Energy Projects

Lighting Retrofits

In more than 40 buildings around campus, NYU has installed new, energy-efficient lamps and ballasts. These projects improve light quality while saving more than 1.7 million kWh annually. NYU uses both high-effiency linear lighting as well as compact fluorescent bulbs and LEDs to achieve its lighting goals. Click the map to enlarge.

HVAC Occupancy Controls

NYU has installed almost 4,000 occupancy sensors in student rooms in ten residence halls across campus. These sensors communicate with a smart thermostat to automatically lower room temperatures when rooms are unoccupied. Rather than employ a fixed setback temperature, these smart devices calculate the maximum setback possible that will still maintain the preset length amount of time needed to return the student room to the setpoint temperature after reoccupancy. These devices save over 1.2 million kWh and 2,000 Mlbs of steam each year and also allow for early troubleshooting of defective units.


Buildings are like cars – they need regular tune-ups to function at best performance. NYU has a program to perform recommissioning on its building stock. This involves going into the "guts" of a building and checking operation of all equipment and making repairs/upgrades as necessary for energy efficiency and proper operation. NYU has completed the first project (at Broadway Block) and will undertake the process at other properties.

Domestic hot water heaters

In many buildings, large, inefficient fuel oil boilers run all summer just to provide hot water to a few sinks. NYU has a program to add small, efficient water heaters to buildings to allow the main heating boiler to shut down during the summer. Two buildings have already been retrofit in this way, saving around 3,000 gallons of fuel each summer season, with three more projects in the works.

Reheat Shutdowns

Air conditioning systems in some buildings overcool air in the summer and then actually reheat it again as it is delivered to occupied spaces. NYU is working to ameliorate this consumptive process by shutting down these “reheats” where it is possible to do so and by re-adjusting the air conditioning settings, thereby saving energy and money on both the heating and cooling process.
