The Québec City Convention Centre
The Québec City convention centre is a six-storey commercial building. It was erected in 1996 and then expanded and partially renovated on two occasions. Although primarily focused on conventions, the facility also hosts artistic events, concerts, etc.
As the types of building occupancy are quite varied, major fluctuations in electricity consumption were expected. As a result, the CCQ installed an electric boiler (1 MW) and a heat accumulator controlled by a deballasting system. This drives down electricity use and reduces greenhouse gas production since the three other boilers run on natural gas (250 HP each). On an annual basis, the electric boiler meets 50% of the demand for heat, with the gas boilers supplying the rest.
Additional efforts were made to reduce the CCQ’s environmental impact in connection with LEED certification, in particular by acquiring alternative materials for operation and maintenance activities.
