New White Paper Highlights Energy Codes and Efficiency


Housing Affordability Institute released a new white paper today outlining energy codes and the efficiency of new homes built in the United States. Energy codes are model building codes that establish the minimum energy efficiency standard for structures.

Highlights:

  • Homebuilders can follow an energy code’s prescriptive path or choose one of three performance-based paths.
  • New homes built in the United States in 2023 were on average 47% more efficient than a typical home built in 2006.
  • Roughly 82.77% of the nation’s housing stock was built before 2006. This large portion of the nation’s housing stock is 30% more inefficient than homes built in 2006.

Energy Codes and New Home Efficiency is the latest white paper in Housing Affordability Institute’s Housing Policy Explainer Series.
