Projecting facade elements -- or those that project out beyond the normal plane of the thermal envelope such as parapets, overhangs, and wing walls -- are difficult details to design for and oftentimes create performance issues, such as condensation in wintertime conditions. In this presentation, various parapet, overhang, and wing wall configurations will be discussed, including problems that occurred and detailing solutions. Items such as thermal bridging, thermal shorting, ventilation, flashing, and air leakage sites will be reviewed using actual details for buildings in cold climates. One case study presented will include a new Chicagoland healthcare building, where the three presenters – a BECx Provider, a facade consultant, and a general contractor – together helped to resolve the challenging detailing conditions.
- Identify projecting elements that have increased risk for condensation
- Understand how air leakage, thermal bridging, and thermal shorting at projecting elements creates risk for condensation
- Understand that there are two different general concepts for detailing projecting elements
- Identify various ways to minimize risk for condensation in projecting elements
