Located in the rural setting of Honeoye Falls, NY, the Rochester Passive House is a clear example of how comfort is achieved though energy efficiency. The 270 m2 home’s traditional farmhouse aesthetic cloaks a 16-inch double-wall assembly that is insulated with dense-packed cellulose, achieving an R-55. The interior load-bearing 2x4 wall acts as a service cavity. The carefully sealed ZIP system on the exterior side of the interior wall is the air barrier layer. A 1.5-inch rain screen gap and a weather resistant barrier layer on the exterior side of the double-wall assembly guard against moisture intrusion. The southern glazing with optimized overhangs ensures maximum solar gain in the winter months and full shade in the summer months.
