Yale School of Forestry Kroon Hall

“Kroon Hall represents the transformation of what once was a brownfield into a net-zero educational masterpiece. From heat pumps in the ground, to the 105.6 kilowatt solar electric system on the graceful roof, the new home of Yale’s School of Forestry & Environmental Studies is one that embodies the possibilities of responsible, energy and earth conscious human structures.”

James Gustave Speth, Dean, School of Forestry & Environmental Studies

The Yale School of Forestry and Environmental Studies (YFES) is one of the pre-eminent centers of applied scholarship in the fields of environmental studies and science in the world. When YFES wanted to retrofit Kroon Hall, the school’s new home in New Haven, CT, the leadership sought design excellence, aesthetic beauty and carbon neutrality. Alteris Renewables collaborated with the architectural firm hired to oversee the project to deliver the best solar electric design and materials for Yale’s exacting standards and rigorous environmental goals.
