“…Saidur et al (2009) reported that lighting in Malaysian office buildings represented approximately 19% of their total energy consumption. Lighting consumption depends on the purpose of the building and the use of daylight (Roshan and Barau, 2016). The energy consumption level depends on the power consumption of lighting systems and the operating periods.…”

“…Dengan pemanfaatan daylight ini dapat membantu mengurangi konsumsi energi sebesar 50% dan mengurangi pemakaian listrik sebesar 75% (US-IEA, 2008). Biasanya para arsitek/perancang yang memanfaatkan cahaya matahari yang masuk ke dalam bangunan bertujuan untuk meningkatkan kualitas visual dalam ruangan, kesehatan indera penglihatan, kenyamanan lingkungan dan meningkatkan produktivitas kinerja pengguna bangunan (Roshan & Barau, 2016). Selain itu juga, perancangan yang berbasis daylight atau pemanfaatan cahaya matahari pada siang hari juga akan memberikan dampak positif berupa kesehatan dan kesejahteraan, pengurangan energi dan estetika (Gambar 1) (Kelly Waskett et al, 2014).…”

The usage of daylight in a room or building during the day is a wide strategy for illuminating the room naturally without artificial lighting services so that it can reduce the energy consumption of building. In addition, the use of daylight aims to enhance the quality of spatial visualization, vision health, environmental comfort, and increase the performance of user productivity in the room. This research will discourse about the amount of light get into room to identify how much the daylight can be useful and captured by human sight’s perception through a radiance simulation camera which will be translated into realistic images. This simulation is experimental-based that include two phases, namely the configuration of alternative openings and draws light according to the perception of user’s vision, then the set of radiance simulation based on scripting to generate the realistic images. Based on this simulation, the amount of daylight is influenced by source, quantity, position, area of openings and the building orientation or building. The amount of light intensity also affects the visual comfort of users who have activities in the room. The result of this simulation is to identify the room that generates daylight area and non-daylight area to decrease the artificial lighting.Abstrak: Pemanfaatan pencahayaan alami (daylight) pada sebuah ruangan dan bangunan di siang hari merupakan salah satu strategi desain untuk menerangi ruangan secara alami tanpa bantuan cahaya buatan sehingga dapat mengurangi konsumsi energi pada bangunan. Selain itu juga, permanfaatan pencahayaan alami (daylight) bertujuan untuk meningkatkan kualitas visual dalam ruangan, kesehatan indera penglihatan, kenyamanan lingkungan dan meningkatkan produktivitas kinerja pengguna bangunan. Pada penelitian ini akan membahas mengenai besaran cahaya yang masuk ke dalam suatu ruangan untuk melihat seberapa besar pencahayaan alami yang masuk dan ditangkap dalam suatu persepsi indera penglihatan manusia melalui kamera simulasi radiance yang diwujudkan ke dalam foto realistik. Simulasi ini dilakukan dengan metode berbasis eksperimen mandiri (experimental-based) yang terdiri dua tahap, yaitu tahapan konfigurasi bentuk bukaan dan draw light berdasarkan persepsi indera penglihatan peneliti, kemudian dilanjutkan dengan simulasi radiance berbasis scripting untuk menghasilkan foto realistik. Berdasarkan hasil simulasi ini, besarnya cahaya alami yang masuk ke dalam ruangan dipengaruhi oleh beberapa faktor, yaitu sumber bukaan, jumlah bukaan, posisi bukaan, besaran bukaan, dan orientasi ruangan atau bangunan. Besarnya intensitas cahaya yang masuk juga akan mempengaruhi kenyamanan visual bagi pengguna yang beraktivitas dalam ruangan tersebut. Hasil dari penelitian ini untuk melihat konfigurasi mana yang menghasilkan sebagian area daylight dan area non-daylight yang cukup merata untuk menghindari bantuan cahaya buatan.

“…The prototype daylighting system is divided into two parts: light collection and light transmission. The novel optical design principles are divided into three categories: collection [33,100,[111][112][113][114][115], transmission [99] and collection with transmission [32,[38][39][40]44,47,49,52,56,96,103,106,116] (Table 8).…”

Daylighting systems make daylight illuminance possible, and the development of prototype daylighting systems can provide more efficient daylight illuminance. The purpose of this article is to review the development and performance of prototype daylighting systems in the last decade. The passive and active daylighting systems are listed separately and divided into the four categories by the presence and absence of hybrid. Each prototype daylighting system was evaluated in terms of cost and daylight performance and as well as their novel optical design. We evaluated the architecture and daylighting principles of each system by reviewing individual prototype daylighting systems. The cost of prototype systems still poses a challenge to development. How to use passive or active systems in different environments and whether or not electrical lighting assistance is needed is a controversial issue. However, active daylighting systems equipped with solar tracking systems are still mainstream. This research is a valuable resource for daylight researchers and newcomers. It is helpful to understand the advantages of various prototype daylighting systems and commercial daylighting systems that have been developed for many years; moreover, it is also possible to know the research directions suggested by the prototype daylighting systems. These will be of further use in developing innovative and better daylighting systems and designs.
