“…However, from a commercial point of view, if the main requirement is to have a collector which can be obtained at a competitive price, then the conic Cassegrain collector will be the better solution. The conic Cassegrain collector reduces costs while still providing good collection efficiency [36,44].…”

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.

Empirical Evaluation of the Effect of Heat Gain from Fiber Optic Daylighting System on Tropical Building Interiors

et al. 2014

A fiber optic daylighting system is an evolving technology for transporting illumination from sunlight into building interiors. This system is a solution developed by daylighting designers to reduce operational costs and enhance comfort. As an innovative technology, fiber optic daylighting systems can illuminate building interiors efficiently compared with other daylighting strategies. However, as a transmission medium in daylighting systems, optical fibers require uniform light distribution in sunlight concentration, which could generate heat. Therefore, this study aims to investigate the effect of heat buildup produced by end-emitting fiber optic daylighting systems in tropical buildings. The applied method adopts a new fiber optic daylighting system technology from Sweden called Parans SP3, with a 10 m cable to be tested in an actual room size under the Malaysian climatic environment, particularly within the vicinity of the main campus of the Universiti Sains Malaysia. Results show that the system generated a temperature of 1.3 °C under average conditions through fiber optic diffusers and increases indoor temperature by 0.8 °C in a 60 m3 room. According to the results, applying fiber optic daylighting systems, as renewable energy sources, generates extra heat gain in building interiors in the tropics.

The Behavior of Internal Humidity From Fibre Optic Daylighting System Application

et al. 2015

Electrical lighting consumed 13% to 43% from overall energy which considered as second major usage of electrical energy in a building. Fibre optic daylighting is a potential approach for the remote source daylighting which is able to minimize the usage of electrical light if the minimum recommended standard of human comfort is achieved. Since the internal humidity also plays an important role in human comfort, the objectives of this research are to investigate the effects of the application inside building for humidity. This research assessed the potential of fibre optic daylighting for interior illumination using 4 m x 5 m x 2.8 (H-Ceiling) spaces through empirical data collection in an actual environment. The data were collected for every 5 minutes from 8:00 AM to 6:00 PM on the 17th May 2013 until the 2nd June 2013 using 4 computer-linked sensors to record humidity for both external and internal building. The comparison approach was selected in analyzing the data collected with the observation. . It is shown that the fibre optic daylighting system has no significant effect in relative humidity even possibly increases the internal room temperature by 2oC.
