CoStar Study Finds Energy Star, LEED Bldgs. Outperform Peers
Demand in Marketplace for Sustainability Creates Higher Occupancy Rates, Stronger Rents and Sale Prices in 'Green' Buildings
By Andrew C. Burr, March 26, 2008
A new study by CoStar Group has found that sustainable "green" buildings outperform their non-green peer assets in key areas such as occupancy, sale price and rental rates, sometimes by wide margins.
The results indicate a broader demand by property investors and tenants for buildings that have earned either LEED® certification or the Energy Star® label and strengthen the "business case" for green buildings, which proponents have increasingly cast as financially sound investments.
According to the CoStar study, LEED buildings command rent premiums of $11.33 per square foot over their non-LEED peers and have 4.1 percent higher occupancy. Rental rates in Energy Star buildings represent a $2.40 per square foot premium over comparable non-Energy Star buildings and have 3.6 percent higher occupancy. (For Complete Story Click Here)
