Design for a new net-zero-energy house including an airtight and superinsulated enclosure, heat recovery ventilation, and photovoltaic array. Exposed beams in double height living room ceiling. Detached Accessory Dwelling Unit (DADU) wrapped in weathering steel with spiral stair inside. Completed in summer 2018.
This water front home with lake views and covered decks off every major room is precertified as a Passive House. The project team applied best practices for energy efficiency, including superinsulation, extreme air tightness, triple glazed windows, radiant floor heating, heat pump mechanical systems, and a Heat Recovery Ventilator. Under construction, expected to be complete in autumn 2018.
A 1902 house with a clumsy 1960s addition was in derelict condition when the builder bought it from the deceased owner's estate. The corner lot, located in Seattle's Fremont neighborhood, was large and well suited to a grander house.
The existing partial basement was enlarged by excavation and finished out with a play room, workshop, wine cellar, and storage area. The first floor was a keeper, with 11 foot tall ceilings and large windows. Its floor plan was adjusted to provide a spacious new kitchen and family room to go with the existing formal dining room and living room. The entirely new second floor has a master suite, two children's bedrooms and bath, and a laundry closet.
The complete remodel inside and out was undertaken with a focus on green building practices. Demolition waste was recycled or reused on site, air leaks were sealed and the house was fully insulated, all windows are new double glazed, and interior paints, adhesives, and sealants are low toxic. The new heat system is radiant floors at all three levels. Certified Built Green 5 Star, the fourth ever 5 Star remodel/addition.
Initial grocery store tenant improvement in new building, 24234 ft2, in Redmond WA. The electric lighting scheme provides full spectrum, specialty illumination at 1.11 watts per square foot. 28 new skylights flood the sales area with daylight. Waste heat from the refrigeration compressors preheats the hot water used for cooking and washing, and also provides the heat that keeps the building interior warm.
The materials in the store have 40% recycled content, and 30% of them come from within 500 miles of the store. Over 80% of the construction waste was recycled by the builders. Cabinets and incidental lumber were made from FSC certified sustainably harvested wood. Use of only low toxic and low VOC interior paints, adhesives, and sealants, as well as highly filtered ventilation air provide superior indoor air quality for staff and customers.
Certified LEED-CI Gold, the first Gold grocery in the world.
The owner of this house in Shoreline, WA, nearing retirement, wanted a home that she could grow old in. A straight-run stair was designed to accommodate a future chair lift for accessibility to the upper floor as the owner ages, and bathrooms are provided with blocking for future grab bars. The living/dining room, office and master bedroom were all oriented toward the back yard to the east. A crafts room on the south end of the second floor takes advantage of windows on three sides.
The existing foundation and garage were retained for this project and the new house was built above and around them. The ReStore was brought in for a full deconstruction so the home achieved a 76% job site recycling rate. Energy efficiency was achieved by super insulating walls and roof, new radiant floor heating, and a heat recovery ventilator. Certified Built Green 5-star, the third ever 5 Star remodel/addition.
