The Auburn University Green Infrastructure Team is studying thermal inputs to stormwater systems.  The team includes faculty researchers Amy Wright, Horticulture, Mark Dougherty, Biosystems Engineering, Keith Rahn, Building Science, and Charlene LeBleu, FASLA, Landscape Architecture. Graduate Research Assistants include MLA students Andres Orjuela, Student ASLA; Britton Garrett; Rui Wang, Student ASLA; and Ryan Bowen, MLA & Master of Building Science. The research is conducted in the Green Infrastructure Laboratory at the Mike Hubbard Center for Advanced Science, Innovation and Commerce (CASIC) Building. The laboratory provides a controlled environment, and is designed for both wet and dry research. The center was built with funding provided by a grant from the U.S. Department of Commerce’s National Institute of Standards and Technology, and the Alabama Agricultural Experiment Station. The main purpose of this research is to develop design models for standard stormwater control measures that can be used to meet specific effluent temperature standards and to maintain the required thermal regime in a receiving stream. This project hypothesizes that pervious surfaces, turfgrass and rain gardens can be used to mitigate ground level thermal loads in stormwater runoff.
