Introduction
Starting April 22, 2025, Michigan will enforce a new Commercial Energy Code, aligning with the 2021 International Energy Conservation Code (IECC) and ASHRAE Standard 90.1-2019. This update signifies a substantial shift in building energy efficiency requirements, impacting new constructions, additions, and significant renovations. For facility managers and building owners, understanding these changes is crucial to ensure compliance, optimize energy performance, and capitalize on potential incentives.
Key Changes in the 2025 Energy Code
1. Adoption of IECC 2021 and ASHRAE 90.1-2019
Michigan’s new code mandates adherence to either the IECC 2021 with state-specific amendments or ASHRAE 90.1-2019 with particular lighting amendments. This dual-path approach offers flexibility while ensuring that buildings meet stringent energy efficiency standards. greatlakeswire.com
2. Functional Performance Testing (FPT)
A significant addition is the requirement for Functional Performance Testing. FPT is a process that verifies the operation of building systems—such as HVAC, lighting, and water heating—to ensure they perform as intended under various conditions. This testing is less intensive than full commissioning but is essential for validating energy efficiency measures. PBA Blog+3ABC Western Michigan+3ABC Western Michigan+3
3. Expanded Commissioning Requirements
Previously, formal commissioning was required for buildings over 50,000 square feet. The new code lowers this threshold to 10,000 square feet, emphasizing the importance of verifying that building systems are designed, installed, and calibrated to operate as intended. PBA Blog
4. Enhanced Lighting Controls
The updated code places a greater emphasis on energy-efficient lighting systems, including the use of 100% LED technology and advanced lighting controls. These measures aim to reduce energy consumption and improve occupant comfort. PBA Blog
