Patrick Roppel , P.Eng. is a building science engineer and project manager with Morrison Hershfield in the Vancouver office. Patrick specializes in the analysis of building envelope performance through research and heat-air-moisture modeling. Thermal performance of the building envelope has not been a high priority in the past in our temperate climate; however the requirements of sustainability programs such as LEED, energy codes such as ASHRAE 90.1 and new regulations are leading architects to ask for building envelope systems that provide…

Contingency Reserve Fund Planning for Stratas is a hot topic in BC as our legislation is weak, resulting in the need for special levies to manage repairs and replacements. Reserve Fund planning is a form of Capital Planning which has been embraced by many commercial and institutional property owners for years. In Alberta , Ontario and Nova Scotia , Reserve Fund Studies are mandatory for all Strata type properties. Some feel that BC is suffering from a "Reserve Fund Crisis"…

The presentation is intended as an information primer for Designers , and Installers on the use, detailing and design considerations when using architectural metal and zinc specifically in exterior and interior applications. A number of internationally recognized signature building solutions featuring RHEINZINK lead the presentation followed by a brief history of zinc, its development and current manufacturing technology. The material standards for zinc, quality standard certifications, environment aspects and testing results of the material are explored. For roofing and cladding systems, the…

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…
