ROOF LIGHTS

Post 100  by Gautam Shah ➔
 .
In its most common usage a roof or skylight describes an entity that sits atop a roof, high up in the wall or ceilings. These were meant for illumination and ventilation. Such openings have been of minuscule holes to very large gaps, often covering the room’s entire surface.



Roof light openings have been used in buildings for ages. But in early periods such gaps were open or covered with a fabric, lattice, wooden slats or louvres. It was with the use of glass that such gaps became fixed-transparent panes. Roof-light openings with wood frames required frequent repair-replacements and were not weather tight. During Victorian Era, with metal construction, skylights became very popular. Virtually every urban row house of the late 19th and early 20th C relied on a metal-framed skylight to illuminate the enclosed stairwell.

Roof window or day lighting is a flat or sloped opening as part of the roof, used for day lighting. Skylights are flat, shaped by the struc…

TOWER STRUCTURES

by Gautam Shah ➔

TOWERS are tall structures serving many different purposes. Towers are generally square or circular, and only occasionally multi-cornered. Towers have size tapering or narrowing to the top. A tower could be a solid mass like column, or hallowed out mass with a with spirally wound access stairs. Towers, whether a Column or Hollowed structures are mostly independent entities except in case of mosque towers for Azan (calling Muslim faithful for prayers).


Column towers signify a place or location due to the visibility from a great distance. Column towers are commemorative structures such as Ashok Stambha, milestone, survey locations pillars, boundary junction markers, Dwaja Stambha (Flag mast or tower).

'The obelisks,' says Ebers, 'were sacred to Ra, the sun.' It has been remarked that sometimes they were entirely gilt, that the apex was at other times covered with gilded bronze, and some at least appear to have carried spheres or discs, also of gilded metal…

SPACE PERCEPTION

by Gautam Shah >>Space is a vast expanse where Objects are space-positioned and Happenings gettime-scheduled. The objects and happenings, both continuously shift in position and schedule, but relative to each other. In this sense a space is a matrix of relationships. Space Perception is becoming aware of such a matrix.


The matrix of relationships manifests in the environment, where both the space and perceiver exist. Perception of space is also becoming aware of the environment, organisms and objects. The causative factors of the environment are seen as a change in the space. We perceive the changes through the sensorial nodes of the body.
All sensorial perceptions involve signals in the nervous system, which in turn result from physical or chemical stimulation of the sense organs. For a given event thousands of nerve impulses are generated and conducted along many different nerve fibres, but at slightly different times to the central nervous system. They form a pattern of input t…

SPATIAL DEFINITIONS

by Gautam Shah   >>A very vast space is perceived only through its markings. A ‘sunset, a valley or seashores’ are Markings of a space. These are evident through physical elements like: edges, banks, thresholds, slopes, plains or fences and environmental effects thereon. Markings in a very vast space indicate the extent of the space, but do not define it. Perception of markings is subjective and circumstantial, because the reach varies with perceiver’s capacity, needs and environmental conditions.

Spaces, however, are more definitively perceived through the Bounding elements. The bounding elements offer an exclusivity through a change-line, such as a drop in terrain, contours, variation colour or texture, illuminated or shaded objects, etc. Bounding elements restrict limitless experience of the space and environmental effects. The bounding elements indicate the nature of ownership (dominion) and structure of administration, and so the purpose of the space. Bounding elements are p…
