Michigan is updating its commercial building energy codes to create more efficient, sustainable structures. These changes, based on the 2021 IECC and ASHRAE 90.1–2019, are expected to reduce energy use by 12%.
Explore the key updates below to ensure your building projects meet the new compliance standards.
The updates aren’t just regulatory — they’re a blueprint for building smarter and greener. By improving system performance and energy use tracking, these changes help reduce emissions and long-term operating costs.
It’s time to build for the future.
FPT is now required for all commercial buildings (or significant alterations) 10,000 sq. ft. or larger. It ensures that HVAC, lighting, and other systems are optimized for energy efficiency, occupant comfort, and longevity.
FPT must be performed by a qualified third party not involved in the original system design or installation.
The new code requires:
This promotes Michigan’s shift toward greener transportation and cleaner energy use.
