This is the BEST3 Conference paper. The DVD will follow soon. Its working title is  “Skylight 101, or what you have always wanted to learn about sloped glazing.” It presents typical challenges and solutions associated with sloped glazing and skylights, presents a history of development of sloped glazing, different classifications, including the one developed by the author on basis of the air barrier location, types of internal and external drainage of sloped glazing, structural challenges typical sources of failures, applicable construction testing procedures, code compliance, maintenance access to the sloped glazing, safety standards, challenges involved in obsolete code interpretation as related to the modern glazing, analyses of frequently misunderstood details, examples of correct details, and energy ramifications of sloped glazing. Case examples will include typical cases of leakage, condensation and icing, thermal simulations of skylight, as well as a structural collapse of a monumental sloped glazing. This paper focuses on areas typically overlooked by architects and engineers in process of building envelope design. The topics are chosen on basis of observations derived from both forensic investigations of failed assemblies and peer reviews of architectural documentation.
