Many existing buildings were constructed before current energy and building codes required a continuous air and vapor barrier, and exterior insulation. In an effort to improve the thermal performance and interior air quality of these facilities, many building owners are looking to upgrade their existing infrastructure. The presenter recently completed evaluations of several existing higher education facilities with a focus on improving the exterior building enclosures. The presentation will provide an in-depth examination of design considerations with a focus on addressing ongoing air and moisture infiltration caused by the lack of continuous air barriers and thermal insulation. The presentation will discuss unique solutions to improve the overall building performances and aesthetics, and coordinate construction in an occupied facility.
