Natural Ventilation
Passive ventilation is the process of supplying air to and removing air from an indoor space without using mechanical systems. It refers to the flow of external air to an indoor space as a result of pressure differences arising from natural forces. There are two types of natural ventilation occurring in buildings: '' wind driven ventilation'' and ''buoyancy-driven ventilation''. Wind driven ventilation arises from the different pressures created by wind around a building or structure, and openings being formed on the perimeter which then permit flow through the building. Buoyancy-driven ventilation occurs as a result of the directional buoyancy force that results from temperature differences between the interior and exterior. Since the internal heat gains which create temperature differences between the interior and exterior are created by natural processes, including the heat from people, and wind effects are variable, naturally ventilated buildings are sometimes called "bre ...

List Of Tallest Buildings In Germany
This list ranks buildings in Germany that stand at least tall. Only habitable buildings are ranked, which excludes radio masts and towers, observation towers, Steeple (architecture), steeples, chimneys and other tall architectural structures. The construction of high-rise buildings is not common in German cities, and especially not in the city centres, where traditionally steeples are the tallest structures. Due to its economic profile as an international financial centre, only Frankfurt has developed a skyline of high-rise buildings and skyscrapers in its city centre. Out of a total of 22 skyscrapers in Germany, meaning buildings at least tall, 20 are located in Frankfurt. The development of high-rises in Germany began in 1915, with the Zeiss Bau 15 in Jena. Notable examples of early high-rise buildings include the Wilhelm Marx House in Düsseldorf, the :de:Borsig (Unternehmen)#Borsigturm, Borsigturm and :de:Ullsteinhaus, Ullsteinhaus in Berlin, the Hansahochhaus in Cologne, ...

List Of Tallest Buildings In Frankfurt
Frankfurt, Germany, is one of the few European cities with a large cluster of high rise buildings in its downtown area. In many other European cities, skyscraper construction was not well received in the past due to the historical value of existing buildings. For this reason, Frankfurt is sometimes referred to as "Mainhattan" (a Portmanteau word, portmanteau of the local Main (river), Main river and Manhattan), and Chicago am Main. The List of tallest buildings in Germany, 15 tallest buildings in Germany are located in Frankfurt. The tallest structure in Frankfurt is the Europaturm, which rises . However, the tower is not generally considered a high-rise building as it does not have successive floors that can be occupied. The tallest habitable building in Frankfurt is the Commerzbank Tower, which rises and has 56 floors. As of December 2024, it is the List of tallest buildings in Europe, 22nd-tallest building in Europe and the second tallest building in the European Union. M ...

Conference Hall
A conference hall, conference room, or meeting room is a room provided for singular events such as business conferences and meetings. Room It is commonly found at large hotels and convention centers though many other establishments, including even hospitals. Sometimes other rooms are modified for large conferences such as arenas or concert halls. Aircraft have been fitted out with conference rooms. Conference rooms can be windowless for security purposes. An example of one such room is in the Pentagon, known as the ''Tank''. Typically, the facility provides furniture, overhead projectors, stage lighting, and sound system. Smoking is normally prohibited in conference halls, even when other parts of buildings permit smoking. Sometimes the term 'conference hall' is used synonymously with ' conference center' as, for example, in 'Bandaranaike Memorial International Conference Hall'. Some meeting rooms come equipped with booking management software, depending on the needs of the co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CTBUH Skyscraper Award
The Tall Building Awards or CTBUH Awards recognizes projects and individuals who have made an extraordinary contribution to the advancement of tall buildings and urban environment, as well as achieving sustainability at the highest and broadest level.

Kilowatt-hour
A kilowatt-hour ( unit symbol: kW⋅h or kW h; commonly written as kWh) is a non-SI unit of energy equal to 3.6 megajoules (MJ) in SI units, which is the energy delivered by one kilowatt of power for one hour. Kilowatt-hours are a common billing unit for electrical energy supplied by electric utilities. Metric prefixes are used for multiples and submultiples of the basic unit, the watt-hour (3.6 kJ). Definition The kilowatt-hour is a composite unit of energy equal to one kilowatt (kW) multiplied by (i.e., sustained for) one hour. The International System of Units (SI) unit of energy meanwhile is the joule (symbol J). Because a watt is by definition one joule per second, and because there are 3,600 seconds in an hour, one kWh equals 3,600 kilojoules or 3.6 MJ."Half-high dots or spaces are used to express a derived unit formed from two or more other units by multiplication.", Barry N. Taylor. (2001 ed.''The International System of Units.'' (Special publicatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geothermal Energy
Geothermal energy is thermal energy extracted from the crust (geology), crust. It combines energy from the formation of the planet and from radioactive decay. Geothermal energy has been exploited as a source of heat and/or electric power for millennia. Geothermal heating, using water from hot springs, for example, has been used for bathing since Paleolithic times and for space heating since Roman times. Geothermal power (generation of electricity from geothermal energy), has been used since the 20th century. Unlike wind and solar energy, geothermal plants produce power at a constant rate, without regard to weather conditions. Geothermal resources are theoretically more than adequate to supply humanity's energy needs. Most extraction occurs in areas near tectonic plate boundaries. The cost of generating geothermal power decreased by 25% during the 1980s and 1990s. Technological advances continued to reduce costs and thereby expand the amount of viable resources. In 2021, the US ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radiant Heating And Cooling
Radiant heating and cooling is a category of HVAC technologies that exchange heat by both convection and radiation with the environments they are designed to heat or cool. There are many subcategories of radiant heating and cooling, including: "radiant ceiling panels",ISO. (2012). ''ISO 11855:2012—Building environment design-Design, dimensioning, installation and control of embedded radiant heating and cooling systems''. International Organization for Standardization. "embedded surface systems", "thermally active building systems", and infrared heaters. According to some definitions, a technology is only included in this category if radiation comprises more than 50% of its heat exchange with the environment; therefore technologies such as radiators and chilled beams (which may also involve radiation heat transfer) are usually not considered radiant heating or cooling. Within this category, it is practical to distinguish between high temperature radiant heating (devices with em ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
