The 2012 International Energy Conservation Code contains 396 separate requirements applicable to non-residential buildings; however, there is no systematic analysis of the energy cost impact of each requirement. Consequently, with limited building department resources, the efforts for plan review, inspection, and training may not be focused on the most impactful items. An inventory and ranking...

The last two decades have seen a tremendous increase in the stringency of California’s building energy efficiency code, Title 24 Part 6. Along with these changes, the complexity of the code has increased dramatically, as different design options for building envelope, heating, ventilating and air conditioning (HVAC) and lighting systems have become available under prescriptive...

Improvements in building energy codes cannot be fully realized unless targeted stakeholder education, training and outreach is provided to support increased understanding of and compliance with the minimum requirements. With Michigan’s adoption of the 2012 International Energy Conservation Code (IECC), an analysis determined statewide annual energy savings of approximately 480,000 MMBtu and $4 million in...
