Lighting Building Interiors Requiring Lighting at Day Times by Conveying Daylight (original) (raw)

This paper presents summary information from literature review on daylighting in buildings. Almost one-quarter of the total electricity produced has been using for artificial lighting both commercial and state building interiors in developed and developing countries. The last century experienced some remarkable events, which showed us the importance of energy stability of the world's economic. After the first oil price shock in 1973, the new technologies focused on more efficient and renewable energy use. Recently, new issues in daylighting design have been raised in conjunction with new demands by the building industry. One of challenges is to bring usable daylight deep into the core of commercial buildings or in non-daylit areas. This may result in significant savings in energy consumption while creating an attractive visual environment. Hybrid solar lighting system is one of the most significant lighting alternatives.
