Heating & Cooling

Heating and cooling are two of the major energy uses in buildings in Canada and the production of the energy required for these operations can have considerable impacts on climate change.

At Local Government House

Given Victoria's moderate climate, Local Government House does not have a mechanical cooling system. Instead, the building features an opening skylight and light well that connects the main and second floors. The skylight is equipped with a reversible fan that pulls warm air out in the summer and re-circulates warm air to the main and second floors in the winter. It can also be tinted to limit the amount of sun entering the building on warmer summer days.

The green roof and green walls act as natural temperature regulators, helping to keep Local Government House warm in the winter and cool in the summer, and reducing the heat island effect associated with conventional buildings. They also provide habitat for birds and insects.

Heating is provided through a combination of radiant ceiling tiles and radiant floors that are warmed by the circulation of hot water. A natural gas fired, energy efficient boiler is installed in the basement to provide the required hot water for both space heating and hot water. The boiler operates at a higher efficiency than instantaneous water heaters and has stainless steel heat exchangers - which have double the lifespan of the copper fin heat exchangers found in instantaneous water heaters. Offices are equipped with thermostats and opening windows to allow personal temperature control.

In Your Community

  • Consider options for geo-thermal or geo-exchange heating for local government buildings and in local developments.
  • Work with developers to consider green walls, green roofs, day lighting and other site orientation opportunities to maximize natural opportunities to heat and cool buildings.
  • Look for reduced heat island effect in local developments: providing on-site shaded areas or moving parking to underground locations are two good starting points.
  • Consider options for solar, solar thermal or wind generated energy to operate heating and cooling systems.
