International Perspectives on Sustainable Housing Development
Course Overview Around the world there is a significant and growing housing shortage that is exacerbated by rapid urbanization and population growth. This challenge demands innovative solutions that prioritize sustainability, occupant comfort, and efficient land use. This panel discussion brings together three internationally renowned architects: Francine Houben (Mecanoo, the Netherlands), Christophe Ouhayoun (KOZ Architects, France), and Geoff Denton (White Arkitekter, Sweden) to explore their approaches to sustainable housing. Each panelist will share their unique perspective on how to address housing shortages and sustainable densification, offering insights into the latest design strategies, materials, and technologies that can contribute to more resilient and equitable urban environments. Join us for a dynamic conversation that will delve into the future of housing and the role of architecture in creating livable, sustainable cities. Learning Objectives Understand how international architects approach sustainable housing development, including wood‑based construction, urban densification, and low‑carbon strategies. Compare differing regulatory, cultural, and construction‑industry conditions that influence mass timber, modularity, prefabrication, and approval processes in Sweden, France, and Canada. Identify urban‑design principles used to create healthy, community‑oriented neighborhoods. Course Video Speakers Bio Francine Houben Founding Partner, Creative Director Mecanoo, the Netherlands Francine Houben is founding partner of Mecanoo (1984) and has led the firm to success in The Netherlands and abroad, amassing a portfolio of work that is wide-ranging, inspired by global challenges and with a sustainable view on society. Mecanoo combines the disciplines of architecture, urban planning, landscape architecture and interior design to produce unorthodox design solutions born from a strong sensitivity to context and a highly interdisciplinary design process. Each of her projects illustrates the four fundamental elements of her architectural vision: People, Place, Purpose, Poetry. Francine Houben was professor of mobility aesthetics at Delft University of Technology and taught at the universities of Harvard, Yale and Mendrisio. As curator of the First International Architecture Biennale Rotterdam (2003), she brought the theme of the aesthetics of mobility to the forefront of international design consciousness.

Mass Timber Economics: Why One Line Item Doesn’t Tell the Whole Story
Course Overview Mass timber buildings are often perceived as premium projects, but assumptions based on a single cost line can be misleading. This session explores the complexities of costing mass timber construction and highlights why a holistic, team-based approach is essential from the earliest stages of design. Attendees will gain insights into common pitfalls for cost consultants and learn how early architectural decisions such as grid spacing and aesthetic goals can significantly influence both cost and structural efficiency. The speakers will emphasize the importance of clear project objectives when setting the initial budget and outline best practices for cost predictability, including robust scope management, design reviews, and obtaining competitive bids from multiple timber suppliers. The session will also examine the role of architects in informing cost decisions, strategies for improved procurement and scheduling, and how to leverage mass timber’s expedited on-site phase. Learning Objectives Understand the complexities of mass timber costing: Participants will be able to explain why relying on a single cost line item is misleading and identify key factors—such as grid spacing and aesthetic goals—that influence overall project cost and structural efficiency.

A Zero Carbon Hybrid Wood Supertall Future
Course Overview With buildings generating 40% of global carbon emissions, we need to achieve net-zero by 2050 to meet the Paris Agreement target and limit global warming to 2°C. Timber sequesters an average of 1.9 metric tons of carbon-dioxide equivalent emissions per cubic meter (Sathre & O’Connor, 2010). While a purely mass timber tall building may not be the most cost-efficient solution, a hybrid structure can maximize the overall use of wood by volume in the most cost-efficient manner. Floor systems in buildings contribute as much as 73% of the environmental impact of a high-rise building’s structure (Lankhorst et al., 2019), making them an excellent target for reducing embodied carbon. DIALOG’s patent- pending Hybrid Timber Floor System (HTFS) takes advantage of the benefits of cross-laminated timber (CLT) combined with pre-stressed concrete to achieve a 12-metre column-free span. The HTFS is proposed as part of our Hybrid Timber Tower, a 105-storey mixed-use prototype that is being evaluated and tested by DIALOG and EllisDon. The prototype structure consists of the hybrid timber floor, combined with a concrete core and an external steel frame. Fire safety is achieved in the floor panels as the exposed wood chars to form a protective layer, while the non-combustible concrete and steel band continues to support the panel. The exposed CLT panels also provide a biophilic appeal, which has shown to support cognitive function as well as physical and psychological well-being (Vidovich, 2020). DIALOG, EllisDon, FPInnovations and other partners have completed the first phase of small-scale testing on over 40 panels. We are scheduled for fire testing of the panels in Ottawa with NRCan this fall with full scale testing of the 12-meter panels starting in late 2022. Learning Objectives Describe how hybrid mass timber systems—such as the Hybrid Timber Floor System (HTFS)—reduce embodied carbon and support zero‑carbon goals in high-rise, mixed-use developments. Explain the structural, fire safety, and performance characteristics of hybrid CLT–concrete floor assemblies, including how charring, concrete bands, and steel elements contribute to long-span capability and code compliance. Evaluate the role of multidisciplinary research, prototyping, and large-scale testing in validating hybrid timber technologies for supertall applications, including their impacts on sustainability, biophilia, and cost efficiency.
