The CUNY system accounts for one percent of the total amount of electricity consumed in New York City. Here are some examples of the positive steps we're taking to use less energy:
Occupancy Sensors. Ninety percent of all rooms on Hunter's campuses are equipped with occupancy sensors, which control the overhead lighting. If a sensor does not detect motion inside a room for 15 continuous minutes, the lights in the room automatically shut off.
Power Down: Escalators & Elevators. During times when Hunter's main campus is less heavily occupied, some escalators and elevators are powered down. For example, in the West Building of Hunter's main campus, escalators on the fourth floor and higher are turned off on evenings and weekends.
Power Down: Peak Load Management. Hunter participates in Peak Load Management, a program administered by the New York Power Authority. Extremely hot summer days put extra strain on New York's power grid, and Hunter has agreed to reduce its share of that burden. On a few of the very hottest days, the College powers down some of the elevators and escalators that it would normally keep running, and it reduces its air conditioning capacity.
Pool Renovation. Savings have been integrated into the newly-completed Hunter pool. A high-efficiency dehumidification unit was installed, to reduce energy use. In addition, the pool will be covered when not in use, conferring further benefits: 1) the rate at which pool water evaporates will be slowed, decreasing the frequency with which water and chemicals will need to be added to the pool; 2) decreased evaporation means that the dehumidifier unit will be activated less often and for shorter periods of time, translating into energy savings; and 3) the cover will insulate the pool, keeping its heated water warm longer, so that the water heating unit won't need to operate as often or as long--again, saving energy.
Efficient Ventilation. With support from the Dormitory Authority of the State of New York, Hunter has upgraded to high-efficiency air compressors to supply the main campus with heating, ventilation and air conditioning. The energy used to power these compressors is substantially reduced in comparison to the compressors formerly in place.
Water Filtration. Hunter has invested in Quench systems--water dispensing units which are connected directly to the municipal water supply. They filter and expose tap water to ultraviolet light to ensure its purity. Hunter employees now enjoy an endless supply of pure, clean drinking water, cold or hot. In doing so, they are encouraged to avoid consuming bottled water, in turn reducing the volume of empty plastic bottles that enter the waste stream.
