Study Finds Quick Payback for LEED Investments
Managing principal George Nasis, AIA, and director of environmental research Bryna Dunn, Assoc. AIA, both of Moseley Architects in Richmond, Virginia, studied three of the firm’s LEED-certified institutional buildings and found paybacks for green features of under four years based on energy savings alone. Nasis and Dunn monitored energy use in the buildings and compared it to the energy use of a baseline building meeting minimum ASHRAE 90.1 requirements. Using the firm’s average LEED premium of 1.5% for design and construction costs, they calculated simple payback figures of 1.7 years, 2.7 years, and 3.9 years (see table). According to Dunn, calculating the baseline figures was far from easy, especially for the renovation and expansion of a recreation building at William and Mary College, which had been built to earlier codes with different requirements for ventilation, lighting, and other energy-using features.
