Michigan Energy Code Update

Michigan’s Energy Code has an important new update!

Effective February 8th 2016, all new homes and some residential additions or renovations must comply with the updated code standards. The new code has significant changes from the last one so it is important to give these updates a read. Critical changes include:

  • Window U-Factors must be .32 or lower (improved temperture insulation)
  • Crawlspace insulation is R-15 continuous or R-19 cavity (R-value is insulation thikness)
  • Blower door testing is required and the maximum allowable leakage is 4 ACH50 (average unverified home is 10 ACH50)
  • Automatic whole house mechanical ventilation is required
  • Lights and or fixtures must be 75% CFL or LED (much more efficient than traditional bulbs)
  • Band joist insulation needs to be covered with an air-barrier (sheathing or spray-foam)
  • Sealed ductwork is required, and if ANY portion of the ductwork is outside the thermal envelope, it must be tested for airtightness
  • Building cavities may NOT BE USED AS DUCTS, including returns. Fully ducted systems only
