ZERO on the Severn: Construction Starting on No Foam, Net Zero Retrofit in Annapolis

We are excited to begin construction on this Net Zero, Deep Energy Retrofit of a 1900’s bungalow set on an amazingly gorgeous, perfectly oriented site on the Severn River in Annapolis.  We are fortunate to have a client dedicated to efficiency, beauty and quality.  The result will be an extraordinary retrofit of a completely inefficient, moldy, run-down house into a foam-free, healthy, zero-energy home.  We are wrapping the existing exterior framing – wall and roof – in 5″ of mineral wool,  replacing and relocating windows with high-performance, triple-glazed windows and completely air sealing to create a Passive House level shell.  We are employing fixed and operable shading devices to provide necessary shading. Materials and design inside and out are natural, durable and environmentally friendly.  This project is another in collaboration with Michael Hindle of Passive to Positive.
