W130 Methods of Façade Retrofit for Occupied Commercial Buildings
(Rob Wood, C3 Polymeric)
The majority of commercial buildings in Canada are at an age where renewal of the façade must be considered. This presentation discusses common failures in curtain walls and their root causes, helping professionals understand how to make the best retrofit decisions. A variety of case studies from significant retrofits, including an in-depth look at 400 University and a basic one at Toronto City Hall, will be used to demonstrate challenges, best methods, and other factors in façade retrofit.W131 Building Envelope Assessment: Dealing with the Cause, Not the Symptom
(Michael Doiron, Enerplan Building Consultants)
For older condominiums and apartments, the building envelope, which includes exterior walls, windows, doors, and roofs, is the largest and most expensive part of the building—however, it rarely receives the attention it requires. This presentation will identify and assess typical issues with building envelopes in older multi-residential buildings, and explore how design and construction professionals can deal with them.

10:30 a.m.–12:00 p.m.
W132 Air Barrier vs. Vapour Barrier: Understanding Function for the Performance of Your Building
(Steve Tratt, Canam Building Envelope Specialists)
Air leakage through the building envelope can lead to condensation, moisture damage, rain penetration, and poor indoor temperature and humidity control. According to tests carried out by the National Research Council of Canada (NRC), air leakage accounts for 30 to 50 per cent of heat loss. Understanding the diverse roles of air and vapour barriers is key to preventing this. This seminar discusses the effect of air leakage on the above problems, along with corrective methods and calculation methodology, with examples of typical design and engineering oversights and case studies on the insulation of arenas with brine headers.

W133 Masonry Repairs and Retrofits for Occupant Comfort, Energy Efficiency, and Building Life Cycle

1:00 p.m.–2:15 p.m.
W134
EIFS Cladding Durability and Energy Code Changes: Climate Change, We Have You Covered
(John Edgar, John R. S Edgar Consulting)
Energy conservation requirements are being redefined to accommodate climate change. To meet the terms of the Paris Accord, stretch-building codes will position the building envelope as the principal element in energy conservation, while trade-offs for mechanical systems will be reduced or eliminated. Exterior insulation finish systems (EIFS), now incorporated into the National Building Code of Canada (NBC) as the most rigorously evaluated claddings available, meet both the CCMC Technical Guide and ULC S716. This presentation covers codes, standards, technical detailing, and
ensuring durability.

W135 An Insightful Update on Mould, Moisture, and Envelope Failures
(Bruce Stewart and Paul Johannesson, Pinchin)
Property managers are responsible for preventing, or at least mitigating, mould growth in their buildings. Failures of the building envelope are frequently the cause of mould growth, which can occur whenever conditions of excess moisture are present. This session offers advice on responding to water damage or mould growth, and on diagnosing and correcting common building envelope failures.

W136 Air and Water Barriers: How to Specify, Detail, Construct, and Inspect for Success
(Peter Saunders, Marc Tropper, and Christopher Armour Henry Company Canada)
Successful installation of an air and water barrier starts with a solid understanding of its proper specification, detailing, inspection, and installation. This talk provides such an understanding through discussion of three categories: physical properties (beyond air leakage) and new test methods/standards; how to specify and incorporate these properties and methods; and hands-on application (how to prepare substrate and install the membrane correctly, what to look for during an inspection, and remedies for common mistakes).

W152 Case Study on Concrete Restoration: What’s New and Innovative
(Daniel Rosa [Vector Corrosion Technologies], Jeremy Horst [Read Jones Christoffersen], Walid Habis [Momentus Engineering Management], and Greg Dolenc [Sika Canada])

Canadian roofing systems are increasingly providing environmental benefits such as energy saving and energy harvesting. In order to improve roofing developments, The National Research Council of Canada (NRC) has been conducting research to increase understanding of how these systems perform. As part of this research agenda, this presentation will examine the development of a national wind uplift standard for vegetated roof assembly. It looks at how to turn roofs into energy-producers, and explores the long-term performance of advanced insulation.

T138 Façade Renewal: A Tale of Two Buildings
(Scott Armstrong and Andrea Yee, WSP Canada)
Canada’s existing building stock is aging, and building owners must weigh the costs and benefits of investing in major building renewal. Façade renewal can improve esthetics, replace deteriorated materials, reduce energy consumption, and satisfy occupant comfort demands. Building science and energy consultants can provide valuable input on this matter, preventing owners from deferring important repairs. Client objectives, esthetic enhancements, energy analysis, logistics, and technical considerations will be discussed, with two case studies for demonstration.

T152 Architectural Precast Concrete: A Stunning and Resilient Solution to Your Building Enclosure Esthetics
(Bob Fedchyshyn, Nawkaw Corporation and Brian Hall, Canadian Precast/Prestressed Concrete Institute)
As developers and owners compete to attract tenants and buyers, there is increasing demand for variety in esthetics. To add visual interest and depth to façades, many designers are using brick-faced precast concrete panels. These combine the structural advantages of architectural precast with the esthetics of clay masonry, without the time and cost of onsite bricklaying. Formliners, colours, and stains can be manufactured to create almost any design desired.

2:30 p.m.–4:00 p.m.
T136
CAN/ULC S741 and S742 – Do You Know Your Canadian Air Barrier Standards?
(Jean-François Cote, Soprema)
Two new standards for air barriers have appeared in Canada, in 2008 and 2011 respectively: CAN/ULC S741 (for air barrier materials) and also ULC S742 (for air barrier assemblies). Both were reaffirmed in 2016, but their use in Canada is still quite limited. Participants will learn the differences between CAN/ULC-S741 and ASTM E2178 and those between CAN/ULC-S742 and ASTM E2357, find out the relevance of CAN/ULC-S741 and S742 for Canadian projects, and recognize that air barrier assemblies include those on the roof—not just walls.

T137 Large Building Airtightness: Where We’re  At and Where We’re Going
