R values and insulation performance
Efficient home design

Understanding thermal performance

...wall assemblies and insulation products has long been characterized using R-value, a metric which describes thermal resistance. While R-value is useful, it doesn’t tell the whole story about heat flow through building enclosures such as walls and roofs. Recently, a study by RDH Building Engineering Ltd . h as shown t...

...wall to give the required clearance underneath, or trim the carpet down around the base of the heaters. If the air can’t circulate, then they can’t heat or cool efficiently. Close proximity to something combustible like a carpet can also cause premature failure, or worst-case scenario in electric ones, a fire. Incorr...

...wall of the dam. Would you choose the height of that concrete wall randomly, or would want an even level of concrete to hold back as much water as possible? You certainly wouldn't want an extremely high wall on one side and lower on another; the relationship between heat movement and insulation is a bit like that. Th...

"The Most Resilient House in North America"

A resilient home for Sustainability Northern Quebec isn’t a place where one might expect to look for a model of resilience . It’s bone-chilling cold in the winter with 10,450 heating degree days per year (Fahrenheit degree-days, base 65°F); there isn’t all that much sunlight in the winter, and Quebec—let alone north...

Choosing where to live

What makes a home livable to you?

...efficient living. If we must live smarter and smaller in our changing urban environment, as an architect, I ask myself, how do we design spaces to support people through this shift? Well, we start by asking the question: What makes a home livable? This query sparked the Livable Homes initiative launched by Perkin...

...wall drying abilities means that this house will have a longer than average operational life. This will help balance the added 'carbon' investment in terms of the embodied energy of building materials. For our building envelope we will use Roxul mineral wool insulation, which has a high embodied energy but superior d...

When should you replace old windows?

...wall itself. There is also air quality issues to consider as you may have mold and mildew as well. In such a case you may be wise to replace an individual window. The problem here is of course the 'slippery slope', in that replacing only one window on a wall may stand out, and replacing the windows on only one wall o...
