About Build It Green

Our mission is to create a world of healthy and sustainable homes for all people

Who We Are

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.

How We Work

We are driven by the recognition that housing is foundational to our health and safety—and to our clean energy future.

We are passionate about bringing innovation to market, and inspired to support consumers, professionals, private companies, and public agencies.

What We Focus On

To achieve the greatest impact, we focus on three goals:

  1. 1

    Driving deep reductions in carbon emissions by connecting more homes to clean power and advanced energy technologies

  2. 2

    Creating a real estate market that recognizes the value of these homes

  3. 3

    Ensuring that these benefits are accessible and affordable to all communities, including low-income communities

Our vision is for all people to thrive in homes that enhance our well-being, protect our environment, and ensure a stable and prosperous future for our children

Why Our Work Matters

Climate change threatens our safety and prosperity. We must change the way we design, build, and upgrade our homes to decrease carbon emissions dramatically. In doing so, we'll also create economic opportunity and make homes more affordable and healthy, especially for vulnerable populations.

What We Can Achieve

Every house can become a high-performing home that:



    Produces as much energy as it consumes


    Minimizes waste and utilizes sustainable materials


    Conserves and recycles precious water


    Maintains lower utility bills to make housing more affordable for all


    Maintains safety and indoor air quality to enhance our health and well-being
