Skylights
A skylight (sometimes called a rooflight) is a light-permitting structure or window, usually made of transparent or translucent glass, that forms all or part of the roof space of a building for daylighting and ventilation purposes. History Open skylights were used in Ancient Roman architecture, such as the oculus of the Pantheon. Glazed 'closed' skylights have been in use since the Industrial Revolution made advances in glass production manufacturing. Mass production units since the mid-20th century have brought skylights to many uses and contexts. Energy conservation has brought new motivation, design innovation, transmission options, and efficiency rating systems for skylights. Prior to the Industrial Revolution, it was Spain and France that probably had the leading technology in architectural glass. One of the earliest forms of glass skylight can be seen at the Burgos Cathedral in the Chapel of the Constable. Other early form of glass skylight can be seen at the Palace o ...

Daylighting
Daylighting is the practice of placing windows, skylights, other openings, and reflective surfaces so that sunlight (direct or indirect) can provide effective internal lighting. Particular attention is given to daylighting while designing a building when the aim is to maximize visual comfort or to reduce energy use. Energy savings can be achieved from the reduced use of artificial (electric) lighting or from passive solar heating. Artificial lighting energy use can be reduced by simply installing fewer electric lights where daylight is present or by automatically dimming/switching off electric lights in response to the presence of daylight – a process known as daylight harvesting. The amount of daylight received in an internal space can be analyzed by measuring illuminance on a grid or undertaking a daylight factor calculation. Computer programs such as Radiance allow an architect or engineer to quickly calculate benefits of a particular design. The human eye's respons ...

Halle Aux Blés (Paris)
The Halle aux blés (Wheats Exchange or Grains Exchange) was a circular building in central Paris used by grain traders built in 1763–67, with an open-air interior court that was capped by a wooden dome in 1783, then by an iron dome in 1811. In a major reconstruction in 1888–89 much of the structure was replaced and the building became the Bourse de commerce. The structure influenced the design of public buildings in Britain and the United States. History The city of Paris purchased the site of the former Hôtel de Soissons in 1755. The ''hôtel'' had been demolished and its materials sold, but the Medici column was left standing. On 23 November 1762 King Louis XV of France (1710–74) declared that a hall of grain and flour (halle aux blés et farines) would be built on the site. Construction of the hall began in 1763 following a design by Nicolas Le Camus de Mézières (1721–89), who supervised the work. The circular hall surrounding a circular courtyard was completed in ...

Oculus (architecture)
An oculus (; ) is a circular opening in the center of a dome or in a wall. Originating in antiquity, it is a feature of Byzantine and Neoclassical architecture. It is also known as an '' œil-de-boeuf'' from the French, or simply a "bull's-eye". History Classical The oculus was used by the Ancient Romans, one of the finest examples being that in the dome of the Pantheon. Open to the weather, it allows rain and air to enter and fall to the floor, where it is carried away through drains. Though the opening looks small, it actually has a diameter of , allowing it to light the building. Byzantine The oculus was widely used in the architecture of the Byzantine Empire. It was applied to buildings in Syria in the 5th and 6th centuries and again in the 10th century. In Constantinople's Myrelaion Church (c. 920), there are two oculi above the stringcourse on both lateral facades. Renaissance Early examples of the oculus in Renaissance architecture can be seen in Florence Cathedral, i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Retractable Roof
A retractable roof is a roof system designed to roll back the roof of a structure so that the interior of the facility is open to the outdoors. Retractable roofs are sometimes referred to as operable roofs or retractable skylights. The term operable skylight, while quite similar, refers to a skylight that opens on a hinge, rather than on a track. Retractable roofs are used in residences, restaurants and bars, swim centres, arenas and stadiums, and other facilities wishing to provide protection from the elements, as well as the option of having an open roof during favourable weather. History The United States Patent and Trademark Office (USPTO) records show that David S. Miller, founder of Rollamatic Retractable Roofs, filed in August 1963 for "a movable and remotely controllable roof section for houses and other types of buildings". Shapes and sizes While any shape is possible, common shapes are flat, ridge, hip-ridge, barrel and dome. A residence might incorporate one or mo ...

Roof Window
A roof window is an outward opening window that is incorporated as part of the design of a roof. Often confused with a skylight, a roof window differs in a few basic ways. A roof window is often a good option when there is a desire to allow both light and fresh air into the space. A roof window is also different from a tubular skylight, in that the light is not directed through any type of channel or tube in order to provide lighting for the interior of a building. This type of light tube design is often employed with buildings where the installation of a skylight or roof window is not practical. While a roof window is normally included in the original construction of the building, it is possible to add the design feature to an existing structure. As long as the framework and the slope of the roof allow for the inclusion of this type of window, it can be installed with relative ease. Many manufacturers offer prefabricated window inserts of this type that can be installed by a pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crown Glass (window)
Crown glass was an early type of window glass. In this process, glass was blown into a "crown" or hollow globe. This was then transferred from the blowpipe to a punty and then flattened by reheating and spinning out the bowl-shaped piece of glass (bullion) into a flat disk by centrifugal force, up to 5 or 6 feet (1.5 to 1.8 metres) in diameter. The glass was then cut to the size required. The thinnest glass was in a band at the edge of the disk, with the glass becoming thicker and more opaque toward the center. Known as a bullseye, the thicker center area around the pontil mark was used for less expensive windows. To fill large window spaces with the best glass, many small diamond shapes were cut from the edge of the disk, and then some might be halved into triangles. These were mounted in a lead lattice work and fitted into the window frame. Crown glass was one of the two most common processes for making window glass until the 19th century. The other was blown plate. Cro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Liverpool Central Library
Liverpool Central Library is the largest of the 22 libraries in Liverpool, England, situated in the centre of the city. History The library is located in several adjoining historic buildings on William Brown Street. Its first building was the William Brown Library and Museum building which was completed in 1860 to the designs of John Weightman Surveyor to Liverpool Corporation, (not to be confused with his near contemporary John Grey Weightman) and which it has always shared with the city's museum, now known as World Museum Liverpool. The library was then extended further to the right with the addition in 1879 of the Picton Reading Room and to the rear with the Hornby Library in 1906. All three of these are Grade II* listed buildings and are built in a classical style similar to other buildings on the street. Previous to the creation of this public library was England's first subscription library (1758-1942), latterly known as The Lyceum, Liverpool, but often referred to a ...

Münster
Münster (; nds, Mönster) is an independent city (''Kreisfreie Stadt'') in North Rhine-Westphalia, Germany. It is in the northern part of the state and is considered to be the cultural centre of the Westphalia region. It is also a state district capital. Münster was the location of the Anabaptist rebellion during the Protestant Reformation and the site of the signing of the Treaty of Westphalia ending the Thirty Years' War in 1648. Today it is known as the bicycle capital of Germany. Münster gained the status of a ''Großstadt'' (major city) with more than 100,000 inhabitants in 1915. , there are 300,000 people living in the city, with about 61,500 students, only some of whom are recorded in the official population statistics as having their primary residence in Münster. Münster is a part of the international Euregio region with more than 1,000,000 inhabitants ( Enschede, Hengelo, Gronau, Osnabrück). History Early history In 793, Charlemagne sent out Ludger as ...

Passive Cooling
Passive cooling is a building design approach that focuses on heat gain control and heat dissipation in a building in order to improve the indoor thermal comfort with low or no energy consumption. This approach works either by preventing heat from entering the interior (heat gain prevention) or by removing heat from the building (natural cooling). Natural cooling utilizes on-site energy, available from the natural environment, combined with the architectural design of building components (e.g. building envelope), rather than mechanical systems to dissipate heat. Therefore, natural cooling depends not only on the architectural design of the building but on how the site's natural resources are used as heat sinks (i.e. everything that absorbs or dissipates heat). Examples of on-site heat sinks are the upper atmosphere (night sky), the outdoor air (wind), and the earth/soil. Passive cooling is an important tool for design of buildings for climate change adaptationreducing dependenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
