Passive Houses
"Passive house" (german: Passivhaus) 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. In 2008, estimates of the number of passive house buildings around the world ranged from 15,000 to 20,000 structures. In 2016, there were approximately 60,000 such certified structures of all types worldwide. The vast majority of passive structures have been built in German-speaking cou ...

House
A house is a single-unit residential building. It may range in complexity from a rudimentary hut to a complex structure of wood, masonry, concrete or other material, outfitted with plumbing, electrical, and heating, ventilation, and air conditioning systems.Schoenauer, Norbert (2000). ''6,000 Years of Housing'' (rev. ed.) (New York: W.W. Norton & Company). Houses use a range of different roofing systems to keep precipitation such as rain from getting into the dwelling space. Houses may have doors or locks to secure the dwelling space and protect its inhabitants and contents from burglars or other trespassers. Most conventional modern houses in Western cultures will contain one or more bedrooms and bathrooms, a kitchen or cooking area, and a living room. A house may have a separate dining room, or the eating area may be integrated into another room. Some large houses in North America have a recreation room. In traditional agriculture-oriented societies, domestic animals such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Architectural Firm
In the United States, an architectural firm or architecture firm is a business that employs one or more licensed architects and practices the profession of architecture; while in South Africa, the United Kingdom, Ireland, Denmark and other countries, an architectural firm is a company that offers architectural services. History Architects (or master builders) have existed since early in recorded history. The earliest recorded architects include Imhotep (c. 2600 BCE) and Senemut (c. 1470 BCE). No writings exist to describe how these architects performed their work. However, as nobles it is reasonable to assume they had staffs of assistants and retainers to help refine and implement their work. The oldest surviving book on architecture, ''De architectura'' by the Roman architect Vitruvius describes the design and construction of towns, buildings, clocks, and machines, but provides no information about the organisation of the architect's assistants. It is generally accepted that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Row House
In architecture and city planning, a terrace or terraced house (British English, UK) or townhouse (American English, US) is a form of medium-density housing that originated in Europe in the 16th century, whereby a row of attached dwellings party wall, share side walls. In the United States and Canada they are also known as row houses or row homes, found in older cities such as Philadelphia, Baltimore, and Toronto. Terrace housing can be found throughout the world, though it is in abundance in Europe and Latin America, and extensive examples can be found in the United Kingdom, United States, Canada, and Australia. The Place des Vosges in Paris (1605–1612) is one of the early examples of the style. Sometimes associated with the working class, historical and reproduction terraces have increasingly become part of the process of gentrification in certain inner-city areas. Origins and nomenclature Though earlier Gothic Architecture, Gothic ecclesiastical examples, such as Vicars' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manhattan Project
The Manhattan Project was a research and development undertaking during World War II that produced the first nuclear weapons. It was led by the United States with the support of the United Kingdom and Canada. From 1942 to 1946, the project was under the direction of Major General Leslie Groves of the United States Army Corps of Engineers, U.S. Army Corps of Engineers. Nuclear physicist Robert Oppenheimer was the director of the Los Alamos Laboratory that designed the actual bombs. The Army component of the project was designated the Manhattan District as its first headquarters were in Manhattan; the placename gradually superseded the official codename, Development of Substitute Materials, for the entire project. Along the way, the project absorbed its earlier British counterpart, Tube Alloys. The Manhattan Project began modestly in 1939, but grew to employ more than 130,000 people and cost nearly US$2 billion (equivalent to about $ billion in ). Over 90 percent of th ...

William Shurcliff
William Asahel Shurcliff (March 27, 1909 – June 20, 2006) was an American physicist. Biography He received his BA cum laude in 1930, a PhD in Physics in 1934, and a degree in Business Administration in 1935, all from Harvard University. In the 1930s he worked at the Spectrophotometric Laboratory at the Calco Chemical Division of the American Cyanamid Company. Atomic bomb In 1942 he joined the staff of the Office of Scientific Research and Development, where he worked in the Liaison Office, processing technical information obtained from overseas and routing it to divisions within US government research where it could be useful. In May 1942 he was chosen by his boss, Vannevar Bush, to be part of S-1 Section, which would become the Manhattan Project to make the atomic bomb. Shurcliff's role was specifically to be a censor of patents: he would review patent applications from the private sector which appeared to impinge on topics being developed in secret by the government, and put t ...

Superinsulation
Superinsulation is an approach to building design, construction, and retrofitting that dramatically reduces heat loss (and gain) by using much higher levels of insulation and airtightness than normal. Superinsulation is one of the ancestors of the passive house approach. Definition There is no universally agreed definition of superinsulation, but superinsulated buildings typically include: * Very high levels of insulation, typically R-40 (RSI-7) walls and R-60 (RSI-10.6) roof, corresponding to SI U-values of 0.15 and 0.1 W/(m²·K) respectively) * Details to ensure insulation continuity where walls meet roofs, foundations, and other walls * Airtight construction, especially around doors and windows to prevent air infiltration pushing heat in or out * a heat recovery ventilation system to provide fresh air * No large windows facing any particular direction * Much smaller than conventional heating system, sometimes just a small backup heater Nisson & Dutt (1985) suggest that a ...

Solar Gain
Solar gain (also known as solar heat gain or passive solar gain) is the increase in thermal energy of a space, object or structure as it absorbs incident solar radiation. The amount of solar gain a space experiences is a function of the total incident solar irradiance and of the ability of any intervening material to transmit or resist the radiation. Objects struck by sunlight absorb its visible and short-wave infrared components, increase in temperature, and then re-radiate that heat at longer infrared wavelengths. Though transparent building materials such as glass allow visible light to pass through almost unimpeded, once that light is converted to long-wave infrared radiation by materials indoors, it is unable to escape back through the window since glass is opaque to those longer wavelengths. The trapped heat thus causes solar gain via a phenomenon known as the greenhouse effect. In buildings, excessive solar gain can lead to overheating within a space, but it can also be us ...
