Time to Optimize Thermal Performance in 100M Homes

America has more than 100 million leaky homes that are prime for energy efficiency and electrification upgrades, including air sealing and insulation. Without serious engagement by utilities and contractors to address the issue of thermal leakage, the lofty goals the Biden Administration has set for carbon reduction and electrification will not be achieved, says Rick Barnett, a green builder and remodeling contractor. Barnett has been an advocate for thermal envelope efficiency and green building for more than 30 years.

DOE Updates ZERH Specs, Provides 45L Details

The U.S. Department of Energy (DOE) last month released the latest version of the Zero Energy Ready Home (ZERH) requirements for single-family homes. Version 2 of the ZERH requirements included an update of the thermal envelope insulation levels to those required by the 2021 Residential IECC, whereas the previous version (V1 Rev 8) stipulated 2015 IECC thermal insulation requirements.

Ekotrope Spots $160M Missed Opportunity for Builders

A new analysis from Ekotrope, the leading provider of home energy rating software, shows U.S. home builders might leave money on the table. Ekotrope software is used to generate energy efficiency insights for one in four U.S. homes. Its analysis concludes that if the homes built this year were slightly more energy efficient, builders could claim more than $160 million in projected tax credits under the Inflation Reduction Act’s (IRA) builder tax credit (45L).

Rule Your Attic Kicks Off Next Week

The U.S. Environmental Protection Agency’s (EPA) ENERGY STAR annual “Rule Your Attic” campaign kicks off on Monday, October 17. The annual campaign encourages homeowners to go into their attic, check their insulation levels, and air seal and insulate if needed. Most homes will need to add insulation as 9 out of 10 U.S. homes are under-insulated.

We Should Talk About Insulation More

“We need to think about insulation, or to start thinking about it in the first place,” says a Vox news story this week. As part of a series that addresses our warming world, Vox writer Neel Dhanesha calls insulation the climate solution hiding in our walls. There’s no time like today — Earth Day — to talk about insulation’s important role as a tool for pollution reduction.
