Grading On The Curve: A practical approach to evaluating bent glass insulating units
Elie Alkhoury will explain how Can-Best is testing the curved glass for the Crown Sydney Barangaroo at Top Glass 2019. It requires some scaling and new approaches that have never been tried before. Click here to watch the video.

Advances in bent glass are inspiring architects to ever-bolder heights of design, but methods for testing and certifying these complex components are still in their infancy. In this presentation, Elie Alkhoury of Can-Best describes his groundbreaking work to assess the design of an overseas landmark building with curved insulating glass units, including assessment of seal durability on full-scale mock-ups. ASTM E2188 was adopted as the basis of evaluation with some bells and whistles added.

The presentation describes the testing of full-scale two-by-four-meter IG panels in all phases of high humidity and weather cycling with dew point measurements taken periodically. In addition to the standard weather cycling parameters of ASTM E2188, wind load pressures were superimposed on the typical cycle and applied in both positive and negative directions. The challenges did not stop there; the test panel was subjected to prescribed bending prior to cycling and assessed in the bent configuration. The complicated setup to test four panels simultaneously will be described.

Speaker: Elie Alkhoury, P.Eng., M.Eng., founder, president and CEO of Can-Best
Building Green in Toronto: TGSV3-compliant glazed assemblies
It’s Canada’s largest real estate market, and it has rules all its own. Toronto codes and standards are finally acknowledging the importance of building envelope in overall energy conservation measures. Yet highly glazed buildings continue to be in demand and have to respond to the more stringent requirements. This presentation will focus on Toronto’s TGSV3 requirements, explaining what facade designers have to do to meet both mandatory and stretch targets. We’ll also look at proposed changes to the Ontario Building Code and evaluate systems, assemblies, and components for highly glazed buildings and what it takes to achieve higher performance targets.

Speaker: Hamid Vossoughi, P.Eng., is a project principal at WSP Canada.
OGMA Awards for Excellence Presentation

The Gold Standard: Contractor and glazier certification to enhance the bid process
Building designers and glazing contractors are holding opposite ends of the same problem. Designers need a reliable method to evaluate contractors to ensure their technical expertise and good business practices. Reputable contractors need a trusted way to prove their bona fides to designers, separating themselves from those who cut corners and cut and run on contracts. This presentation takes a look at one existing solution to this problem: third-party certification of contractors and glaziers through the Architectural Glass and Metal Certification Council, a not-for-profit industry organization operating throughout North America. Through voluntary compliance with its best practices, monitored by rigorous testing and reporting, the AGMCC seeks to create a standard that will lift the fog on bid processes and raise the bar of professionalism across the industry.

Through A Glass Sideways: New efforts to measure and mitigate anisotropy
Anisotropy, as opposed to isotropy, means that a material exhibits properties with different values when measured in different directions. In architectural glass, anisotropy relates to a visual effect caused by the presence of polarized light, the birefringent property of the glass and the mechanical stresses in the glass due to heat treatment. Louis Moreau believes the industry can improve on those aspects, with the long-term goal of aesthetic improvements for glass panels. This presentation will explain the fundamentals of anisotropy, when buildings are more susceptible to it, how to quantify it, and ultimately how to minimize it.

Speaker: Louis Moreau, head of technology and innovation, AGNORA
