Revell Retrofit
a Two-Family Deep Energy Retrofit with National Grid
General Energy Use, Strategies and Systems
Energy Use:
all-electric
superinsulation
high-efficiency heat pumps
ERV to reduce heat loss
EV charges simply from an outdoor outlet
Energy Strategies:
We decided to go all-electric as that allows us to most easily source our fuel sustainably. By eliminating fossil fuels from all of our heating, cooking, and even transportation, we are able to immediately purchase green energy even though we can't put PV right on our roof.
