[tab title=”Overview”]
The Yale School of Forestry and Environmental Studies (YFES) is a world leader in the fields of environmental studies and science. The School’s home, Kroon Hall, was fit with a 105.6 kW solar panel installation that produces clean solar electricity in order to help further the School’s environmental goals. RGS Energy collaborated with the architectural firm hired to oversee the project, and delivered a sleek, powerful system up to Yale’s rigorous standards. The system provides about 25% of Kroon Hall’s electricity and helped it achieve LEED Platinum certification from the U.S. Green Building Council.
