Thermal Performance of Spandrel Assemblies in Glazing Systems Research Roadmap, Phase 1

Thermal Performance of Spandrel Assemblies in Glazing Systems Research Roadmap, Phase 1

The current state of practice for evaluating spandrel assembly thermal performance is lacking, and analytical approaches are inconsistent. Building codes and standards are also inadequate, leading to variable design execution on projects. While energy codes have become more stringent, spandrel assembly technologies have largely remained the same. There is a need for improved design guidelines, to bring consistency to calculation methods, to identify opportunities to improve materials, details, and systems, and inform future code provisions. This is Phase 1 of a four-phase research program to produce a Design Guidance Document. Phase 1 - Design Test Program jump starts this effort by conducting a literature search of available information on the topic, a survey of stakeholders to understand the scope and prevalence of different spandrel systems, an energy study, a Computational Fluids Dynamics analysis to explore cavity airflow impacts as well as the specification of the test program to be conducted in subsequent phases. This research is conducted by the team of Simpson Gumpertz & Heger (SGH), Morrison Hershfield (MH), and RDH Building Science, Inc. (RDH).
