Osmosis and Blistering of Liquid Applied Waterproofing Membranes – What We Have Learned in the Past Decade
Cold-applied liquid waterproofing and roofing membranes of various chemistries have become increasingly popular in past decades, particularly over concrete podium slab, roof decks, and planters in protected/inverted roofing applications. While cold-applied membranes have their benefits in waterproofing due to their ease of use and economics – they have had their share of problems. Several years ago the roofing industry began to find systemic water-filled blisters under many of these cold-applied membranes, in cases so severe that the premature replacement of these membranes has now become commonplace. Water filled blisters often become visible within the first 5 years of service and progressively get worse with expanding pressure until entire roof areas are consumed. Water leaks occur and floating pavers are a common side effect. Many years ago the cause of the blisters had the industry scratching its head and a wide range excuses from inadequate membrane thickness and pin-holes, detailing, shoddy workmanship, to outward vapor drive were supposedly to blame.
Almost a decade ago a study was initiated to find the physical building science mechanism responsible. This study encompassed field studies, building monitoring, and several iterative laboratory experiments, until eventually the water transport process of osmosis through the membrane was confirmed. This presentation covers the story of how the phenomenon of osmosis was discovered, the physical mechanism of osmotic blistering and the scenarios where it can occur, and the new testing protocol developed. The test results for a wide range of new and aged membranes commonly used within the roofing and waterproofing industry will be presented along with recommendations for the material properties needed to prevent osmotic blistering from occurring.

How to Build A Glass House
This talk will be aimed at discussing some interesting challenges that we faced in projects involving glass. The focus will be on the use of glass as a structural material rather than a finishing/ building enclosure element including glass floors, beams, bearing walls, point supports, shear walls, and roofs.
BVDA Façade Engineering Ltd.
Mark Brook, B. Eng., M. Eng., P. Eng. is a principal of BVDA Façade Engineering Ltd. Mark is an industry leader with respect to cladding and glazing design. He has been involved as a façade consultant on many of the country’s tallest, largest and most complex glazed building projects.
Building on a formal education in structural engineering (B. Eng, M. Eng.) Mark began his career in structural engineering which eventually lead to a chief engineer’s role at one of Canada’s large glazing contractors. After exposure to the contracting side Mark moved to Morrison Hershfield Ltd. leaving the firm as a principal in the building envelope division to found Brook Van Dalen & Associates in 1993. Starting with Library Square in Vancouver and extending to major projects across the country the firm, now BVDA Façade Engineering, has a national presence with respect to façade design, testing and construction. Mark is active in the industry involved in standard development and industry committees primarily related to glass and its use in buildings.
Contrary to some claims to the contrary ‘glass breaks’. It is a perfectly elastic brittle material that is subject to imperfections and will fail under the right (or wrong) conditions. When glass breaks and there is no one present to witness it the term ‘spontaneous breakage’ is held up as the cause of failure. However all glass breaks for a reason and given the proper investigation the cause of failure can usually be isolated.
This presentation will focus on two particular modes of glass failure highlighted by recent events. News outlets would have led you to believe the sky was falling in Toronto and for that matter in Seattle, Austin and Chicago in the summer of 2011. Spontaneous breakage of balcony glass received much attention and resulted in changes to City practices and special amendments to building codes and a new draft national standard.
On a quieter note reports of spontaneous breakage of spandrel glass were on the rise much to the consternation of new building owners. The standard specification of heat strengthened spandrel glass was apparently now not sufficient to meet the installed conditions.
Reviewing the investigations of the above breakage events provides insight into why glass breaks and how to move forward to reduce future events.

BEC Talks – Roof Insulation:
Design Considerations – Roof Insulations
The majority of roof designs will incorporate some form of insulation to provide a thermal separation from interior to exterior; however, there are a lot of options with respect to insulations especially within conventionally insulated roofs. This presentation will focus on what the numbers on the tech data sheet mean from a design perspective and where to look further for additional information to ensure that all aspects of the design are considered so that failures do not occur from a simple misunderstanding.

Committed to contemporary, innovative and sustainable architecture, the team focuses on creating healthy and cost-effective architecture, including the Passive House concept, with the ultimate goal of positively impacting the lives of each person within the community.
The Envelope and Passive House: An Architect’s Visual Design Process
Ideas, Problems, and Collective Solutions… These are the basis of each sustainable building project.
Built forms are being designed with tighter envelopes to address the growing interest in energy savings within single-family and multi-family homes, such as the Passive House standard in Canada. While many factors come into play when designing a sustainable building, all are not evident to all parties during the design process. Therefore this presentation will take a team approach to identify some aspects of the architectural design process as it relates to various building envelope challenges associated with sustainable architecture, and it will pose the question: How can you contribute to the creative commons for sustainable building?
