Alberta Context:
This tool was created in Western Canada and some of the details lend themselves to Alberta design and construction. Its utility extends to projects within Alberta, given that thermal bridging calculations remain consistent across the country. The only variable is the Heating Degree Days (HDD), which differ across climate zones and locations.
Summary:
With the requirement of calculating effective R-values in the new building energy codes, the Building Envelope Thermal Bridging Guide is a good initial resource for understanding the underlying methodology of thermal bridging and conducting detailed thermal transmittance calculations tailored to specific projects.
The website tool offers a printable guide and video modules to assist. Additionally, the Zero Emissions Building Exchange (ZEBx) developed a Playbook titled “Dealing with Thermal Bridging in Net-Zero Energy-Ready Building Design” which provides insight into addressing thermal bridging during early design stages and effectively mitigating it for net-zero energy-ready buildings.
