CLT classrooms: A pilot project in Washington State
Course Overview
A pilot project in Washington State tests the use of CLT to design and construct three modular classroom buildings in Western Washington. Funded by the Washington State Legislature, the project investigated the viability of CLT as a means to build quality K‐3 classrooms to accommodate increased population and new WA State education laws. By using CLT, the project team designed a building that could be deployed on almost any existing school site and be built over a summer break without impacting ongoing operations. Compared to traditional portable classrooms, the CLT classroom buildings are longer lasting, more functional, and aesthetically superior.
Learning Objectives
Building a broad‐based CLT coalition and the unified strategies for securing legislative state support and funding ($5.5 mil USD).
Architectural design and detailing strategies used to create an innovative learning environment by using CLT.
Project scheduling, costing, construction and lessons learned through building the modern classrooms at these three schools.
Utilizing a design‐build delivery method.

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.

Canadian Wood Council Welcomes Federal Investment in Forestry Innovation and Housing Solutions
August 5, 2025 – (Ottawa, ON) The Canadian Wood Council (CWC) welcomes today’s announcement by Prime Minister Mark Carney in Kelowna, unveiling a $1.2 billion investment to support Canada’s forest sector and accelerate the use of Canadian wood in domestic construction.
The measures – including $700 million in loan guarantees and $500 million to advance innovation, workforce development, and market diversification – send a strong signal of support for sustainable construction and domestic manufacturing. CWC is encouraged to see federal action aligned with the priorities it has long championed through its technical work in codes and standards and resource program delivery.
“This announcement reinforces the critical role that wood-based solutions can play in meeting Canada’s housing and climate goals,” said Rick Jeffery, President and CEO of the Canadian Wood Council. “The focus on innovation, capacity expansion, and domestic use of wood aligns well with technical insights we’ve shared over many years through our work with government, industry, and the architects, engineers, construction professionals, and developers (AECD) community.”
CWC has worked closely with federal departments and agencies, including Natural Resources Canada, on initiatives such as the Green Construction through Wood (GCWood) program, which has demonstrated the ability to de-risk early projects and help scale up Modern Methods of Construction (MMC). These approaches, such as mass timber and prefabrication, are essential to accelerating housing starts while reducing carbon emissions and supporting rural economies across Canada.
“With the Build Canada Homes plan targeting 500,000 new units annually, today’s announcement provides important tools to help scale construction innovation,” Jeffery added. “Ensuring that Canadian wood products are part of the solution is a smart investment in housing, climate action, and economic resilience.”
CWC will continue its work providing technical assistance, education, and data-driven insight to support the successful implementation of federal initiatives. The organization remains committed to working with all levels of government and industry partners to help increase the use of sustainable wood systems in construction.
What does it take to deliver better buildings? In this issue, we explore that question from a couple of different angles—primarily through a look at standout wood projects that demonstrate wood design excellence, but also through a thoughtful feature on offsite prefabrication that invites the construction industry to think critically about how we build and what it will take to build better. Through enhanced collaboration and the expanded use of technology, prefabricated construction—an approach especially well-suited to wood—is transforming the way we design and deliver buildings.
This fall, the Canadian Wood Council is proud to support Woodrise 2025, an international conference coming to Vancouver, British Columbia. As part of this event, the 5th International Congress on tall wood construction, we’ve curated nine immersive tours that offer attendees a unique opportunity to step inside some of the region’s most compelling wood projects for a firsthand look at the leadership and innovation happening here.
If you believe one of the best ways to learn about a building is to walk through it—this is your chance. The full tour lineup is available now at www.woodrise2025.com/offsite-tours. Join us to explore everything from sustainable forest management and advanced manufacturing to some of the region’s most iconic mass timber buildings – experiences that bring together the people, materials, and design approaches shaping the future of low-carbon construction in B.C. and beyond.
We hope this issue inspires you to keep exploring what’s possible with wood—whether in your own projects or out with us on tour.
Webinar: Exploring the Feasibility of Point-Supported Mass Timber for Tallwood Construction
Canadian Wood Council Applauds Nova Scotia’s Prioritization of Wood Products for Construction and Heating in Public Buildings
OTTAWA, ON, 18 July 2025 – The Canadian Wood Council (CWC) applauds the Province of Nova Scotia’s recent announcement regarding the prioritization of wood products for construction and heating in public buildings – a strategic move that supports economic growth, climate resilience, and innovation in the province’s forestry sector.
By committing to mass timber and other solid wood products for construction, alongside the use of wood pellets, biomass, and other products made from forest residuals for heat and energy, Nova Scotia is taking a leadership approach to development that aligns environmental stewardship with economic opportunity.
This initiative reinforces the principles of a circular economy built on sustainable forest management. This comprehensive approach to fibre utilization ensures the province is maximizing the value of harvested wood and reducing waste while simultaneously supporting jobs, stimulating rural economies, and strengthening local and regional supply chains across the forestry and construction sectors.
“This commitment from the province of Nova Scotia not only supports local forestry and bioeconomy innovation, but also delivers practical solutions to reduce emissions, improve energy security, and build with a lighter carbon footprint,” says Rick Jeffery, President & CEO of the Canadian Wood Council. It’s a smart and timely commitment to sustainability that will strengthen local industries while advancing practical, low-carbon building solutions.”
