Changing The Way We Build: The Mass Timber

Mass timber is becoming an increasingly viable alternative to traditional structural materials, such as steel and concrete. As mass timber continues to re-emerge into the mainstream, it presents our industry some unique challenges as well as a number of opportunities for development. Mark Gaglione will present a "level setting" of what mass timber actually is and then discuss how these modern materials are changing the way we design, procure, and build today.

Speaker: Mark Gaglione, EllisDon Corporation
Initially trained as an engineer, Mark spent the early part of his career in private real estate development. Now at EllisDon, Mark works in the Construction Sciences Division where he is focused on accelerating the adoption of mass timber and other emerging construction technologies. When not promoting the building of remarkable and meaningful mass timber structures, Mark enjoys exploring the great outdoors, woodworking projects, and is a serial pasta eater. Mark is a licensed professional engineer in Ontario.

9:40 - 10:10 am

Mass Timber and Moisture Protection

Ontario is going to be building quite a few mass timber buildings! Wood is a wonderful building material: it can get wet and dry more than many materials that we currently use in buildings; however, there are limits. As we build more mass timber structures, we need to consider protection from exposure to moisture before, during, and after construction. Alex Lukachko from RDH Building Science Inc. will talk about wood wetting and drying and then discuss the steps that should be taken early in the project to integrate moisture protection into the design and construction process.

Speaker: Alex Lukachko, Principal, Senior Building Science Specialist, RDH Building Science Inc.
Alex is a Senior Building Science Specialist and the Regional Manager for our Ontario offices. Alex has a background in architecture and building science and is typically involved in early project stage consulting for high-performance new construction or retrofits, using an integrated approach to the enclosure, mechanical system and energy performance design. He is a Lecturer at the John H. Daniels Faculty of Architecture, Landscape and Design at the University of Toronto and has active research interests in the development of future building enclosure systems and the design of high performance, low environmental impact buildings. In particular, he is interested in the link between architectural design and quality assurance that ensures high building performance.

Passive House CLT

Malcolm is a vigorous promoter of radical energy conservation as the most pragmatic and viable route to building sustainability, and in this capacity he has also presented at six international Passive House conferences. This presentation will examine the broader context and current viability of CLT projects in cold climates and will review the experiences gained in designing and building Quebec’s first Passive House CLT project in 2018.

Speaker: Malcolm Isaacs, Director, CanPHI
Malcolm Isaacs is an engineering graduate of the University of Ottawa with over 25 years’ experience in construction and energy conservation in Canada, as a licensed professional engineer, designer, builder, researcher, teacher and writer.

Mr. Isaacs is a Passive House pioneer in Canada; in 2005 he designed and built the first Canadian house to Passive House specifications, and in 2010 he cofounded the Canadian Passive House Institute (CanPHI), as a public education and training organization. He’s since become the most experienced and accomplished Passive House educator in Canada, having taught the demanding international Passive House Designer curriculum to hundreds of building professionals across Canada over the past 8 years. In 2017, Malcolm became the first PHI-accredited Passive House Certifier in Québec.

Mr.Isaacs is also principal of a Quebec-based construction and consulting company which now designs affordable prefabricated buildings in CLT and other natural materials, as the most responsible, sustainable and cost-effective route for achieving Passive House performance.

11:00 - 11:30 am



Connecting the Dots

In his presentation, Craig will talk about opportunities for “connecting the dots” in the mass timber industry in Canada to increase the adoption and uptake of mass timber into the construction and development industries. As part of his presentation, Craig will talk about the formation of the Mass Timber Institute and its plans to connect the needs of mass timber consumers to both the research and production sectors.

Speaker: Craig Applegath, Founding Principal, Dialog Design
Architect, urban designer, and a pioneer in the planning and design of zero-carbon buildings and campuses, climate adaptation, and regenerative cities, Craig is a principal and founding partner of DIALOG’s Toronto studio.

Trained as a biologist, and then as an architect and urban designer, Craig is passionate about finding planning and design solutions that make sense in a world challenged by climate change and environmental deterioration. Since graduating from the Graduate School of Design at Harvard University with a Master of Architecture in Urban Design, Craig has focused on leading complex, sustainable planning and design projects, and is internationally recognized for his design and advocacy of zero-carbon regenerative buildings and cities, as well as mass timber design. Craig’s area of practice at DIALOG includes the master planning and design of institutional and mixed-use projects.

Craig is a founding Board Member of Sustainable Buildings Canada, and a past President of the Ontario Association of Architects. Craig was made a Fellow of the Royal Architectural Institute of Canada for his services to the profession of architecture, and an Honourary Member of the Ontario Association of Landscape Architects for contribution to the profession of landscape architecture. Craig was appointed Acting Chairman of the Mass Timber Institute and is now working with the MTI Council to reshape the MTI into a National Organization.
