Green Canopy Homes: Madison Valley 5-Star

Posted on Feb 28, 2020 in:
  • Case Studies

Two new 5-star single-family homes built by Green Canopy Homes sit on the corner of a block in Madison Valley. While these units are mirror images of each other, one of the units comes equipped with a 12 KW solar panel array while the other is ready for future solar. As part of Green Canopy’s push for Net Zero, they highly encourage homeowners to install panels to help offset the energy the houses consume, despite that energy being low.

With R-23 blown-in fiberglass insulation in the exterior walls, R-62 ceiling insulation, and a U-0.26 window average, these units are well insulated, which aids in reducing the need for space heating and cooling. Even so, the houses are fully equipped with a ducted and ductless mini-split system that will provide comfort to the homeowners in both the summer and winter months. Other features include Panasonic spot ERVs for ventilation, a hybrid heat pump water heater, EnergyStar appliances, and LED lighting that help make these super high performing homes.

On the outside is a combination of siding material that creates a beautiful aesthetic. Beneath the siding, Henry’s Blue Skin and a rainscreen system help keep moisture out of the home. Interior material selections, in tandem with airtightness and moisture management, make this a low-VOC and healthy home.
