Emerging Solutions for Mass Timber in Healthcare
Resource Description Healthcare buildings are among the most complex and resource-intensive structures we design and, increasingly, they are being asked to do more. Modern hospitals not only need to support healing for patients and staff, but also to contribute to planetary health by reducing carbon emissions and addressing social and environmental determinants of wellbeing. To meet these goals, hospital design must evolve beyond the “squeezed and standardized” approach that has long defined it. Mass timber is emerging as a credible alternative to conventional systems for larger-scale, high-rise institutional buildings. Recent advancements in material science, manufacturing, engineering, and fire safety have made it possible to consider timber as a structural solution for complex facilities — including hospitals. Recognizing that innovation in healthcare design must be evidence-based, this collaborative study explores the feasibility of using mass timber for a 200+ bed acute care hospital. The multidisciplinary team — including KPMB Architects, PHSA (Provincial Health Services Authority of BC), Fast + Epp, Smith + Andersen, Resource Planning Group, CHM Fire, Hanscomb, AMB Planning, and EllisDon — developed and evaluated a detailed test design for a mass timber inpatient tower suited to the Canadian context. The study examined structure, cost, schedule, lifecycle carbon, code compliance, infection control, and biophilic design as part of a holistic approach to sustainable healthcare infrastructure. Learning Objectives Identify the key drivers that influence structural system selection in healthcare building design. Describe the opportunities, limitations, and specific considerations associated with using mass timber in hospital environments. Summarize findings from an in-progress feasibility study for a mass timber inpatient tower in a Canadian acute care setting. Evaluate the comparative schedule, cost, and lifecycle carbon outcomes identified in the study, and discuss implications for future healthcare projects.

Vertical Additions: An innovative pathway to delivering more homes
Course Overview Discover the innovative approach to housing supply undertaken by Pathway Non-Profit Community Developments Inc. of Peel. The Arbor Mill expansion sets a remarkable precedent for other non-profit affordable housing providers who want to build more housing and can do it by adding additional units on top of their existing buildings. Globally, it is estimated that approximately 20-25% of existing buildings can support a vertical addition in wood, which is a comparatively light weight building material. This novel approach removes the need to find new land to develop and has the added benefit of immediately integrating new residents into an existing supportive community. This project added 6 barrier-free, affordable apartments on top of a 35-year old, occupied residential building using prefabricated mass timber, delivering more affordable housing through the “gentle densification” of existing infrastructure. In this webinar, the project team will discuss the architectural, structural, and design challenges of the project, including blending prefabricated mass timber construction methods with an older structure built with conventional materials. Key sustainability and construction considerations will also be highlighted. Don’t miss this opportunity to gain valuable insights from one of the first project teams in North America to pursue this innovative approach to housing delivery. Learning Objectives Participants will learn how Pathway, a non-profit community developer in Peel Region, created a plan to expand its housing portfolio while addressing tenant needs and priorities. Participants will gain insights into the design and approval challenges of the project, including navigating site plan approvals, integrating mass timber, and meeting acoustic and fire safety requirements. Participants will understand the structural considerations for vertical expansions, which include performing load assessments and evaluating structural options. Participants will understand the mass timber fabricator’s process and the key considerations for successfully integrating prefabricated mass timber components into a project, including early involvement, securing production spots, and managing construction timelines.

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.

Aspen Art Museum: Creating an Innovative Wood Structure
Course Overview The Aspen Art Museum, designed by architect Shigeru Ban, includes a long-span three-dimensional wood space-frame roof. Ban’s charge was to create a wood space frame with spans of more than 50 feet and cantilevers of 14 feet, in a structural depth of 3 feet. The space frame was to have two planes of intersecting diagonal webs of curved members that undulated up and down to touch the planes of the top and bottom chords with no visible connectors. This case study presentation will describe the design and construction of the wood structure, including paths explored but not chosen for the final design. Learning Objectives Articulate the particular demands associated with creating a 3-dimensional space frame entirely in wood.
