A curtain wall is a cost-effective building exterior enclosure system, and can be an esthetically pleasing envelope for many building types. From high-rise residential to office buildings, glass curtain wall cladding can provide architecturally eye-catching and highly marketable views for occupants. However, it is not an exterior cladding normally associated with high thermal and solar gain performance for reduced building energy use.
When most people think about installing hardwood floors, they typically envision a hammer, nails, and a lot of backbreaking work. However, the reality is there are several options available for installing wood floors. Choosing the most appropriate method depends on the flooring type, whether the floor will be installed above or below grade, and the type of material employed for the subfloor.
It is no surprise recording studios and radio/television broadcast studios are among the most demanding acoustic environments. They are precisely tuned to achieve the optimal acoustic effects, such as background noise elimination, delivery of clear, crisp speech, absence of echo, and precise use of reverberation.
Co-ordination is the basis of specifications, an aspect of its principal functions, and one of the spec writer’s primary tasks. It manifests itself at various phases of the writing process, as well as within different parts of the project manual itself.
Contractors who deal with condominium corporations should be aware of recent reports in the press of a case involving alleged construction fraud and mortgage fraud perpetrated by a property manager. The story of the $20-plus million fraud was first reported by The Toronto Star in September 2011. The number of condominium corporations affected by the alleged fraud now stands at nine and counting, and police are continuing their investigation.
The finishing of ceilings quite often takes a backseat to many other esthetic categories like flooring and trimwork. Nevertheless, by overlooking the ceiling, one may be missing out on a significant architectural and decorative aspect of the project. In terms of a visual ‘look,’ the ceiling can be just as important a design item as the flooring.
Green roofs are continuing to gain recognition as a sustainable building design feature throughout North America. These vegetated assemblies contribute to many credits under the Canada Green Building Council’s (CaGBC’s) Leadership in Energy and Environmental Design (LEED) program.
To ensure performance of these systems, the Single-ply Roofing Industry (SPRI) association has passed two design standards and a test procedure specific for vegetative roofs in the last couple of years.
Cold-formed steel framing (CFSF)—also known as ‘light-gauge’—began as a kind of alternative lumber, but after decades of positive performance it has finally come into its own. Much like wood worked by carpenters, steel studs and track can be cut and combined to create more complex shapes.
Design/construction professionals working on single-family residential projects are facing diametrically opposing forces––the need for energy efficiency, environmentally sensitive construction, and macroeconomic demand for lower construction costs. As specifiers aspire toward a ‘net-zero-energy’ home, with a price tag currently out of reach for most Canadians, this author discusses what can realistically be achieved at an affordable price for a typical Canadian home.
The Canadian government recently suggested energy efficiency is an important tool for addressing climate change, promoting economic activity, and supporting energy security. Further, it says Canada will aim to reduce greenhouse gas (GHG) emissions by 17 per cent below 2005 levels by 2020.
