 A3 Architects Inc. submitted an entry to a local ideas competition for affordable housing on a site in Wellfleet. This affordable accessible detached structure has a simple gull wing roof designed to collect both solar energy and water, while shielding the south elevation from the strong summer sun. The 36'x 24 building will work with a typical Wellfleet lot, or as a stand-alone design that could be clustered in groups on a site. The design meets the Passive House standard and as such uses 90% less energy than a similar design to code. On Cape there is a significant amount of discussion around affordable housing and rents, but we believe affordable energy costs are imperative as well. While this structure realistically represents an approximately 10% -15% upfront higher costs for insulation, framing and renewables, the initial mechanical costs are significantly reduced. Furthermore, the energy savings to residents over the life of the structure easily justifies the initial expenditure this within the first 2-3 years.

Energy:  Estimated annual energy used (kWh): * Heating & Cooling: +/- 1400 kWh Cooling: +/- 400 kWh DHW: +/- 800 kWh Lighting/appliances: +/- 2000 kWh Total: +/- 4700 kWh Estimated energy produced by PV panels: ** (15) 327 watt panels � total array 4.905 kWh Estimated annual production: +/- 5500 kWh
