Re-Assessing Green Building Performance

20 December 2011

This paper, put forward by the US Department of Energy, informs the General Services Administration on how their sustainably designed buildings are performing in comparison to industry baselines of typically designed buildings for energy, water, maintenance and operations, waste, recycling, occupant commute and occupant satisfaction.

It assesses the green building performance of 22 GSA buildings which use less energy and water, cost less to maintain and have occupants that are satisfied when compared to typical buildings.

The study found these buildings' aggregate operations costs are 19% lower than industry average, carbon dioxide equivalent emissions are 34% lower than typical buildings and the US Green Building Council Leadership in Energy and Environmental Design (LEED) Gold rated buildings generally perform better when compared to industry baselines.
