Hot Water District Energy System

From 2011-2017 UBC’s aging gas-fired steam district energy system has been replaced, piece by piece, into a state-of-the-art medium temperature hot water system. The ADES steam to hot water conversion project replaced 14 kilometres of 90-year-old steam piping, and connected more than 160 buildings to a highly efficient hot water district energy system. In 2017, UBC shut the doors of its steam plant replacing the system’s primary energy source with the new 45 MWt Campus Energy Centre which, together with the distribution, improves energy efficiency by greater than 24 per cent.

The map below highlights all the buildings that connected to the new hot water grid.

Orphan Buildings

There are a handful of “orphan” buildings that won’t be connected to the new hot water system. Most of these sites are either being converted to electric baseboard, or are scheduled for major building refurbishment—with subsequent conversion to hot water—or demolition. In the meantime, buildings awaiting conversion or demolition will receive steam energy from the Bioenergy Research Demonstration Facility (BRDF).
