Five Steps to Net Zero
This guide is an introduction to how architects and engineers can help clients upgrade their existing buildings to be ZNE through a Deep Energy Retrofit combined with renewable energy sources. A Deep Energy Retrofit is an existing building retrofit that improves building performance by at least 30%.
