'Greening Work Styles: Analysis of Energy Behavior Programs in the Workplace' is a report written by the American Council for an Energy-Efficient Economy.

The report focuses on energy behavior programs in the workplace, which aim to reduce building energy use through change in employees’ attitudes and behaviors. It examines five energy-saving programs in the United States and Canada including Green the Capitol effort in Washington, D.C., and the tenant management strategy at the Empire State Building.

Energy savings of the studied energy behavior projects are from 4% (savings from a stand-alone behavior program) to nearly 75% (savings from a comprehensive project in which a behavior program is a component).The report suggests that the energy research community and energy efficiency professionals should work together to develop an improved evaluation framework to better document, study, and evaluate energy behavior programs.
