Sloped Glazing: Challenges and Solutions
This session presents typical challenges and solutions associated with sloped glazing and skylights, 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. Many designers and builders treat sloped glazing as it were a tilted curtain wall. However, this proved to be one of the most challenging assemblies, seldom fully understood by their own manufacturers, fabricators, and installers, as well as building enclosure consultants.
This may be well illustrated by the fact that rain water leakage of sloped glazing is as unique as it is widespread;
it's unique among other leakage cases because the source and location of a leak may often be obvious; however, it still requires a thorough expertise to understand the mechanism and devise a fix. It's widespread because many glazings were designed and built wrong from the start, and botched glazings have often successfully resisted multiple investigations and repair attempts. This seminar 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.

Karol Kazmierczak CDT,LEED-AP, NCARB, Senior Building Science Architect at Building Enclosure Consulting
Mr. Karol Kaźmierczak (Kaz) M.Sc. is a facade physician and a senior building science architect with 20 years of façade engineering experience diversified among building enclosure technical design, consulting, construction inspections, diagnostic testing, and field investigations.
Kaz bridges the traditional gaps among the mechanical, structural, and architectural disciplines, and between the design and construction due to his specialized European façade engineering experience, architectural education, and a strong field presence. He no longer practices facade engineering; instead he practices MacGyver engineering by developing custom procedures and tools to diagnose failures of existing buildings.
He specializes in high-rise buildings, and has been involved with facades of over 400 buildings located on two continents, in various climates. Kaz designs, engineers, reviews, and investigates high-rises, analyzing failures and damages, monitoring construction in progress, and producing calculations, analyses, and computer simulations, and drafting systemic and interface details. His technical design contributions to many innovative, cutting-edge, high-rise cladding projects, including unusual combinations of materials and systems, double curvatures, smart double skins, intelligent shading, and whole-glazing facades gave him the unique perspective of curtain walls.
Kaz is a registered architect in New York and Florida, carries CDT and LEED-AP certificates, speaks publicly, and writes articles on subject of building enclosures.
