A reporter from North Carolina called last week to ask me about net-zero energy homes. He hadn’t yet heard that there are net-zero energy certifications, so I filled him in. There are several out and in the works, and sure to be more soon:
- Net Zero Energy Home Coalition (US + Canada) is working on consensus-based definitions for net-zero and net-zero-ready homes to be used throughout the home building industry; these definitions will likely form the basis of emerging certification programs.
- Living Building Challenge‘s Net Zero Building program is operational and ILBI just announced the first two certifications: https://ilbi.org/news-documents/two
- Earth Advantage Zero is in its pilot phase, with a number of homes participating near Bend, OR, with more joining soon in Portland and elsewhere,
- The California Energy Commission, absent any specific program, recently pronounced a Silicon Valley home to be the first “certified” net-zero home in California: http://oneskyhomes.com/news/cottle-project-receives-california-energy-commission-recognition … though it’s not the first home in CA to achieve net-zero energy (or better) without benefit of certification.
- The US DOE is rebranding its Builders Challenge Program as “DOE Challenge Home.” Not explicitly billed by DOE as a net-zero energy program, that’s nevertheless the basic idea.
