This Built Green Five Star home in Whatcom County was selected as a Department of Energy 2019 Housing Innovation Award Winner!

The house is weighted south, toward the sun. With both asymmetrical roofs; longer to the south for solar build-out and a preponderance of south glazing for wintertime passive harvesting, the windows are appropriately shaded, with regionally appropriate eaves and porches, against summertime overheating.

The gross footprint of the house is rectangular, stretched with the long-axis running east-west to maximize space available for solar harvest on roofs and south wall, with much smaller east and west walls which overheat as they take the full force of the sun in summer. The slab-on-grade floor is finished to be left exposed and imparts a visceral, cooling, underfoot mass.

The slab also houses in-floor hydronic heating and radiates warm comfort during the long winter season, which, like all the seasons, can be felt and seen keenly in this house though the diversity of landscape views.

The home also features an open floor plan, with no wasted hallway space. The living area loft provides a sense of grandeur, but the modest-sized bedrooms and bathrooms require less energy and provide balanced efficiency.

This is a Built Green Emerald Star home in West Seattle. It was the first Emerald Star home for TC Legend and the second of its kind built in Seattle! It is also a Department of Energy 2018 Housing Innovation Award Winner and Built Green’s “Green Hammer” Project of the Year!

This floorplan is flexible into the future, with two extra bedrooms already in the program, fitted with egress windows & minimum floor area to meet code; One will partition behind the utility, the 2nd can partition from the recreation room upstairs. So this 3 bedroom main house can grow to 5 bedrooms in a day!

The energy-shell is a simple rectangle, conforming to and ideal 1:1.6 established ratio for temperate environments. SIPs shell construction is post & beam type of load-bearing construction that means internal walls can be moved easily during the life of the building as they carry no load. The post & beam structure is visible as both architecture and a celebration of the woodcraft of the Pacific Northwest.
