Carnegie Free Library Of Beaver Falls
The Carnegie Free Library of Beaver Falls is a historic Carnegie library in the city of Beaver Falls, Pennsylvania, United States. Erected as Beaver County's first library building, it was financed by Andrew Carnegie and designed by a leading Pittsburgh architect in grand architectural style that helped to redefine the image of the typical Carnegie library. Numerous community organizations have used its space, which remains in continued use as a library, and it has been named a historic site. History In late 1883, community leaders formed a private library association, and a related lecture series was held to raise money through ticket sales. Small enough that it could fit in a grocery store, the resulting collection experienced enough use that it could be seen to be too small for the community's needs,'' National Register of Historic Places Inventory/Nomination: Carnegie Free Library, Beaver Falls'.

Pennsylvania Route 18
Pennsylvania Route 18 (PA 18) is a major north–south highway in Western Pennsylvania whose southern terminus is at West Virginia Route 69 (WV 69) at the state line in Greene County near the village of Garrison, while the northern terminus is at PA 5 in Lake City. At a length of , PA 18 is the only state route in Pennsylvania — north–south ''or'' east–west — to traverse the entire state. It also has the distinction of being the longest state route in Pennsylvania. Route description Greene County Traveling northward from West Virginia Route 69 at the West Virginia state line, Route 18 winds through rural Greene County, passing through the villages of Garrison, New Freeport, Nettle Hill, White Cottage, Woodruff, and Holbrook, before making its first junction with another state highway, PA Route 21, just west of the village of Rogersville and over from the state line. Here the two routes overlap for nearly , winding east-northeast through Rogersville ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Floor Plan
In architecture and building engineering, a floor plan is a technical drawing to scale, showing a view from above, of the relationships between rooms, spaces, traffic patterns, and other physical features at one level of a structure. Dimensions are usually drawn between the walls to specify room sizes and wall lengths. Floor plans may also include details of fixtures like sinks, water heaters, furnaces, etc. Floor plans may include notes for construction to specify finishes, construction methods, or symbols for electrical items. It is also called a ''plan'' which is a measured plane typically projected at the floor height of , as opposed to an ''elevation'' which is a measured plane projected from the side of a building, along its height, or a section or ''cross section'' where a building is cut along an axis to reveal the interior structure. Overview Similar to a map, the orientation of the view is downward from above, but unlike a conventional map, a plan is drawn at a part ...

Skylight
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 Roman architecture, Ancient Roman architecture, such as the Oculus (architecture), oculus of the Pantheon, Rome, 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 e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dormer
A dormer is a roofed structure, often containing a window, that projects vertically beyond the plane of a pitched roof. A dormer window (also called ''dormer'') is a form of roof window. Dormers are commonly used to increase the usable space in a loft and to create window openings in a roof plane. A dormer is often one of the primary elements of a loft conversion. As a prominent element of many buildings, different types of dormer have evolved to complement different styles of architecture. When the structure appears on the spires of churches and cathedrals, it is usually referred to as a ''lucarne''. History The word ''dormer'' is derived from the Middle French , meaning "sleeping room", as dormer windows often provided light and space to attic-level bedrooms. One of the earliest uses of dormers was in the form of lucarnes, slender dormers which provided ventilation to the spires of English Gothic churches and cathedrals. An early example are the lucarnes of the spire of C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heat Transfer
Heat transfer is a discipline of thermal engineering that concerns the generation, use, conversion, and exchange of thermal energy (heat) between physical systems. Heat transfer is classified into various mechanisms, such as thermal conduction, Convection (heat transfer), thermal convection, thermal radiation, and transfer of energy by phase changes. Engineers also consider the transfer of mass of differing chemical species (mass transfer in the form of advection), either cold or hot, to achieve heat transfer. While these mechanisms have distinct characteristics, they often occur simultaneously in the same system. Heat conduction, also called diffusion, is the direct microscopic exchanges of kinetic energy of particles (such as molecules) or quasiparticles (such as lattice waves) through the boundary between two systems. When an object is at a different temperature from another body or its surroundings, heat flows so that the body and the surroundings reach the same temperature, ...

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 ...

Stained Glass
Stained glass is coloured glass as a material or works created from it. Throughout its thousand-year history, the term has been applied almost exclusively to the windows of churches and other significant religious buildings. Although traditionally made in flat panels and used as windows, the creations of modern stained glass artists also include three-dimensional structures and sculpture. Modern vernacular usage has often extended the term "stained glass" to include domestic lead light and ''objets d'art'' created from foil glasswork exemplified in the famous lamps of Louis Comfort Tiffany. As a material ''stained glass'' is glass that has been coloured by adding metallic salts during its manufacture, and usually then further decorating it in various ways. The coloured glass is crafted into ''stained glass windows'' in which small pieces of glass are arranged to form patterns or pictures, held together (traditionally) by strips of lead and supported by a rigid frame.

Fanlight
A fanlight is a form of lunette window, often semicircular or semi-elliptical in shape, with glazing bars or tracery sets radiating out like an open fan. It is placed over another window or a doorway, and is sometimes hinged to a transom. The bars in the fixed glazed window spread out in the manner of a sunburst. It is also called a "sunburst light".

Bay (architecture)
In architecture, a bay is the space between architectural elements, or a recess or compartment. The term ''bay'' comes from Old French ''baie'', meaning an opening or hole."Bay" ''Online Etymology Dictionary''. http://www.etymonline.com/index.php?allowed_in_frame=0&search=bay&searchmode=none accessed 3/10/2014 __NOTOC__ Examples # The spaces between posts, columns, or buttresses in the length of a building, the division in the widths being called aisles. This meaning also applies to overhead vaults (between ribs), in a building using a vaulted structural system. For example, the Gothic architecture period's Chartres Cathedral has a nave (main interior space) that is '' "seven bays long." '' Similarly in timber framing a bay is the space between posts in the transverse direction of the building and aisles run longitudinally."Bay", n.3. def. 1-6 and "Bay", n.5 def 2.

Granite
Granite () is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is nearly alway ...

Foundation (engineering)
In engineering, a foundation is the element of a structure which connects it to the ground, transferring loads from the structure to the ground. Foundations are generally considered either shallow or deep. Foundation engineering is the application of soil mechanics and rock mechanics (geotechnical engineering) in the design of foundation elements of structures. Purpose Foundations provide the structure's stability from the ground: * To distribute the weight of the structure over a large area in order to avoid overloading the underlying soil (possibly causing unequal settlement). * To anchor the structure against natural forces including earthquakes, floods, droughts, frost heaves, tornadoes and wind. * To provide a level surface for construction. * To anchor the structure deeply into the ground, increasing its stability and preventing overloading. * To prevent lateral movements of the supported structure (in some cases). Requirements of a good foundation The design and the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palladian Architecture
Palladian architecture is a European architectural style derived from the work of the Venetian architect Andrea Palladio (1508–1580). What is today recognised as Palladian architecture evolved from his concepts of symmetry, perspective and the principles of formal classical architecture from ancient Greek and Roman traditions. In the 17th and 18th centuries, Palladio's interpretation of this classical architecture developed into the style known as Palladianism. Palladianism emerged in England in the early 17th century, led by Inigo Jones, whose Queen's House at Greenwich has been described as the first English Palladian building. Its development faltered at the onset of the English Civil War. After the Stuart Restoration, the architectural landscape was dominated by the more flamboyant English Baroque. Palladianism returned to fashion after a reaction against the Baroque in the early 18th century, fuelled by the publication of a number of architectural books, including Pall ...
