“…The occupancy control system could automatically turn on/off the electric lighting when the presence is detected (presence switches), or only switch off a manually turned on system when any movement is recognized (absence switches). The differences in savings between these two approaches could be high, especially in individual or small offices, as shown by Gentile et al (2012). These authors showed that using a presence (on/off) control system in small offices would yield higher energy use for lighting than a simple manual switch at the door with an absence detector (switch off), confirming results from previous research (Voss et al, 2006).…”

This paper presents a literature review about energy-efficient retrofit of electric lighting and daylighting systems in buildings. The review, which covers around 160 research articles, addresses the following themes: (1) retrofitting electric lighting in buildings, (2) electric lighting energy use and saving potential and (3) lighting retrofit strategies. The retrofit strategies covered in the review are: replacement of lamp, ballast or luminaire; use of task-ambient lighting design; improvement in maintenance; reduction of maintained illuminance levels; improvement in spectral quality of light sources; improvement in occupant behavior; use of control systems; and use of daylighting systems. The review indicates that existing general knowledge about lighting retrofit is currently very limited and that there is a significant lack of information concerning the actual energy performance of lighting systems installed in the existing building stock. The resulting key directions for future research highlights issues for which a better understanding is required for the spread and development of lighting retrofit.

“…The use of natural daylight in buildings significantly reduces the electric energy consumption by minimizing the use of artificial lighting during the day [8]. Previous research has shown that daylight utilization (replacement of electric light by daylight) can reduce the use of electric lighting by 50%-80% in office buildings [14]. Malaysian Minister of Energy, Communication and Multimedia, Tan Sri Datuk Leo Moggie said that one of the ways to save energy was through the efficient use of energy in building by the use of extensive day-lighting techniques that would reduce the amount electricity produced by lighting fixtures [15].…”

Abstract. The implementation of daylighting strategies in buildings is a common aspect in architecture. However, due to the availability of inexpensive electricity, natural lighting strategies became insignificant, and been overlooked by designers. With the current concern over rapid increment on electricity cost, many designers now try to revitalized daylighting strategies in buildings. This includes educational buildings. In Malaysian cases, it is a norm that universities; especially during lecture and studio sessions, used artificial lighting throughout the day. Definitely, this is not parallel with the "green" aim made by the Government in the Malaysian Plan. Therefore, this paper aims to explore the impact of daylight strategies for educational studios in universities, by maximising the penetration of natural daylight into the space towards creating a more green-conducive studio. The paper review literature about the types, criteria and benefits of daylight strategies. This paper also presented a pilot study that has been performed in one university in Perak, Malaysia, by selecting architectural studios as the main subject.

“…A system of illuminance sensors and electricity meters for the electric lights was installed to record the indoor and outdoor illuminance levels and the electricity consumption for the lighting system [23]. The data was collected by a logger, which was located in a service room adjoining the pig houses (Fig.…”
