For the past 50 years, the commercial roofing industry in North America has developed and adapted many roofing system options for low-slope buildings. Modified bitumen (mod-bit) membrane assemblies are well-suited to the Canadian climate, making the system a significant player in the commercial roofing marketplace.
Space-heating accounts for more than 60 per cent of the total residential energy consumption in Canada, but for the coldest parts of the country, it represents more than 70 per cent of the total household energy use.
Use of two-pound, medium-density closed-cell sprayed polyurethane foam (SPF) is growing rapidly in commercial structures. Utilization of the material has been fuelled in large part by its ability to seal the structure and, in doing so, tremendously enhance energy efficiency.
Government regulations requiring co-ordinated changes to manufacturing, design, and construction practices with a single regulation are difficult for the industry to assimilate successfully. The banning of solvent-based adhesives was one such example.
Hot water is the lifeblood for many commercial applications. A restaurant lacking hot water will be forced to shut down for lack of hygiene. Hotel room showers that cannot reach the set-point temperature leave clients dirty and disappointed.
Balloons evoke childhood memories of a trip to the circus or a day spent at a local amusement park—the air that fills them is fundamental to life itself. Ironically, the same air that brings ‘life’ to a balloon (and us) causes headaches or worse for building owners, architects, and specifiers.
Advances in light-emitting diode (LED) technology mean facilities no longer need to accept lighting elements that are difficult or expensive to maintain. LED fixtures have become increasingly affordable on the front end, especially when combined with utility rebates.
As a child in the early 1980s, this article’s author had a clubhouse he called the ‘Millennium Falcon’—standing 2 m (6 ft) off the ground, it was a simple A-frame held in place by four old telephone posts, complete with a fireman’s pole and pully system for escape when under attack by the Imperial Starfleet.
Given their extensive use of energy-hungry medical equipment and around-the-clock service to the community, hospitals consume huge amounts of power. These buildings rank as Canada’s most intensive energy-consumers, second only to food and beverage stores.
