In NYC, vacancy sensors are helping schools save energy and money. The Department of Education, with funding from the DCAS Energy Management ACE Program, is working to install the sensors in 90 school buildings across the boroughs.
Vacancy sensors detect body heat in order to determine whether anyone is in the classroom and turn lights on or off. This small technology means huge savings, cutting as much as 45% of total lighting energy use. In fact, the sensors are expected to save over 17 million kilowatt hours per year, reducing greenhouse gas emissions by 3,000 metric tons.
This initiative is part of DCAS Energy Management’s larger project of reducing greenhouse gas emissions by retrofitting older city-owned buildings to be more efficient. Currently, there are over 160 energy efficiency projects for city-owned buildings in progress.
