词条 | Biophilic design |
释义 |
Biophilic design is a concept used within the building industry to increase occupant connectivity to the natural environment through the use of direct nature, indirect nature, and space and place conditions. Used at both the building and city-scale, it is argued that this idea has health, environmental, and economic benefits for building occupants and urban environments, with little drawbacks. Although its name was coined in recent history, indicators of biophilic design have been seen in architecture from as far back as the Hanging Gardens of Babylon. Biophilia hypothesis{{Main|Biophilia hypothesis}}Defined by Edward O. Wilson as the “the innate tendency to focus on life and lifelike processes”,[1] the biophilia hypothesis is the idea that humans have an inherited need to connect to nature and other biotic forms due to our evolutionary dependence on it for survival and personal fulfillment.[2] This idea is relevant in daily life – humans travel and spend money to sightsee in national parks and nature preserves, relax on beaches, hike mountains, and explore jungles. Further, many sports revolve around nature such as skiing, mountain biking, and surfing. From a home perspective, people are more likely to spend more on houses that have views of nature; buyers are willing to spend 7% more on homes with excellent landscaping, 58% more on properties that look at water, and 127% more on those that are waterfront.[3] Humans also value companionship with animals. In America 60.2 million people own dogs and 47.1 million own cats.[4] BiophobiaWhile biophilia refers to the inherent need to experience and love nature, biophobia is a human's inherited fear of nature and animals. In the case of modern life, humans urge to separate ourselves from nature and move towards technology; a cultural drive where people tend to associate with human artifacts, interests, and managed activities.[5] Some anxieties of the natural environment are inherited from threats seen in anthropocentric evolution: this includes fear of snakes, spiders, and blood.[1] In relation to buildings, biophobia can be induced through the use of bright colors, heights, enclosed spaces, darkness, and large open spaces are major contributors to occupant discomfort.[6] DimensionsConsidered as one of the pioneers of biophilic design, Stephen Kellert has created a framework where nature in the built environment is used in a way that satisfies human needs – his principles are meant to celebrate and show respect for nature, and provide an enriching urban environment that is multisensory. The dimensions and attributes that define Kellert's biophilic framework are below. Direct experience of natureDirect experience refers to tangible contact with natural features:
Indirect experience of natureIndirect experience refers to contact with images and or representations of nature:
Experience of space and placeThe experience of space and place uses spatial relationships to enhance well-being:
Each of these experiences are meant to be considered individually when using biophilia in projects, as there is no one right answer for one building type. Each building's architect(s) and project owner(s) must collaborate to include the biophilic principles they believe fit within their scope and most effectively reach their occupants. City-scaleTimothy Beatley believes the key objective of biophilic cities is to create an environment where the residents want to actively participate in, preserve, and connect with the natural landscape that surrounds them. He established ways to achieve this through a framework of infrastructure, governance, knowledge, and behavior; these dimensions can also be indicators of existing biophilic attributes that already exist in current cities.
BenefitsBiophilic design is argued to have a wealth of benefits for building occupants and urban environments. For cities, many believe the biggest proponent of the concept is its ability to make the city more resilient to any environmental stressor it may face. Health benefitsCatherine Ryan, et al. found that elements such as nature sounds, improved mental health 37% faster than traditional urban noise after stressor exposure; the same study found that when surgery patients were exposed to aromatherapy, 45% used less morphine and 56% used fewer painkillers overall.[11] Another study by Kaitlyn Gillis and Birgitta Gatersleben found that the inclusion of plants in interior environments reduce stress and increase pain tolerance; the use of water elements and incorporating views of nature are also mentally restorative for occupants.[9] When researching the effects of biophilia on hospital patients, Peter Newman and Jana Soderlund found that by increasing vista quality in hospital rooms depression and pain in patients is reduced, which in turn shortened hospital stays from 3.67 days to 2.6 days.[12] In biophilic cities, Andrew Dannenberg, et al. indicated that there are higher levels of social connectivity and better capability to handle life crises; this has resulted in lower crime rate levels of violence and aggression.[13] The same study found that implementing outdoor facilities such as impromptu gymnasiums like the “Green Gym” in the United Kingdom, allow people to help clear overgrown vegetation, build walking paths, plant foliage, and more readily exercise (walking, running, climbing, etc.); this has been proven to build social capital, increase physical activity, better mental health and quality of life. Further, Dannenberg, et al. also found that children growing up in green neighborhoods are seen to have lower levels of asthma; decreased mortality rates and health disparities between the wealthy and poor were also observed in greener neighborhoods. Environmental benefitsSome argue that by adding physical natural elements, such as plants, trees, rain gardens, and green roofs, to the built environment, buildings and cities can manage stormwater runoff better as there are less imperviable surfaces and better infiltration. To maintain these natural systems in a cost-effective way, excess greywater can be reused to water the plants and greenery; vegetative walls and roofs also decrease polluted water as the plants act as biofilters.[12] Adding greenery also reduces carbon emissions, the heat island effect, and increases biodiversity. Carbon is reduced through carbon sequestration in the plant's roots during photosynthesis. Green and high albedo rooftops and facades, and shading of streets and structures using vegetation can reduce the amount of heat absorption normally found in asphalt or dark surfaces – this can reduce heating and cooling needs by 25% and reduce temperature fluctuations by 50%.[12] Further, adding green facades can increase the biodiversity of an area if native species are planted - the Khoo Teck Puat Hospital in Singapore has seen a resurgence of 103 species of butterflies onsite, thanks to their use of vegetation throughout the exterior of the building.[12] Economic benefitsBiophilia may have slightly higher costs due to the addition of natural elements that require maintenance, higher priced organic items, etc., however, the perceived health and environmental benefits are believed to negate this. Peter Newman found that by adding biophilic design and landscapes, cities like New York City can see savings nearing $470 million due to increased worker productivity and $1.7 billion from reduced crime expenses.[12][14] They also found that storefronts on heavily vegetated streets increased foot traffic and attracted consumers that were likely to spend 25% more; the same study showed that increasing daylighting through skylights in a store increase sales by 40% +/- 7%.[12] Properties with biophilic design also benefit from higher selling prices, with many selling at 16% more than conventional buildings. Sustainability and resilienceUnder the Biophilic Urbanism section, one of the ways a city can increase resilience is by pursuing the biophysical pathway – by safeguarding and promoting the inclusion of natural systems, the natural protective barrier of the city is increased.[15] For example, New Orleans is a city that has built over its natural wet plains and has exposed themselves to flooding. It is estimated that if they kept the bayous intact, the city could save $23 billion yearly in storm protection. In the Adaptive Capacity section, Beatley states that the commitment to place and home pathway creates stimulating and interesting nature environments for residents – this will create stronger bonds to home, which will increase the likelihood that citizens will take care of where they live. He goes further in saying that in times of shock or stress, these people are more likely to rebuild and or support the community instead of fleeing. This may also increase governmental action to protect the city from future disasters. By achieving Biophilic Urbanism and Adaptive Capacity, Beatley believes that one of the biggest resilient outcomes of this framework will be increased adaptability of the residents. Because the steps leading to resilience encourage people to be outside walking and participating in activities, the citizens become healthier and more physically fit; it has been found that those who take walks in nature experience decreased depression, anger, and increased vigor, versus those who walk in interior environments. Use in building standardsGiven the increased information supporting the benefits of biophilic design, organizations are beginning to incorporate the concept into their standards and rating systems to encourage building professionals to use biophilia in their projects. As of now, the most prominent supporters of biophilic design are the WELL Building Standard and the Living Building Challenge. WELL Building StandardThe International WELL Building Institute uses biophilic design in their WELL Standard as a qualitative and quantitive metric. The qualitative metric must incorporate nature (environmental elements, natural lighting, and spatial qualities), natural patterns, and nature interaction within and outside the building; these efforts must be documented through professional narrative to be considered for certification.[16] For the quantitative portion, projects must have outdoor biophilia (25% of the project must have accessible landscaped grounds and or rooftop gardens and 70% of that 25% must have plantings), indoor biophilia (plant beds and pots must cover 1% of the floor area and plant walls must cover 2% of the floor area), and water features (projects over 100,000sqft must have a water feature that is either 1.8m in height or 4 m2 in floor area).[17] Verification is enforced through assurance letters by the architects and owners, and by on-site spot checks.[17] Generally, both metric types can be applied to every building type the WELL Standard addresses, with two exceptions: core and shell construction does not need to include quantitative interior biophilia and existing interiors do not need to include qualitative nature interaction. Living Building Challenge{{Main|Living Building Challenge}}The International Living Future Institute is the creator of the living building challenge – a rigorous building standard that aims to maximize building performance. This standard classifies the use of a biophilic environment as an imperative element in their health and happiness section. The living building challenge requires that a framework be created that shows the following: how the project will incorporate nature through environmental features, light and space, natural shapes and forms, natural patterns, and place-based relationships.[18] The challenge also requires that the occupants be able to connect to nature directly through interaction within the interior and exterior of the building.[18] These are then verified through a preliminary audit procedure. CriticismsBiophilic design is considered young, as it has not been implemented in modern building projects for a long period of time. Because of this, there has been little research that explores the long-term challenges, negatives, and even benefits of biophilia in buildings and cities.[19] Other concerns are the initial and maintenance costs of projects that implement expensive biophilic design principles.[20] This could be due to the lack of research that was discussed above, as there is little information regarding payback periods for investors. Another issue could be the prices for the technology needed, however this should eventually lower as the concept becomes more commonplace. Examples of applicationHistorical building examplesChurch of Mary Magdalene{{Main|Church of Mary Magdalene}}The Church of Mary Magdalene is in Jerusalem and was consecrated in 1888. This church's architecture is biophilic in that it contains natural geometries, organized complexity, information richness, and organic forms (onion-shaped domes) and materials.[21] On the exterior, complexity and order are shown through the repetitive use of domes, their scale, and placement.[22] Inside, the church experiences symmetry and a savannah-like environment through its vaulting and domes – the columns also have leaf-like fronds, which represents images of nature.[22] Prospect is explored through raised ceilings that have balconies and increased lighting; refuge is experienced in lower areas, where there are reduced lighting and alcoves and throughout, where small windows are encased by thick walls. Fallingwater{{Main|Fallingwater}}Fallingwater, one of Frank Lloyd Wright’s most famous buildings, exemplifies many biophilic features. The home has human-nature connectivity through the integrative use of the waterfall and stream in its architecture - the sound from these water features can be heard throughout the inside of the home.[23] This allows visitors to feel like they are “participating” in nature rather than “spectating” it like they would be if the waterfall were downstream.[24] In addition, the structure is built around existing foliage and encompasses the local geology by incorporating a large rock in the center of the living room. There are also many glass walls to connect the occupants to the surrounding woods and nature that is outdoors.[23] To better the flow of the space, Wright included many transitional spaces in the home (porches and decks); he also enhanced the direct and indirect experiences of nature by using multiple fireplaces and a wealth of organic shapes, colors, and materials. His use of Kellert's biophilic design principles are prominent throughout the structure, even though this home was constructed before these ideas were developed. Modern building examplesKhoo Teck Puat Hospital{{Main|Khoo Teck Puat Hospital}}Referred to as a “garden hospital”, KTP has an abundance of native plants and water features that surround its exterior. This inclusion of vegetation has increased the biodiversity of the local ecosystem, bringing butterflies and bird species; the rooftop of the hospital is also used by local residents to grow produce.[24] Unlike many other hospitals, 15% of visitors come to Khoo Teck Puat for recreational reasons such as gardening or relaxing.[25] The design behind this hospital was to increase the productivity of its doctors, wellbeing of its visitors, and increase the healing time and pain resilience of its patients. To do this, the designers incorporated greenery from the hospital's courtyard to its upper floors, where patients have balconies that are covered in scented foliage.[25] The hospital is centered on the Yishun pond, and like Frank Lloyd Wright's Fallingwater, the architects made this natural feature part of the hospital by having water stream through its courtyard, creating the illusion that the water was “drawn” from the pond.[25] The hospital also utilizes natural ventilation as much as possible in common areas and corridors by orienting them in the direction the north and southeast prevailing winds; this has reduced energy consumption by 60% and increased airflow by 20-30%.[25] This creates thermally adequate environments for patients and medical staff alike. Using Kellert strategies above, it is apparent that most of the strategies used for Khoo Teck Puat are direct nature experiences. The hospital also uses transitional spaces to make occupants more connected to the outdoors and has organized complexity throughout its overall architectural design. KTP has created a sense of place for occupants and neighbors, as it acts as a communal place for both those who work there and live nearby. Sandy Hook Elementary School{{See also|Newton Public Schools}}After the disaster that struck Sandy Hook Elementary in 2012, a new school was built to help heal the community and provide a new sense of security for those occupying the space. Major biophilic design parameters that Svigals + Partners included in this project are animal feeders, wetlands, courtyards, natural shapes and patterns, natural materials, transitional spaces, images of nature, natural colors, and use of natural light.[24] The school has incorporated a victory garden that is meant to act as a way of healing for children after the tragedy. The architects wanted the children to feel as if they are learning in the trees so they set the school back at the edge of the woods and surrounded the space with large windows; there are also metaphoric metal trees in the lobby that have reflective metal leaves that refract light onto colored glass.[26] Using Kellert's biophilic framework, it is prevalent that the school utilizes many different nature experiences. The use of wood planks and stone on the outside of the building help enforce indirect experiences of nature because these are natural materials. Further, the interior environment of the school experiences information richness through the architects’ use of light reflection and color. Naturalistic shapes are brought into the interior environment through the metal trees and leaves. For experiences of space and place, Svigals + Partners bring nature into the classroom and school through the placement of windows that act as transitional spaces. The school also has a variety of breezeways, bridges, and pathways for students as they move from one space to another. Direct experiences of nature are enjoyed through water features, large rain gardens, and courtyards found on the property. The animal feeders also act as a way to bring fauna into the area. City-scale examplesSingapore, SingaporeNicknamed a “city in a garden”, Singapore has dedicated many resources to make a system of nature preserves, parks and connectors (ex. Southern Ridges), and tree-lined streets that promote the return of wildlife and reduce the heat island effect that is often seen in dense city centers; local governments agree with Kellert and Beatley that daily doses of nature enhance the wellbeing of its citizens.[27][28] To manage stormwater, Singaporean governments have implemented the Bishan-Ang Mo Kio Park Project, where the old concrete water drains were excavated for reconstruction of the Kallang River; this allowed residents in the area to enjoy the physiological and physical health benefits of having a green space with water.[28] The reimagining of the park has increased the biodiversity of the local ecosystem, with dragonflies, butterflies, hornbills and smooth-coated otters returning to the Singaporean region - the river also acts as a natural stormwater management system by increasing infiltration and movement of excess water. To increase the immediate presence of nature in the city, Singapore provides subsidies (up to half the installation cost) for those who include vegetative walls, green roofs, sky parks, etc. in their building designs.[28] The city-state also has an impressive number of biophilic buildings and structures. For example, their Gardens by the Bay Project has an installation called the “Supertree Grove”. This urban nature installation has over 160,000 plants that stem from 200 different species installed in the 16 supertrees; many of these urban ‘’trees’’ have sky walkways, observatories, and or solar panels.[28] Lastly, Singapore has implemented efforts to increase community engagement through the creation of over 1,000 community gardens for resident use.[28] Oslo, NorwayOslo is sandwiched between the Oslo Fjord and wooded areas. Woods serve as an important feature to this municipality. More than two-thirds of the city is protected forests; in recent surveys over 81% of Oslo residents said they have gone to this forests at least once in the last year.[28] These forests are protected, as Oslo adheres to ISO14001 for its forest management – the trees are controlled under “living forest” standards, which means that limited harvesting is acceptable.[28] In addition to its extensive forest system, the city compounds its exposure to nature by bringing the natural environment into the urban setting. Being an already compact city (after all two-thirds is forest) the city allocates around 20% of its urban land to green spaces; the local government is in the process of creating a network of paths to connect these green areas so that citizens can walk and ride their bikes undisturbed.[28] In addition to the expanding park accessibility, the city has also restored the city's river the Akerselva, which runs through Olso's center. Because the water feature is near sets of dense housing, the city made the river more appealing and accessible to residents by adding waterfalls and nature trails; altogether the city has 365 kilometers worth of nature trails.[28]To connect the city with its fjords, Oslo's government has started the process of putting its roadways underground in tunnels. This, combined with the construction of aesthetically creative architecture (Barcode Project) on the waterfront and promenade foot trails, is transforming this area into a place where residents can experience enjoyment from the unobstructed views of the fjord.[29] Lastly, Oslo has a ‘’Noise Action Plan’’ to help alleviate urban noise levels – some of these areas (mostly recreational) have noise levels as low as 50 dB.[28] See also
