Deep Retrofits. Making existing homes net-zero.
About 1/3 of greenhouse gases come from the buildings we use right now. 70 per cent will still be standing in 2050.
We can’t address climate change just by building new net-zero homes. We need solutions that make the homes we live in right now net-zero to preserve a livable climate. Deep Retrofits are the solution.
