Forty-three states and most U.S. jurisdictions have adopted regulations for energy-efficient construction of commercial buildings. These regulations usually include provisions related to low-slope roof assemblies— buildings whose roofs slope less than two units vertical in 12 units horizontal (2:12). This course highlights commonly adopted energy-code provisions for commercial low-slope roof assembles and examines the process of how such provisions are adopted.

After reading this article, you should be able to:
+ UNDERSTAND model energy codes and code adoption processes and procedures.
+ DISCUSS key roofing-related provisions of the International Energy Conservation Code (IECC).
+ LIST several energy code considerations for reroofing projects.
+ DESCRIBE the advantages of developing relationships with local building code officials on energy code requirements.
