I have a new construction project in climate zone 9 that has 40% glazing. The EDRe is way above the standard and I’ve tried everything to get it to pass but to no avail. Rigid insulation, spray foam, solar hot water, etc. Does anyone have any recommendations? I’ve been having issues with CZ 9 projects under this new code.
Side question: If an attached ADU is being built to the newly constructed home, is the ADU considered new or an addition?
