Eco-labeling in commercial office markets: Do LEED and Energy Star offices obtain multiple premiums?

This paper investigates the effect of eco-labeling on rental rates, sale prices and occupancy rates. The consensus emerging from previous studies appears to be that investors in and occupiers of eco-labeled buildings obtain a bundle of benefits related to lower operating costs, reputation benefits and productivity higher. In this study, a hedonic model is used to test whether the presence of an eco-label has a significantly positive effect on rental rates, sale prices and occupancy rates of commercial office buildings in the US. The results suggest that office buildings with Energy Star or LEED eco-labels obtain rental premia of approximately 3-5%. Dual certification produces an additive effect with rental premia estimated at 9%. Respective sale price premia for Energy Star and LEED labeled office buildings are 18% and 25%. The sale price premium for dual certification is estimated at 28-29%. An occupancy premium could not be confirmed for LEED labeled office buildings and only a small positive occupancy premium was found for Energy Star. (C) 2011 Elsevier B.V. All rights reserved.
