18 Απρ 2024 · The insulation requirements within the Michigan Building Code are crafted to maximize energy efficiency, which helps reduce heating and cooling costs and contributes to environmental protection. Michigan has three different climate zones (climate zones 5, 6, and 7).
Michigan has adopted the 2015 International Energy Conservation Code (2015 IECC) as the baseline energy code for residential buildings in the state. You can use the checklist below to verify key residential code requirements that are easy to identify in your home.
The residential provisions of the Michigan Energy Code (MEC) regulate the minimum energy conservation requirements for detached one- and two-family dwellings, atached single-family dwellings, and Group R-2, R-3, or R-4 buildings that are three (3) stories or less in height.
Step-by-Step Instructions. Using the climate zone map to the right, match the jurisdiction to the appropriate IECC climate zone. Use the simplified table of IECC building envelope requirements (below) to determine the basic thermal envelope requirements associated with the jurisdiction.
List the predominant R-values of insulation installed in or on ceiling/roof, walls, foundation (slab, basement wall, crawlspace wall and/or floor) and ducts outside conditioned spaces and U-factors for fenestration. If there is more than 1 value for each component, then the certificate shall list the value covering the largest area.
