Fire Truck Fire Hall

Vaughan Fire Hall No. 7‐10

10800 Dufferin St., Vaughan, Ontario

This state-of-the-art facility has been designed for LEED Silver accreditation. The HVAC system of this building consists of highly efficient split‐type units with advanced controls to ensure system efficiency.

  • The fresh air delivery to this building is by way of heat recovery ventilators that take what would be wasted energy from washroom exhaust air and transfers it to the incoming fresh outdoor air.
  • All plumbing fixtures are of low‐flow type and significantly surpass the efficiencies of the LEED baseline case.
  • Domestic hot water is provided through highly efficient on‐demand gas‐fired heaters that eliminate wasted energy typical of conventional hot water storage systems.
