Office buildings account for just over one-third of all energy used in the Commercial and Institutional sector in Canada. This significant share of energy use is only partly attributed to base building operating systems. The remaining share of energy consumption is a result of tenant systems and processes which include space heating (49%), auxiliary equipment including electronics (16%), lighting (10%), space cooling (7%), water heating (9%), and auxiliary motors (8%).
TD Centre recognizes that opportunities exist to continually find opportunities for reducing energy use in these areas.
A major lighting retrofit has been completed across TD Centre, relamping existing base building light fixtures with more energy efficient bulbs that use significantly less energy, reducing energy use by a projected 3.5 MW annually - the equivalent of 35,000 tons of carbon dioxide emissions.
Sub-metering systems are installed on every floor of the TD Centre and allow a tenancy to view its specific energy use, allowing operators and tenants to identify opportunities for conservation and efficiency quickly.

Deep Lake Water Cooling
In 2004, the TD Centre converted to Enwave Deep Lake Water Cooling, resulting in the replacement of 13,000 tons of chiller capacity and, in turn, reducing electricity consumption by 90%. This has resulted in 23,000 tons of CO2 emissions avoided annually.

Energy Innovation Team
The Energy Innovation Team at the TD Centre is comprised of building operators, building engineers, sustainability consultants and equipment suppliers, with a primary focus of managing energy at the property. Innovative solutions identify energy conservation measures, operational improvements and the development of corresponding action plans centered on achieving low energy and reduced GHG intensity for the property.
