As part of the award-winning community of Wesbrook Village, Eton offers a collection of spacious 1, 2 and 3-bedroom residences in a choice of high-rise, mid-rise and townhouse configurations; with views of the Georgia Strait and surrounding nature at its finest. Just steps away from Pacific Spirit Park, Eton provides easy access to University of British Columbia’s main campus, as well as family-oriented schools, shopping opportunities and leisure activities.
Williams Engineering Canada (WEC) supplied mechanical design services for the Eton Tower. Boasting a District Energy (DE) connection as its main heating source, this fully air conditioned project utilizes vertical stacking hybrid heatpumps that provide direct contact hydronic heating, while utilizing a water cooled compressor to generate the necessary cooling for each suite. This permits the use of an economical single hydronic piping system; operating temperatures are controlled via direct digital control (DDC) to ensure loop temperatures do not exceed the operating range of the hybrid heatpump unit. A fluid cooler, located on the roof of the tower, rejects any excess heat from the system. Fresh air ventilation requirements are achieved by an insulated outdoor air duct connected directly to the return inlet of each hybrid heatpump, coupled with a continuously operating system fan to circulate air to all regularly occupied spaces within each suite. The energy for generating domestic hot water is also received from the DE system via a series of direct contact plate-and-frame heat exchangers serving the street pressure and the boosted pressure distribution zones. Domestic hot water storage tanks are utilized to address peak loading conditions, permitting the heat exchangers to be more economically sized for most of the load.
Eton is one of the many residential developments on the UBC campus that WEC is proud to have contributed to. Sustainability continues to be a top priority for UBC and aligns with WEC’s vision of providing sustainable design and innovative engineering services to our clients. Construction is expected to be complete by the winter of 2018.
