The U.S. Green Building Council – Illinois Chapter is a nonprofit membership driven organization that advances buildings and communities that are sustainable, prosperous and healthy. We achieve this through education, advocacy, and collaboration.

The U.S. Green Building Council – Illinois Chapter is the local affiliate of the U.S. Green Building Council (USGBC), a national non-profit composed of leaders from every sector of the building industry working to promote buildings that are environmentally responsible, profitable and healthy places to live and work. USGBC’s Leadership in Energy and Environmental Design (LEED) Green Building Rating System™ is the nationally accepted benchmark for the design, construction, and operation of high performance green buildings. LEED® provides a roadmap for measuring and documenting success for every building type and phase of a building lifecycle.
The USGBC-Illinois Chapter furthers the work of USGBC through a variety of programs, events, educational and research initiatives, advocacy campaigns, and resources for the local green building community. Annually, the Chapter offers over 100 events and programs for its members and the general public.
