I think I’ve mentioned before that it has been a once-in-a-lifetime opportunity to work with an amazing artist and sculptor on their net zero, passive house.  We took the day to visit the site in New Jersey and it was thrilling to walk through these spaces that as complicated as they were in 2D, I was able to create the 3D visualization in my head to successfully build a set of construction drawings.  But there is nothing like walking through the actual spaces that now physically exist.
So many great things happening with this project – foam-free and net zero; perlite under slab; pre-manufactured wall trusses as the insulation cavity; low-cost, DIY construction techniques; and creative use of color and material.
I can’t forget to add the experience of exceptional lunches from the garden with every visit!

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.

4. Swap old counter tops with eco-friendly ones
If you plan to install an island or replace the old counter tops, try and go green. Green materials not only reduce the carbon footprint, they also give a distinct look to the kitchen. Recycled paper (refer picture), recycled steel, concrete, engineered stone etc. are interesting and distinct materials you could consider. 

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!

 

Carri and Michael’s home renovation is being featured as a Guest Blog on Green Building Advisor!

Framing is complete, plumbings lines have been run, electrical has been wired, ducts have been installed, and we are moving ahead at full throttle!
In the past few weeks Hayes Construction has put up drywall in all the rooms, installed flooring, given the tile guys the go-ahead, and is in the process of painting the rooms with the colors we chose last week. And the cabinets are in!

The rooms are light-filled and spacious. The family room has a beautiful view of the the water, and a canopy view of the trees, which makes for excellent birdwatching from the windowseat.
The dining room is filled with light and has beautiful patio doors that will open onto back deck. And even the basement has a beautiful concrete floor and plenty of light.

The mason did a superb job on the chimney, capturing Carri’s vision to blend the stone into the brick like a french country villa.

Hayes has been wonderful to work with thus far and communication has been great. Anytime they hit a snag we talk about it at our weekly meetings  to come to a solution, which makes the process much smoother.

That’s all for now folks, until next time!

Upon the arrival of the Roxul mineral wool insulation for sub slab, the contractor relaid the Stego vapor barrier (taped to edges at perimeter).  This delay actually may have been a good thing, as the mineral wool was protected from the elements and heavy foot traffic and slab was able to be immediately poured. 
The framing of the second floor and roof are nearing completion.  We are using 2×6 structural walls with 3/4″ plywood sheathing, all edges and corners taped and sealed.  The headers above each opening are two TJIs with Roxul mineral wool sandwiched between them – we have insulated headers!  The lead carpenter did not find it to be time consuming or of any issue, but rather thought it was pretty cool and a no-brainer.
The fireplace is a Rumford fireplace, the most efficient design in providing warmth to a space.
