Green building refers to both a structure and the application of processes that are environmentally responsible and resource-efficient throughout a building's life-cycle: from planning to design, construction, operation, maintenance, renovation, and demolition. This requires close cooperation of the contractor, the architects, the engineers, and the client at all project stages. The Green Building practice expands and complements the classical building design concerns of economy, utility, durability, and comfort. Green building also refers to saving resources to the maximum extent, including energy saving, land saving, water saving, material saving, etc., during the whole life cycle of the building, protecting the environment and reducing pollution, providing people with healthy, comfortable and efficient use of space, and being in harmony with nature Buildings that live in harmony. Green building technology focuses on low consumption, high efficiency, economy, environmental protection, integration and optimization.’
A low-energy house is characterized by an energy-efficient design and technical features which enable it to provide high living standards and comfort with low energy consumption and carbon emissions. Traditional heating and active cooling systems are absent, or their use is secondary. Low-energy buildings may be viewed as examples of sustainable architecture. Low-energy houses often have active and passive solar building design and components, which reduce the house's energy consumption and minimally impact the resident's lifestyle. Throughout the world, companies and non-profit organizations provide guidelines and issue certifications to guarantee the energy performance of buildings and their processes and materials. Certifications include passive house, BBC - Bâtiment Basse Consommation - Effinergie (France), zero-carbon house (UK), and Minergie (Switzerland).
An energy-plus building produces more energy from renewable energy sources, over the course of a year, than it imports from external sources. This is achieved using a combination of microgeneration technology and low-energy building techniques, such as: passive solar building design, insulation and careful site selection and placement. A reduction of modern conveniences can also contribute to energy savings, however many energy-plus houses are almost indistinguishable from a traditional home, preferring instead to use highly energy-efficient appliances, fixtures, etc., throughout the house.
Passive house is a voluntary standard for energy efficiency in a building, which reduces the building's ecological footprint. It results in ultra-low energy buildings that require little energy for space heating or cooling. A similar standard, MINERGIE-P, is used in Switzerland. The standard is not confined to residential properties; several office buildings, schools, kindergartens and a supermarket have also been constructed to the standard. The design is not an attachment or supplement to architectural design, but a design process that integrates with architectural design. Although it is generally applied to new buildings, it has also been used for refurbishments.
Sustainable architecture is architecture that seeks to minimize 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.
Leadership in Energy and Environmental Design (LEED) is a green building certification program used worldwide. Developed by the non-profit U.S. Green Building Council (USGBC), it includes a set of rating systems for the design, construction, operation, and maintenance of green buildings, homes, and neighborhoods, which aims to help building owners and operators be environmentally responsible and use resources efficiently.
A Zero Energy Building (ZEB), also known as a Net Zero Energy (NZE) building, is a building with net zero energy consumption, meaning the total amount of energy used by the building on an annual basis is equal to the amount of renewable energy created on the site or in other definitions by renewable energy sources offsite, using technology such as heat pumps, high efficiency windows and insulation, and solar panels.
The Association for Environment Conscious Building (AECB) is the leading network for sustainable building professionals in the United Kingdom. Membership of the AECB includes local authorities, housing associations, builders, architects, designers, consultants and manufacturers. The association was founded in 1989 to increase awareness within the construction industry of the need to respect, protect, preserve and enhance the environment and to develop, share and promote best practice in environmentally sustainable building.
Green buildings in Australia are assessed and rated by a variety of government and independent ratings systems.
Sonnenschiff is a large integrated office and retail building in Freiburg im Breisgau, Germany. It was built in 2004 in the city's Vauban quarter as part of the Solar Settlement at Schlierberg. Sonnenschiff was designed by the architect Rolf Disch and generates four times more energy than it uses.
Rolf Disch is a German architect, solar energy pioneer and environmental activist. Born in Freiburg im Breisgau, Germany, Disch has dedicated particular focus to regional renewable and sustainable energy.
The Heliotrope is a design of environmentally friendly housing by German architect Rolf Disch. Three such buildings exist in Germany; the first experimental version was built in 1994 as the architect's home in Freiburg im Breisgau, while the other two were used as exhibition buildings for the Hansgrohe company in Offenburg and a dentist's lab in Hilpoltstein in Bavaria.
The Solar Settlement at Schlierberg is a 59-home PlusEnergy housing community in Freiburg, Germany. Solar architect Rolf Disch wanted to apply his PlusEnergy concept, created originally with his Heliotrope home, to mass residential production. The residential complex won such awards as House of the Year (2002), Residential PV solar integration award (2002), and "Germany's most beautiful housing community" (2006). It is one of the first housing communities in the world in which all the homes produce a positive energy balance and which is emissions-free and CO2 neutral.
Both the public and private sectors in the United Kingdom promote green building. Presently, there are already regulatory mechanisms in place that establish Britain's commitment to this kind of building construction. The government, for instance, set out a target that by 2016, all new homes will have zero carbon emission and it also includes a progressive tightening of energy efficiency regulations by 25 percent and 44 percent in 2010 and 2013, respectively. The UK Building Regulations set requirements for insulation levels and other aspects of sustainability in building construction.
Environmentally sustainable design is the philosophy of designing physical objects, the built environment, and services to comply with the principles of ecological sustainability and also aimed at improving the health and comfortability of occupants in a building. Sustainable design seeks to reduce negative impacts on the environment, the health and well-being of building occupants, thereby improving building performance. The basic objectives of sustainability are to reduce the consumption of non-renewable resources, minimize waste, and create healthy, productive environments.
A green home is a type of house designed to be environmentally sustainable. Green homes focus on the efficient use of "energy, water, and building materials". A green home may use sustainably sourced, environmentally friendly, and/or recycled building materials. It may include sustainable energy sources such as solar or geothermal, and be sited to take maximum advantage of natural features such as sunlight and tree cover to improve energy efficiency.
Vauban is a neighbourhood (Stadtteil) to the south of the town centre in Freiburg, Germany. It was built as "a sustainable model district" on the site of a former French military base named after Sébastien Le Prestre de Vauban, the 17th century French Marshal who built fortifications in Freiburg while the region was under French rule. Construction began in 1998, and the first two residents arrived in 2001.
Kenneth L. Haggard is an American architect, educator, and solar pioneer who has designed more than 300 buildings and seen more than 200 built. He is a licensed architect in California and Florida. He and his partner Polly Cooper were awarded the American Solar Energy Society Passive Solar Pioneer Award in 1996. They have been leaders in both passive solar architecture and the rediscovery of straw bale building.
