Hockerton Housing Project
The Hockerton Housing Project is a small community of five earth sheltered homes on the outskirts of Hockerton, Nottinghamshire, UK. The houses were designed by ‘green’ architects Professor Brenda Vale and Dr Robert Vale. Low carbon living is facilitated through the use of renewable energy, the water system, food grown on site, and the community's approach to work and transport. The homes were completed in September 1998 after three years of planning and 18 months of construction, at a cost of about £65,000. Two homes have since changed ownership on the open property market. Layout The development consists of a terrace of five single story dwellings which are earth-sheltered at the rear (North), so that the ground surface slopes and blends smoothly into the field at the back. The houses have passive solar heating (a combination of high thermal mass and the south-facing conservatory) removing the need for a space heating system and the greatest factor in lowering energy us ...

Earth Sheltering
An earth shelter, also called an earth house, earth bermed house, or underground house, is a structure (usually a house) with earth (soil) against the walls, on the roof, or that is entirely buried underground. Earth acts as thermal mass, making it easier to maintain a steady indoor air temperature and therefore reduces energy costs for heating or cooling. Earth sheltering became relatively popular after the mid-1970s, especially among environmentalists. However, the practice has been around for nearly as long as humans have been constructing their own shelters. Definition * "Earth-sheltering is ../nowiki> a generic term with the general meaning: building design in which soil plays an integral part."

Hockerton
Hockerton is a village and civil parish in Nottinghamshire. It is 2 miles from the town of Southwell on the A617 between Newark and Mansfield. Fewer than 60 houses are situated around the church, the ''Spread Eagle'' pub and village hall. The population at the 2011 Census was 146. The local properties range from the carbon neutral housing of the Hockerton Housing Project to converted barns, 1960s and 1970s housing together with much older houses and a 19th-century Rectory. The parish church of St Nicholas is Norman with an aisleless nave and a 14th-century chancel. Part of the village contains Hockerton Housing Project. The Hockerton Housing Project is the UK's first earth sheltered, self-sufficient ecological housing development. A group of residents formed an Industrial and Provident Society (IPS) called Sustainable Hockerton Limited in 2009.

Architects
An architect is a person who plans, designs and oversees the construction of buildings. To practice architecture means to provide services in connection with the design of buildings and the space within the site surrounding the buildings that have human occupancy or use as their principal purpose. Etymologically, the term architect derives from the Latin ''architectus'', which derives from the Greek (''arkhi-'', chief + ''tekton'', builder), i.e., chief builder. The professional requirements for architects vary from place to place. An architect's decisions affect public safety, and thus the architect must undergo specialized training consisting of advanced education and a ''practicum'' (or internship) for practical experience to earn a license to practice architecture. Practical, technical, and academic requirements for becoming an architect vary by jurisdiction, though the formal study of architecture in academic institutions has played a pivotal role in the development of the ...

Brenda And Robert Vale
Professor Brenda Vale and Doctor Robert Vale are architects, writers, pioneer researchers, and experts in the field of sustainable housing. Background After studying architecture together at the University of Cambridge, in 1975 the Vales published "The Autonomous House", a technical guide for developing housing solutions that are energy-self-sufficient, environmentally friendly, relatively easy to maintain, and have a traditional appearance. The book has been translated into five languages and is widely recognised as a basic text in the field of green building. Through the 1980s the Vales designed a number of commercial buildings in England, notably the thick-walled, super-insulated Woodhouse Medical Centre in Sheffield. In the 1990s the Vales completed two important green building projects in Nottinghamshire: the first in 1993, the first autonomous building in the United Kingdom, a four-bedroom house for themselves in the historic town of Southwell. Their book "The New ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Passive Solar
In passive solar building design, windows, walls, and floors are made to collect, store, reflect, and distribute solar energy, in the form of heat in the winter and reject solar heat in the summer. This is called passive solar design because, unlike active solar heating systems, it does not involve the use of mechanical and electrical devices. The key to designing a passive solar building is to best take advantage of the local climate performing an accurate site analysis. Elements to be considered include window placement and size, and glazing type, thermal insulation, thermal mass, and shading. Passive solar design techniques can be applied most easily to new buildings, but existing buildings can be adapted or "retrofitted". Passive energy gain ''Passive solar'' technologies use sunlight without active mechanical systems (as contrasted to ''active solar'', which uses thermal collectors). Such technologies convert sunlight into usable heat (in water, air, and thermal mass), cau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thermal Mass
In building design, thermal mass is a property of the mass of a building that enables it to store heat and provide inertia against temperature fluctuations. It is sometimes known as the thermal flywheel effect. The thermal mass of heavy structural elements can be designed to work alongside a construction's lighter thermal resistance components to create energy efficient buildings. For example, when outside temperatures are fluctuating throughout the day, a large thermal mass within the insulated portion of a house can serve to "flatten out" the daily temperature fluctuations, since the thermal mass will absorb thermal energy when the surroundings are higher in temperature than the mass, and give thermal energy back when the surroundings are cooler, without reaching thermal equilibrium. This is distinct from a material's insulative value, which reduces a building's thermal conductivity, allowing it to be heated or cooled relatively separately from the outside, or even just retain ...

Wind Turbines
A wind turbine is a device that converts the kinetic energy of wind into electrical energy. Hundreds of thousands of large turbines, in installations known as wind farms, now generate over 650 gigawatts of power, with 60 GW added each year. Wind turbines are an increasingly important source of intermittent renewable energy, and are used in many countries to lower energy costs and reduce reliance on fossil fuels. One study claimed that, wind had the "lowest relative greenhouse gas emissions, the least water consumption demands and the most favorable social impacts" compared to photovoltaic, hydro, geothermal, coal and gas energy sources. Smaller wind turbines are used for applications such as battery charging for auxiliary power for boats or caravans, and to power traffic warning signs. Larger turbines can contribute to a domestic power supply while selling unused power back to the utility supplier via the electrical grid. Wind turbines are manufactured in a wide range of ...

Solar Photovoltaic
A photovoltaic system, also PV system or solar power system, is an electric power system designed to supply usable solar power by means of photovoltaics. It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity, a solar inverter to convert the output from direct to alternating current, as well as mounting, cabling, and other electrical accessories to set up a working system. It may also use a solar tracking system to improve the system's overall performance and include an integrated battery. PV systems convert light directly into electricity, and are not to be confused with other solar technologies, such as concentrated solar power or solar thermal, used for heating and cooling. A solar array only encompasses the ensemble of solar panels, the visible part of the PV system, and does not include all the other hardware, often summarized as balance of system (BOS). PV systems range from small, rooftop-mounted or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 generates no pollution and no 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 in PV system m ...

Renewables Obligation
The Renewables Obligation (RO) is designed to encourage generation of electricity from eligible renewable sources in the United Kingdom. It was introduced in England and Wales and in a different form (the Renewables Obligation (Scotland)) in Scotland in April 2002 and in Northern Ireland in April 2005, replacing the Non-Fossil Fuel Obligation which operated from 1990. The RO places an obligation on licensed electricity suppliers in the United Kingdom to source an increasing proportion of electricity from renewable sources, similar to a renewable portfolio standard. In 2010/11 it is 11.1% (4.0% in Northern Ireland). This figure was initially set at 3% for the period 2002/03 and under current political commitments will rise to 15.4% (6.3% in Northern Ireland) by the period 2015/16 and then it runs until 2037 (2033 in Northern Ireland). The extension of the scheme from 2027 to 2037 was declared on 1 April 2010 and is detailed in the National Renewable Energy Action Plan. Since its i ...

Feed-in Tariff
A feed-in tariff (FIT, FiT, standard offer contract,Couture, T., Cory, K., Kreycik, C., Williams, E., (2010)Policymaker's Guide to Feed-in Tariff Policy Design National Renewable Energy Laboratory, U.S. Dept. of Energy advanced renewable tariff, or renewable energy payments) is a policy mechanism designed to accelerate investment in renewable energy technologies by offering long-term contracts to renewable energy producers. This means promising renewable energy producers an above-market price and providing price certainty and long-term contracts that help finance renewable energy investments. Typically, FITs award different prices to different sources of renewable energy in order to encourage development of one technology over another. For example, technologies such as wind power and solar PV are awarded a higher price per kWh than tidal power. FITs often include a "degression": a gradual decrease of the price or tariff in order to follow and encourage technological cost reductions ...
