The Most and Least Energy-Efficient States in 2023

WalletHub has released its annual survey of America’s most and least energy-efficient states. The personal finance site’s evaluation of residential energy efficiency notes that the average U.S. family spends at least $2,000 annually on utilities. Notably, the U.S. Department of Energy estimates that adopting energy-efficient measures (such as air sealing and adding additional insulation) in a home could reduce utility bills by 25 percent.

More Insulation Tied to Increased Habitability

How long would your home remain comfortable and habitable in the event of a power outage in this summer’s brutal heat? The answer might depend on how well insulated your home is, according to a new report released by the U.S. Department of Energy. Analysis from the report, Enhancing Resilience in Buildings Through Energy Efficiency, finds that homes built to meet or exceed the 2021 International Energy Conservation Code (IECC) extend the habitability of buildings by 120 percent during extreme cold and up to 140 percent during extreme heat.

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. DOE also highlighted the new tax credits available to builders through the 45L builder energy efficiency tax incentive.

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).
