Healthy, Sustainable and Innovative
Here is a design forward architectural home with dynamic spaces that both soothe and invigorate. Its clean modern design is set off by highly effective daylighting techniques that make for a bright but no glare light filled home during even the bleakest of Willamette Valley overcast days. Strategic placement of large areas of glass keeps you emotionally connected to the outside, expanding your sense of space and indoor/outdoor living while maintaining your privacy in an urban environment. Near the burgeoning cutural/commercial development along NE 42nd Ave, the home is located in a neighborhood that has been cited as among the greenest and friendliest in Portland (Sunset Magazine June 2009 and Portland Monthly Spaces Feb/March of the same year).
The focus in the project development was to provide a rich architectural space with a healthy living environment, a very high level of energy efficiency and comfort, to be built using forward looking sustainable practices and materials.
Spending time in the home you sense the quiet calm that the SIPS system (see next paragraph) provides through its efficient air-tight envelope. This envelope also allows for the heat recovery and ventilation system to continuously remove stale air and deliver fresh air to the entire house. The recovery system transfers up to 90% of the captured heat back into the fresh air being brought into the house, thus saving on heating costs. Low/zero VOC and formaldehyde paints and materials were used throughout. A radon barrier and vent system was installed during construction.
Designed by architect Darin Dougherty (Seed Architecure) the house was the first in Portland to be built with floors, walls and roofs of structural insulated panels (SIPS). These panels provide an impressive efficiency of structure as they serve as the framing, sheathing and insulation with little or no additional structural support needed. The system greatly reduces thermal bridging and air infiltration and the insulation value is impressive: R-30 for the walls and R-60 for the ceilings.
Energy efficiency and sustainability guided every decision regarding materials and systems. The exterior uses no paint. Siding is recycled COR-TEN steel and FSC certified wood that was reclaimed from a barn in Happy Valley. Cabinetry throughout the house is framed with bamboo and topped with Fuez counter tops made of curbside recycled glass, cement and fly-ash. The flooring on the main level is cork and on the upper level bamboo. Toilets are low-flow dual flush. All appliances are Energy Star or better. main heat is via 2 Fujitsu “mini-split” heat pumps. A centralized plumbing plan delivers hot water to every tap in seconds.
