Great Green Home | Birch House by Bundle Design Studio

May 5, 2017

This living laboratory is a home performance triple-play: zero energy, zero water, and zero sewer. Solar panels produce more power than the highly efficient home uses in a year, while rain water provides all of the home’s water supply and waste water is disposed on site.

Architect Dan Welch of Bundle Design Studio and builder Chris Tretwold of Tretwold Construction built the home to the high energy performance standards of the U.S. Department of Energy Zero Energy Ready Home program. All DOE Zero Energy Ready homes must be certified to ENERGY STAR Certified Homes Version 3.0 and the U.S. Environmental Protection Agency’s Indoor airPLUS program. Each home meets the hot water distribution requirements of the EPA’s WaterSense program and the insulation requirements of the 2012 International Energy Conservation Code. In addition, homes are required to have solar electric panels installed or have the conduit and electrical panel space in place for future installation of solar panels
