Case Study Written by Camron Momyer at Evergreen Certified.

Dwell Development ups its ante once again with its first net zero electricity home. With over eight kW of locally manufactured Itek solar panels, this home is expected to generate more energy than it consumes-putting electricity back onto the grid! Thanks to its professional grade gas fired range and high efficiency gas tankless hot water; this home is lovingly referred to as the "Almost Net Zero Reclaimed Modern." Along with being Dwell's first truly Net Zero Energy home, this address also boasts more reclaimed, recycled, and salvaged materials than any other previous Dwell construction. It sets a new and higher bar for the company's future developments. Here are just a few of the home's many green and cool features:

  • Living roof installed over garage
  • Electric car charging system installed in garage
  • Corrugated metal and wood salvaged from barn in Oregon used for soffits , siding, fencing and interior details
  • Wide plank fir floors salvaged from fallen trees and utility poles
  • Countertops contain 80% recycled content
  • Porcelain tile contains 40-50% recycled content
  • Reclaimed Fir Island counter top and dining room shelf custom designed and built by Dwell
  • Broken concrete from former sidewalk re-purposed to form new walk way to house
  • Cellulose BIBS insulation on all exterior walls with 2x8 advanced framing
  • Envirodry Fluid Applied Air Barrier
  • Atrium triple paned windows
  • Honeywell HRV
  • WaterSense bath fixtures and Niagara Stealth toilets (.8 gallons per flush)
  • Hydronic, in floor heat supplied by 95% efficient on demand system
  • Structured plumbing system with recirculation pump and timer
