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.
As one of the world’s most versatile building materials, with a wide range of esthetic options and outstanding energy characteristics, glass provides numerous opportunities to enhance buildings’ visual appeal and performance.
The recognizable inclined tower at Montréal’s Olympic stadium, vacant since 1987, has undergone a makeover to better suit new tenants. Designed by architect Roger Taillibert, the original Montréal Tower employed prefab concrete panels pierced with vertical strips of windows to provide the lighting suitable for its initial use of hosting sports associations.
Today, more and more architects are literally thinking outside the box. Modern buildings are taking on unique shapes and forms, and structures are reaching staggering new heights. This shift means the purpose of the building envelope is also expanding.
For decades, the words ‘design flexibility’ and ‘fire-rated glass’ would not have appeared in the same sentence. Traditional polished wired glass was the only glazing material permitted in fire-rated areas. Its network of wires holds together broken glass during a fire to slow the spread of flames and smoke longer than was previously possible with other available glazing products.
The building industry consumes 40 per cent of the world’s energy, and is responsible for more than 38 per cent of greenhouse gas (GHG) emissions, according to studies completed by the World Business Council for Sustainable Development (WBCSD 2009). The energy demand and its costs will continue to increase; this explains why Canadian building code requirements are becoming more stringent.
