Ecological design or ecodesign is an approach to designing products and services that gives special consideration to the environmental impacts of a product over its entire lifecycle . Sim Van der Ryn and Stuart Cowan define it as "any form of design that minimizes environmentally destructive impacts by integrating itself with living processes." Ecological design can also be defined as the process of integrating environmental considerations into design and development with the aim of reducing environmental impacts of products through their life cycle.
159-445: The idea helps connect scattered efforts to address environmental issues in architecture , agriculture , engineering , and ecological restoration , among others. The term was first used by John Button in 1998. Ecological design was originally conceptualized as the “adding in “of environmental factor to the design process, but later turned to the details of eco-design practice, such as product system or individual product or industry as
318-424: A "process model" contrasted to a normative approach that outlines principles of design. Urban ecological design blends a multitude of frameworks and approaches to create solutions to these issues by improving Urban resilience , sustainable use and management of resources , and integrating ecological processes into the urban landscape. EcoMaterials , such as the use of local raw materials, are less costly and reduce
477-454: A building to allow for and make use of sunlight throughout the whole year. By using the sun's rays, thermal mass is stored in the building materials such as concrete and can generate enough heat for a room. Green roofs are roofs that are partially or completely covered with plants or other vegetation. Green roofs are passive systems in that they create insulation that helps regulate the building's temperature. They also retain water, providing
636-543: A common fallacy is that "green" materials are always better for the health of occupants or the environment. Many harmful substances (including formaldehyde, arsenic, and asbestos) are naturally occurring and are not without their histories of use with the best of intentions. A study of emissions from materials by the State of California has shown that there are some green materials that have substantial emissions whereas some more "traditional" materials actually were lower emitters. Thus,

A weighted index is created by giving 50% weight for environmental health objective (health) and 50% for ecosystem vitality (ecosystem); values range from 0–100. No Arab countries were in the top quartile, and 7 countries were in the lowest quartile. South Korea and Taiwan experienced similar growth in industrialization from 1965 to 1990 with few environmental controls. South Korea's Han River and Nakdong River were so polluted by unchecked dumping of industrial waste that they were close to being classified as biologically dead. Taiwan's formula for balanced growth

The term "sustainability" in relation to architecture has so far been mostly considered through the lens of building technology and its transformations. Going beyond the technical sphere of " green design ", invention and expertise, some scholars are starting to position architecture within
1749-627: A global 'race to the bottom' in which polluting industries move to areas with fewer restrictions and regulations on emissions, usually in developing countries, disproportionately exposing vulnerable and impoverished populations to environmental threats. These factors make LCA and sustainable waste sites important on a global scale. Related to ecological urbanism , Urban Ecological Design integrates aesthetic, social, and ecological concerns into an urban design framework that seeks to increase ecological functioning, sustainably generate and consume resources, and create resilient built environments and

Windows are placed to maximize the input of heat-creating light while minimizing the loss of heat through glass, a poor insulator. In the northern hemisphere this usually involves installing a large number of south-facing windows to collect direct sun and severely restricting the number of north-facing windows. Certain window types, such as double or triple glazed insulated windows with gas filled spaces and low emissivity (low-E) coatings, provide much better insulation than single-pane glass windows. Preventing excess solar gain by means of solar shading devices in

An active solar collector system can produce about 80 to 100 gallons of hot water per day. A passive system will have a lower capacity. Active solar water system's efficiency is 35-80% while a passive system is 30-50%, making active solar systems more powerful. There are also two types of circulation, direct circulation systems and indirect circulation systems. Direct circulation systems loop

Somalia is the only country without environmental law. In 2010 the Environmental Performance Index listed Algeria as the top Arab country at 42 of 163; Morocco was at 52 and Syria at 56. The Environmental Performance Index measures the ability of
2703-453: A more sustainable society. Indigenous knowledge is valuable in ecological design as well as other ecological realms such as restoration ecology. These concepts of design tie into the concept of sustainable development. The three pillars addressed in sustainable development are: ecological integrity, social equity, and economic security. Gould and Lewis argue in their book Green Gentrification that urban redevelopment and projects have neglected
2862-663: A much broader cultural framework of the human interrelationship with nature . Adopting this framework allows tracing a rich history of cultural debates about humanity's relationship to nature and the environment, from the point of view of different historical and geographical contexts. Global construction accounts for 38% of total global emissions. While sustainable architecture and construction standards have traditionally focused on reducing operational carbon emissions, there are to date few standards or systems in place to track and reduce embodied carbon. While steel and other materials are responsible for large-scale emissions, cement alone

BIM enables designers to quantify the environmental impacts of systems and materials to support the decisions needed to design sustainable buildings. A sustainable building consultant may be engaged early in the design process, to forecast the sustainability implications of building materials , orientation, glazing and other physical factors, so as to identify
3339-461: A new natural aesthetic quality is achieved. Off-grid homes only use clean electric power. They are completely separated and disconnected from the conventional electricity grid and receive their power supply by harnessing active or passive energy systems. Off-grid homes are also not served by other publicly or privately managed utilities, such as water and gas in addition to electricity. Increased applications of ecological design have gone along with

Energy efficiency over the entire life cycle of a building is the most important goal of sustainable architecture. Architects use many different passive and active techniques to reduce the energy needs of buildings and increase their ability to capture or generate their own energy. To minimize cost and complexity, sustainable architecture prioritizes passive systems to take advantage of building location with incorporated architectural elements, supplementing with renewable energy sources and then fossil fuel resources only as needed. Site analysis can be employed to optimize use of local environmental resources such as daylight and ambient wind for heating and ventilation. Energy use very often depends on whether

Select buildings were chosen in the cities of Kotka and Kouvola, their projected carbon emissions decreasing by about 590 tCO2 and 944 tCO2 respectively with a 7 - 13 year payoff period. It is, however, important to note that EAHP systems may not produce favourable results if installed in a building exhibiting incompatible exhaust output rates or electricity consumption. In this case, EAHP systems may increase energy bills without providing reasonable cuts to carbon emissions (see EAHP ). Ground-source (or geothermal) heat pumps provide an efficient alternative.

They use on-site electricity storage while on-grid sites feed in excessive electricity back to the grid. Numerous passive architectural strategies have been developed over time. Examples of such strategies include the arrangement of rooms or
12243-444: The building or underneath a parking lot. Energy Star ground-source heat pumps can be 40% to 60% more efficient than their air-source counterparts. They are also quieter and can also be applied to other functions like domestic hot water heating. In terms of initial cost, the ground-source heat pump system costs about twice as much as a standard air-source heat pump to be installed. However, the up-front costs can be more than offset by
12402-628: The coast. In 1972, in Stockholm, the United Nations Conference on the Human Environment created the UN Environment Programme . The EU's environmental policy was formally founded by a European Council declaration and the first five-year environment programme was adopted. The main idea of the declaration was that prevention is better than the cure and the polluter should pay. In the 1980s the green parties that were created
12561-482: The collector can be angled above horizontal Latitude +15°. To maximize efficiency in summer, the angle should be Latitude -15°. However, for an annual maximum production, the angle of the panel above horizontal should be equal to its latitude. The use of undersized wind turbines in energy production in sustainable structures requires the consideration of many factors. In considering costs, small wind systems are generally more expensive than larger wind turbines relative to
12720-524: The coming years. Environmental and public health is an ongoing struggle within India. The first seed of an environmental movement in India was the foundation in 1964 of Dasholi Gram Swarajya Sangh , a labour cooperative started by Chandi Prasad Bhatt . It was inaugurated by Sucheta Kriplani and founded on land donated by Shyma Devi. This initiative was eventually followed up with the Chipko movement starting in 1974. The most severe single event underpinning
12879-526: The conclusion of a lawsuit in Japan drew international attention to the effects of decades of mercury poisoning on the people of Minamata . At the same time, emerging scientific research drew new attention to existing and hypothetical threats to the environment and humanity. Among them were Paul R. Ehrlich , whose book The Population Bomb (1968) revived Malthusian concerns about the impact of exponential population growth. Biologist Barry Commoner generated
13038-436: The concomitant immense growth in coal consumption gave rise to an unprecedented level of air pollution in industrial centers; after 1900 the large volume of industrial chemical discharges added to the growing load of untreated human waste. Under increasing political pressure from the urban middle-class, the first large-scale, modern environmental laws came in the form of Britain's Alkali Acts , passed in 1863, to regulate
13197-569: The condenser and evaporator of an ASHP can switch roles and absorb heat from the cool outside air and dump it into a warm house. Air-source heat pumps are inexpensive relative to other heat pump systems. As the efficiency of air-source heat pumps decline when the outdoor temperature is very cold or very hot; therefore, they are most efficiently used in temperate climates. However, contrary to earlier expectations, they have proven to be also well suited for regions with cold outdoor temperatures, such as Scandinavia or Alaska. In Norway, Finland and Sweden,
13356-481: The consciousness of people who have destroyed forests and polluted waterways. From 1973 to the 1990s, and then in the 2000s, indigenous communities and rubber tappers also carried out blockades that protected much rainforest. It is home to several organizations that have fronted the environmental movement. The Blue Wave Foundation was created in 1989 and has partnered with advertising companies to promote national education campaigns to keep Brazil's beaches clean. Funatura
13515-457: The consumption of new goods. When new materials are employed, green designers look for materials that are rapidly replenished, such as bamboo , which can be harvested for commercial use after only six years of growth, sorghum or wheat straw, both of which are waste material that can be pressed into panels, or cork oak , in which only the outer bark is removed for use, thus preserving the tree. When possible, building materials may be gleaned from
13674-428: The costs of environmental negligence, disease, and the expansion of air and water pollution through the occurrence of several environmental disasters that occurred post-World War II. Aldo Leopold published A Sand County Almanac in 1949. He believed in a land ethic that recognized that maintaining the "beauty, integrity, and health of natural systems" as a moral and ethical imperative. Another major literary force in
13833-453: The country; the " National Trust for Places of Historic Interest or Natural Beauty " was formally inaugurated in 1894. The organisation obtained secure footing through the 1907 National Trust Bill, which gave the trust the status of a statutory corporation. and the bill was passed in August 1907. An early "Back-to-Nature" movement, which anticipated the romantic ideal of modern environmentalism,
13992-419: The creation of Earth First! , a group with an ecocentric view of the world – believing in equality between the rights of humans to flourish, the rights of all other species to flourish and the rights of life-sustaining systems to flourish. In the 1950s, 1960s, and 1970s, several events illustrated the magnitude of environmental damage caused by humans. In 1954, a hydrogen bomb test at Bikini Atoll exposed
14151-566: The decrease in energy costs. The reduction in energy costs is especially apparent in areas with typically hot summers and cold winters. Other types of heat pumps are water-source and air-earth. If the building is located near a body of water, the pond or lake could be used as a heat source or sink. Air-earth heat pumps circulate the building's air through underground ducts. With higher fan power requirements and inefficient heat transfer, Air-earth heat pumps are generally not practical for major construction. Passive daytime radiative cooling harvests
14310-589: The deleterious air pollution ( gaseous hydrochloric acid ) given off by the Leblanc process , used to produce soda ash . Early interest in the environment was a feature of the Romantic movement in the early 19th century. The poet William Wordsworth had travelled extensively in England's Lake District and wrote that it is a "sort of national property in which every man has a right and interest who has an eye to perceive and
14469-413: The displacement and exclusion of unhoused individuals, under a guise of pro- environmental ethics . One example of this type of design is hostile architecture in urban parks. Park benches designed with metal arched bars to prevent a person from laying on the bench restricts who benefits from green space and ecological design. Life Cycle Analysis (LCA) is a tool used to understand the how a product impacts
14628-777: The domestic water through the panels. They should not be used in climates with temperatures below freezing. Indirect circulation loops glycol or some other fluid through the solar panels and uses a heat exchanger to heat up the domestic water. The two most common types of collector panels are flat-plate and evacuated-tube. The two work similarly except that evacuated tubes do not convectively lose heat, which greatly improves their efficiency (5%–25% more efficient). With these higher efficiencies, Evacuated-tube solar collectors can also produce higher-temperature space heating, and even higher temperatures for absorption cooling systems. Electric-resistance water heaters that are common in homes today have an electrical demand around 4500 kW·h/year. With
14787-501: The early 2000s, activists believed that environmental policy concerns were overshadowed by energy security, globalism, and terrorism. Since that time major movements concerning issues such as climate change, fracking and other issues have arisen. The environmental movement is reaching the less developed world with different degrees of success. The Arab world , including the Middle East and North Africa , has different adaptations of
14946-677: The electric wire reel reused as a center table. There is a huge demand in Western countries to decorate homes in a "green" style. A lot of effort is placed into recycled product design and the creation of a natural look. This ideal is also a part of developing countries, although their use of recycled and natural products is often based in necessity and wanting to get maximum use out of materials. The focus on self-regulation and personal lifestyle changes (including decorating as well as clothing and other consumer choices) has shifted questions of social responsibility away from government and corporations and onto
15105-618: The electrical energy efficiencies of motors, thereby enhancing the sustainability of electrical building components. Site and building orientation have some major effects on a building's HVAC efficiency. Passive solar building design allows buildings to harness the energy of the sun efficiently without the use of any active solar mechanisms such as photovoltaic cells or solar hot water panels . Typically passive solar building designs incorporate materials with high thermal mass that retain heat effectively and strong insulation that works to prevent heat escape. Low energy designs also requires
15264-420: The electricity required of a regular domestic household dwelling. Turbines for residential scale use are usually between 7 feet (2 m) to 25 feet (8 m) in diameter and produce electricity at a rate of 900 watts to 10,000 watts at their tested wind speed. The reliability of wind turbine systems is important to the success of a wind energy project. Unanticipated breakdowns can have a significant impact on
15423-754: The energy savings of a white roof, and when applied as a multilayer surface to 10% of a building's roof, it can replace 35% of air conditioning used during the hottest hours of daytime. Daytime radiative cooling applications for indoor space cooling is growing with an estimated "market size of ~$ 27 billion in 2025." Some examples of sustainable building materials include recycled denim or blown-in fiber glass insulation, sustainably harvested wood, Trass , Linoleum , sheep wool, hempcrete , roman concrete , panels made from paper flakes, baked earth, rammed earth, clay, vermiculite, flax linen, sisal, seagrass, expanded clay grains, coconut, wood fiber plates, calcium sandstone, locally obtained stone and rock, and bamboo , which
15582-487: The environment at each stage of its life cycle, from raw input to the end of the products' life cycle. Life Cycle Cost (LCC) is an economic metric that "identifies the minimum cost for each life cycle stage which would be presented in the aspects of material, procedures, usage, end-of-life and transportation." LCA and LCC can be used to identify particular aspects of a product that is particularly environmentally damaging and reduce those impacts. For example, LCA might reveal that
15741-681: The environmental costs of shipping, fuel consumption, and CO₂ emissions generated from transportation. Certified green building materials, such as wood from sustainably managed forest plantations, with accreditations from companies such as the Forest Stewardship Council (FSC), or the Pan-European Forest Certification Council (PEFCC), can be used. Several other types of components and materials can be used in sustainable objects and buildings. Recyclable and recycled materials are commonly used in construction, but it
15900-431: The environmental movement in India is the anti-dam movement. Dam creation has been thought of as a way for India to catch up with the West by connecting to the power grid with giant dams, coal or oil-powered plants, or nuclear plants. Jhola Aandolan a mass movement is conducting as fighting against polyethylene carry bags uses and promoting cloth/jute/paper carry bags to protect the environment and nature . Activists in
16059-668: The environmental movement. Countries on the Persian Gulf have high incomes and rely heavily on the large amount of energy resources in the area. Each country in the Arab world has varying combinations of low or high amounts of natural resources and low or high amounts of labor. The League of Arab States has one specialized sub-committee, of 12 standing specialized subcommittees in the Foreign Affairs Ministerial Committees, which deals with Environmental Issues. Countries in
16218-564: The environmentally harmful Carajás iron ore mine. In 1952 the Great London Smog episode killed thousands of people and led the UK to create the first Clean Air Act in 1956. In 1957 the first major nuclear accident occurred in Windscale in northern England. The supertanker Torrey Canyon ran aground off the coast of Cornwall in 1967, causing the first major oil leak that killed marine life along
16377-403: The especially cool winds coming from nearby bodies of water . Many of these valuable strategies are employed in some way by the traditional architecture of warm regions, such as south-western mission buildings. In climates with four seasons, an integrated energy system will increase in efficiency: when the building is well insulated, when it is sited to work with the forces of nature, when heat
16536-436: The experience of China, South Korea, Japan and Taiwan reveals that the impact of environmental activism is heavily modified by domestic political context, particularly the level of integration of mass-based protests and policy advocacy NGOs. Hinted by the history of neighboring Japan and South Korea, the possible convergence of NGOs and anti-pollution protests will have significant implications for Chinese environmental politics in
16695-686: The extreme coldness of outer space as a renewable energy source to achieve daytime cooling. Being high in solar reflectance to reduce solar heat gain and strong in longwave infrared (LWIR) thermal radiation heat transfer , daytime radiative cooling surfaces can achieve sub-ambient cooling for indoor and outdoor spaces when applied to roofs, which can significantly lower energy demand and costs devoted to cooling. These cooling surfaces can be applied as sky-facing panels, similar to other renewable energy sources like solar energy panels, making them for simple integration into architectural design. A passive daytime radiative cooling roof application can double
16854-405: The fabrication stage of a product's life cycle is particularly harmful for the environment and switching to a different material can drive emissions down. However, switching material may increase environmental effects later in a products life time; LCA takes into account the whole life cycle of a product and can alert designers to the many impacts of a product, which is why LCA is important. Some of
17013-607: The factors that LCA takes into account are the costs and emissions of: End-of-life, or disposal, is an important aspect of LCA as waste management is a global issue, with trash found everywhere around the world from the ocean to within organisms. A framework was developed to assess sustainability of waste sites titled EcoSWaD, Ecological Sustainability of Waste Disposal Sites. The model focuses on five major concerns: (1) location suitability, (2) operational sustainability, (3) environmental sustainability , (4) socioeconomic sustainability, and (5) site capacity sustainability. This framework
17172-479: The forest wood that it takes during its manufacturing process. There is an underutilized potential for systematically storing carbon in the built environment. The use of natural building materials for their sustainable qualities is a practice seen in vernacular architecture . Regional architectural styles develop over generations, utilizing local materials. This practice reduces transportation and production emissions. Regenerative sources, use of waste material, and
17331-442: The global commons, managing human settlements, the use of chemicals and the management of human industrial waste, and fostering sustainable economic growth on a global scale. Though Western society has only recently espoused ecological design principles, indigenous peoples have long coexisted with the environment. Scholars have discussed the importance of acknowledging and learning from Indigenous peoples and cultures to move towards
17490-497: The importance of materials to overall building sustainability, quantifying and evaluating the sustainability of building materials has proven difficult. There is little coherence in the measurement and assessment of materials sustainability attributes, resulting in a landscape today that is littered with hundreds of competing, inconsistent and often imprecise eco-labels, standards and certifications . This discord has led both to confusion among consumers and commercial purchasers and to
17649-484: The incorporation of inconsistent sustainability criteria in larger building certification programs such as LEED . Various proposals have been made regarding rationalization of the standardization landscape for sustainable building materials. Building information modelling (BIM) is used to help enable sustainable design by allowing architects and engineers to integrate and analyze building performance.[5]. BIM services, including conceptual and topographic modelling, offer
17808-442: The individual. 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. These systems use the principle of harnessing the power generated from renewable and inexhaustible sources of energy, for example; solar, wind, thermal, biomass, geothermal, and hydropower energy. Solar power
17967-512: The infrastructure to maintain them. Urban ecological design is inherently interdisciplinary: it integrates multiple academic and professional fields including environmental studies, sociology, justice studies, urban ecology, landscape ecology, urban planning, architecture, and landscape architecture. Urban ecological design aims to solve issues related to multiple large-scale trends including the growth of urban areas, climate change , and biodiversity loss . Urban ecological design has been described as
18126-459: The interior space. Advanced louver systems are automated to maximize daylight and monitor the interior temperature by adjusting their tilt. Coniferous or evergreen plants are often planted to the north of buildings to shield against cold north winds. In colder climates, heating systems are a primary focus for sustainable architecture because they are typically one of the largest single energy drains in buildings. In warmer climates where cooling
18285-473: The maximum distance at which the facility is located from the place of consumption and the power required and permitted for each property. Water recycling systems such as rainwater tanks that harvest water for multiple purposes. Reusing grey water generated by households are a useful way of not wasting drinking water. Hydropower , also known as water power, is the use of falling or fast-running water to produce electricity or to power machines. Hydropower
18444-585: The mid-1990s to 52 people per incident in 2004. China has more relaxed environmental laws than other countries in Asia, so many polluting factories have relocated to China, causing pollution in China . Water pollution , water scarcity , soil pollution , soil degradation , and desertification are issues currently in discussion in China. The groundwater table of the North China Plain is dropping by 1.5 m (5 ft) per year. This groundwater table occurs in
18603-617: The movement called for more efficient and professional management of natural resources. They fought for reform because they believed the destruction of forests, fertile soil, minerals, wildlife, and water resources would lead to the downfall of society. The group that has been the most active in recent years is the climate movement . "The conservation of natural resources is the fundamental problem. Unless we solve that problem, it will avail us little to solve all others". Theodore Roosevelt (4 October 1907) The U.S. movement began to take off after World War II , as people began to recognize
18762-501: The movement includes private citizens, professionals, religious devotees , politicians, scientists, nonprofit organizations , and individual advocates like former Wisconsin Senator Gaylord Nelson and Rachel Carson in the 20th century. The origins of the environmental movement lay in response to increasing levels of smoke pollution in the atmosphere during the Industrial Revolution . The emergence of great factories and
18921-431: The movement is centered on ecology , health , as well as human rights . The environmental movement is an international movement, represented by a range of environmental organizations, from enterprises to grassroots and varies from country to country. Due to its large membership, varying and strong beliefs, and occasionally speculative nature, the environmental movement is not always united in its goals. At its broadest,
19080-508: The movement was the Bhopal gas leakage on 3 December 1984. 40 tons of methyl isocyanate was released, immediately killing 2,259 people and ultimately affecting 700,000 citizens. India has a national campaign against Coca-Cola and Pepsi Cola plants due to their practices of drawing groundwater and contaminating fields with sludge. The movement is characterized by local struggles against intensive aquaculture farms. The most influential part of
19239-458: The negative environmental impact of buildings through improved efficiency and moderation in the use of materials, energy, development space and the ecosystem at large. Sustainable architecture uses a conscious approach to energy and ecological conservation in the design of the built environment. The idea of sustainability , or ecological design , is to ensure that use of currently available resources does not end up having detrimental effects to
19398-639: The people learned that protesting can bring results. The polluting factories were forced to make immediate improvements to the conditions or pay compensation to victims. Some were even forced to shut down or move locations. The people were able to force the government to come out with new restrictive rules on toxins, industrial waste, and air pollution. All of these new regulations caused the migration of those polluting industries from Taiwan and South Korea to China and other countries in Southeast Asia with more relaxed environmental laws. China's environmental movement
19557-452: The phases of the life cycle are evaluated according to their environmental impact on the basis of a number of parameters, such as extent of environmental impact, potential for improvement, or potential of change. According to this ranking the recommended changes are carried out and reviewed after a certain time. As the impact of design and the design process has evolved, designers have become more aware of their responsibilities. The design of
19716-423: The possible benefits of GM crops such as water conservation through corn modified to be less "thirsty" and decreased pesticide use through insect – resistant crops. They also point out that some genetically modified livestock have accelerated growth which means there are shorter production cycles which again results in a more efficient use of feed. Besides genetically modified crops and livestock, synthetic biology
19875-598: The preceding decade, more than 1,700 land and environmental defenders were killed, about one every two days. Brazil, Colombia, Philippines, and Mexico were the deadliest countries. Violence and intimidation against environmental activists have also been reported in Central and Eastern Europe . In Romania , anti-logging activists have been killed, while in Belarus , the government arrested several environmental activists and dissolved their organizations. Belarus has also withdrawn from
20034-552: The principle of " ephemeralization ", a term he coined himself to do "more with less" and increase technological efficiency. This concept is key in ecological design that works towards sustainability. In 1986, the design theorist Clive Dilnot argued that design must once again become a means of ordering the world rather than merely of shaping products. Despite rising ecological awareness in the 20th century, unsustainable design practices continued. The 1992 conference "The Agenda 21: The Earth Summit Strategy to Save Our Planet” put forward
20193-486: The production of materials). Often sustainable architects attempt to retrofit old structures to serve new needs in order to avoid unnecessary development. Architectural salvage and reclaimed materials are used when appropriate. When older buildings are demolished, frequently any good wood is reclaimed, renewed, and sold as flooring. Any good dimension stone is similarly reclaimed. Many other parts are reused as well, such as doors, windows, mantels, and hardware, thus reducing
20352-480: The promotion of the environmental movement was Rachel Carson 's 1962 book Silent Spring about declining bird populations due to DDT , an insecticide, pollutant, and man's attempts to control nature through the use of synthetic substances. Her core message for her readers was to identify the complex and fragile ecosystem and the threats facing the population. In 1958, Carson started to work on her last book, with an idea that nature needs human protection. Her influence
20511-543: The recycled insulation effective for architectural purposes. Low-impact building materials are used wherever feasible: for example, insulation may be made from low VOC ( volatile organic compound )-emitting materials such as recycled denim or cellulose insulation , rather than the building insulation materials that may contain carcinogenic or toxic materials such as formaldehyde. To discourage insect damage, these alternate insulation materials may be treated with boric acid . Organic or milk-based paints may be used. However,
20670-483: The region of China that produces 40% of the country's grain. The Center for Legal Assistance to Pollution Victims works to confront legal issues associated with environmental justice by hearing court cases that expose the narratives of victims of environmental pollution. As China continues domestic economic reforms and integration into global markets, there emerge new linkages between China's domestic environmental degradation and global ecological crisis. Comparing
20829-406: The rise of environmental art . Recycling has been used in art since the early part of the 20th century, when cubist artist Pablo Picasso (1881–1973) and Georges Braque (1882–1963) created collages from newsprints, packaging and other found materials. Contemporary artists have also embraced sustainability, both in materials and artistic content. One modern artist who embraces the reuse of materials
20988-431: The same latitude. Typical efficiencies for commercially available PV panels range from 4% to 28%. The low efficiency of certain photovoltaic panels can significantly affect the payback period of their installation. This low efficiency does not mean that solar panels are not a viable energy alternative. In Germany for example, Solar Panels are commonly installed in residential home construction. Roofs are often angled toward
21147-450: The site itself; for example, if a new structure is being constructed in a wooded area, wood from the trees which were cut to make room for the building would be re-used as part of the building itself. For insulation in building envelopes, more experimental materials such as “waste sheep’s wool” alongside other waste fibers originating from textile and agri-industrial operations are being researched for use as well, with recent studies suggesting
21306-540: The sizing and orientation of windows in a building, and the orientation of facades and streets or the ratio between building heights and street widths for urban planning. An important and cost-effective element of an efficient heating, ventilation, and air conditioning (HVAC) system is a well-insulated building . A more efficient building requires less heat generating or dissipating power, but may require more ventilation capacity to expel polluted indoor air . Significant amounts of energy are flushed out of buildings in
21465-620: The social equity pillar, resulting in development that focuses on profit and deepens social inequality. One result of this is green or environmental gentrification . This process is often the result of good intentions to clean up an area and provide green amenities, but without setting protections in place for existing residents to ensure they are not forced out by increased property values and influxes of new wealthier residents. Unhoused persons are one particularly vulnerable affected population of environmental gentrification. Government environmental planning agendas related to green spaces may lead to
21624-421: The subject of emissions must be carefully investigated before concluding that natural materials are always the healthiest alternatives for occupants and for the Earth. Volatile organic compounds (VOC) can be found in any indoor environment coming from a variety of different sources. VOCs have a high vapor pressure and low water solubility, and are suspected of causing sick building syndrome type symptoms. This
21783-490: The summer months is important to reduce cooling needs. Deciduous trees are often planted in front of windows to block excessive sun in summer with their leaves but allow light through in winter when their leaves fall off. Louvers or light shelves are installed to allow the sunlight in during the winter (when the sun is lower in the sky) and keep it out in the summer (when the sun is high in the sky). They are slatted like shutters and reflect light and radiation to reduce glare on
21942-411: The sun to allow photovoltaic panels to collect at maximum efficiency. In the northern hemisphere, a true-south facing orientation maximizes yield for solar panels. If true-south is not possible, solar panels can produce adequate energy if aligned within 30° of south. However, at higher latitudes, winter energy yield will be significantly reduced for non-south orientation. To maximize efficiency in winter,
22101-448: The two heat pumps is that the ground-source has one of its heat exchangers placed underground—usually in a horizontal or vertical arrangement. Ground-source takes advantage of the relatively constant, mild temperatures underground, which means their efficiencies can be much greater than that of an air-source heat pump. The in-ground heat exchanger generally needs a considerable amount of area. Designers have placed them in an open area next to
22260-568: The universe. In 1972, the United Nations Conference on the Human Environment was held in Stockholm , and for the first time united the representatives of multiple governments in discussion relating to the state of the global environment. This conference led directly to the creation of government environmental agencies and the UN Environment Program . By the mid-1970s anti-nuclear activism had moved beyond local protests and politics to gain
22419-544: The unknowing frontlines of suburban sprawl . Second, they usually increase the energy consumption required for transportation and lead to unnecessary auto emissions. Ideally, most building should avoid suburban sprawl in favor of the kind of light urban development articulated by the New Urbanist movement. Careful mixed use zoning can make commercial, residential, and light industrial areas more accessible for those traveling by foot, bicycle, or public transit, as proposed in
22578-508: The use of great crested grebe and kittiwake skins and feathers in fur clothing . The Society attracted growing support from the suburban middle-classes, and influenced the passage of the Sea Birds Preservation Act in 1869 as the first nature protection law in the world. For most of the century from 1850 to 1950, however, the primary environmental cause was the mitigation of air pollution. The Coal Smoke Abatement Society
22737-495: The use of heat pumps has grown strongly over the last two decades: in 2019, there were 15–25 heat pumps per 100 inhabitants in these countries, with ASHP the dominant heat pump technology. Similarly, earlier assumptions that ASHP would only work well in fully insulated buildings have proven wrong—even old, partially insulated buildings can be retrofitted with ASHPs and thereby strongly reduce their energy demand. Effects of EAHPs ( exhaust air heat pumps ) have also been studied within
22896-416: The use of modern technologies. The uses of timber, straw, and stone in sustainable architecture were the subject of a major exhibit at the UK's Design Museum. Sustainable architecture often incorporates the use of recycled or second hand materials, such as reclaimed lumber and recycled copper . The reduction in use of new materials creates a corresponding reduction in embodied energy (energy used in
23055-438: The use of raw resources, using biodegradable textile materials to reduce the lasting impact on the environment, and using plant dyes instead of poisonous chemicals to improve the appearance and impact of fabric. The same principle can be used inside the home, where found objects are now displayed with pride and collecting certain objects and materials to furnish a home is now admired rather than looked down upon. Take for example
23214-475: The use of solar collectors, the energy use is cut in half. The up-front cost of installing solar collectors is high, but with the annual energy savings, payback periods are relatively short. Air source heat pumps (ASHP) can be thought of as reversible air conditioners. Like an air conditioner, an ASHP can take heat from a relatively cool space (e.g. a house at 70 °F) and dump it into a hot place (e.g. outside at 85 °F). However, unlike an air conditioner,
23373-514: The use of solar shading, by means of awnings, blinds or shutters, to relieve the solar heat gain in summer and to reduce the need for artificial cooling. In addition, low energy buildings typically have a very low surface area to volume ratio to minimize heat loss. This means that sprawling multi-winged building designs (often thought to look more "organic") are often avoided in favor of more centralized structures. Traditional cold climate buildings such as American colonial saltbox designs provide
23532-453: The water, air and compost streams. Off the shelf , on-site energy recycling technologies can effectively recapture energy from waste hot water and stale air and transfer that energy into incoming fresh cold water or fresh air. Recapture of energy for uses other than gardening from compost leaving buildings requires centralized anaerobic digesters . HVAC systems are powered by motors. Copper , versus other metal conductors, helps to improve
23691-575: The “shape, thickness, [and] stiffness,” as well as mechanical properties that can mimic wood. David N. Bengston from the USDA suggests that this alternative would be more efficient than traditional wood harvesting, with future developments potentially saving on transportation energy and conserve forests. However, Bengston notes that this breakthrough would change paradigms and raises new economic and environmental questions, such as timber-dependent communities′ jobs or how conservation would impact wildfires. Despite
23850-631: Was adopted. The Kyoto Protocol was created in 1997, setting specific targets and deadlines to reduce global greenhouse gas emissions. The Kyoto Protocol has 192 signatories, including the European Union, Cook Islands, Niue, and all UN member states except Andorra, Canada, South Sudan, and the United States. In the 1990s blockades were held in Germany, the UK, France and the Netherlands to protect forests and other areas from clearing for road construction. In
24009-408: Was advocated by intellectuals such as John Ruskin , William Morris , and Edward Carpenter , who were all against consumerism , pollution and other activities that were harmful to the natural world. The movement was a reaction to the urban conditions of the industrial towns, where sanitation was awful, pollution levels intolerable and housing terribly cramped. Idealists championed the rural life as
24168-546: Was carried out.
