Energy codes set the minimum standard for the energy efficiency of buildings to ensure that homes and commercial buildings reduce their energy use, lower utility bills and improve occupant comfort.

Energy codes address wall and ceiling insulation, window and door specifications, HVAC and ventilation equipment efficiency, and lighting fixtures, among other building features.

As the State Energy Office and recipient of the SEP funding the Division of Energy is engaged in building code efforts. These efforts include research on the current status of code adoption in Missouri, research on the costs and benefits of the codes, outreach to municipalities, efforts to increase knowledge and adoption of the codes and coordination with DOE and the regional code networks such as Midwest Energy Efficiency Alliance.
