Structuring Sustainable Thermal Breaks: Opportunities and Liabilities
The connections of the superstructure to the foundation, slab, or the exterior systems of walls and roofs represent a transmissive bridge through the building's thermal and environmental protection system, because of the prevalent use of carbon steel ties, support and fasteners. However this common condition provides structural engineers' with opportunities to enhance the facility's energy use performance by advancing detailing to create thermal breaks. The use of lower conductance foams, wood framing, stainless steels, masonry products, etc. in the connections will be illustrated, in lieu of conventional concrete and steel juxtapositions. Design methods and case study details and specifications will be shown. Potential issues with life-safety and code interpretations or the material behavior will be discussed. With a growing understanding of building energy performance problems in the industry, the paper will attempt to encourage designers to advocate and develop a wider, varied employment of thermal breaks on each project.
