With closed-cell foam insulation in walls and roof, and another layer of rigid insulation on the exterior, the home achieves an airtight R-value of 33*, far higher than code requires. The areas of green roof add visual interest, add to the insulating value, and help achieve the site’s stormwater retention requirements as do the rainwater catchment tanks that can be used for irrigation. The standing seam metal roofing material was chosen for durability and lifespan as was the rainscreen siding assembly. Triple-glazed windows complete the energy efficient envelope.
The home’s interior is attractive and livable and is extended by the many outdoor living spaces that seamlessly incorporate the two environments.. The design elements feature sustainably-minded and healthy materials throughout the home and landscaping. Most all of the trim lumber is certified by the Forest Stewardship Council (FSC), or is reclaimed like the hardwood flooring milled from salvaged oak posts and beams. Low-VOC paints and varnishes are used throughout the interior to attain a healthy indoor air quality. All countertops and some tile are made from recycled content.
