CASE STUDY WHISTLER OLYMPIC VILLAGE
GAINS T
Olympic
More than 2,000 athletes at the 2010 Winter Games in Whistler were kept warm by heat extracted from an existing sewage treatment plant. Richard Perry and Tom Ren look at the legacy of their heat network design, and reveal how the project achieved 50% savings in energy use
he Olympics aren’t just about the athletes. For the hosts it is an opportunity to put their cities on the map, and create a string of world-
class new sports venues. New buildings help leverage investment in new infrastructure, giving local authorities the chance to create more effi cient and cost-effective methods of providing energy. One town to benefi t from an Olympic legacy is Whistler in Canada, where a heat-

recovery plant was installed to extract energy from a sewage waste treatment plant. The network was used to provide heating and cooling for more than 2,000 athletes and coaches at the 2010 Winter Games. Post- Olympics, it provides energy for hundreds of homes. The system consists of a central service building, which houses circulating pumps, heat pumps and boilers; a distribution network; heat pumps in each of the residences; and connected heating, cooling and domestic water-heating systems. Designing the Whistler system was extremely complicated because of the variability of both the energy source and the residential demands. Further complicating matters was the need for the system to perform in a cold climate. The buildings in Phase 1 have been converted for residential use and have been in operation for more than a year, during which time the connected systems have been monitored on an hourly basis and the results documented. The primary energy source for heating, cooling and domestic hot water is the district
