This paper provides the first credible evidence on the economic value of the certification of “green buildings” – value derived from impersonal market transactions rather than engineering estimates. For some 10,000 subject and control buildings, we match publicly available information on the addresses of Energy Star and LEED-rated office buildings to the characteristics of these buildings, their rental rates and selling prices. We find that buildings with a “green rating” command rental rates that are roughly three percent higher per square foot than otherwise identical buildings – controlling for the quality and the specific location of office buildings. Ceteris paribus, premiums in effective rents are even higher – above six percent. Selling prices of green buildings are higher by about 16 percent.

For the Energy-Star-certified buildings in this sample, we subsequently obtained detailed estimates of site and source energy usage from the U.S. Environmental Protection Agency. Our analysis establishes that variations in the premium for green office buildings are systematically related to their energy-saving characteristics. For example, calculations show that a one dollar saving in energy costs from increased thermal efficiency yields roughly 18 dollars in the increased valuation of an Energy-Star certified building. Beyond the direct effects of energy savings, further evidence suggests that the intangible effects of the label itself also play a role in determining the value of green buildings in the marketplace.

This paper provides the first systematic analysis of the choice by organizations to occupy green office space. We develop a framework of ecological responsiveness, and we formulate five propositions to explain why specific firms and industries may be more likely to lease green space. We test these propositions by analyzing the decisions of more than 11,000 tenants to choose office space in green buildings or in otherwise comparable non-green buildings located nearby. We find that corporations in the oil and banking industries, as well as government-related and non-profit organizations, are among the most prominent green tenants. After appropriately controlling for building quality and for location within one quarter mile, our empirical analysis shows that firms in mining and construction and organizations in public administration are relatively more likely to lease green rather than conventional office space. Furthermore, organizations employing higher levels of human capital (as measured by skills and compensation) are more likely to lease green office space.

Research on climate change suggests that small improvements in the "sustainability" of buildings can have large effects on greenhouse gas emissions and on energy efficiency in the economy. This paper analyzes the economics of "green" building. First, we analyze a panel of office buildings "certified" by independent rating agencies, finding that large recent increases in the supply of green buildings and the unprecedented volatility in property markets have not significantly affected the relative returns to green buildings. Second, we analyze a large cross section of office buildings, demonstrating that economic premiums in rent and asset values are substantial. Third, we relate the economic premiums for green buildings to their sustainability, confirming that the attributes rated for both thermal efficiency and sustainability contribute to premiums in rents and asset values. Even among green buildings, increased energy efficiency is fully capitalized into rents and asset values.

Our analysis establishes that variations in the premium for green office buildings are systematically related to their energy-saving characteristics. For example, an increase of ten percent in the site energy utilization efficiency of a green building is associated with a two percent increase in selling price - over and above the 16 percent premium for a labeled building. Further calculations suggest that a one dollar saving in energy costs from increased thermal efficiency yields roughly eighteen dollars in the increased valuation of an Energy-Star certified building.
