DOE Energy Codes Infographics
DOE tracks and analyzes data related to the adoption and implementation of the latest model energy codes. The following maps and graphics provide additional context to improve understanding of energy codes across the country.
Estimated Model Energy Code Energy Use & Incremental First Cost
The Normalized Energy Use and Incremental First Cost graph outlines the estimated national average energy use reduction and incremental first costs in model energy codes from 2006 to the present.
FIELD ASSESSMENTS
DOE has developed research methods to support states in studying the implementation of their building energy codes. The objectives of field studies are to document typical design and construction practices and target areas for improvement through education and training initiatives. States are encouraged to conduct field studies every 3-5 years to validate the implementation of codes and other energy-efficiency programs, and benchmark technology trends in residential and commercial construction.
The Residential Energy Code Field Studies and Commercial Energy Code Field Studies maps highlight states that have conducted field studies in single-family, multifamily, or commercial buildings within the last decade. Although DOE funded many of these studies to demonstrate early success, states and jurisdictions have utilized DOE methodologies to fund and facilitate studies outside the DOE program.
