Naturally Sustainable: Embracing the Future with Mass Timber

Within the construction industry, Mass timber is quickly gaining popularity by providing an environmentally friendly, versatile, and visually appealing alternative to conventional building materials. Its low embodied energy, durability, and ability to sequester carbon make it an increasingly popular choice for architects, builders, and developers seeking environmentally friendly solutions.  

At the heart of this transformative movement is RJC Engineers (RJC), a leader in wood design in Canada whose expertise spans the globe in delivering cutting-edge wood projects. 

In this article, we showcase: 

• The environmental and structural benefits of mass timber. 

• Applications of mass timber in various types of construction. 

• How RJC Engineers is pioneering mass timber design and construction across Canada and beyond. 

As we explore the world of mass timber, let's discover why this material is a present-day solution to building sustainably.  

Understanding Mass Timber 

Mass timber represents a group of innovative building materials revolutionizing how we think about construction. These materials, including cross-laminated timber (CLT), glued laminated timber (glulam), and others, offer a sustainable alternative to conventional concrete and steel.  

By fastening multiple layers of wood together with glue, dowels or nails to create components such as columns, beams, and panels, mass timber products can achieve strength and durability comparable to traditional materials while also being lighter and versatile. This innovative approach to construction has seen a resurgence in recent years, largely due to mass timber's environmental benefits and its capacity for creating warm, inviting spaces. 

The Sustainability Edge 

One of the most compelling reasons for the growing popularity of mass timber is its significant environmental advantage. Wood, as a natural and renewable resource, has lower embodied carbon compared to steel and concrete, meaning its production requires less energy and emits fewer greenhouse gases.  

Additionally, trees absorb carbon dioxide as they grow, making wood a carbon-sequestering material. Buildings constructed with mass timber often have a smaller carbon footprint and serve as carbon storage, contributing to the fight against climate change.  

This sustainable aspect, coupled with advancements in forest management and wood processing technologies, makes mass timber an excellent choice for eco-conscious construction projects. 

Applications of Mass Timber in Modern Construction 

The versatility of mass timber allows its use across a broad spectrum of building types, including residential, commercial, and institutional structures. Its application is not just limited to small-scale projects; recent code advancements have paved the way for taller, multi-story wood buildings.  

Specific structural applications include: 

• Cross-laminated timber (CLT) for floors, walls, and roofs. 

• Nail laminated timber (NLT) and Dowel laminated timber (DLT) for floors and roofs. 

• Glued Laminated Timber (Glulam) beams, columns and bracing for structural supports.  

• Hybrid applications that combine mass timber with steel or concrete for enhanced structural capabilities. 

Mass timber's aesthetic appeal, with its natural warmth and texture, enhances the design and feel of spaces, making it a favourite among architects and designers. Additionally, its prefabrication capabilities can lead to faster construction times, reduced labour costs, and minimal on-site waste, further emphasizing its role as a sustainable construction solution. 

RJC Engineers: At the Forefront of Wood Design 

RJC Engineers is proud to lead innovation in wood design within Canada and across the globe. With a comprehensive understanding of mass timber's potential, RJC leverages its national resources and local expertise to deliver exceptional wood projects.  

The firm's engagement in consulting on the latest building codes for wood design with provincial and federal governments emphasizes our position as a thought leader in the field.  

RJC's commitment to excellence is evident in our diverse portfolio, which includes residential, commercial, and institutional buildings, each showcasing the unique capabilities of mass timber. 

RJC's Signature Mass Timber Projects 

RJC's prowess in mass timber design is best illustrated through the following impressive projects: 

UBC Gateway, Vancouver, BC 

This mass timber hub symbolizes UBC’s commitment to Indigenous relationships, zero-carbon design and the health and well-being of their students and staff. 

Centennial College A Building, Toronto, ON 

Targeting LEED Platinum certification, this project highlights mass timber's role in sustainable, high-performance building design. 

Craigflower Hall, Victoria, BC 

Blending history with modern engineering, Craigflower Hall's mass timber design both honours its rich cultural heritage and showcases the potential for wood in contemporary spaces. 

Innovation Crossing, Calgary, AB 

A testament to Alberta's history and future in resource use, this interpretive centre features exposed mass timber and floor-to-ceiling glazing.  

Red Deer Polytechnic Student Residence, Edmonton, AB 

The wood structure of this sustainably focused student residence incorporates a mix of light frame and mass timber components fully integrated over the height of the superstructure. 

These projects, among others, demonstrate RJC's ability to push the boundaries of what is possible with mass timber, leading the way toward more sustainable, efficient, and aesthetically pleasing construction practices. 

Why We Strive to Be Leaders in Wood Design 

RJC's leadership in wood design stems from its deep involvement in the development of Canadian Codes and Standards for wood-frame construction. By participating in national code groups, RJC helps shape the future of mass timber construction, advocating for taller wood buildings and innovative uses of wood in construction.  

Our technical expertise, combined with a forward-thinking approach, enables our talented team to transform architectural visions into reality. We're on a mission to prove that mass timber can play a central role in modern, sustainable construction.
