Energy efficiency in existing buildings

As Canada's economy grows, so too does our built environment. As we continue to shift toward a knowledge-based and service-oriented economy, the share of the commercial and institutional buildings will follow.

Statistics show that between 1990 and 2010, the commercial buildings sector grew by 22 percent. Buildings in this sector used roughly 1,057 petajoules of energy, or about 12 percent of Canada’s energy use.

In most commercial buildings, most of that energy is used for lighting, heating and cooling, motors for large equipment such as elevators, and water heating.Footnote 1

The Office of Energy Efficiency has programs, tools and other resources you need to benchmark your energy performance, recommission your building, and train your staff to achieve your energy - and cost - saving goals.

Improve energy efficiency using a whole-building approach

Most buildings are upgraded bit by bit as their components age and need repair. Often, a better way to improve energy efficiency is to use a whole-building approach and take advantage of the opportunity to implement deep retrofits. The upfront cost may be more, but the potential long-term savings will be greater over the life of the building.
