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.
