Energy Conservation

Rockefeller endeavors to reduce consumption of energy, fuel and water whenever possible.

Lighting on Campus

  • Light fixtures and bulbs have been standardized; fewer types of bulbs are needed, allowing purchasing by bulk and a corresponding reduction in packaging.
  • Reflectors have been added to many lights, so lower wattage bulbs can be used to create the same amount of light.
  • Motion sensors automatically turn off lights when rooms are empty.
  • Use of low-energy compact florescent light bulbs has increased.
  • LEDs (light emitting diodes) are used when possible.

Buildings & Machinery

  • New piping installed in the chiller plant salvages water from condensation equipment and directs it back to boilers and chillers to be recycled.
  • All chillers are tested for leaks at least once a month in order to eliminate refrigerant loss.
  • Thermostats are turned down in office areas, hallways, classrooms and lobbies when the university is closed. In some cases, equipment is turned off altogether.
  • Thermostats are set closer to outdoor temperatures.
  • Every motor and pump (5 horsepower and greater) on campus is on a variable frequency drive so they only run as fast as they need to run at any time.
  • A large percentage of air in administrative buildings is recycled so air conditioners do not need to cool outside air.
  • Flue gas recirculation is used for the power plant boilers.
  • Gas exhaust is burned from the boilers, which reduces nitrous oxide emissions up to 60%.
