Building Doctors has been remodeling a home to make it a Net Zero home. This 1200 square foot home built in 1925 needed a lot of help when we started. We have showcased many of the energy efficiency improvements that we put in our customer's homes. Improvements to the building shell with a 65 percent reduction is the overall air leakage of the home with our air sealing, dense packing the walls to R-15, floor insulation to R-19 and attic insulation to an R-50 depth.
An all-electric heat pump to heat and cool the home and an HRV for continuous fresh filtered air since it is close to a busy street.
We installed three separate on-demand tankless water heaters at each of the sink locations. There are two bathrooms and one kitchen.
We have gone so far as to remove the gas meter from this location on July 25, 2017.
