Since roll-formed and laser-welded steel methodology is relatively new for curtain walls, this article addresses three relevant inaccuracies as they relate to Canada’s snow-laden winters, subarctic temperatures, and the Leadership in Energy and Environmental Design (LEED) v4.1 goals.
The new 707 Fifth AAA office tower in downtown Calgary features a distinctive, curved glass appearance and creates a high energy-efficiency workspace with a triple-glazed, curved glass curtain wall system.
The Building NX retrofit at Humber College, Toronto, has been awarded the Zero Carbon Building—Design certification by the Canada Green Building Council (CaGBC). It is the first retrofit in the country to achieve this certification.
CSC Vancouver Island is holding a luncheon meeting to discuss “The Past, Present, and Future of Curtain Wall.” The presentation will take place on Thursday, May 9, from 11:30 a.m. to 1:30 p.m. at the Fireside Grill.
In cold climates, condensation-resistance performance is expected for standard curtain wall systems. However, occupancy factors, unconventional building geometry, design details, and the design of heating systems and interior finishes may result in the reduction of condensation resistance, as demonstrated by a case study of a 12-storey commercial building in Montréal.
Low-iron jumbo glass with low-emissivity (low-e) coating was used during the retrofit of the National Arts Centre (NAC) in Ottawa. High-performance glass brings in abundant natural light and controls solar heat gain, thereby contributing to energy management while ensuring the open spaces at the NAC do not overheat.
