“…The characteristics for Malaysia's climate allowed and enable the usage of solar resources to be utilized via daylighting system. Thus, the collection of daylight data is crucial to be considered in designing buildings using daylight [1,12]. The quality and quantity of external illuminance in a particular location is always considered primarily in many previous studies [12][13][14][15][16][17][18].…”

“…The consumption of electric lighting is a concern by the level of usage in residential buildings at 25.3%, shopping complexes 51.9% and offices 42.5% [9][10][11]. Thus, increasing the use of natural daylighting for lighting purposes in buildings can offer major savings in energy consumption, improves internal environment, and also replaces electric lamps during daytime [10,12,13].…”

“…The design of light pipe structure plays an important role in daylighting system as the reflected light that emitted from the light pipe to the diffuser can transform a dark space into space that is bright and full of natural light [14][15][16]. The recommended light intensity for offices, classes, libraries, show rooms and laboratories is 200 ~ 500 lux [12,13,17].…”

Daylighting design strategy is important in order to have adequate lighting source in a room and necessary to decrease energy consumption for artificial lighting. Passive daylighting system utilizes daylight by collecting, reflecting and diffusing the natural light throughout a given area. The purpose for this study is to monitor, compare and analyse an optimum light pipe system design that can scatter daylight into a room based on three case studies. Lighting analysis was conducted using Autodesk 3ds Max Design software throughout the project based on the actual geographical parameters of Universiti Malaysia Perlis, Malaysia and also using the real sun azimuth on working hours. The results were compared according to the respective designs in order to observe the maximum internal illuminance and the average internal illuminance. The results show that the straight geometry with low aspect ratio produces the highest interior light intensity among other light pipe systems and the average internal illuminance values in the room was able to reach the minimum requirement of a small room which is 200 – 500 lux.

“…To address designing and decision-making issues for usage of light pipes daylight penetration, factor (DPF) was developed and introduced to supplement to well-adopted daylight factor (DF) [82][83][84]. Recent experimental studies conducted worldwide, addressing the comparison of different light pipe configuration, lead to a conclusion on energy saving potential in many specific local solar climates [85][86][87][88][89][90][91][92][93][94][95].…”

This paper is a literature study of daylight transport systems aiming at selecting the most appropriate ones for application at high latitudes. It is limited to the systems that transport light at a long distance from the façade and distribute it either in the building core or at a rear place in a room adjacent to the façade. The literature is spanning from the 80s' to the present. It covers the theoretical background and development of the systems from their infancy, through technical development of the design elements and to the adaptation of the systems to different climatic conditions. Since the most literature comes from equatorial and tropical climate, a short contextualization with high latitudes climate is included. Findings are systematized and presented in tables for easier comparison of efficiency, visual comfort, design efficacy, maintenance need, cost and/or availability on the market, and energy-saving potential in different climates. Conclusions confirm that the daylight condition at the location is the main prerequisite when deciding on the type of collector while the building structure and room functionality are the basis for choosing the type of the transport element. Finally, the distribution element showed to be the key factor when discussing applicability in a functional space where the final success depends on human acceptance. This paper can be useful to get an overview of performance characteristics and application preferences of different daylight transport systems or just their components in daylight conditions at high latitudes.

“…Research on indoor natural lighting systems has been conducted using various methods. Analysis has also been carried out regarding the study of the potential for natural light to be used in buildings in Malaysia using light pipe systems (Kadir et al, 2016). The research was carried out by looking at the response of the light pipe system to differences in sky conditions.…”

Energy consumption continues to increase and is predicted to increase by up to 30 percent by 2040. Therefore, systematic efforts are needed to reduce energy use, including using natural lighting in lighting systems inside buildings. The object of this study is the library room in the Electrical Engineering Department building, Universitas Andalas, Indonesia, to calculate the potential for energy savings with a lighting automation strategy with dimming control. Measurement of natural light level at three work nodes has been determined for one week as reference data. The shortage of artificial light required, and the electrical energy consumed is calculated by referring to the minimum standards for room lighting intensity. On the basis of each lamp's working hours and power, the potential for energy savings in the lighting system of the object can be determined. This study found that the potential for saving energy consumption for one week at three different nodes was 32.3, 64.2, and 82.8 percent. This study concludes that the maximum value reached 893 lux on Tuesday at 13:00 at node C, and the lowest was 3 lux on Saturday at 15:00 WIB at node A. Node C had an average light intensity of 402.298 lux, and node B had an average of 206.765 lux during the week. In contrast, node A has the lowest lux average, with 87,711 lux in one measurement week. Also, with the combination of natural and artificial light sources with dimming control strategies, the voltage values given to each lamp range from 0 to 180 VAC. Potential savings in energy consumption by combining natural and artificial light with dimming control strategies in the library room with three different nodes (A, B, C) are 32.3, 64.2, and 82.8 percent.
