What Works Well
36
What Didn’t Work
• Increased Incentives no Guarantee of Increased Participation
• Goal Setting must be from market potential and not from Top Down approach
• Keep it Simple– Rebate process and rules have to be extremely easy to
understand and follow to get maximum participation• Advertising: One size doesn’t fit all
– Commercial customers require relationships to be established with customer and equipment vendors
• Gateway Communication 1998– Technology not ready and costly– Concept ahead of technology
• Residential Paid Audits– Additional time and information not accepted
• Load Control programs can grow too large a percent of reserves
37
Building Code Impacts
• 1990 Code change from SEER 10 demonstrates slow transition to hi-efficiency Heat Pumps: 7 years
• Record number of implementations in 2006 with less than 50% of that number expected in 2007
