Skylight Compass
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, when advances in glass manufacturing made them practical. Since the mid-20th century, mass production of skylights has brought them to many more uses and contexts. Energy conservation has brought new motivation for installing skylights, design innovations (including options in light transmission), and skylight efficiency ratings. Description Skylighting types include roof windows, unit skylights, tubular daylighting devices (TDDs), sloped glazing, and custom skylights. Uses include: * daylighting elements used to allow direct and/or indirect sunlight, via toplighting. * pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tubular Daylighting Device
Light tubes (also known as solar pipes, tubular skylights or sun tunnels) are structures that transmit or distribute natural or artificial light for the purpose of illumination and are examples of optical waveguides. In their application to daylighting, they are also often called tubular daylighting devices, sun pipes, sun scopes, or daylight pipes. They can be divided into two broad categories: hollow structures that contain the light with reflective surfaces; and transparent solids that contain the light by total internal reflection. Principles of nonimaging optics govern the flow of light through them. Types IR light tubes Manufacturing custom designed infrared light pipes, hollow waveguides and homogenizers is non-trivial. This is because these are tubes lined with a highly polished infrared reflective coating of gold, which can be applied thick enough to permit these tubes to be used in highly corrosive atmospheres. Carbon black can be applied to certain parts of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glass Brick
Glass brick, also known as glass block, is an architectural element made from glass. The appearance of glass blocks can vary in color, size, texture and form. Glass bricks provide visual obscuration while admitting light. The modern glass block was developed from pre-existing prism lighting principles in the early 1900s to provide natural light in manufacturing plants. Today glass blocks are used in walls, skylights, and sidewalk lights. Attributes Appearance The texture and color of glass blocks can vary in order to provide a range of transparency. Patterns can be pressed into either the inner void or the outside surface of the glass when it is cooling in order to provide differing effects. Glazes or inserts may also be added in order to create a desired private or decorative effect. Standards and grading Glass blocks in Europe are manufactured in accordance with the European Standard EN1052-2. The International Standard is ISO TC 160/SG1. The Standards allow for vari ...

Daylight Factor
In architecture, a daylight factor (DF) is the ratio of the light level inside a structure to the light level outside the structure. It is defined as: :''DF = (Ei / Eo) x 100%'' where, ''Ei'' = illuminance due to daylight at a point on the indoors working plane, ''Eo'' = simultaneous outdoor illuminance on a horizontal plane from an unobstructed hemisphere of overcast sky. To calculate ''Ei'', requires knowing the amount of outside light received inside of a building. Light can reach a room via through a glazed window, rooflight, or other aperture via three paths: * Direct light from a patch of sky visible at the point considered, known as the sky component (''SC''), * Light reflected from an exterior surface and then reaching the point considered, known as the externally reflected component (''ERC''), * Light entering through the window but reaching the point only after reflection from an internal surface, known as the internally reflected component (''IRC''). The sum of the thr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cupola
In architecture, a cupola () is a relatively small, usually dome-like structure on top of a building often crowning a larger roof or dome. Cupolas often serve as a roof lantern to admit light and air or as a lookout. The word derives, via Italian language, Italian, from lower Latin ''cupula'' (classical Latin ''cupella''), (Latin ''cupa''), indicating a vault resembling an upside-down cup. The cylindrical drum underneath a larger cupola is called a tholobate. Background The cupola evolved during the Renaissance from the older Oculus (architecture), oculus. Being weatherproof, the cupola was better suited to the wetter climates of northern Europe. The chhatri, seen in Architecture of India, Indian architecture, fits the definition of a cupola when it is used atop a larger structure. Cupolas often serve as a Bell tower, belfry, Belvedere (structure), belvedere, or roof lantern above a main roof. In other cases they may crown a spire, tower, or Turret (architecture), turret. B ...

Copolyester
A copolyester is a copolymer synthesized by modification of polyesters, which are combinations of diacids and diols. For example, by introducing other diacids, such as isophthalic acid (IPA), or other diols, such as cyclohexane dimethanol (CHDM) to the polyester polyethylene terephthalate (PET), the material becomes a copolyester due to its comonomer content.''Copolyester – A Versatile Choice for Medical Applications'' Thijs Jaarsma. 2004. Business Briefing: Medical Device Manufacturing & Technology. Copolyesters retain their strength, clarity, and other mechanical properties even when exposed to a variety of chemicals that typically affect other materials, such as polycarbonates. This, plus their versatility and flexibility, allows manufacturers to use them effectively in the design of both high-volume, low-cost parts as well as critical, more expensive component parts. Applications Copolyesters offer versatility to meet a wide variety of applications. Copolyester resins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polycarbonate
Polycarbonates (PC) are a group of thermoplastic polymers containing carbonate ester, carbonate groups in their chemical structures. Polycarbonates used in engineering are strong, toughness, tough materials, and some grades are optically transparent. They are easily worked, injection molding, molded, and thermoforming, thermoformed. Because of these properties, polycarbonates find many applications. Polycarbonates do not have a unique resin identification code, resin identification code (RIC) and are identified as "Other", 7 on the RIC list. Products made from polycarbonate can contain the precursor monomer bisphenol A (BPA). Structure Carbonate esters have planar OC(OC)2 cores, which confer rigidity. The unique O=C bond is short (1.173 Å in the depicted example), while the C-O bonds are more ether-like (the bond distances of 1.326 Å for the example depicted). Polycarbonates received their name because they are polymers containing carbonate ester, carbonate groups (−O−( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acrylate Polymer
An acrylate polymer (also known as acrylic or polyacrylate) is any of a group of polymers prepared from acrylate monomers. These plastics are noted for their transparency, resistance to breakage, and elasticity. Acrylate polymer is commonly used in cosmetics, such as nail polish, as an adhesive. History The first synthesis of acrylic polymer was reported by G. W. A. Kahlbaum in 1880. Acrylic elastomers Acrylic elastomer is a general term for a type of synthetic rubber whose primary component is acrylic acid alkylester ( ethyl or butyl ester). Acrylic elastomer possesses characteristics of heat and oil resistance, with the ability to withstand temperatures of 170–180 °C. It is used primarily for producing oil seals and packaging related to automobiles. Acrylic elastomer can generally be characterized as one of two types. "Old" types include ACM ( copolymer of acrylic acid ester and 2-chloroethyl vinyl ether) containing chlorine and ANM (copolymer of acrylic acid e ...

Solar Architecture
Solar energy is clean and renewable. Solar architecture is designing buildings to use the sun's heat and light to maximum advantage and minimum disadvantage, and especially refers to harnessing solar power. It is related to the fields of optics, thermics, electronics and materials science. Both PlusEnergy, active and Passive house, passive strategies are involved. The use of flexible thin-film photovoltaic modules provides fluid integration with steel Roofing material, roofing profiles, enhancing the building's design. Orienting a building to the sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air also constitute solar architecture. Improvements in solar architecture have been limited by the rigidity and weight of standard solar power panels. The continued development of photovoltaic (PV) thin film solar has provided a lightweight yet robust vehicle to harness solar energy to reduce a building's im ...

Prism Lighting
Prism lighting is the use of prisms to improve the distribution of light in a space. It is usually used to distribute daylight, and is a form of anidolic lighting. Prism lighting was popular from its introduction in the 1890s through to the 1930s, when cheap electric lights became commonplace and prism lighting became unfashionable. While mass production of prism lighting systems ended around 1940, the 2010s have seen a revival using new materials. How it works The human eye's response to light is non-linear: halving the light level does not halve the perceived brightness of a space, it makes it look only slightly dimmer. If light is redistributed from the brightest parts of a room to the dimmest, the room therefore appears brighter overall, and more space can be given a useful and comfortable level of illumination (see before and after images from an 1899 article, below). This can reduce the need for artificial lighting. Refraction and total internal reflection inside optica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
