Enwave Deep Lake Water Cooling Network

An increasing number of buildings in Toronto's downtown are clients of Enwave's Deep Lake Water Cooling system, which uses water from the depths of Lake Ontario to drive a heat exchange system that provides cooling for large buildings like office towers and hospitals. Unsurprisingly, no real effort has been made to show people who live and work in the city what this system actually looks like, and it isn't the abstract network portrayed in the bare bones public information that the company has released. Much like our sewer systems, the Enwave system consists of a connected series of real, human-scale spaces and architecture that provide access for the expansion, maintenance, and management of the system, but are at the same time clearly constrained by a particular set of engineering choices and by the built environment that already surrounds them.

The gallery and interactive map on this page shows the distribution tunnel system that connects Enwave's cooling plant buildings to its customers throughout the downtown core. Elsewhere, I have published articles detailing the construction of this distribution system and the shape and possibilities of the cooling plants themselves.
