The Province of British Columbia, through the Building and Safety Policy Branch, has made changes to the BC Building Code that allow for the construction of wood frame structures for up to 6 stories.  This change from 4 to 6 stories introduces additional complexities for the design and construction team particularly with respect to the structure, fire protection systems and the building enclosure. The Association of Professional Engineers and Geoscientists of British Columbia (APEGBC) received funding from the Province to…

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…

There is a lack of understanding in the building envelope industry on legal issues arising from Warranty Reviews and 2-5-10 Year Warranty Claims. John Mendes will present on legal issues arising from 2-5-10 Year Warranty Claims with a focus on end-of-warranty reviews by consultants. This presentation will also provide an overview of some legal issues pertaining to building owners arising from the warranty reviews and claims. John Mendes is a partner of Lesperance Mendes Law Firm , and has practised…

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…

ICBEST provides a worldwide forum for the exchange of information and discussion of recent developments in Building Envelope Engineering.  It aims to bridge the gap between researchers, engineers, designers and manufacturers to enhance the exchange of ideas between them.  An equally important objective is the application of new findings to the development of design, manufacturing and construction methods and the codification of information for practicing engineers and architects. BCBEC in cooperation with NRC-IRC is hosting the ICBEST 2010 conference.

This presentation sheds some light on two technologies pertaining to optimizing performance in commercial fenestration - structural thermal barriers for aluminum window framing and warm-edge spacer technology for insulating glass. The presentation includes the following discussion: 1. Discuss the various comfort and performance-related topics in fenestration systems including, overall U-factor, condensation resistance factor (CRF), sound transmission OITC (Outdoor Indoor Transmission Class) 2. Compare two methods for optimizing the performance of aluminum fenestration components through the application of thermal barriers in…
