District cooling may be right for you if:

  • Your building is within a few blocks of a plant's piping network
  • You are considering an HVAC retrofit
  • You want to reduce up-front capital equipment costs with new or existing construction
  • You want to reduce ongoing equipment and maintenance costs
  • You want to reduce the requirement and cost of electrical service
  • You want to increase your real estate revenue by repurposing your roof and/or mechanical room space

What Is District Cooling?

District cooling provides customers their HVAC requirements through a network of underground pipes. It serves multiple buildings within a particular service area.

A district cooling plant distributes chilled water (approximately 44 to 45 degrees) to the customer's building through a set of heat exchangers located in the customer's mechanical room. A single plant can meet the cooling needs of several buildings.

Cool water flows between the District Cooling plants and the buildings they serve.
