General Energy Use, Strategies and Systems

Energy Strategies:

Reducing energy loads was the first aim of this project. Structural Insulated Panels with an R-value of 52 compose the roof and the walls have a combined R-value of 32. Slabs near the windows provide thermal mass to capture solar gain and air tightness was a priority during construction. The exterior wall of the operable fireplace is completely encased in brick to prevent thermal bridging.
