More than 30 companies have committed to the principles of the U.S. Green Building Council by becoming platinum members, the association said. 

Platinum is highest of the four levels available to companies and organizations. 

“USGBC’s platinum-level members represent some of the world’s most innovative, forward-thinking corporations and organizations, and we are proud to count on them as partners in the green building movement,” said Rick Fedrizzi, the president, CEO and founder of the USGBC. “USGBC’s global relevance helps members grow their business by joining a diverse community dedicated to advancing the latest in innovative building practices. We bring together local and international, big and small, mission- and market-driven businesses and organizations that make direct impacts within their own spheres of influence and collectively advance the movement for a more sustainable built environment.”

HVAC-related companies among the platinum organizations include United Technologies’ Carrier Corp., Lennox International and Johnson Controls.
