Green still adds value


Even in a volatile market, green office buildings post significantly better returns than their less-environmentally friendly competitors. Those are among the findings from a recent study by Nils Kok and Pier Eichholtz of Maastricht University in the Netherlands and John M. Quigley of the University of California at Berkeley. Using data from more than 25,000 commercial buildings on the listing site of the CoStar Group, the authors determined that buildings holding either the Energy Star rating from the U.S. Environmental Protection Agency or the LEED certification from the U.S. Green Building Council had rents that averaged 3 percent higher than comparable office buildings in the same market. In 2007, effective rents—the rent multiplied by the occupancy rate—for green buildings averaged 7.5 percent higher; by 2009, the rent premium had dropped to 5.1 percent. The authors note that some of this variation could occur because green buildings are often newer and larger than competitors.

The study, “The Economics of Green Building,” also determined that between 2004 and 2009, green buildings listed on CoStar sold for about 13 percent more than comparable properties. “This strongly suggests that property investors value the lower risk premium—perhaps the insurance against future increases in energy prices—inherent in certified commercial office buildings,” conclude the authors.
