Housing & Dining Services project saves energy and money

May 9, 2011

Replacing 488 old refrigerators on campus will result in savings of nearly $22,000 in energy costs and 305,000 kWh of energy usage per year. In addition to energy savings, the project is reducing greenhouse gas emissions at a rate equal to removing at least 41 passenger vehicles off the road for a year.

Lower cost, cleaner environment

In an effort to reduce energy use, greenhouse gas emissions, and utility costs, Housing & Dining Services replaced and recycled 488 old refrigerators in two university apartment communities.

Grant funds from the city of Fort Collins and the Governor’s Energy Office assisted with the purchasing and recycling of the refrigerators.

  •    University Village received 430 new refrigerators, and I-House received 58.
  •    44 tons of metals and plastics were recycled and diverted from the waste stream.
  •    1,200 pounds of refrigerant was safely recovered from the old refrigerators.

Energy savings

The nearly 20-year-old refrigerators were using almost three times the energy of a modern Energy Star-rated refrigerator. Additionally, these old appliances used R-12 refrigerant, which has a high ozone depletion potential (ODP).

  • Each refrigerator replacement will initially save Housing & Dining Services about $45 in energy costs and 625 kWh of energy per year.
  • The 488 new units will result in savings of nearly $22,000 in energy costs and 305,000 kWh of energy usage per year. Savings in energy costs will continue to increase as energy rates continue to rise.
  • In addition to energy savings, this project is reducing greenhouse gas emissions by more than 210 metric tons of CO2 equivalent per year according to the EPA Greenhouse Gas Equivalencies Calculator. This is equal to taking at least 41 passenger vehicles off the road for a year.
