OUCooling District Energy Services - A Hot New Way to Keep Cool
Thanks to OUCooling, building owners are enjoying lower A/C-related electric charges and reducing their capital and operational costs, too. This innovative, reliable service enables commercial property owners to outsource the production of chilled water for their air-conditioning needs. Chilled water is energy efficient, with an estimated energy savings of 25 percent over traditional air conditioning.

"OUC has a long tradition of being reliable as well as innovative, and OUCooling is the latest example of that mindset," said former OUC CEO and General Manager Clint Bullock. "Our work with chilled water shows that OUC is committed to our customers by staying on the forefront of new technology and business opportunities".

In downtown Orlando, OUCooling serves more than 30 customers including the Amway Center, the Westin Grand Bohemian Hotel, Lincoln Tower, and First Presbyterian Church. Outside of downtown, OUCooling serves the Sheraton Vistana Villages timeshare development, the Mall at Millenia, and the Orange County Convention Center.

In Parramore, Hughes Supply Inc. already cools its complex with OUCooling's chilled water ducts. The Florida A&M Law School also uses chilled water and expects to realize valuable savings from its partnership with OUC.

Building owners using OUCooling can benefit from smaller mechanical rooms, no insurance requirements, federal income tax savings, and improved property resale value.

Established in 1997, OUCooling's first project was building a chilled water plant for Lockheed Martin in south Orange County. The following year, OUC constructed a "district cooling" plant in downtown Orlando to serve the growing and diverse commercial market there.

OUC expects to build other chiller plants serving commercial campuses, such as timeshare developments, hotels, and retail shopping centers. With an eye toward the future, OUC already is considering additional chiller plants in the International Drive area near the tourist attractions.

How OUCooling Works
All buildings are air-conditioned by chilled water coils. Warm air is blown over these coils, cooling the air as it passes through. With OUCooling, all the equipment used to cool the water (cooling tower, pump and chiller equipment) is housed in one central facility.

Currently, OUC operates two chilled water plants that serve Parramore and downtown Orlando partners. Underground "loops" run from each facility to buildings partnered with OUCooling.

In Parramore and downtown Orlando alone, about 10 miles of underground pipes have the capacity to deliver 15,000 tons of chilled water to businesses. That's enough chilled water to cool about 6,000 residential homes. Additionally, the OUCooling tank at the Orange County Convention Center is a 17.6 million-gallon chilled water storage tank - the largest in the world.

At the facility, water is cooled to 37 degrees and piped to participating buildings to cool them. The water is then recycled to its central facility to be cooled again before repeating the cycle.

For Residential Customers
About 2300 residential customers are served by chilled water in Downtown Orlando. OUCooling replaces the traditional outside air conditioning unit. However, each residential customer still has an air handler on the inside of their unit. This is not an OUC piece of equipment, it is owned by the building. Next to the air handler, likely inside the same closet, there is an OUC meter that measures the amount of chilled water used to cool the home. If the resident turns off their thermostat and notices the meter continuing to move, then there is possibly a broken valve inside the pipe which is supposed to close when the air conditioner is not in use. Contact OUC and we will work closely with building management to ensure the problem is repaired.
