Inquiry
Generally, where is the garage plane defined for IEQ credit 10? If the supply ducting is installed above the garage, is that acceptable? The ducts are sealed, and the garage ceiling is painted drywall and sealed using caulked Thermopan and spray foam.
Ruling
Within LEED for Homes, the garage is defined by its fire-rated envelope, so any ducts that are located outside the fire-rated envelope are considered outside of the garage. See EQ 10-09a for details about locating the AHU in a sealed closet that opens into the garage.
