Areas under the roof receive an extra layer of rigid foam insulation prior to drywall
The exterior of THE CONCORD GREEN HOME is almost complete, save the front elevation, which is still sporting its pink rigid foam insulation. As soon as the weather clears, the front facade will finally match the rest of the house.
Meanwhile, once the interior is bone dry (by starting up the new radiant heat and some dehumidifiers), open-cell spray foam will coat the entire assembly. This will be followed by drywall and plaster skimcoat, in order to achieve a well-sealed air & water-tight building envelope.
We had planned on using closed-cell insulation for its somewhat higher R-values, however, open-cell foam, like Icynene, does not require a multi-week curing time as it continues to off-gas chemicals. In this case, indoor air quality trumps slightly better efficiency gains.

Thoreau's Cabin - On Walden Pond
"I went to the woods because I wished to live deliberately. To front only the essential facts of life and see if I could not learn what it had to teach and not, when I came to die, discover that I had not lived." - Henry David Thoreau
Design Excellence = Old + New
THE CONCORD GREEN HEALTHY HOME harnesses the best of old and new building principles. Like our ancestors, we respected the position of the warming sun, cooling breeze and shady trees. Better than the past, we super-insulated to retain comfortable indoor temps and minimize energy use. The home is rooted in classical architecture, but was panelized off-site to cut waste and protect materials from weather, thus reducing chance of rot and mold.
A big thanks to the design team members, who were open to the rather frightening idea of having two sets of architects for THE CONCORD GREEN HEALTHY HOME: ZeroEnergy Design, green architects/mechanical designers, and Connor Homes, creators of reproduction "New Old Homes". This project would not be possible without Aedi Construction, our resourceful healthy home builder.
To Sam, my rock. Thank you for your love, your steadfast support, your ability to make me laugh no matter what, and your patience with my "canary" ways. Without you, none of this work would be possible.
