As both the prospective owners and the builder of this exceptionally energy-efficent new house and the proprietors of a well-known local construction firm, the clients wanted to use this project as a showcase for potential construction clients, to demonstrate their expertise and ability to accomplish complex projects, as well as raise the sustainability bar in the Corvallis area.
The Contemporary Craftsman-style Passive House that they created has a carbon footprint that is 5 times smaller than that of a typical new Oregon house of a similar size. This footprint is even smaller thanks to a photovoltaic (PV) rooftop system that generates electricity in excess of the home’s annual power needs.
12″ thick walls, enhanced with a 2” layer of carbon-neutral cork insulation, exceptionally efficient triple-glazed windows and doors, PV system, super-efficient heat pump water heater, Energy Star appliances, LED lighting, highest-efficiency heat recovery ventilation (HRV) system, and loads of natural daylighting keep the home’s annual energy consumption so low -in fact- that the owners end up selling excess power back to their local utility.
The house was built with the intent that it would be the owners’ forever home. A lot of thought went into the design to maximize the use of the space, resulting -for example- in a cosy little reading nook ticked under the stairs, and a lofty little ‘skyperch’ office space peaking out above the roof top at the very top end of the stairs.
On the energy side, the Net-Positive house is constructed to last well beyond the owners’ lifetimes, with extremely durable finishes.
