Campus Energy Loop

Portland State University’s “Campus Loop” is a district energy system that provides heating and cooling to multiple buildings in the core of campus. Centralized locations generate steam and chilled water which are distributed through a network of pipes to connected buildings. As a result, each building does not require individual boilers and chillers.  The campus energy loop benefits the University is several ways: 

  • Increased energy efficiency and lower utility costs
  • Reduced carbon emissions and pollution footprint for the University, due to lower quantities of natural gas and refrigerant gasses needed
  • Minimized outages due to system inter-connectivity
  • Lower lifecycle costs through reduction of materials used, maintenance, and building capital costs
  • Increased flexibility to convert to a more efficient fuel source if one becomes available
  • Ease of operation and maintenance due to central location
