Green Roofs
PhD student Tim Carter established a vegetated roof research site
on the Science Library-Boyd Hall Graduate Studies building on the campus
of the University of Georgia. The roof was installed September 30 -
October 1, 2003 with assistance from the Office of the University Architect
and UGA Physical Plant, as well as faculty, staff and students of the
Institute of Ecology. It was planted in various Sedum species
that are drought-tolerant and can thrive in the harsh conditions of
a rooftop. A lightweight, engineered growing medium enables roofs to
be retrofitted with this vegetative cover. The roof continues to be studied
for its ability to retain stormwater as part of a larger urban watershed
remediation project.
For more information about this project, please contact Tim Carter
