Ventilation (architecture)
Ventilation is the intentional introduction of outdoor air into a space. Ventilation is mainly used to control indoor air quality by diluting and displacing indoor pollutants; it can also be used to control indoor temperature, humidity, and air motion to benefit thermal comfort, satisfaction with other aspects of indoor environment, or other objectives. The intentional introduction of outdoor air is usually categorized as either mechanical ventilation, natural ventilation, or mixed-mode ventilation (hybrid ventilation). * Mechanical ventilation is the intentional fan driven flow of outdoor air into a building. Mechanical ventilation systems may include supply fans (which push outdoor air into a building), exhaust fans (which draw air out of building and thereby cause equal ventilation flow into a building), or a combination of both. Mechanical ventilation is often provided by equipment that is also used to heat and cool a space. * Natural ventilation is the intentional passive fl ...

Building Insulation
Building insulation is any object in a building used as insulation for thermal management. While the majority of insulation in buildings is for thermal purposes, the term also applies to acoustic insulation, fire insulation, and impact insulation (e.g. for vibrations caused by industrial applications). Often an insulation material will be chosen for its ability to perform several of these functions at once. Insulation is an important economic and environmental investment for buildings. By installing insulation, buildings use less energy for heating and cooling and occupants experience less thermal variability. Retrofitting buildings with further insulation is an important climate change mitigation tactic, especially in geographies where energy production is carbon-intensive. Local and national governments and utilities often have a mix of incentives and regulations to encourage insulation efforts on new and renovated buildings as part of efficiency programs in order to red ...

SkyCity Challenge
SkyCity (originally known as the Eye of the Needle) was a revolving restaurant and bar situated atop the Space Needle in Seattle, Washington, United States. Description and history The restaurant featured a carousel (or ring-shaped) dining floor on which sat patrons' tables, chairs, and dining booths. Its floor revolved on a track and wheel system weighing roughly 125 tons, moving at a rate of one revolution every 47 minutes. It was the oldest operating revolving restaurant in the world at the time of its closure. Due to the balance and precision of its design, the floor's rotation is accomplished using just a single 1½-horsepower motor. The restaurant was designed by John Graham & Company and styled after the La Ronde they had built atop the Ala Moana Center in 1963. SkyCity was a fine dining restaurant with a casual dress code and served Pacific Northwest cuisine and new American cuisine, providing local seafood, steak, chicken and vegetarian items among others.

Mini Sky City
Mini Sky City (小天城) is a 57-story, 204m high building in Changsha, the capital of Hunan province in China. It was built in 19 days in 2015 by Broad Sustainable Building, a subsidiary of China's Broad Group, using a modular construction system. The company has ambitions to use similar techniques to build a much larger project, Sky City, which is intended to be 220 stories tall. In 2017 mini Sky City was involved in international architectural competition SkyCity Challenge SkyCity (originally known as the Eye of the Needle) was a revolving restaurant and bar situated atop the Space Needle in Seattle, Washington, United States.

Sky City One
Sky City (), or Sky City One, was an planned skyscraper A skyscraper is a tall continuously habitable building having multiple floors. Modern sources currently define skyscrapers as being at least or in height, though there is no universally accepted definition. Skyscrapers are very tall high-ris ... in the city of Changsha, Hunan in south-central China. The prospective builders, Broad Sustainable Building, estimated it would take just 90 days to construct. Including the 120 days required for prefabrication before on-site work commenced, the sum of time needed was 210 days. Pre-construction activities were halted in August 2013 after government regulators required additional approvals. Broad Sustainable Building had intended to build a skyscraper, but the local government wanted the world's tallest building, hence the current plans. The company has constructed 20 buildings in China using the same method and has several franchise partners globally. It has a planned helip ...

Absorption Chiller
An absorption refrigerator is a refrigerator that uses a heat source (e.g., Solar thermal energy, solar energy, a fossil-fueled flame, waste heat from factories, or district heating systems) to provide the energy needed to drive the cooling process. The system uses two coolants, the first of which performs evaporative cooling and is then absorbed into the second coolant; heat is needed to reset the two coolants to their initial states. The principle can also be used to air conditioning, air-condition buildings using the waste heat from a gas turbine or water heating, water heater. Using waste heat from a gas turbine makes the turbine very efficient because it first produces electricity, then hot water, and finally, air-conditioning—trigeneration. Absorption refrigerators are commonly used in recreational vehicles (RVs), Popup camper, campers, and Caravan (towed trailer), caravans because the heat required to power them can be provided by a propane fuel burner, by a low-voltage DC ...

Boiler
A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications, including water heating, central heating, boiler-based power generation, cooking, and sanitation. Heat sources In a fossil fuel power plant using a steam cycle for power generation, the primary heat source will be combustion of coal, oil, or natural gas. In some cases byproduct fuel such as the carbon monoxide rich offgasses of a coke battery can be burned to heat a boiler; biofuels such as bagasse, where economically available, can also be used. In a nuclear power plant, boilers called steam generators are heated by the heat produced by nuclear fission. Where a large volume of hot gas is available from some process, a heat recovery steam generator or recovery boiler can use the heat to produce steam, with little or no extra fuel consumed; such a configuration is common ...

Cultural Revolution
The Cultural Revolution, formally known as the Great Proletarian Cultural Revolution, was a sociopolitical movement in the People's Republic of China (PRC) launched by Mao Zedong in 1966, and lasting until his death in 1976. Its stated goal was to preserve Chinese communism by purging remnants of capitalist and traditional elements from Chinese society. The Revolution marked the effective commanding return of Mao –who was still the Chairman of the Chinese Communist Party (CCP)– to the centre of power, after a period of self-abstention and ceding to less radical leadership in the aftermath of the Mao-led Great Leap Forward debacle and the Great Chinese Famine (1959–1961). The Revolution failed to achieve its main goals. Launching the movement in May 1966 with the help of the Cultural Revolution Group, Mao charged that bourgeois elements had infiltrated the government and society with the aim of restoring capitalism. Mao called on young people to "bombard the headqu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
