In May 2024, the US Departments of Agriculture (USDA) and Housing and Urban Development (HUD) updated minimum energy standards for new construction, requiring new covered buildings under four stories to comply with the 2021 International Energy Conservation Code (2021 IECC) and taller buildings to meet ASHRAE/ANSI Standard 90.1-2019.
