Davis Langdon; 2007

A systematic study that addresses questions on the benefits of investments in energy savings and environmental design.  The study results demonstrate that green buildings have higher occupancy rates and lower operating expenses than non-green buildings; green buildings observed higher rental rates by almost $2 dollar per square foot per year net in the second quarter of 2007 and $2.65 higher in the third quarter of 2007;  and green buildings command sales prices of 30 percent more on average.
