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.

Our Net Zero, Passive House, Foam-Free home in New Jersey is taking shape!  The 2×6 framing has been completed and the plywood air barrier installed and taped.  Taping and air sealing the various overhangs and angles has been a challenge, but thanks to the diligence of the owner and Michael Hindle of Passive to Positive, the initial blower door test is set up to be a success!

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, certification and interior finishing. Most of the progress can be followed on their website, it’s nicely detailed and as such might offer good inspiration to those DIY types. 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.

We are helping to realize a sculptor’s design of the Honeycomb House.  The project is designed to meet Passive House Standards, be Net Zero Ready and will be completely FOAM-FREE. It is a pleasure and a challenge to be part of this creative venture with Michael Hindle of Passive to Positive and Daniel Gantebein, sculptor!
We are thrilled that this project is now under construction.  The owner is serving as general contractor and has overseen the successful initial pour of the basement wall!

As well as the install of our foam-free foundation using perlite under the slab.

The StegoWrap vapor barrier was used and the slab was poured.

Given that this was our foundation plan, I’d say so far, so good!

So thrilled that our team received the award for “Most Resilient Concept” at the bMORE Resilient Competition Reception last night!
Team: Carri Beer, Lili Mundroff, Michael Hindle, Jack Sullivan, Peter I. May Ph.D., Adam Ganser, and Katelin Posthuma.

We now have our LP SmartSide up and looking more like a house, though we are hiding all of our fantastic details.  We have some warm and natural exterior colors waiting to be applied.

The garage and shop have also been built and will be a nice bonus space to this Western Maryland cold, snowy climate.

I took the time to learn about porch types – my favorite is the cedar porch.  The crew at Gosnell worked patiently with me to build what I had envisioned. It is thrilling to see in person and I’m looking forward to the final product with painted siding and stone porch.  The approach to the house is successfully comfortable and happy.

The large bird viewing windows have been covered with plywood for months as we await the delivery and install of our doors and windows.  The client chose INTUS uPVC windows for their performance, cost and manufacturer provided sill extensions.  The fact that the client could visit a local showroom and see these windows in person was also critical to their decision making.
Our window detail went through many rounds of design and mark-up between myself, Michael Hindle, CPHC and the team at Gosnell Builders.  The result is an air + water tight detail with little to no thermal bridging and over-insulating of the frame.  We also maintained our FOAM-FREE insulating details!

Making the 2D line drawings translate into construction reality was not a problem with our eager construction crew.  Though labor intensive, the resulting air tightness and performance will be outstanding.

Not to mention the amazing views for bird watching!
