Blatchford Neighbourhood District Energy System - Phase 1

The largest application of an ambienttemperature, energy distribution system in Canada, Blatchford’s innovative District Energy Sharing System allows for efficient use of heat pumps and integration of other low-temperature sources. Energy is shared between buildings rejecting heat and those requiring it. Communication was critical to successful project delivery and community acceptance. Supporting city communications helped to alleviate Council concerns and garner public buy-in. The design and scale of the project posed potential risks. Associated’s team analyzed design options, and identified and mitigated risks without impacting development timelines. Geoexchange test drilling and conductivity testing were completed to develop a site-specific, Please explain why you think this project should receive an award? 570 borehole field design. The geoexchange system involved design and construction of a large and complex piping system. The threekilometre distribution piping system (DPS) consists of two-pipe (supply/return) fusionwelded, high density polyethylene pipe, up to 600 millimeter in diameter. To facilitate construction, the DPS is largely collocated with other major utilities. Phase 1, including the 3 megawatt Energy Centre One plant, DPS, and GHX field, had to be commissioned before the homes could be occupied. The team employed a quality-based selection approach for the contractor and a construction strategy that resulted in the commissioning of the energy system on time.
