The owner of an existing Acorn house located in the woods in Amagansett, New York came to us with the request to design in its place a modern single-family residence with as much attention to energy use and sustainability as possible. With budget in mind we embarked on an exploration of to achieve this using conventional building methods, which quickly led to a dead end. Enter ASUL, a company from Arizona that specializes in a system based design methodology and a kit of parts site-built assembly process. Through this collaboration we were able to achieve the design at a much lower cost to the client. While the owner initially had hopes of employing roof mounted solar panels to generate electricity, and a geothermal system for cooling and heating, it soon became clear that neither the large forest canopy, nor the heavy clay content of the soil were going to make either feasible. Maximizing the solar orientation, we turned to integrating passive solar design principles into the structure. A large overhang and the deciduous trees allow for natural shading in the summer. In the winter, the low sun penetrates glass with a very high solar heat gain coefficient, and heats the floor, which in and of itself acts as a thermal mass. The portion of the roof that does receive adequate sunlight receives solar hot water heaters. These panels tie into an advanced mechanical system to provide radiant heating throughout the house. The north wall is heavily insulated, with strategic openings used for cross ventilation. The combination of a high level of attention to insulation and air quality throughout give the house an Energy Star rating.
