Metering Matters

In June 2006, CSE took a look at how the city of Toronto has capitalized on a valuable asset lying 272 ft. below the surface of Lake Ontario—icy cold water that remains at a constant 39.2ºF all year round. Since August 2004, this previously untapped resource has been supplying economical and environmentally friendly air conditioning to large buildings in the city's downtown.

We return for another look at The Deep Lake Water Cooling (DLWC) system in Toronto, this time to consider how metering plays a significant part in this system. A case study from Krohne, Toronto, describes how “instead of buying electricity to power their own cooling system, customers outsource the process to a district cooling operation. They receive cooling energy in the form of cold water and they need only distribute that cooling energy within their building.” Customers are billed by calculating energy consumed, based on the water flow and the temperature differential between the customer's supply and return lines.
