Whether for new construction or re-roofing, there are many considerations involved when designing a roof. Numerous design nuances and issues exist that—when overlooked—can detrimentally affect both roof performance and ease of project completion. This presentation will provide an overview of critical items that many designers may not be aware of, but which should be accounted for when designing roof assemblies. These critical items run from simple wording within specifications sections to how the roofs are tied into other building envelope…

Most of the recent developments in Building Science have resulted from expensive monitoring of building assemblies in laboratory conditions. In the last decade, cost-effective instruments have become available that permit monitoring assemblies in situ. Through the data collected, practitioners can better understand the microclimates that are created when components join together in building assemblies. This luncheon will examine data collected in the field to suggest a cause for horizontal cracking of stucco applied on steel furring. A conceptual solution that…
