A plan to purchase items that do not contain or use chlorofluorocarbons and is therefore "ozone safe". As part of this plan, switched a chiller over to a non-ozone depleting refrigerant and 12,000 lb of CFCs (R-12) was retired.
Focuses on optimum utilization of equipment that uses chilled water, and controlling chill water supply and return temperatures.
The University central utilities plant was upgraded during summer 2006 to introduce a cleaner, more efficient way to meet energy needs. The cogeneration process allows for the simultaneous production of heat and electricity meeting more than half of the annual electric requirement of the River Campus and Medical Center. The change results in a reduction in carbon dioxide emissions of more than 30,000 tons annually. In addition to the environmental gains, cogeneration is cost effective. It saves the University about $3 million a year in electricity costs.
Using clean renewable energy sourced from the sun, wind, water and waste to power central utilities.
Provides an energy savings by converting from steam heat to hot water heat, which utilizes the hot water by-product of Co-Gen.
Prior to 1998, heating and cooling the University required the emission of up to 335 tons per year of NOx (Oxides of Nitrogen). Then the University switched from coal to natural gas and the Central Plant team installed burners that would meet anticipated future emissions standards. This lowered the University's annual NOx emissions to 74 tons per year.
The Central Utilities plant uses a low sulfur fuel oil (0.05%) which helps alleviate unpleasant odors as well as significantly cut sulfur dioxide emissions. Since converting to natural gas and low sulfur oil, annual emissions of sulfur dioxide has dropped from 1,600 tons per year to 1.25 tons per year for 2005.
Records the energy usage for electricity, chilled water, city water, steam and hot water as it is being used.
