Biophilic Design

Outside of the home, the classroom environment is where most children spend the majority of their time. K-12 education is a pivotal time in children’s development that helps them grow intellectually and socially. Since so many factors affect student achievement during this imperative period, having a holistic view of the educational experience is important.

The focus is often on teaching techniques and curriculum, but the physical building and school surroundings shouldn’t be ignored. More and more research is highlighting the impact that classroom design––specifically design materials––has on students. In this article, I’ll explore biophilic design in the educational sector and how reclaimed wood, in particular, can benefit students.

The Benefits of Biophilic Design in Education

Given the importance of a strong education system for student success and to our economic growth and ability to compete in the global economy, it is time to rethink the spaces that our children spend so much time in. In particular, we need to reimagine the classroom as a biophilic space since studies support the positive effect of biophilic design on education. Bringing nature and natural analogues like reclaimed wood into the learning environment makes the classroom more conducive to learning, which results in more productive students and teachers.

Currently, millions of students around the world are attending school in highly urban (and thus highly unnatural) environments. These conditions hinder a child’s development. That’s because biophilic tendencies have been observed in children under two years old. This observation proves the biophilia hypothesis, which states that humans have an innate desire to connect with nature. If children don’t have access to nature, their development will be stifled.

In regards to education, this is absolutely critical. Children spend so much time in classrooms, and if the classroom setting is unnatural and lacking in biophilia, student development and enjoyment will suffer. The questions this poses for designers are important. How can design impact the learning process? How can we ensure that students live up to their full potential? These ideas are crucial to the future of the educational sector.

The Power of Biophilic Design in Educational Spaces

The praises of biophilic design are now well-known in regards to the workplace, but using biophilia in the classroom yields similarly beneficial results. One study by researchers at Texas State University and Texas A&M University found that the presence of plants improves students’ learning experience, especially in spaces that lack other natural elements like exposure to sunlight or views of nature. Biophilic spaces clearly make for better learning environments.

Biophilia drastically changes how students interact with the curriculum––and one another. The more biophilic a space is, the more interaction will take place. Basically, biophilic elements (like reclaimed wood) bring natural patterns and systems into the built environment. These patterns and systems activate the brain and help humans engage better within their immediate environment.

On an intrapersonal level, this means students will be more present, enhancing their ability to learn. Mahlum Architects is one firm that has seen this happen firsthand. They’ve seen immense benefits of wood in the classroom as a design firm that’s promoted the use of wood in the educational sector. Wilkes Elementary School on Washington’s Bainbridge Island is a beautiful example of their biophilic approach to Architecture & Design. There’s wood on virtually every surface throughout the school. The result is a highly biophilic environment that brings nature indoors and creates optimal learning conditions. It’s no surprise that the school has won many design awards and is highly rated by parents.

Interpersonally, this will facilitate improved social interaction between students. Biophilic design is closely associated with higher levels of interaction, and there’s a substantial body of research that details this. Researcher Alan Ewert looked at the effects of human interaction with the outdoors and found that people who participated in outdoor programs gained “improved cooperation, the ability to work in teams, avoidance of conflict, respect for others, leadership, and the capacity to make new friends.” In a K-12 environment, these effects can benefit children when they need it most and create an ideal balance of nature and nurture.

How Reclaimed Wood Scientifically Improves Schoolwork

So how does reclaimed wood play into all of this? In short, reclaimed wood provides generous doses of biophilia, and this grants all of the benefits mentioned in this article. It’s why schools like Wilkes Elementary that implement lots of wood see such exceptional results.

Reclaimed wood just might be the most beneficial building material for educational settings. In numerous studies, wood has proven to be particularly effective at stress reduction. One such study analyzed the effect of interior wood use on students in an Austrian secondary school. Students who were placed in solid wood classrooms experienced lower heart rates and reduced levels of stress than students in classrooms without wood. Heart rate variability also increased in the wood classrooms, and high HRV is a sign of a healthy, resilient heart according to Harvard University. In that study, HRV decreased in the solid wood classrooms. The takeaway: wood is a boon to students’ heart health.

Designers are realizing that the use of natural materials is critical to creating better learning environments. One goal, as expressed by NAC Architecture, is to blur the boundaries between the built environment inside and the natural world outside. Schools with biophilic design like Chartwell School (pictured above) or Manassas Park Elementary (pictured below) accomplish this goal beautifully. The textures and patterns available to students help to connect them with nature both visually and tactilely.

Additionally, architects are finding that reclaimed wood works well outside the classroom. Libraries, study areas, dormitories, and other on-campus facilities can all reap the rewards of reclaimed wood. In these spaces, reclaimed wood installations will help students work and study more effectively, whether individually or in groups. And since wood has been shown to increase social interaction and improve collaboration, it’s an excellent material choice for any space in which students are working together.

An investment in biophilic school design has economic and social benefits. According to PRISM, biophilic design can not only increase the tax dollar value of a school but also provide social support for children: “Nature supplies social support for children as they interact with others. When children become engaged in nature, their neural mechanisms are allowed to rest and recover.” Again, stress reduction is vital here, as the adolescent brain has been demonstrated to be especially vulnerable to stress. Reducing stress when it affects children the most has developmental, social, and emotional benefits that cannot be overstated. Furthermore, these wide-ranging effects of improved childhood development should not be overlooked because these formative years influence an individual’s economic and social outcomes later in life.

Conclusion

With current studies showing that classrooms designed with biophilic elements improve test scores, support health, and increase learning rates, it is time to elicit these positive outcomes by placing more emphasis on classroom design. Architects and designers can reimagine the classroom using biophilic design as their compass. There is an incredible opportunity to have a profound impact on education and students’ daily lives. Using lots of green building materials like sustainable wood will provide students with an environment that will help them stay connected to nature throughout their development. Schools will be healthier and students will spend their days in more productive and happier spaces, sowing the seeds for future generations to reap.

Patterns are everywhere in nature. The natural patterns found in nature deeply affect and nurture us. They are imprinted in our physiological-cognitive system and when we spend time in environments devoid of natural patterns, it leads to anxiety and stress which in the short term hampers productivity but in the long term can lead to illness. Nikos Salingaros, architectural theorist and mathematician, emphasizes that there are enormous opportunities to create healing built environments by incorporating the mathematical qualities of those found in living and natural forms.

There are many kinds of natural patterns and those that have a self-similarity are called fractals. According Salingaros, “much, if not all, of natural structure is fractal”. Fractals are patterns that repeat at different scales: If you zoom in on a picture of a fractal, you will still see the same pattern repeated.

Examples of patterns found in nature.

Richard Taylor, a physicist at the University of Oregon, and fractal fanatic, explains that “Your visual system is in some way hardwired to understand fractals,” said Taylor. “The stress-reduction is triggered by a physiological resonance that occurs when the fractal structure of the eye matches that of the fractal image being viewed.” When an environment veers away from natural patterns, it leads to some discomfort, even if subconsciously.

Science has long studied the relationship between natural patterns and the human brain. As it turns out, the brain is a powerful pattern recognition machine. One study even called pattern processing “the essence of the evolved human brain,” noting that humans have recognized the central importance of SPP [superior pattern processing] for their advancement as a species.” In other words, being able to identify patterns is an inherent part of being a human. This instinct is so strong that we even tend to perceive patterns where there are none.

Thus, it probably doesn’t come as a surprise that patterns have healing effects. Namely, patterns help to reduce stress. A 2006 study found that incorporating fractals into architecture results in lowered stress levels. Other research has shown that viewing fractals can reduce stress by as much as 60 percent. Another study found that surgical patients with rooms that featured views of nature spent less time in the hospital than patients whose rooms faced a brick wall.

Patterns also have an undeniable visual appeal that’s immediately apparent to the viewer. This has a larger implication as well: that nature and its patterns are inherently beautiful. Indeed, people are drawn toward natural materials like wood in the built environment, as observed by A. Quincy Jones. The closer a constructed environment is to the natural world, the more enjoyable it will be, and patterns play a large role here.

Salingaros, of strong opinion that the way we shape our buildings will shape us, feels minimalist spaces void of nature make us uneasy. We must bring nature and its patterns into design. Designers can incorporate natural patterns into the built environment in many creative ways. People have an affinity for natural materials. Thus, to maximize the positive effect of pattern, it makes sense to use natural materials in the process. Materials can be the vehicle to provide pattern or the instrument to create them. Think wooden spiral staircase. The spiral shape is a reflection of nature and the wood, analogous of nature, provides its own natural patterns.

The patterns present in wood are especially beautiful. The size, type and arrangement of wood cells differ from one wood species to another, and this affects the appearance of the grain.Some wood species have very figured grain pattern while others are more refined, all of which can be presented differently depending on how the wood is sawn. Reclaimed wood that has been weathered or naturally distressed over time adds another level of character that can enrich the patterns found in wood.

The Aesthetic Benefits of Patterns

Natural patterns are universally beautiful. When we view the patterns found in wood ––whether it’s a complex fractal or a simple series of cracks ––we perceive beauty. The numerous wellness benefits that patterns can provide present amazing design opportunities.

Even in ancient times, humans grasped the power and attractiveness of patterns. Perhaps that’s why the ancient Pueblo people designed complex geometric structures even though they lacked a number system and alphabet. Patterns that occur in nature, like fractals and the Fibonacci sequence, are timeless and universal. In his book Patterns in Nature, author Philip Ball summed up the effect of patterns: “Natural patterns offer raw delights, but they also point to something deep.”

This focus on patterns has been instrumental to the rise of biophilic design. In the landmark report “14 Patterns of Biophilic Design,” Terrapin Bright Green put forth 14 central concepts that detailed the relationship between humans and biophilic architecture. One of those concepts is Biomorphic Forms & Patterns. A biomorphic pattern is simply a pattern found in nature or a pattern that simulates a natural pattern. As Terrapin puts it, “The objective of Biomorphic Forms & Patterns is to provide representational design elements within the built environment that allow users to make connections to nature.” One of the best (and easiest) ways to make that happen is to use natural materials, which is why reclaimed wood is so useful.

No matter the type of wood, the abundance of patterns will have a positive effect on the viewer. The patina and weathering marks present in post-consumer reclaimed wood accentuate the natural patterns and add character.

Conclusion

Patterns make up a critical part of the natural world, and as humans, we’re meant to connect with these patterns on an innate, instinctive level. Knowing how beneficial patterns are, it makes perfect sense to build them into all aspects of design. In short, including patterns into the built environment––especially in the form of natural building materials like reclaimed wood––will optimize the design for the human brain. Occupants will be happier, more productive, and enjoy the overall experience more.

This year, there is a bevy of new, interesting design trends. Almost all of these trends have three things in common: biophilia, sustainability, and authenticity. These goals are what underlie some of the most popular design trends today, from reclaimed wood to net-zero energy usage.

Architects and designers are looking for new and innovative ways to create spaces that are healthier for humans and better for the environment. They are using design to intentionally create experiences. Some trends borrow on past artisanal methods that hearken back to another time.

One captivating design trend is an increased interest in shou sugi ban, a traditional Japanese technique of preserving wood by charring it. The resulting wood is a deep obsidian that’s strikingly rich, and it’s become more common in all kinds of commercial settings. As trendy as it may be right now, shou sugi ban is much more than just a design trend. I’d like to show you how an understanding of traditional shou sugi ban is paving the way for a new era of sustainability.

How Shou Sugi Ban Wood is Made

From Architectural Digest: Shou sugi ban involved charring wood with flame and then coating the wood to preserve it

The practice of shou sugi ban dates back to the 18th century, although some more primitive examples of the technique have been used since at least 700 AD. At its core, shou sugi ban is a fire-based wood preservation method that was used for exterior siding. Traditionally, it’s only used with Japanese cedar, which reacts to the fire in a unique way to create the trademark charcoal look.

First, pieces of Japanese cedar are handpicked to ensure the resulting wood is both beautiful and high quality. Next, the wood is burned, blackening the wood itself and creating a layer of char. Traditionally, the Japanese cedar planks were bundled into triangular tubes to create a sort of chimney. The interior was lit for an intense exposure to fire and heat. After burning, the char is brushed off and the wood is oiled. The brushing method determines the final look. Today, many try to create shou sugi ban utilizing blow torches and other species of wood. If used properly, the shou sugi ban technique can preserve wood for years, which means little to no maintenance is required. If traditional methods and wood species are not utilized there can be issues with finish longevity and stability.

The process itself provides an insight into the popularity of shou sugi ban. Builders are constantly seeking out materials and methods of creating built environments that last. Having to renovate or update a space every few years is costly and consumes lots of energy. It’s much better for the environment (and design budgets) to develop spaces that are resilient. Since traditional shou sugi ban is durable and requires very little upkeep, it’s a good choice for architects and designers who prioritize lasting and durable siding materials.

That said, while shou sugi ban produces some beautifully unique and memorable woods, depending on the wood and process used, it may not be the most sustainable process. In practice, a deep burn must be achieved or the char on the wood can fall or flake off, dirtying floors or getting onto occupants’ clothing. Loss of the top charred layer not only can create a mess and diminish the look but with it go the functional benefits of shou sugi ban; the pest, fire and weatherproof properties. In an indoor environment, there are also some air quality concerns to consider. Thankfully, there is a convenient and elegant solution to these problems, allowing you to get the appealing looks of shou sugi ban with none of the disadvantages.
