National Energy Foundation
The National Energy Foundation (NEF) is an independent British charity, established to improve the use of energy in buildings. Aims The charity aims to ''improve the use of energy in buildings''. This statement simplified the earlier stated mission to mobilise individuals, businesses and communities to make their contribution to reducing carbon dioxide emissions through energy efficiency and use of sustainable energy sources (notably renewable energy) to maintain affordable energy services and combat global climate change. Activities NEF was founded in 1988 by Milton Keynes Development Corporation to preserve for the future benefit of the UK public some of the energy initiatives that had been undertaken within the new city. Its initial projects included extending a technical home energy label (known as the Milton Keynes Energy Cost Index – MKECI) into a more generally applicable home energy rating called the National Home Energy Rating (NHER), and technical energy mon ...

Charitable Organization
A charitable organization or charity is an organization whose primary objectives are philanthropy and social well-being (e.g. educational, Religion, religious or other activities serving the public interest or common good). The legal definition of a charitable organization (and of charity) varies between countries and in some instances regions of the country. The Charity regulators, regulation, the tax treatment, and the way in which charity law affects charitable organizations also vary. Charitable organizations may not use any of their funds to profit individual persons or entities. However, some charitable organizations have come under scrutiny for spending a disproportionate amount of their income to pay the salaries of their leadership. Financial figures (e.g. tax refunds, revenue from fundraising, revenue from the sale of goods and services or revenue from investment, and funds held in reserve) are indicators to assess the financial sustainability of a charity, especiall ...

Duke Of Edinburgh's Award
The Duke of Edinburgh's Award (commonly abbreviated DofE) is a youth awards programme founded in the United Kingdom in 1956 by the Prince Philip, Duke of Edinburgh, which has since expanded to 144 nations. The awards recognise adolescents and young adults for completing a series of self-improvement exercises modelled on Kurt Hahn's solutions to his "Kurt Hahn#Six Declines of Modern Youth, Six Declines of Modern Youth". History In February 1955, The Duke of Edinburgh's Award was first announced. It was at first "for boys aged 15 to 18". It was first administered, and largely designed, by John Hunt, Baron Hunt, John Hunt, who had led the 1953 British Mount Everest expedition, first successful ascent of Mount Everest in 1953, and had retired from the army to run The Duke of Edinburgh's Award. It was designed to attract boys who had not been interested in joining one of the main British youth movements, such as the Scout Association. In the first 12 months, 7,000 boys had enroll ...

Bletchley
Bletchley is a constituent town of Milton Keynes, Buckinghamshire, England, in the south-west of the city, split between the civil parishes in England, civil parishes of Bletchley and Fenny Stratford and West Bletchley, which In 2011 had a combined population of 37,114. Bletchley is best known for Bletchley Park, the headquarters of Britain's World War II codebreaking organisation, and now a major tourist attraction. The National Museum of Computing is also located on the Park. History Origins and early modern history The town name is Old English, Anglo-Saxon and means ''Blæcca's clearing''. It was first recorded in Manorialism, manorial rolls in the 12th century as ''Bicchelai'', then later as ''Blechelegh'' (13th century) and ''Blecheley'' (14th–16th centuries). Just to the south of Fenny Stratford, there was Romano-British town, ''Magiovinium, M'' on either side of Watling Street, a Roman road. Bletchley was originally a minor village on the outskirts of Fenny Stratfo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Condensing Boiler
Condensing boilers are water heaters typically used for heating systems that are fueled by gas or oil. When operated in the correct circumstances, a heating system can achieve high efficiency (greater than 90% on the higher heating value) by condensing water vapour found in the exhaust gases in a heat exchanger to preheat the circulating water. This recovers the latent heat of vaporisation, which would otherwise have been wasted. The condensate is sent to a drain. In many countries, the use of condensing boilers is compulsory or encouraged with financial incentives. For the condensation process to work properly, the return temperature of the circulating water must be around or below, so condensing boilers are often run at lower temperatures, around or below, which can require larger pipes and radiators than non-condensing boilers. Nevertheless, even partial condensing is more efficient than a conventional non-condensing boiler. Operational principle In a conventional boiler, ...

Commission For New Towns
English Partnerships (EP) was the national regeneration agency for England, performing a similar role on a national level to that fulfilled by regional development agencies on a regional level. On 1 December 2008 its powers passed to a successor body, the new Homes and Communities Agency. It was responsible for land acquisition and assembly and major development projects, alone or in joint partnership with private sector developers. It was particularly active in major regeneration areas such as the Thames Gateway and in expansion areas such as Milton Keynes, where the Deputy Prime Minister (acting as Environment Minister) removed planning from local control and appointed them as the statutory planning authority. It was a non-departmental public body funded through the Department for Communities and Local Government (CLG), and was previously by the Office of the Deputy Prime Minister (the predecessor department to CLG).

Photovoltaics
Photovoltaics (PV) is the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon studied in physics, photochemistry, and electrochemistry. The photovoltaic effect is commercially used for electricity generation and as photosensors. A photovoltaic system employs solar modules, each comprising a number of solar cells, which generate electrical power. PV installations may be ground-mounted, rooftop-mounted, wall-mounted or floating. The mount may be fixed or use a solar tracker to follow the sun across the sky. Photovoltaic technology helps to mitigate climate change because it emits much less carbon dioxide than fossil fuels. Solar PV has specific advantages as an energy source: once installed, its operation does not generate any pollution or any greenhouse gas emissions; it shows scalability in respect of power needs and silicon has large availability in the Earth's crust, although other materials required ...

Light Tube
Light tubes (also known as solar pipes, tubular skylights or sun tunnels) are structures that transmit or distribute natural or artificial light for the purpose of illumination and are examples of optical waveguides. In their application to daylighting, they are also often called tubular daylighting devices, sun pipes, sun scopes, or daylight pipes. They can be divided into two broad categories: hollow structures that contain the light with reflective surfaces; and transparent solids that contain the light by total internal reflection. Principles of nonimaging optics govern the flow of light through them. Types IR light tubes Manufacturing custom designed infrared light pipes, hollow waveguides and homogenizers is non-trivial. This is because these are tubes lined with a highly polished infrared reflective coating of gold, which can be applied thick enough to permit these tubes to be used in highly corrosive atmospheres. Carbon black can be applied to certain parts of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wood Pellets
Pellet fuels (or pellets) are a type of solid fuel made from compressed organic material. Pellets can be made from any one of five general categories of Biomass (energy), biomass: industrial waste and co-products, food waste, Crop residue, agricultural residues, energy crops, and Wood preservation#Chemical, untreated lumber. Wood pellets are the most common type of pellet fuel and are generally made from compacted sawdust and related industrial wastes from the Lumber mill, milling of lumber, manufacture of wood products and furniture, and construction. Other industrial waste sources include empty fruit bunches, palm kernel shells, coconut shells, and tree tops and branches discarded during logging operations. So-called "black pellets" are made of biomass, refined to resemble hard coal and were developed to be used in existing coal-fired Power station, power plants. Pellets are categorized by their Heat of combustion, heating value, moisture and Wood ash, ash content, and dimensions. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solar Water Heating
Solar water heating (SWH) is water heating, heating water by sunlight, using a solar thermal collector. A variety of configurations are available at varying cost to provide solutions in different climates and latitudes. SWHs are widely used for residential and some industrial applications. A Sun-facing collector heats a working fluid that passes into a storage system for later use. SWH are active (pumped) and passive (Natural convection, convection-driven). They use water only, or both water and a working fluid. They are heated directly or via light-concentrating mirrors. They operate independently or as hybrids with electric or gas heaters. In large-scale installations, mirrors may concentrate sunlight into a smaller collector. At the end of 2023, global solar hot water thermal capacity was 560 GWth, GWth, a 3% increase from 2022. The market is dominated by Solar power in China, China, the Solar power in the United States, United States and Solar power in Turkey, Turkey. Barbad ...

Geothermal Heat Pump
A ground source heat pump (also geothermal heat pump) is a heating/cooling system for buildings that use a type of heat pump to transfer heat to or from the ground, taking advantage of the relative constancy of temperatures of the earth through the seasons. Ground-source heat pumps (GSHPs)or geothermal heat pumps (GHP), as they are commonly termed in North Americaare among the most energy-efficient technologies for providing HVAC and water heating, using less energy than can be achieved by use of resistive electric heaters. Efficiency is given as a coefficient of performance (CoP) which is typically in the range 3-6, meaning that the devices provide 3-6 units of heat for each unit of electricity used. Setup costs are higher than for other heating systems, due to the requirement of installing ground loops over large areas or of drilling bore holes, hence ground source is often installed when new blocks of flats are built. Air-source heat pumps have lower set-up costs but have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
