Building Air Leakage energy control module

This page was developed by the Queen's University Applied Sustainability Research Group.

Air leakage can contribute to large amounts of energy waste within a building. Conditioned air may be lost, increasing the load on the chiller/boiler unit. Often, small preventative measures can be taken which are cheap and ease to implement and greatly reduce air loss.

Doors and Entrance Ways

• Door seals (condition, existence)
• Door closers (existence, condition)
• Door Type (construction, age, condition, number)
• Building pressure differential <-
• Local wind conditions (vestibule usage) <-
• Average pedestrian traffic <-
• Abandoned doors (usage prevention, number)

Industrial Doors

• Door seals (condition, existence)
• Door Type (construction, age, condition, number, size, insulation)
• Powered door operator (control, design, operator linkage)
• Loading docks (inter-vehicle/building seals)
