Energy Star 3.2 Cranks Up Envelope Efficiency

The U.S. Environmental Protection Agency recently finalized the requirements for the latest version of its long-running ENERGY STAR Single Family New Home program. The National Version 3.2 puts the thermal envelope requirements of the 2021 International Energy Conservation code front and center. The new version now stipulates mandatory envelope requirements of the 2021 IECC. It ensures a minimum of 10 percent savings over the current requirements of the 2012 IECC and a 20 percent improvement or more in states where older versions of the code are enforced. The new program changes will take effect beginning January 1, 2025. However, when version 3.2 is released this fall, it will be useable with a thermal envelope 5 percent worse than the 2021 IECC (105% UA of 2021 IECC).

The $32M DOE Effort to Boost EE

Long-needed energy efficiency improvements in much of America’s public housing means that low-income tenants spend a significant portion of their income on energy costs. Moreover, buildings are the second-largest carbon dioxide emissions source. The U.S. Department of Energy (DOE) seeks to address this by launching an experiment with architects and public housing agencies to retrofit these homes with heat pumps and insulation upgrades to improve their efficiency.

Decarbonizing Buildings Starts with Energy Efficiency

Responsible for nearly 40 percent of global climate emissions, buildings are critical to the government’s response to climate change. As lawmakers and climate advocates look for new policies that will curb greenhouse gas emissions from the built environment, the old rallying cry for energy efficiency is being replaced by calls for policies that drive building decarbonization. This leads to the question, just where does energy efficiency fit in this broader goal of decarbonization?
