A new report by international engineering firm Morrison Hershfield guides architects and engineers to stop thermal bridging that reduces overall energy consumption in buildings.

Thermal bridges are spots of high heat flow through building exterior such as roofs and windows. Thermal bridging is created by highly conductive elements that allow heat transfer inside the building, which significantly reduces the energy efficiency of the overall structure.

Although the impacts of thermal bridging have previously be viewed as minimal, research shows total heat flow through walls is commonly underestimated by 20 to 70 percent.

The new guide to combat thermal bridging explains the importance of reducing heat transfer between the interior and exterior of buildings and offers solutions to lessen the impacts of thermal bridges. Included in the guide are suggestions for improvements to the building envelope that consider building codes and the cost-effectiveness of doing so.
