Drexel Building Study

In 2010, Drexel University opted to pursue sustainability certification by two
paths, using both the Green Globes® and LEED® rating systems, for the Papadakis Integrated
Sciences Building, a five story, 130,000 square-foot laboratory and classroom building. The
project was first certified as LEED Gold, then assessed to merit an equivalent award of Three
Green Globes.

To determine costs, Associate Professor Dr. Jeffrey Beard in the Department of Construction
Management worked with researchers using carefully designed surveys. The team kept close
track of the hard, soft, and optional costs associated with both certification approaches, and
documented the results in a formal report. Hard costs comprised registration and administration
fees paid directly to USGBC for LEED and to the Green Building Initiative for Green Globes. Soft
costs included energy modeling, fundamental building commissioning, design and construction
premiums, and the cost of owner involvement to participate in certification. Fees associated with
specialty professional consulting services were included in soft costs. In addition, optional costs
were accounted for, mostly for LEED enhanced commissioning.
