DOE Issues Updated Model Energy Code Determination for Residential Buildings |
|
|
The U.S. Department of Energy (DOE) has issued a determination that the updated model energy code for residential buildings, the 2024 International Energy Conservation Code (IECC), will increase energy efficiency in residential buildings. DOE technical analysis, performed by Pacific Northwest National Laboratory (PNNL), estimates that buildings meeting the 2024 IECC would result in national site energy savings of 7.80%, source energy savings of 6.80%, and energy cost savings of 6.60%. This action represents DOE’s determination for the 2024 IECC as directed under the Energy Conservation and Production Act (ECPA), as amended. (42 USC 6833)
Supporting technical analysis, as well as previous model energy code determinations, are available at: www.energycodes.gov/determinations.
The U.S. Department of Energy provides technical assistance to states, municipalities and the design and construction industry supporting building energy codes. Modern building codes offer the latest technologies and cost-effective solutions, contributing to lower energy bills for homes and businesses and ensuring safe, efficient and affordable buildings.
