As practitioners of biophilic design, we are ever thirsty for design precedents. We are perpetually in search of tried and true evidence – the kind that corroborates myriad anecdotes and supports the relationships between nature, design, and our health and wellbeing – all to get buy-in from clients and collaborators. The challenge of this endeavor is that the evolution of design thinking moves faster than the process of scientific reporting.
In fact, it takes an average of 17 years for research evidence to become practice (Morris et al, 2011; Green et al, 2009). While this summation oversimplifies the complexities of translational medical research, policy, and adoption, it highlights the challenge design practitioners face in identifying precedents that represent a response to today’s trending awareness of the correlations between public health issues in the built environment and connectedness to nature (e.g., Mayer & Franz, 2004). Health data privacy, perceptions of competitive advantage, risk of exposing intellectual property, slow uptake of post-occupancy evaluation practices, and incomplete feedback loops collectively contribute to the dearth of documented biophilic design precedents. Consequently, we are limited to the judgement and drive of a self-selected few to make a compelling story, one that often lacks the financial or health data to capture the attention of owners and investors and ignite broad adoption.
To effectively respond to public health and wellness issues using biophilic design concepts and interventions, processes for developing and sharing topical evidence and ideas are desperately needed. We are otherwise confronted with the potentially ironic greenwashing of our ‘intuitive’ nature connection through overuse of potted plants and pretty pictures – already a recurring concern among industry thought leaders and practitioners alike.
As part of the ongoing discussion to effectuate progress and broad adoption of informed biophilic design practices, I’d like to share three perspectives that define or guide our way of thinking about, qualifying, and building healthy spaces
1. Bridging the Gap Between Science and Practice
Diffusion theorist, epidemiologist, and biostatistician Dr. Lawrence W. Green and colleagues stress that to bridge the gap between science and practice, we need to be able to approach the challenge from two complementary directions, both evidence-based practices and practice-based evidence, to contribute to what they describe as “better-informed, more relevant and actionable practices and policies” (Green et al, 2009).
Evidence-based practices (EBP) are valued for their ability to provide an explicit rationale to support design decisions, including a line of accountability and parameters for scaling-up clinically relevant research. With EBP, onus is on researchers to translate this evidence for practitioner implementation. But biophilic design in practice is inherently multidisciplinary, reaching well beyond clinical applications. Performance verification for biophilic design interventions is also far from standard protocol, making it challenging to rely on evidence-based practices alone as a strategy for broad adoption.
Despite the 17-year evidence-to-practice timeline, inadequate resources, and paucity of valid empirical evidence, EBPs have become a foundational strategy for establishing justified precedents for biophilic design, particularly in the healthcare sector and, increasingly so, in commercial workplace real estate. How this translates to other sectors is thus far riddled with assumptions – knowledge gaps that evidence-based research is unable to appease fast enough.
There are between 75 and 100 outdoor “park prescription” programs nationwide (Seltenrich, 2015) administered by a range of organizations, including Massachusetts General Hospital, Appalachian Mountain Club, San Francisco’s Golden Gate National Parks Conservancy, and the US National Parks Service, each of which is aimed at improving the health of children. The mere existence of these programs is testament to what research evidence has done thus far to educate us on the value of nature in supporting a healthy society. Government supported projects such as the Shinrin-yoku (forest bathing) program in Japan aimed at stress management, and the Green Road Project in Maryland (administered by the Institute for Integrative Health and the US Department of Defense) for military veterans coping with PTSD, also acknowledge the benefits of nature-immersion while simultaneously facilitating more research. Contextually, however, these are all outdoor programs that do not easily translate to solutions for the built environment..
2. Proving the Intuitively Obvious
Securing program funds – to validate assumptions and document the positive health impacts of nature on building occupants – is a continuous challenge. Sustainability and biophilia thought leader Bill Browning refers to this endeavor as “proving the intuitively obvious”. Herein lies a most valid point – why spend money on proving what we already know to be true? The simple answer is that as an industry we are not following our intuition.
In response to this conundrum, we’re seeing an increased leveraging of diversified, small-scale research tactics and affordable technologies to help build a body of practice-based evidence (PBE) for biophilic design in the built environment. Methods for corroborating data from indoor and outdoor experiences are rich in opportunity:
- Wrist bands, headsets, and chest straps for monitoring human health responses
- Smartphone apps, sleep monitors, gaze attention devices, urban intelligence platforms, and observation for monitoring user behavior trends
- Air quality monitors and light meters for tracking and measuring ambient environmental attributes
- Virtual reality, stress mapping, and geo-mapping to conceptualize correlations between physical space, human behavior, and health responses
Highly replicable strategies for developing practice-based evidence present an opportunity to compliment EBPs, both by filling knowledge gaps and in assisting with contextualization of evidence. Post Occupancy Evaluation (POE) is one of the more practical, adaptable, and accessible tools we have at our disposal. Since POEs are typically focused on application (Zimring & Reizenstein, 1980), they are a form of practice-based evidence, one that has the potential to be standardized but is severely underutilized in the design world. Other examples of PBE includes correlating physical measurements with complaint logs and health data, in-field experimentation, biophilic design reviews, and the exploration of metrics or parameters that support biophilic design, such as the WELL Building Standard® and the Living Building Challenge.
With the rise in wearable tech and non-invasive health monitoring devices, basic metrics for heart rate, brain waves, and salivary cortisol can be administered and tracked by the citizen scientist. While notably less scientifically rigorous than traditional research methods, the primary benefits to PBE are the expediency of data collection, reporting, and action; potential for widespread replicability with consistent metrics; ownership by citizens of their own lifestyle and design choices; and the industry-relevant nature of the research effort that helps enable immediate action.
These tools, in combination, are being used to help understand design performance challenges and opportunities while focusing on targeted health issues like stress management, restoration, and perceptions of privacy and comfort, that can be improved with greater connectedness to nature.
3. Communication and the Emotional Connection
Diffusion theory – how, why, and at what rate new ideas and technologies spread among different groups – suggests that the adoption of biophilic design may differ depending on how we communicate, the channels we use, and to which audiences. Presumably, creating a demand for biophilic built environments and acting on a willingness to share lessons learned are also determinants of how long it might take to establish a critical mass of advocates and practitioners.
Thus far, as an industry we have largely relied on science and images to communicate the benefits of the biophilic experience. The ability to capture one’s emotional connection to a place through language or imagery tends to be a skill unique to the seasoned poet or photographer. Communicating the multisensory experience, however, is necessary to gain a holistic appreciation of why a place is valued – experientially, psycho-physiologically, and socioeconomically. Escorting someone through a biophilic space can be an effective way of communicating what images and words cannot – that subtle, or sometimes blatant, qualities of nature have distinct influence over how we perceive, process, and respond to our experience of space and place. These physical or temporal experiences that allow us to better comprehend relationships with nature, help distinguish justified belief from opinion, even without scientific evidence to back it up. Thus, the intrinsic value of the emotional connection is emerging within the biophilic design movement as a viable communication tool, both to inspire the curious and convert the wary.
Since not all people have access to amazing biophilic environments, I wonder how we effectively communicate those experiences remotely and broadly. Finding an acceptable balance between these differing types of evidence may be the key to gaining greater momentum in the quest for broad adoption of biophilic design.
In Terrapin’s years of experience, we have found that the ‘how’ and ‘what’ of biophilic design research and implementation may differ from project to project, but the overarching ‘why’ is unwavering – to improve human health and wellbeing. Regardless of whether the ‘why’ is based on scientific evidence, personal experience, observation, economics, or a combination of these things, the ability to communicate the ‘why’ may be the strongest tool in your arsenal.
We’ve also found that sharing success stories and lessons learned is paramount to advancing industry adoption of biophilic design. Here are some of ours. I hope you feel inspired to share yours.
- Industry and Observational Surveys have helped confirm assumptions around user trends, pricing, and perceived value [e.g., Hospitality survey].
- Design Guidelines and Design Reviews have been a popular and replicable tool for aligning health and design owner project requirements [e.g., Clif Bar profile].
- Post-Occupancy Evaluations have been particularly effective at telling a story while providing valuable insight for prioritizing workplace design for improved stress management [e.g., CookFox case study].
- Publications have been fundamental to creating industry-wide dialogue [see Terrapin’s Publications].
