The 7 Rust Project is likely the most sustainable residential rehab ever done in Western Massachusetts. We converted an 800.s.f. single story, 1948 oil burning house with virtually no insulation, into a state of the art, sustainable home:
• 1600 s.f.
• Two story, four bedroom
• 6.8kw solar
• Close-to-Net-Zero
• Dense-pack cellulose interior insulation
• Gutex wood-fiber exterior insulation
• Attic is R80 loose pack cellulose
• HVAC via high efficiency minisplit heat pumps
Many of the products used in construction were surplus, reclaimed or recycled. (The floors, for example, are 150-year -old douglas fir reclaimed from a demolished motel.) New products were responsibly sourced from local resources whenever possible.
This was our third major construction undertaking.
