IRC's work on thermal environments in atriums is assisting Ogilvie and Hogg Architects to design an improved atrium skylight system for the Bank of Canada's head office building.

The current system requires replacement because of a history of breakage, leakage and numerous repairs. Condensation problems, for example, have damaged the paint and gypsum board below the skylights.

IRC's contribution involves winter and summer field measurements to analyze the condensation problem and investigate the atrium's thermal conditions as they affect comfort, plant growth on the atrium floor, and condensation on the skylight.

Findings so far indicate opportunities to modify the HVAC system to decrease condensation and frost formation on the skylights.
