Showcasing sustainability

Green roof installation tops off Applied Technology Center

LiveRoof Hybrid Green Roof System. Grand Rapids Community College (GRCC) offers opportunities for more than 32,000 students annually. It holds classes on its downtown campus in Grand Rapids, Mich., as well as other locations.

GRCC regards sustainability as a crucial form of innovation that provides a framework by which the college can improve the well-being of all living things and the health of the planet through education, modeling best practices, networking with other institutions, and discovering and developing new methods. A Sustainability Advisory Council (made up of faculty, staff, administration and students) supports efforts to develop curriculum that challenges students to apply learning and adopt sustainable practices into their daily lives, integrate sustainability through facilities management and operations, and encourage meaningful, long-term community engagement.

One of the most visible manifestations of GRCC’s commitment to sustainability is the Applied Technology Center green roof. GRCC undertook extensive research before specifying a green roof system.

“The green roof is important for its practical benefits—protecting the waterproof membrane to extend its service life, insulating the roof to reduce building energy use, reducing stormwater runoff,” says Jim Van Dokkumburg, director of facilities planning and projects. “More than that, by incorporating access and signage into the project, it becomes a showcase for education on sustainability.”

The green roof has two sections. The high roof area is the main section and has access via a rooftop observation deck. The lower section is a terrace and features green roof plants in large planters. It offers outdoor seating for people to enjoy meals from GRCC’s Secchia Institute for Culinary Education.
