Lantern (architecture)
A roof lantern is a daylighting architectural element. Architectural lanterns are part of a larger roof and provide natural light into the space or room below. In contemporary use it is an architectural skylight structure. A lantern roof will generally mean just the roof of a lantern structure in the West, but has a special meaning in Indian architecture (mostly Buddhist, and stretching into Central Asia and eastern China), where it means a dome-like roof raised by sets of four straight beams placed above each other, "arranged in diminishing squares", and rotated with each set. Normally such a "lantern" is enclosed and provides no light at all. The term ''roof top lantern'' is sometimes used to describe the lamps on roofs of taxis in Japan, designed to reflect the cultural heritage of Japanese paper lanterns. History The glazed lantern was developed during the Middle Ages. Roof lanterns of masonry and glass were used in Renaissance architecture, such as in principal cathedr ...

Victorian Era
In the history of the United Kingdom and the British Empire, the Victorian era was the period of Queen Victoria's reign, from 20 June 1837 until her death on 22 January 1901. The era followed the Georgian period and preceded the Edwardian period, and its later half overlaps with the first part of the '' Belle Époque'' era of Continental Europe. There was a strong religious drive for higher moral standards led by the nonconformist churches, such as the Methodists and the evangelical wing of the established Church of England. Ideologically, the Victorian era witnessed resistance to the rationalism that defined the Georgian period, and an increasing turn towards romanticism and even mysticism in religion, social values, and arts. This era saw a staggering amount of technological innovations that proved key to Britain's power and prosperity. Doctors started moving away from tradition and mysticism towards a science-based approach; medicine advanced thanks to the adoption ...

Windows
Windows is a group of several proprietary graphical operating system families developed and marketed by Microsoft. Each family caters to a certain sector of the computing industry. For example, Windows NT for consumers, Windows Server for servers, and Windows IoT for embedded systems. Defunct Windows families include Windows 9x, Windows Mobile, and Windows Phone. The first version of Windows was released on November 20, 1985, as a graphical operating system shell for MS-DOS in response to the growing interest in graphical user interfaces (GUIs). Windows is the most popular desktop operating system in the world, with 75% market share , according to StatCounter. However, Windows is not the most used operating system when including both mobile and desktop OSes, due to Android's massive growth. , the most recent version of Windows is Windows 11 for consumer PCs and tablets, Windows 11 Enterprise for corporations, and Windows Server 2022 for servers.

Roofs
A roof ( : roofs or rooves) is the top covering of a building, including all materials and constructions necessary to support it on the walls of the building or on uprights, providing protection against rain, snow, sunlight, extremes of temperature, and wind. A roof is part of the building envelope. The characteristics of a roof are dependent upon the purpose of the building that it covers, the available roofing materials and the local traditions of construction and wider concepts of architectural design and practice, and may also be governed by local or national legislation. In most countries, a roof protects primarily against rain. A verandah may be roofed with material that protects against sunlight but admits the other elements. The roof of a garden conservatory protects plants from cold, wind, and rain, but admits light. A roof may also provide additional living space, for example, a roof garden. Etymology Old English 'roof, ceiling, top, summit; heaven, sky', also f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Energy-saving Lighting
Various governments have passed regulations to phase out manufacturing or importation of incandescent light bulbs for general lighting in favor of more energy- efficient alternatives. The regulations are generally based on efficiency, rather than use of incandescent technology. However, it is not unlawful to continue to buy or sell existing bulbs, which are unregulated. Brazil and Venezuela started the phase-out in 2005, and the European Union, Switzerland, and Australia began to phase them out in 2009. Likewise, other nations are implementing new energy standards or have scheduled phase-outs: Argentina, and Russia in 2012, and Canada,"Canada to ban incandescent light bulbs by 2012" |
Passive Daylighting

Daylighting
Daylighting is the practice of placing windows, skylights, other openings, and Reflective surfaces (climate engineering), 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 Dimmer, 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 (software), Radiance allow an architect or engineer to quickly cal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cupola
In architecture, a cupola () is a relatively small, most often dome-like, tall structure on top of a building. Often used to provide a lookout or to admit light and air, it usually crowns a larger roof or dome. The word derives, via Italian, from lower Latin ''cupula'' (classical Latin ''cupella''), (Latin ''cupa''), indicating a vault resembling an upside-down cup. Background The cupola evolved during the Renaissance from the older oculus. Being weatherproof, the cupola was better suited to the wetter climates of northern Europe. The chhatri, seen in Indian architecture, fits the definition of a cupola when it is used atop a larger structure. Cupolas often serve as a belfry, belvedere, or roof lantern above a main roof. In other cases they may crown a spire, tower, or turret. Barns often have cupolas for ventilation. Cupolas can also appear as small buildings in their own right. The square, dome-like segment of a North American railroad train caboose that contains the seco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conservatory (greenhouse)
A conservatory is a building or room having glass or other transparent roofing and walls used as a greenhouse or a sunroom. Usually it refers to a space attached to a conventional building such as a house, especially in the United Kingdom. Elsewhere, especially in America, it can often refer to a large free-standing glass-walled building in a botanic garden or park, sometimes also called a palm house if tall enough for trees. Municipal conservatories became popular in the early 19th century. Description Many cities, especially those in cold climates and with large European populations, have built municipal conservatories to display tropical plants and hold flower displays. This type of conservatory was popular in the early nineteenth century, and by the end of the century people were also giving them a social use (e.g., tea parties). Conservatory architecture varies from typical Victorian glasshouses to modern styles, such as geodesic domes. Many were large and impressive ...

Chhatri
''Chhatri'' are elevated, dome-shaped pavilions used as an element in Indo-Islamic architecture and Indian architecture. Originating as a canopy above tombs, they serve as decorative elements. The earliest example of chhatri being used in the Indian Subcontinent were found in the Shrine of Ibrahim in Bhadreswar, constructed between 1159 and 1175 AD. Chhatri are found particularly within Mughal architecture. The most notable surviving examples today are to be found at Humayun's Tomb in Delhi and the Taj Mahal in Agra. The Berar Sultanate in the Deccan added chhatris on buildings in its various capitals. Chhatri have also been used in Rajasthan and other parts of the Indian Subcontinent by both Muslim and Hindu rulers. Its origins are, however, Indo-Islamic. While chhatri in Shekhawati may consist of a simple structure of one dome raised by four pillars to a building containing many domes and a basement with several rooms. In some places, the interior of the chhatri is painted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insulated Glazing
Insulating glass (IG) consists of two or more glass window panes separated by a space to reduce heat transfer across a part of the building envelope. A window with insulating glass is commonly known as double glazing or a double-paned window, triple glazing or a triple-paned window, or quadruple glazing or a quadruple-paned window, depending upon how many panes of glass are used in its construction. Insulating glass units (IGUs) are typically manufactured with glass in thicknesses from 3 to 10 mm (1/8" to 3/8"). Thicker glass is used in special applications. Laminated or tempered glass may also be used as part of the construction. Most units are produced with the same thickness of glass on both panes but special applications such as acoustic attenuation or security may require different thicknesses of glass to be incorporated in a unit. The space in between the panes provides the bulk of the insulation effect and may be filled with air, but argon is often used as it ...
