Build It Green

Build It Green (BIG) is a nonprofit organization comprised of thought leaders and building industry veterans who share a vision for better buildings and a diligence for getting results. Our pioneering work is transforming how homes are built and renovated in California and beyond. We serve as an ally and partner to thousands of building and home professionals—builders, contractors, architects, raters, and realtors. We offer training, support, and programs to help them build and retrofit greener homes and grow their businesses in the process. We build relationships that drive innovation and impact. In collaboration with our professional network and with industry partners and public agencies, we set technical standards and design and deliver market-friendly solutions, from energy efficiency incentives to green home certification.
