“…The method of transmitting daylight by the fibre optic cable was studied by several researchers based on the system approach. The fibre optic photocell represents one of the approaches used by Hayman [55], where the experiment of the study used a fibre optic photocell consisting of a cosine corrected detector fixed at the end of the cable. The experiment results in high light losses in the cable but the absolute magnitude is small.…”

As a developing country, Malaysia requires innovation to keep abreast of the rapid growth of technology to meet the highly demanding energy consumption. The application of daylighting systems especially by fibre optics is very limited, due to the absence of relevant knowledge and the lack of understanding of the system requirements and potentials, particularly the technology of illuminating enclosed spaces which are totally surrounded by internal walls (opaque). Thus, the aim of this literature review is to shed light on this new approach and to help the building technologists activate its application in building interiors. This paper presents and summarises the important technical issues that enhance the adoption of this technique for the Malaysian built environment.

“…Ghisi and Tinker 71 pointed out that the use of optical fibres in rooms with narrow width and large area has a higher potential for energy savings. It is observed that (i) light loss is a function of the transmission coefficient of the fibre-optic material and the length of the fibre 72,73 and (ii) the use of fibre optics is limited by the complexity of the tracking mechanisms required to concentrate solar energy and their cost, 84 (iii) these fibres have the advantage of easy integration into buildings due to small size and flexibility, (iv) heat output from the fibres is very little unlike other systems (v) light should be highly concentrated before entering fibre since the fibre acceptance aperture is small.…”

In a dense urban environment, sky obstruction caused by high rise buildings causes minimal daylighting for interiors on lower floors and in deep interior spaces. Innovative daylighting systems can be used to enhance daylighting indoors using available sunlight. This paper presents an overview of recent developments of innovative daylighting systems. The daylighting systems, which are classified as light guiding, light transport, light diffracting, hybrid and integrated systems, have been reviewed and a comparison has been made with respect to ease of integration, durability, maintenance, availability, efficiency, light output and transportation. Suitability of climate has been identified with respect to each daylighting system. Recent research and development involves hybrid and integrated systems which have the advantage of providing lighting irrespective of external sky conditions. The advantages and disadvantages of each system are summarized. Compared to active systems, passive systems are environmentally friendly and their efficiencies are also higher. It is inferred that each system has its own unique principle of light transmittance and is suitable for certain climates. More research is required on developing daylighting systems which are environment friendly, less energy intensive, cost-effective and having ease of integration.
