The U.S. Department of Housing and Urban Development (HUD) has updated its Minimum Energy Standards (MES) to adopt the 2021 International Energy Conservation Code (IECC) and ASHRAE Standard 90.1-2019. These updates affect new housing construction and rehabilitation projects funded by HUD and the U.S. Department of Agriculture (USDA). The new energy codes aim to reduce energy consumption, lower costs, and improve climate resilience in residential buildings.
The updates will come into effect in 2025. They offer phased compliance deadlines, especially for rural areas with persistent poverty. This ensures that builders and developers have time to adjust to the more stringent requirements. Programs affected include HUD’s HOME Investment Partnerships Program, Section 202, Section 811, and USDA's Multifamily Housing programs, among others.
Key goals of the updated standards are to improve energy efficiency, reduce carbon footprints, and enhance the overall comfort and affordability of housing. By adopting these modern standards, HUD seeks to advance the sustainability and energy performance of new and rehabilitated homes, in line with national climate goals.
In addition to energy savings, the updates are expected to contribute to reducing greenhouse gas emissions, making homes more resilient to climate-related stresses such as extreme heat and cold. The enhanced standards also aim to increase affordability for low-income families by lowering energy bills, ensuring that high-quality, energy-efficient housing is more accessible to all.
