Smarter Skins 2 for Higher Performance Buildings

0

CertainTeed is pleased to introduce Building Knowledge insights that are focused on the Canadian market.  This is the second blog published by one of our Canadian experts.

There is a push globally for all building codes, including at the international level, towards net-zero construction by 2030.  Europe, which is somewhat ahead of the rest of the world in energy efficiency, in pushing for mandatory zero energy requirements by 2018.

Canadians are experts in adapting to cold extremes, developing performance codes and innovative Building Skins solutions and, therefore, have many insights when it comes to achieving this goal. Accordingly, Toronto (See my previous Blog) and Vancouver are two of the top energy efficiency leaders in buildings in North America.

I had the opportunity to share building science insights to several hundred architects at Building Industry events in Vancouver and Toronto. In Toronto, the Ontario Association of Architects (OAA) are leaders with their own OAA+2030 program and I had the chance to co-present with a leading Architect, Contractor and University Team; the Smarter Skins 2 sequel in 2015 (SS 2015).  We know it was successful; as Smarter Skins 3 is already planned for 2016! What are some of the smarter building skin solutions from SS 2015 that contribute to higher performance and most important provide sustainable habitat for building occupants?

SS 2015 presented the key principals for building smarter skin solutions including a case study from the CNN eye-popping and award winning New Halifax Library.

What is the principal lesson learned for large glass buildings if we also want to achieve higher performance?  It is the need for better architectural design that includes Building Science principles.  In the case of the Halifax Library, behind the glass skin veneer 54 percent of the walls are opaque walls constructed with insulation and drywall (See sample detail).  Therefore, by focusing on smarter wall and window assemblies, you can have inspirational views to the harbor and higher building envelope performance at lower cost.

In summary, design and build with smarter skins and your customers will come.  The recently opened Halifax Library has been experiencing Community usage approximately two times greater than expected and patrons are being inspired by the views to advance their knowledge.  Blog readers can also benefit from more Smarter Skins Higher Performance Buildings insights by following My Blog and attending CertainTeed’s  Architectural Insights Symposiums and Industry Partner Events that share smarter skins knowledge.

If you are working on creating smarter skins for all types of sustainable buildings, I would be interested in hearing about your projects and the materials and system skins you are using. For example, smarter skins are essential for more affordable mid-rise wood buildings now permitted in most Canadian Codes. Together, with Smarter Insights, we will achieve higher performance buildings today for our customers and move toward the goal of Net-Zero Energy.
