Until December 9, members of the public are invited to review proposed changes to Codes Canada 2015 publications, including national building, fire, plumbing, and energy codes. This first review round has a primary focus on the National Energy Code for Buildings (NECB) and National Plumbing Code (NPC).
The lighting industry has recently been the site of substantial change, as demand for intelligent light-emitting diode (LED) systems and controls is beginning to transform workspaces. Despite the benefits (e.g. cost-effectiveness and compatibility with wired and wireless controls) this advancement brings, it is creating an education gap among industry professionals.
Insulation manufacturers have devised numerous ways to improve the thermal performance of their products, from adding specialized particles to polystyrene to refining vacuum insulated panels (VIPs) and phase-change materials to aerogels. Unfortunately, none of this matters when these high-performance products are installed ineffectively.
During the 1970s, extensive research was carried out in Canada on air leakage in buildings. Researchers at the National Research Council (NRC) demonstrated the importance of managing air leakage through the building enclosure. In the following decade, the concept of air barrier material emerged and was formally introduced in the 1985 edition of the National Building Code of Canada (NBC).
The term ‘thermal movement’ refers to a material’s dimensional changes resulting from temperature swings. A material experiencing a rise or decrease of temperature expands or contracts, respectively—this poses an interesting challenge when it comes to designing metal panel roof assemblies.
Canadian energy codes will never be less stringent than they are today. Therefore, it is important to have a firm understanding of the building options available to achieve and outperform regulations. Contrary to some conventional thinking, a ‘systems’ approach to construction can prove an ideal building approach even when high thermal performance is required.
Steel has long been praised for its strength, durability, and functionality. More recently, architects and engineers have recognized the material’s additional sustainability advantages, particularly its high recycled content and end-of-life recovery rate.
Greg Clemens, FCSC, RSW, CCCA, MAATO, a member of CSC’s London Chapter and an editorial advisor for Construction Canada magazine, passed away on October 25, 2016.
