Green builders, remodelers, developers and verifiers have all heard the news: The ICC/ASHRAE 700-2015 National Green Building Standard™ has been approved by the American National Standards Institute.

But maybe you haven’t heard the equally great news: The standard can be downloaded as a PDF from the National Association of Home Builders BuilderBooks site. And it’s absolutely free.

If you aren’t familiar with how it works, the standard is a green building rating system that assigns points for green and sustainable building practices in the areas of water, resource and energy efficiency, indoor environmental quality, lot and site development and home owner education. To be certified, builders, residential developers and remodelers must meet certain thresholds across all categories to meet the Bronze, Silver, Gold, or ultra-green Emerald levels of certification.

What’s new in the 2015 edition? Improvements and more stringent rating levels in the energy efficiency section, changes that reflect new stormwater management practices, an expanded universal design section and more. You can get the details in this Home Innovation Research Labs press release. Home Innovation trains and accredits the verifiers that builders hire to certify their green projects.
