons Learned
• Work closely with contractors – Installation…beware of unique building conditions and/or
campus standards– Labor estimates…technology education reduces cost
• Work closely with manufacturers– Installation and commissioning assistance – Product improvement through reiterative design process
fueled by lessons from the demonstrations
• Do demonstrations with forward-thinking owners– Leverage results beyond one-off jobs– Included in IOU Applications– Stimulate campus standard improvements
Overall Results/Status
• Case studies for each technology (CIEE and CLTC websites)• Key results
– Group-buy in discussion for bi-level stairwell fixture– Established interest in ICLS, smart vanity, exterior hybrid– Improved campus standards (PIER Product Specifications)
• Results assisting in refining technologies• Plans for next round — 3 yrs starting Spring ‘07
– Continue at UC/CSU– Expand into other areas (housing, food svc, etc.)– Expand into California Dept. of General Services– Expand into Community College System
