Light as an architectural element
Light plays a central role in the design of a visual environment. The architecture, people and objects are all made visible by the lighting. Light influence our well being, the aesthetic effect and the mood of the room or area. It is the light that first enables ”what you see?”. Our perception of architecture will be influenced by light : Light defines zones and boundaries. 2. Light expands and accentuates rooms. 3. Light creates links and delineates one area from another
Necessity of lighting in designing spaces
Lighting has several functions, although to allow for artistic effect, no hard and fast rules can ever be applied. The functions of lighting include — Illumination: The simple ability to see what is occurring on . Any lighting design will be ineffective if the viewers cannot see the characters; unless this is the explicit intent. Revelation of form: Altering the perception of shapes on space, particularly three-dimensional elements. Focus: Directing the public attention to an area of the region or distracting them from another.
Lighting of an object or area so that it becomes brighter than its surroundings Functionality : The level of illumination required for a particular application depends greatly upon seeing the task involved and upon the surrounding conditions. Lighting objectives: Safety Performance( to allow work to be carried out in the night) Enhanced appearance to advertise To model a feature such as a statue To enable sporting events to be seen by spectators or to be televised in stage lighting
Planning & Process (Pre Analysis)
The basis for every lighting concept is an analysis of the project: — the tasks the lighting is expected to fulfill . –the conditions and special features of a space or work surface. A quantitative design concept can to a large extent follow the standards laid down for a specific task: –standards will dictate how much light is needed. –the degree of the glare limitation. –the source color and the color rendering. When it comes to qualitative planning: — It is necessary to gain as much information as possible about the environment to be illuminated — It is to be known that how it is used, who will use it and the style of architecture.
Planning & Process ( Post Analysis)
Preliminary light properties that lighting should possess. They may give no exact information about the choice of lamps or fixtures etc.• Further analysis provides illumination guidelines giving information about the individual forms of lighting…i.e. high levels will need high performance fixtures and lamps etc.• The challenge of a qualitative lighting design is to develop a design concept that combines the aesthetical and technical requirements of complex guidelines.• A concept that delivers the required performance with an equal level of technical expertise and the highest level of artistic clarity will produce the most convincing solution.
Concept of Architectural Lighting
Comprehensive lighting design requires: Consideration of the amount of functional light provided. The energy consumed. The aesthetic impact supplied by the lighting system. For example : • A)Public buildings, like surgical centre’s and sports facilities, are primarily concerned with providing the appropriate amount of light for the associated task. • B) Official buildings, like warehouses and office buildings, are primarily concerned with saving money through the energy efficiency of the lighting system. • C) Other buildings, like casinos and theatres, are primarily concerned with enhancing the appearance and emotional impact of architecture through lighting systems.
