Benefits of Building Schools with Cross Laminated Timber (CLT)

Mass Timber Buildings

Is Wood the Future of New School Construction?

“Supporters hail mass timber’s potential: the ability to speed up construction timelines in an industry plagued by inefficiencies; less environmental wear and tear; an attractive visual aesthetic; and the economic contribution of skilled jobs in an emerging industry.” They’re also quick to note wood construction at this scale is not new — and that mass timber is different from the assemblages of two-by-fours and plywood that frame American homes.” –educationdive.com

By now, you might have heard us rave about the benefits of building with mass timber. Building with engineered wood products like cross-laminated wood (CLT) has soared in popularity in recent years across the country, specifically in educational settings, and it’s no wonder! Studies show CLT can improve health and well-being, and offer more design flexibility, durability, fire resistance, as well as multiple environmental benefits. Now that students are heading back to school, we thought we’d look at the advantages of building schools with cross-laminated timber (CLT).  

Simple, Quick Construction

One of the greatest advantages of cross-laminated timber (CLT) is the speed of installation. Cross-Laminated Timber panels are lightweight and arrive at site with a structural system ready to be assembled. The process is both simple and swift, allowing immediate and accurate construction, which in turn saves time and money. 

Durability

The alternating fibers in CLT make it a lightweight, yet strong and durable building material. In Japan, a seven-story CLT building’s durability in an earthquake scenario was tested through fourteen shake-tests and came out with minimal damage. Airtight construction of each panel and precision fitting leads to seismic resilience, as does its unique strength-to-weight ratio.

Fire-Resistant

Though it may sound strange to tout fire resistance as a benefit of a wooden building material, it’s one of Cross-Laminated Timber’s greatest strengths. The lamination of CLT has inherent fire resistance, and the construction of the panels and structures allows little room for fire to breathe and expand. 

Sustainability

Another advantage to building with Cross-Laminated Timber is its light carbon footprint. CLT stores more carbon than is emitted in its manufacture and transport. It continues to store carbon absorbed by the tree while growing, keeping it out of the atmosphere for the lifetime of the building. Mass timber is the only building material that can be regrown and feasible in the long-term. Precision cutting of CLT minimizes on-site waste, and its manufacturing requires less energy than producing steel or concrete. 

Acoustic Insulation

Solid wood paneling provides superior acoustic insulation, dampening both airborne and impact noises. Its lightweight nature also leads to quiet construction, making it ideal for schools and college campuses. 

Thermal Insulation

In the same way that Cross-Laminated Timber’s airtight design creates auditory insulation, it also creates thermal insulation. Tightly packed panels can trap 90% of the heat that would ordinarily escape from a home. CLT’s previously-mentioned high thermal mass ensures temperatures are kept stable and comfortable.

Pleasing Aesthetic

There’s a warm, soothing visual quality to building with wood that separates it from the lifeless concrete slabs that typically fill a city. The term “biophilia” describes the soothing effect that natural materials have on humans. Studies suggest that natural building materials like Cross-Laminated Timber can help lower stress in students and teachers and increase productivity. 

Affordable

When comparing the manufacturing costs of certain steels and concrete, as well as the money saved on shorter construction time, CLT comes out as at a competitive

Examples of Schools Using Cross-Laminated Timber (CLT) Architecture

These examples of cross-laminated timber (CLT) architecture in educational settings demonstrate why CLT is an excellent alternative for more conventional building materials like steel and concrete.

Franklin Elementary School- Franklin, West Virginia 
When Franklin, West Virginia needed a new elementary school, the small, rural community decided to try something that no other school district had undertaken in this country: build with cross laminated timber (CLT).

Andy Quattlebaum Outdoor Recreation Center – Clemson University, SC  
Brian Campa, principal at the architecture firm that designed the outdoor rec center on the campus of Clemson University, says he chose CLT as a building material for its ability to achieve long spans and lower cost of the material. Campa also lauds CLT for its significant sustainable advantages, including a lower carbon footprint. The aesthetically pleasing building intentionally connects visitors of the building with nature. “These biophilic elements are emphasized to encourage student wellness, activity, and interaction. We believe the center will become a hub for those looking for an on-campus escape,” says Campa. Read more.

Increased Exposure to Wood Can Improve Health and Well Being

Growing Evidence Suggests Biophilic Designs of Hospitals, Offices, Schools, and Other Buildings Can Regulate Stress Levels

Wood has been used as a building material for thousands of years, but we’re only beginning to truly understand its benefits. Building with wood has not merely practical and environmental benefits, but it has also been linked to better physiological and psychological wellbeing. Not only is wood aesthetically pleasing, but environments with wooden structures are also shown to cause a drop in blood pressure, lower the pulse, and have a calming effect. The result is enhanced productivity and learning, reduced stress, and improved focus. This natural phenomenon is often referred to as the Biophilia Effect and there is science behind it.

Biophilic Designs

Human beings are meant to be in nature, but modern society dictates more of our time being spent indoors rather than outdoors. To remedy this, more building designers are incorporating natural elements like exposed wood, natural light, and plants into their building structure. This concept is often referred to as biophilic design, the idea that spending time in a more natural setting can improve physical and mental health for the people who live, work, and gather in the space. The trend of biophilic design in offices and other workplaces has been growing for years.

Though research on the biophilic properties of wood is still in its early stages, there is a growing body of evidence that increased exposure to natural elements can result in an impressive list of beneficial effects, including but not limited to better learning rates, lower blood pressure, reduced stress, and faster healing. The white paper, WHY DO WE FEEL BETTER WITH WOOD?, examines the benefits of biophilic design, and the growing body of research behind it. Here are some other examples of researchers studying the physiological and psychological impact of natural elements: 

Environmental psychologist Dr. Sally Augustin and researcher Dr. David Fell found humans automatically relax when they are surrounded by views of nature, natural light, plants, and exposed wood upon their review of existing research from the U.S., Canada, Austria, and other countries. Fell (2010) studied the autonomic responses of 119 subjects in wood and non-wood offices before, during, and after a stressful mental task. In this study, sympathetic nervous system activation was lower in the wood room. Skin conductance level was lower in the wood office during the pre-and post-test periods. Further, the rate of non-specific skin conductance responses, measurable divergent stressful thoughts, in the wood office was less than half that as in the non-wood office.

Marjut Wallenius, a Docent and Doctor of Psychology at the University of Tampere concluded use of wood promotes the health and well-being of mind and body in her research, “Wood has psychological effects on people and a similar stress-reducing effect to nature,” she says. 
Source – Wood Construction Reduces Stress and Offers a Healthy Living Environment 

Wood was associated with decreased blood pressure in an Austrian study; high school students who were taught in classrooms with floors, ceilings, and walls finished in real wood had lower heart rates than students taught in classrooms with no wood elements (Kelz et al., 2011). Besides having lower heart rates, students in the wood classrooms also reported lower levels of stress than those in non-wood classrooms. 
Source- Wood in the human environment : restorative properties of wood in the built indoor environment

A Japanese study comparing physical and emotional responses to viewing wood versus steel panels found that wood had both physiological and psychological advantages over steel (Sakuragawa et al., 2005). Wood panels were associated with decreased depression or dejection, while steel increased both. Aside from mood, researchers measured a difference in blood pressure as well: wood panels were associated with decreased blood pressure or no change, while steel was associated with increased blood pressure.

Engineered wood’s surge in popularity through the years comes as no surprise to us. Willamette Valley Company is a leading supplier of wood products and custom solutions for engineered wood manufacturers and we are seeing an increase in demand for engineered wood products like never before. More and more architects and construction builders are embracing them for their economic advantages, construction quality, durability, sustainability, and aesthetics. There is an extensive range of engineered wood products we’ve written about in the past like Plywood and Cross Laminated Timber (CLT), however, we’re taking a closer look at Structural Composite Lumber (SCL) and in this post. Here are some frequently asked questions.

What is Structural Composite Lumber (SCL)?

Structural composite lumber is defined by the APA – The Engineered Wood Association as “a family of engineered wood products created by layering dried and graded wood veneers, strands or flakes with moisture-resistant adhesive into blocks of material known as billets, which are subsequently resawn into specified sizes”. 
APA- Structural Composite Lumber (SCL)

What Are Examples of Structural Composite Lumber?

Some common examples of SCL include Laminated veneer lumber (LVL), parallel strand lumber (PSL), laminated strand lumber (LSL) and oriented strand lumber (OSL). 

-Laminated Veneer Lumber (LVL) is the most widely used of the structural composite lumber products and is often used in headers and beams, hip and valley rafters, scaffold planking and the flange material for prefabricated wood I-joists. 

-Parallel Strand Lumber (PSL) is frequently used as load-bearing columns. Like LVL and glulam, PSL is used for beam and header applications where high bending strength is needed.

-Laminated Strand Lumber (LSL) is used in a variety of applications from studs to millwork components.

-Oriented Strand Lumber (OSL) is made from flaked wood strands and also used in a variety of applications from studs to millwork components.

Why Do Builders Use SCL? 

There are a range of reasons why structural composite lumber  (SCL) products are an appealing choice, here are just a few. 

-Stability & Consistency. SCL is known by builders and architects for it’s solid, uniform properties and is virtually free from warping and splitting, making it ideal for a range of industrial uses and building projects. 

-Quality & Design Flexibility. The material’s high quality and design flexibility are also appealing qualities in the building and construction industry. 

-Cost Savings. SLC is not subject to the same price volatility found in solid lumber markets. 

Environmental Sustainability. SLC is sourced from sustainably managed North American forests and produces very little waste. It can be manufactured using small, fast-grow and underutilized trees, therefore representing an efficient use of forest resources. Another interesting fact: APA-trademarked SCL products are exempt from U.S. EPA and California formaldehyde regulations due to their very low emission rates.

What is SCL Used For?

SCL’s high quality and strength makes it a practical choice for rafters, headers, beams, joists, studs and columns. Typical uses for SCL are also

Upholstered furniture frame components
Wood furniture substrate
Case goods, shelving and retail displays
Door and window components
Recreational vehicles
Truck and trailer components
Bench and seat components
Engineered flooring substrate
Concrete form wales and bracing
Domestic and export crating and packaging
Substrate for counters, tables, pool tables, and bowling alleys

Three Cross-Laminated Timber Projects We Are Happy to See

In case you haven’t noticed, we talk a lot about Cross-Laminated Timber (CLT). More and more architects and construction companies around the world are embracing CLT for its economic advantages, construction quality, durability, sustainability, and aesthetics. Some even refer to it as “Concrete of the 21st Century”.

“How can wood possibly replace steel and concrete in high-rise buildings? The answer is cross-laminated timber (CLT), a relatively new engineered wood product that is part of a broader category of products called “mass timber” that includes already popular products such as glulam beams. CLT panels can be made in dimensions up to 10 feet wide and 40 feet long and more than a foot thick.

The panels are composed of layers of individual pieces of lumber laminated together, with each layer arranged perpendicular to the next rather than longitudinally. An odd number of layers are bonded together by glue, dowels or nails. Once assembled, the panels form a box-like structure where the walls and floors provide both structural stability and lateral stiffness.” (Source: seattlebusinessmag.com).

It’s exciting to watch the innovative buildings and construction happening around the world right now using this engineered wood material. Proposals for new projects include a 500,000-sq-ft skyscraper in New Jersey, a 100-story tower in London, a 40-story building in Stockholm, and a residential complex in Vancouver. An 18-story CLT wood structure, a student residence at the University of British Columbia, is nearing completion (Source: woodworkingnetwork.com).

Here are a few projects that recently caught our eye:

McDonald’s New CLT Building in Chicago

McDonald’s new redesigned flagship store in Chicago is built predominantly with wood and cross-laminated timber (CLT) and features a number of sustainable elements. The LEED-certified building designed by Ross Barney Architects gives us a preview as to what all McDonalds stores will look like by 2020.

Watts Grove Under Construction in the U.K

Builders in the U.K. are tackling the affordable housing shortage by constructing Watts Grove, a project being built for Swan Housing, “one of the UK’s leading regeneration housing associations.” This exciting project, designed by Thistleton Waugh Artchitects features innovative design using Cross-Laminated Timber (CLT).

Is Cross-Laminated Timber a Game Changer?

Cross Laminated Timber

If you haven’t already heard of Cross-Laminated Timber (CLT) by now, you will.  More and more architects and designers are making the switch to building with Cross-Laminated Timber, some even going as far to refer to it as the “Concrete of the 21st Century”.

Nearly every day, there is news about new multi-family and commercial structures constructed using this seemingly “magical” material. It’s even being embraced by mainstream companies like McDonald’s.  In fact, demand for this material is expected to grow by as much as 15% over the next decade.

But what is it? Cross-laminated timber (CLT) is a large-scale, prefabricated, solid engineered wood panel that is made up of kiln-dried wooden boards stacked in alternating directions (where the cross of the name comes from), then stuck together with structural adhesives. While at the mill, CLT panels are cut to size, including door and window openings, with state-of-the art CNC (Computer Numerical Controlled) routers, capable of making complex cuts with high precision. Finished panels are typically 2 to 10 feet wide, with lengths up to 60 feet and thickness up to 20 inches.

Watch the video below for more details:

What are the Benefits of Cross-Laminated Timber? CLT is lightweight yet very strong, with superior acoustic, fire, seismic, and thermal performance making it ideal for long spans in walls, floors, and roofs. It’s also fast and easy to install, generating almost no waste onsite. Finished CLT panels are exceptionally stiff, strong, and stable. Other benefits include:

Simple, Quick Construction
CLT panels are lightweight and arrive on site with a structural system ready to be assembled. The process is both simple and swift, allowing for immediate and accurate construction which in turn saves time and money.

Fire-Resistant
Though it may sound strange to tout fire-resistance as a benefit of a wooden building material, it’s one of Cross-Laminated Timber’s greatest strengths. The lamination of CLT has an inherent fire-resistance to it, and the construction of the panels and structures allows little room for fire to spread. Additionally, the solid thermal mass of CLT prevents the conduction of heat from one side of the panel to the other, allowing extremely high temperatures to remain isolated to a side as the other remains at room temperature.

Sustainable
The nature of wood makes it the only building material that can be regrown and feasible in the long-term. Precision cutting of CLT minimizes on-site waste and its manufacturing requires less energy than producing steel or concrete. Cross-Laminated Timber’s light carbon footprint is one of its greatest strengths.

Acoustic Insulation
Solid wood paneling provides superior acoustic insulation, dampening both airborne and impact noises. Its lightweight nature also leads to quiet construction, making it ideal for urban development.

Thermal Insulation
In the same way that Cross-Laminated Timber’s airtight design creates auditory insulation it also creates thermal insulation. Tightly packed panels can trap 90% of the heat that would ordinarily escape from a home. CLT’s previously-mentioned high thermal mass means that temperatures are kept stable and comfortable.

Pleasing Aesthetics
There’s a warm, soothing visual quality to building with wood that separates it from the lifeless concrete slabs that typically fill a city. Cross-Laminated Timber also grants designers with the freedom to experiment with more organic and creative structures than previously allowed by old-fashioned building techniques.

When comparing the manufacturing costs of certain steels and concrete, as well as the money saved on shorter construction time, CLT comes out as at a competitive price.

“The Wood Innovations Grant Program helps create jobs in rural communities and keeps our forests healthy. By investing in strong markets for forest products, we can incentivize sustainable forest management and sustain our rural communities.” – U.S. Forest Service Chief Tom Tidwell. 

The future is certainly bright for wood products and wood energy industry! A short time ago, the U.S. Forest Service announced over $8.3 million to expand and accelerate wood products and wood energy markets. This increase will mean a total investment of over $45 million in funds from 36 business, university, non-profit, and tribal partners in 19 states. From 2013, this funding has aided in the establishing of 22 Statewide Wood Energy Teams and six Statewide Wood Utilization Teams.

Furthermore, the 2017 Wood Innovations Grant Recipients include the Arkansas Wood Utilization Council, Camptonville Forest Biomass Business Center Bioenergy Facility, Mammoth Lakes Integrated Biomass Waste Processing Center, and the Great Plains CLT market Development through Architectural Education to name a few.

On June 6, Portland officials approved a plan for the first all-wood high-rise in the United States dubbed Framework. A fitting name for what may lay the framework for other-similar all-wood high-rises to appear throughout the country. These projects are not just good for the wood industry — they are good for the country. As Gov. Kate Brown said. “Oregon’s forests are a tried and true resource that may again be the key to economic stability for rural Oregon.”

The Timber Innovation Act is another possible indicator of bright things to come. Should the bill gain Congress approval it will bring forth incentives and measures to create innovation in the timber industry and to help further development of CLT structures in the USA.

The future is no doubt a positive one for Wood Products and Wood Energy; we can’t wait to see what else is in store in the next few months.
