Deep Energy RetrofitPlan the work

• Focus on the whole building from the basement slab to the roof peak.

• Integrate the air, water, vapor and thermal control layers so they are continuous and aligned with each other.

• Pay close attention to transitions.

Deep Energy RetrofitBenefits

• Occupants can stay in home during work• Improved Comfort• Improved indoor air quality• Increased building durability• Reduced energy consumption• Increased value of home• First step to net zero energy home
