Founder & Emeritus
Charlie Miller PE
Charlie founded Studio Sustena (formerly called Roofscapes, Inc. and then Roofmeadow) in 1997 to introduce green roofs to the U.S. He is widely lauded as “the father of green roofs” in North America and the leading expert in the field. Charlie pioneered countless design/engineering strategies, authored four of the six published ASTM green roof standard methods, and was integral to the design of more than 200 green roofs including the first in the U.S. Many of today’s green roof technologies and standards stem from Charlie’s innovation.
Charlie’s interest in water resource management and environmental engineering began in the 1980’s when he focused his attention on best management practices (BMPs) for biofiltration systems, integrated landscape measures, and constructed wetlands. He holds an M.S. in Civil Engineering and M.S. in Geology and Geophysics from the University of Utah, and a B.S. in Chemistry from the College of William & Mary. Charlie lives in Philadelphia with his wife Lyndall.
