Why is disclosure important? 15 Allows markets to work by providing energy information at the time of transaction Encourages markets to value and reward energy efficient buildings and make buyers aware of under- performing buildings Encourages improving the energy efficiency of low- performing homes by focusing attention on energy performance Will help Vermont meet its goal of improving 80,000 homes by 2020 Save energy and create jobs

Building Energy Labeling Cycle 16 + Bill savings + Green jobs – CO 2 emissions

Success Story: Australia 17 “The study looked at whether a relationship exists between the EER of a house and sale price using data from 2005 and 2006 and found that a statistically significant relationship does exist. This means, if a house has a higher EER than another house, but in all other respects the houses are the same, the house with the higher EER will command a higher price.” “EER was found to be positively associated with house price. The association on average for 2005 was 1.23 percent for each 0.5 EER star and 1.91 percent in 2006, holding all other variables constant.” (0-10 EE Rating) E.g. for a $200,000 home,.5 EER adds ~$3,000 in value
18
Recommendations on H.57 18 1. I strongly support (EFG and BSR) This can be an effective tool to move retrofit markets Leaving the tool specifics and rater certification to rule-making is a good approach 2. Clarify some of the language Don’t use the term “audit” Use “rating”, “label” or “score” 3. Don’t require energy improvement recommendations Too expensive and lack of standard approach Let BPI contractors offer as a value-added service
19
Recommendations, con’t 19 4. Provide guidance to rule-making to balance the time, accuracy and cost in deciding on a rating tool (e.g., < 2 hrs) 5. Given the lack of energy code compliance in VT, consider including code documentation for new buildings as part of this
