On behalf of 22 consumer protection, housing affordability, energy efficiency, and climate justice signatory organizations, we thank you for your continued work to secure healthy, affordable, and efficient housing for all residents. We write today to reinforce our support and excitement for the final determination from the Department of Housing and Urban Development (HUD) and the Department of Agriculture (USDA) on the adoption of updated energy efficiency standards for new construction of HUD- and USDA-assisted housing. Increasing energy efficiency will improve housing affordability, generating significant cost-savings for low-income households and positively contributing to the economy. HUD analysis also shows that actions to improve energy efficiency would not significantly impact housing availability. We urge you to expeditiously finalize the determination and move forward with implementation.
