Updating building energy codes has long been a goal for advocates of efficient building practices. The past success in doing so has led to dramatically lower energy consumption for a building built today as compared to 30 years ago. However, we are currently in a period of dramatically diminished returns, not because building practices can't improve, but because the model code has stalled. The 2015 and 2018 versions of the residential model code offer improvements of less than 1% over the 2012 version. Yet time and effort are being spent to push states to always adopt the latest model code. The ACEEE scorecard gives significant credit to states that do so. This panel will focus on ways these efforts could effect more change, through stretch codes, amendments during the adoption process, and other avenues. It will also consider the positive and negative impacts of backing away from advocating for quick adoption of the latest model code.
