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.

net zero | passive house, western maryland: coming to a close

We are thrilled at the success and completion of our first Foam-Free, (near) Net Zero, Passive House in Western Maryland.  The home is currently in the final stages of testing and certification and interior finishing. It has been an educational process with material usage, system selection and install, air sealing and insulation, window install and team collaboration.

The views and placement of the house are extraordinary and achieve the homeowner’s goal of a comfortable, accessible, high performance home designed to view the meadow, marsh and forest.

net zero | passive house, maryland: mento + furring

Upon hanging the TJI insulation cavity, the vapor open Weather Resistant Barrier (WRB) was installed and all seams were taped.  Given the pressure of the cellulose that will be blown-in behind this WRB, we decided to use Solitex Mento 1000 and taped with our favorite Tescon Vana tape.

The next layer is the ventilation cavity / rainscreen / furring strips.  We decided on horizontal with vertical furring strips to keep the cellulose bulge in check and maintain an acceptable ventilation cavity as well as provide a more substantial nailing surface for our engineered wood siding.
