Passive house hits the real estate market in Seattle (photos)
Imagine living in new architect-designed home that uses up to 90 percent less heating energy than an average home.
The Green Lake Passive House, in Seattle is on the market for presale offers. Designed by architectural firm Heliotrope Architects, the home will meet the rigorous Passive House green building standard. That means the house will use 80 percent to 90 percent less heating energy than a conventional home, dramatically reducing its carbon footprint. The award-winning architectural design makes it an exemplar of high design in high performance building.
"Our aim was to combine design excellence with cutting-edge building science to prove that sustainable homes can be beautiful, and that high design homes can be sustainable," said Joe Herrin, principal at Heliotrope Architects. "It's a combination not often seen in our region."
While not yet built, the residence has received a Northwest and Pacific Region Design Award from the American Institute of Architects.
Green building features
- Filtered ventilation and leak-free construction will safeguard indoor air quality.
- A high-performance building envelope will ensure thermal comfort.
- Triple-glazed windows and super-insulated walls will eliminate noise transmission from outside.
- Carefully designed day-lighting will create an open and bright interior, maximizing solar heat gain and daylight penetration throughout.
- Outside, the form of the home creates a bold expression clad in warm, natural cedar.
The home's flexible floor plan is well suited to families and couples. The ground level includes a garage, a guest suite or family room, a laundry room and a storage room. The main level includes living, dining, entry and powder room. The upstairs has three bedrooms and two baths. All are connected by a stair floating under a large skylight, with glass floors allowing ample light infiltration below. The total floor area is just shy of 3,000 square feet.
"Heliotrope has designed the Tesla of houses here," said Sam Hagerman, co-owner of high performance builder Hammer & Hand. "Quiet and beautiful, it's the kind of place you don't want to leave."
Project cost as designed, depending upon final finish selections, will total approximately $1,450,000, excluding transaction cost. The buyer will finance the project and the architect/contractor team will see the project through construction on the buyer's behalf. The seller intends an entirely open book approach, with the buyer involved in remaining design decisions (such as finishes, fixtures and appliances) leading to the final selling price.
