Zero Energy Ready Home Requirements



In looking to build a house that was net zero, one that would support itself in the environment with a net zero footprint, we needed to find a standard. There are a few out there but the one that made the most sense to us was the Department of Energy, Zero Energy Ready Home.

To qualify as a DOE Zero Energy Ready Home, a home shall meet the minimum requirements specified below, be verified and field-tested in accordance with HERS Standards by an approved verifier, and meet all applicable codes. The following criteria are summarized from those that can be found at: http://www.energy.gov/sites/prod/files/2014/04/f15/doe_zero_energy_ready_home_requirements_rev04.pdf

Those Requirements Include:
