Study energy retrofits to vents at the top of stairwells and elevator shaft in existing high-rise buildings.

Steven Winter Associates will develop and test methods for estimating the savings potential for partially or fully sealing these opening using tools common to energy auditors. The costs and benefits of best practice approaches for reducing energy losses through elevator and stairwell vents will be determined. A technical report will also be prepared for building owners, coop board of directors and energy auditors.
