DEM uses the City's facilities as a testing ground for new and innovative technologies that promise to reduce greenhouse gas (GHG) emissions. Current pilot projects include:
- Dimmable ceiling-fixture ballasts at 1 Centre Street
- A Demand Ventilaton System, which will adjust ventilation air flow based on occupancy, at the Manhattan Criminal Court
- Coordinating with Department of Environmental Protection, Department of Parks & Recreation, and the New York Power Authority to assess the feasibility of a biomass plant fueled by woodchips.
