On September 20, 2017, Michigan became the latest state to join the march toward more advanced commercial energy codes across the country. The changes in Michigan represent the first code updates in more than six years for the state, but continue along a path that other states have taken over the past several years.
For Michigan commercial builders, there is no longer an option to choose between ASHRAE 90.1-2007 or IEC standards. There is now one single standard for lighting and lighting controls, which largely follows ASHRAE 90.1-2013.
Some of these changes include:
- All commercial buildings (including those under 5,000 square feet) must now comply with automatic lighting shut-off requirements.
- More spaces must now have automatic full-off control by an occupancy sensor after a space is vacated. These spaces include small offices, training rooms, restrooms, storage rooms, and many others.
- A new code stipulates that certain spaces, such as stairwells and storage rooms, must now automatically reduce the lighting level by at least 50% to save energy when the space is going unused.
- Automatic daylight responsive controls for sidelighting and toplighting are required when there is the presence of natural daylight through skylights or windows in a space.
- New requirements require hotel/motel guest rooms to automatically turn off lighting when guests leave the room.
The upside of these changes for building owners is that the new code standard should result in 25% more energy efficiency compared with buildings built under the old Michigan standards.
The challenge, of course, is that architects and specifiers in the state must now rapidly become familiar with the next generation of networked lighting control solutions. Fortunately, our team has been active in Michigan for some time and has already helped position our representatives to lead the charge with the emergence of these new codes. And our commitment to making networked lighting controls simple extends beyond our representatives to our direct work with specifiers, installers, and building users.
