Our Initiatives

Professional Education

The professionals that design, build, and operate buildings are important advocates for net zero, and need a reliable source for the latest trends and technologies. We deliver effective educational programs, convening diverse professional stakeholders.

Existing Buildings Support

We believe that all communities deserve healthy, high performing buildings. Through our Neighborhood Power Project and Illinois Green Schools Project programs, we provide the support to show all building types can be net zero.

Green Building Policy

We must remove barriers by providing information about the technical and policy roadblocks to net zero adoption. We amplify building professional voices that impact green building policy and support the passage of major climate laws.

What We Believe

To combat climate change in Illinois, it's time we made net zero buildings feasible, affordable, and so commonplace that every building in Illinois by 2050 is net zero. Mainstreaming the technology and building methods, whether new or existing, will not be easy but no one is better positioned to make it happen than green building professionals.

Our Community

"I chose to be a member and a volunteer for Illinois Green Alliance to grow my network of connections, and by joining I gained more than I could ever imagine. Over the past six years my colleagues have grown to be my friends, and I learn something new about sustainability, life, and myself through everyone and every event I attend."
