Chapel Hill WISE created this policy to establish a standard procedure for corrective action and dismissal for contractors. The policy lists standards that contractors are expected to meet, and procedures that the program follows to review concerns, place contractors on probation, and dismiss those who are unable to resolve identified issues.

This study looks at evidence of capitalization of energy efficiency features in home prices using data from real estate multiple listing services (MLS) in three metropolitan areas: the Research Triangle region of North Carolina; Austin, Texas; and Portland, Oregon. These home listings include information on Energy Star certification and, in Portland and Austin, local green certifications. Our results suggest that Energy Star certification increases the sales prices of homes built between 1995 and 2006 but has no statistically significant effect on sales prices for newer homes.
