Our goal was to design and build a sustainable home within the economic constraints of the time. The William Street house exemplifies our belief that thoughtful architecture—built with one’s own hands—can have a profound impact on people and neighborhoods, and that low-cost, energy-efficient homes can be built within the context of existing, urban neighborhoods.
Insulated concrete forms (ICFs) were the primary structural system used for the foundation and wall assemblies, simultaneously giving the walls high thermal insulation and thermal mass. Window size and orientation was dictated by passive solar and day lighting opportunities. Operable windows were strategically located to maximize cross-ventilation. Additionally, north-facing, clerestory windows in the bedrooms make artificial light unnecessary during daylight hours. Radiant heating combined with a high-efficiency boiler provide an efficient heating system, while cooling is achieved with operable windows and zone-cooling systems.
