Sawtooth Roof
A saw-tooth roof is a roof comprising a series of ridges with dual pitches either side. The steeper surfaces are glazed and face away from the equator to shield workers and machinery from direct sunlight. This kind of roof admits natural light into a deep plan building or factory. Advantages Before electric light substituted for daylight in the late 19th century, consideration of good daylight strategies was essential. The sawtooth roof, with its glass panels facing away from the equator, blocks the light and heat of direct sun exposure and provides uniform, natural light over a large area. Historically they were used in industrial and manufacturing buildings as the primary light source. Some architects think that sawtooth roofs look best when grouped in rows of three or more. Sawtooth roofs allow more efficient use of headroom and floor space. It is easy to install beams, columns and attractive elevations in the design of the roof. Sawtooth roofs provide for maximum headroom co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engines Branch
An engine or motor is a machine designed to convert one or more forms of energy into mechanical energy. Available energy sources include potential energy (e.g. energy of the Earth's gravitational field as exploited in hydroelectric power generation), heat energy (e.g. geothermal), chemical energy, electric potential and nuclear energy (from nuclear fission or nuclear fusion). Many of these processes generate heat as an intermediate energy form, so heat engines have special importance. Some natural processes, such as atmospheric convection cells convert environmental heat into motion (e.g. in the form of rising air currents). Mechanical energy is of particular importance in transportation, but also plays a role in many industrial processes such as cutting, grinding, crushing, and mixing. Mechanical heat engines convert heat into work via various thermodynamic processes. The internal combustion engine is perhaps the most common example of a mechanical heat engine, in which hea ...

Roof
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] |
Equator
The equator is a circle of latitude, about in circumference, that divides Earth into the Northern and Southern hemispheres. It is an imaginary line located at 0 degrees latitude, halfway between the North and South poles. The term can also be used for any other celestial body that is roughly spherical. In spatial (3D) geometry, as applied in astronomy, the equator of a rotating spheroid (such as a planet) is the parallel (circle of latitude) at which latitude is defined to be 0°. It is an imaginary line on the spheroid, equidistant from its poles, dividing it into northern and southern hemispheres. In other words, it is the intersection of the spheroid with the plane perpendicular to its axis of rotation and midway between its geographical poles. On and near the equator (on Earth), noontime sunlight appears almost directly overhead (no more than about 23° from the zenith) every day, year-round. Consequently, the equator has a rather stable daytime temperature throug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sunlight
Sunlight is a portion of the electromagnetic radiation given off by the Sun, in particular infrared, visible, and ultraviolet light. On Earth, sunlight is scattered and filtered through Earth's atmosphere, and is obvious as daylight when the Sun is above the horizon. When direct solar radiation is not blocked by clouds, it is experienced as sunshine, a combination of bright light and radiant heat. When blocked by clouds or reflected off other objects, sunlight is diffused. Sources estimate a global average of between 164 watts to 340 watts per square meter over a 24-hour day; this figure is estimated by NASA to be about a quarter of Earth's average total solar irradiance. The ultraviolet radiation in sunlight has both positive and negative health effects, as it is both a requisite for vitamin D3 synthesis and a mutagen. Sunlight takes about 8.3 minutes to reach Earth from the surface of the Sun. A photon starting at the center of the Sun and changing direction eve ...

Deep Plan
A deep plan building is a building in which the horizontal distance from the external wall is many times greater than the floor to floor height. Deep plan buildings make more efficient use of site area. They also cost less to build per unit floor area because of their smaller wall to floor area ratio. Deep plan buildings introduce complications for light and ventilation penetration that are relatively easily solved for single story buildings (for example using sawtooth roofs) but usually necessitate artificial lighting and air conditioning Air conditioning, often abbreviated as A/C or AC, is the process of removing heat from an enclosed space to achieve a more comfortable interior environment (sometimes referred to as 'comfort cooling') and in some cases also strictly controlling ... or ventilation if over one story.

Factory
A factory, manufacturing plant or a production plant is an industrial facility, often a complex consisting of several buildings filled with machinery, where workers manufacture items or operate machines which process each item into another. They are a critical part of modern economic production, with the majority of the world's goods being created or processed within factories. Factories arose with the introduction of machinery during the Industrial Revolution, when the capital and space requirements became too great for cottage industry or workshops. Early factories that contained small amounts of machinery, such as one or two spinning mules, and fewer than a dozen workers have been called "glorified workshops". Most modern factories have large warehouses or warehouse-like facilities that contain heavy equipment used for assembly line production. Large factories tend to be located with access to multiple modes of transportation, some having rail, highway and water loading ...

Titus Salt
Sir Titus Salt, 1st Baronet (20 September 1803 in Morley – 29 December 1876 in Lightcliffe), was a manufacturer, politician and philanthropist in Bradford, West Riding of Yorkshire, England, who is best known for having built Salt's Mill, a large textile mill, together with the attached village of Saltaire, West Yorkshire. Early life Titus Salt was born in 1803 to Daniel Salt, a drysalter and then a sheep farmer and Grace Smithies, daughter of Isaac Smithies, of The Manor House, Morley. His father sent him to a school in Batley, identified in some sources as Batley Grammar School, and then to another near Wakefield, named in some sources as Heath School. Between 1813 and 1819 the Salt family lived at The Manor House in Morley, before moving to Crofton, near Wakefield. Career After working for two years as a wool-stapler in Wakefield (between 1820 and 1822), Salt became his father's partner in the business of Daniel Salt and Son. The company used Russian ''Donskoi'' wool, whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saltaire
Saltaire is a Victorian era, Victorian model village in Shipley, West Yorkshire, Shipley, part of the City of Bradford Metropolitan District, in West Yorkshire, England. The Victorian era Salt's Mill and associated residential district located by the River Aire and Leeds and Liverpool Canal is a designated UNESCO World Heritage Site and an Anchor Point of the European Route of Industrial Heritage. History Saltaire was built in 1851 by Titus Salt, Sir Titus Salt, a leading industrialist in the Yorkshire woollen industry. The name of the village is a combination of the founder's surname and the name of the river. Salt moved his business (five separate mills) from Bradford to this site near Shipley, West Yorkshire, Shipley to arrange his workers and to site his large textile mill by the Leeds and Liverpool Canal and the railway. Salt employed the local architects Henry Francis Lockwood, Francis Lockwood and William Mawson. Similar, but considerably smaller, projects had also b ...

Natural Lighting
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 response to li ...

Central Telephone Exchange, Melbourne
The Central Telephone Exchange, Melbourne is a building in Central Melbourne, Australia, constructed between May 1907 and early 1909 by the Reinforced Concrete & Monier Pipe Construction Co. headed by engineer Sir John Monash, and designed by architect Samuel Charles Brittingham. The building includes an early example of a reinforced concrete saw-tooth roof. The building was commissioned by the Public Works Department of the Commonwealth of Australia to house the new telephone service, which came under the recently formed Post Master Geenral's Department following Federation of the Australian Colonies in 1901. the contract for construction was let in February 1908. The Lonsdale Street facade of the exchange was a two-storey Italianate style office block with stone facing with a long, narrow, three-storey building behind. This housed the exchange plant. The design employed reinforced concrete suspended floors supported on the load-bearing brick masonry walls and a centre row of rein ...
