District Cooling

District Cooling

Steam cooling minimizes a building's peak electricity demand, which can result in dramatically lower electric costs.

CENTRALLY-PRODUCED CHILLED WATER

Veolia systems provide centrally-produced chilled water, pumping it into buildings for cooling and eliminating the need for customers to purchase, operate and maintain chillers and cooling towers.
 
Veolia has excess capacity at our central plants, so our customers receive the benefit of redundancy in chilled water capacity, and the economy of scale of a system designed to serve all the customers on the system.  In addition, our district energy plants and networks are designed to meet stringent environmental standards. 

STEAM ABSORPTION COOLING AND STEAM-DRIVEN CHILLERS

With the use of on-site steam absorption chillers and steam-driven turbine chillers, our customers are leveraging reliable district energy steam to supply their onsite cooling needs.  Steam cooling can dramatically reduce electricity costs and other expenses associated with peak electric demands during the summertime.  By leveraging steam for cooling versus electric-driven chilling, an estimated 50 percent of NOx emissions are reduced.  Steam-driven cooling also uses natural refrigerants, eliminating the need for CFC or HCFC refrigerants – mixtures used in the refrigeration cycle that are attributed to depleting the ozone.  

CUSTOM STEAM COOLING SOLUTIONS

We have worked with our customers on the installation of several types of steam-cooling systems, including:

  • Steam turbine-driven centrifugal chillers
  • Single stage absorption chillers
  • Two-stage absorption chillers
  • Steam turbine generators that produce electricity and then exhaust into steam chillers, producing electricity and chilled water

     

REPRESENTATIVE NETWORKS

Baltimore, MD
  • 240 customers
  • 38,550 tons of chilled water capacity
  • 40 million ton-hours of low-temperature chilled water cool more than 11.5 million square feet of conditioned space
  • Home to one of the largest ice thermal storage systems in the country

BENEFITS

In a District Energy system, a central plant produces hot water, steam or chilled water and delivers it to a group of buildings or facilities via an underground piping distribution network.

Customers:
  • Typically experience over 99% availability
  • Demonstrated reliability to support mission-critical requirements
  • Eliminate capital costs, interest payments, property taxes, insurance costs, and maintenance contracts for new in-building heating and cooling systems
  • Preserve space, avoiding large mechanical rooms
  • Increase in revenue-generating space (removal of mechanical rooms for boilers and chillers)
  • Improved safety of operation and lower insurance rates by removing on-site fuel and chemical storage
  • Avoid equipment maintenance and lower your ongoing operating and maintenance costs
  • Minimize labor and administrative costs
  • Transfer energy, operating, and environmental risks to Veolia 
  • Potential points for LEED and ENERGY STAR certification

Veolia:
  • Assumes operating risks
  • Complies with stringent environmental rules
  • Invests in technology for your benefit
  • Representative Networks
