The Well Community
Along Spadina Avenue, work is progressing on one of the largest construction sites in Ontario. Spanning over seven acres from Front Street to Wellington Street, The Well will feature three million sq. ft. of residential, entertainment, retail and workspace; all within one spectacular new community in the heart of downtown Toronto. It is the most ambitious mixed-use community currently under construction in the City of Toronto.
This vision extends beyond what will meet the eye once the buildings are completed and the homes and businesses occupied. Careful planning and forward-thinking design will ensure The Well becomes not just a destination address, but an integral part of the city’s fabric.
Enwave’s Well Beneath The Well
As the residential, commercial and retail buildings rise around it, one section of The Well includes the excavation of a deep cistern near the centre of the site. Though still under construction, the top edge of the cistern already sits 150ft below ground level and is designed to go even further. Just past the guardrail, currently 100ft down, there are two excavators breaking rock to be hauled off-site. Despite the depth, the team is just only two-thirds of the way through their work. Once complete, the well will be 260ft deep and be situated only 14m above sea level.
Sustainable Heating & Cooling Design
The cistern will connect to the Enwave Deep Lake Water Cooling (DLWC) system to provide heating and cooling to the 11,000 people who will live and work at The Well. Deep Lake Water Cooling (DLWC) is a heating and cooling solution that harnesses the renewable cold temperatures of Lake Ontario. Pipes pull water from deep within Lake Ontario then filter and treat it, before then going through a heat exchange process at the John Street pumping station. The process feeds into both to the Enwave system and filtered drinking water distribution system to Toronto residents. The cold water goes into a cooling loop for air conditioning. The heating loop uses electricity to turn the water into steam. Condensation from the heating loop is recycled. 
DLWC is a renewable, sustainable heating and cooling system for buildings interested in their environmental footprint and reduced costs. Benefits to the residents using the Enwave system include lower building maintenance costs as the building will not require the purchase, installation, maintenance and eventual replacement of expensive heating tanks and cooling towers. The system is inherently more energy efficient than traditional air conditioning and heating methods. Environmentally, compared to an in-house chiller, Deep Lake Water Cooling uses up to 90% less electricity, eliminates ozone-depleting emissions, and primarily uses renewable lake water. 
Designing For Well Beyond The Well
At present, the Enwave system offers services as far west as the Rogers Center. The construction of this new cistern at The Well will also serve as the hub of future expansion, allowing Enwave to offer this sustainable energy source to more customers, as the city develops. The goal is to create the necessary infrastructure to offer Enwave services to customers west of The Well as development in the Toronto core continues to grow.
