Abstract: Housing plays an important role in decreasing the overall U.S. energy consumption. To promote energy efficiency in the residential sector, utilities and governments are increasingly relying on incentives linked to “green certification” protocols. Programs like USGBC LEED®, Green Building Initiative’s (GBI) Green Globe or other recognized rating system account for many aspects of home energy use, but they fail to measure real energy consumption rates of buildings after certification.

This article presents data showing that in 2006, Florida’s first ENERGY STAR® homes are still more energy efficient than conventionally built homes, but not by as much as they were in 2000. These results can be viewed optimistically, but also clearly point to the need for credible energy consumption data on which to build practical policies to effectuate change.
