Designing buildings for climate change

Canada’s building codes have historically been formulated, at least in part, based on accumulated historic climate data that ultimately provides the essential criteria for most key building component performance characteristics. However, there are indications climate may be beginning to change. If buildings do, in fact, experience different environmental conditions over the next 40 years, these changes could potentially have a significant impact on our building stock.

The effect of temperature on insulation performance

On the surface, R-value is a simple thing. In fact, it has become the standard metric of thermal performance precisely because it is easy to explain and understand. Most insulation materials have ‘label R-values’ stamped on their faces (or at least displayed in large print on the packaging), but these values do not tell the whole story of how insulation performs in service. Some complicating factors—such as thermal bridging—have become fairly well-known.

The importance of specifying a metering faucet

When it comes to faucets in commercial or institutional buildings, there are considerations specifiers should keep in mind for the right outcome—in other words, saving water without sacrificing performance. Besides every project being different, each type of facility has its own unique requirements. There are the water conditions, local codes, performance characteristics of the faucets, and a wide range of other variables that range from owner or contractor preference to material availability.
