This
home is being considered for the LEED Homes
Pilot program. It consists of approximately
4500 square feet of usable space, including
a finished walk up 3rd floor and finished
basement.
Key
features include an air tight and extremely
well insulated envelope, high efficiency
heating system, dual energy recovery ventilation
systems, radiant heating, and a solar domestic
hot water heating system.
Foundation
walls are by Superior walls made off site
and erected on site. The walls consist of
5000 psi high strength concrete with a 1"
thick R5 rigid foam insulation continuous
throughout the walls.
Exterior
walls are framed using Structural Insulated
panels (OSB/foam/OSB), 6.5" thick with
an R22.5 rating continous as there are no
studs. The foam used in the SIP panel
is similar to the foam used on coffee cups,
expanded polystyrene R4/inch. The roof is
stick framed and spray foamed with Icynene
spray foam insulation to complete the envelope.
