30 panels atop New Hall consist of evacuated tubes, which are used to heat domestic water for showers and sinks. It saves approximately 3,810 therms a year, accounting for 30% of the hot water needs for the occupants.
Solar Photovoltaic (PV) Panels
1,632 solar pv panels and an energy storage system have been installed on the roof the Residence Hall and Recreation Center. This system will provide 22% of the building's electricity. View the real-time energy production HERE.
No natural gas lines are connected to Residence Hall/Recreation Center. Instead, geothermal heat pumps use steady underground temperatures to heat and cool the building cleanly and inexpensively. The geothermal field, located directly south of the building, contains 60 vertical underground loops protruding 650 feet into the ground.
In Winter 2014, new LED lights were installed inside Gregory Arena and the pool deck in Merner Field House. Since then, the College has installed LEDs outside Merner Field House, in the Residence Hall/Recreation Center Arena, the 2nd floor of White Activities Center, and many other locations. By changing to LEDs, the College has greatly decrease energy consumption and costs.
To reduce campus impact on the urban heat island effect and improve energy efficiency many buildings on campus were constructed with white or lighter colored rooftops. The Residence Hall/Recreation Center has an Energy-Star rated white roof membrane, which helped achieve points in the LEED certification process.
With the help of two grants from the City of Naperville’s Greener Business Program, the College was able to install occupancy sensors in offices, storage closets, bathrooms, mechanical rooms, and some hallways of buildings considered to be the campus’s largest energy consumers. This project not only decreases electricity use and costs, but aids in modifying behavior in locations where occupancy sensors are not installed.
T-8 Lighting Retrofit
All campus buildings were included in a lighting retrofit project to decrease energy consumption and costs. To date, all T-12 ballasts and bulbs have been replaced with T-8s, which use approximately 40 percent less energy and produce a better quality of lighting.
