This paper examines the effect of energy benchmarking on the marketability of commercial buildings in a selection of U.S. cities (New York City, San Francisco, Chicago, Washington DC). The analysis suggests that it is difficult to determine if the policy impacts on energy efficient buildings are more positive than less energy-efficient buildings since there are other multiple factors influencing real estate performance. Further research is needed to ascertain if disclosed energy performance has an impact on marketability.
