Abstract

Bangunan rumah susun dengan unit hunian saling berdekatan satu sama lain menyebabkan bukaan hanya terletak pada satu sisi bangunan sehingga tingkat pencahayaan ruang buruk dan tidak merata. Disisi lain, fungsi rumah susun yang tidak hanya sebagai hunian namun juga sebagai tempat bekerja dan belajar memerlukan pencahayaan yang memenuhi standar aktivitas. Penggunaan lampu akan menambah konsumsi energi pada siang hari. Strategi peningkatan kinerja penerangan alami dapat dilakukan dengan merancang shading device tipe horizontal louvre yang dapat memasukkan cahaya ke dalam ruang sesuai dengan sudut altitude matahari iklim tropis lembab melalui geometri slat. Penelitian ini dilakukan untuk menganalisis peran geometri slat dan sudut putarnya terhadap kinerja pencahayaan alami di dalam ruang. Peran horizontal louvre terhadap kinerja penerangan alami dapat diketahui melalui strategi penelitian eksperimental menggunakan media mock-up unit hunian tipikal tipe 24 sebagai representasi unit rumah susun sederhana yang banyak dibangun di kota Surabaya.
Fokus penelitian ini adalah untuk mencari geometri slat horizontal louvre yang paling optimal diaplikasikan di iklim tropis lembab. Analisis daylight factor dilakukan untuk mengetahui prosentase intensitas cahaya matahari yang masuk ke dalam ruang. Pengukuran lapangan dilakukan pada akhir bulan Februari sampai awal bulan April dengan mock-up berada pada ketinggian lantai 3. Hasil penelitian ini menujukkan peran dalam meningkatkan kinerja pencahayaan didalam ruang sepanjang hari terdapat pada geometri slat 2 (dua) sudut putar 30° serta peran dalam menurunkan tingkat pencahayaan terdapat pada semua geometri sudut putar 0° dan 45° sepanjang hari. Terdapat 5 (lima) faktor yang mempengaruhi peran tersebut yaitu panjang bidang pantul, lebar slat, celah terbuka, bukaan slat dan luas penampang area pantul dengan faktor paling signifikan yaitu bukaan slat, kemiringan bidang pantul dan celah terbuka. Peran geometri slat berpotensi baik diaplikasikan pada iklim tropis lembab pada fix horizontal louvre menggunakan geometri slat 2 sudut 30° dan pada movable horizontal louvre menggunakan geometri slat 3 sudut 30° pada pagi dan sore, sudut 45° pada siang hari untuk meningkatkan pencahayaan dan sudut 30° pada siang hari untuk menurunkan pencahayaan yang berlebih.

Apartment buildings with residential units close to each other cause openings to only be located on one side of the building, so that the level of room lighting is poor and uneven. On the other hand, the function of flats, which serve not only as a residence but also as a place to work and study, requires lighting that meets activity standards. The use of lights will increase energy consumption during the day. The strategy to improve the performance of natural lighting can be done by designing a horizontal louvre-type shading device that can allow light to enter the room according to the angle of the sun's altitude in a humid tropical climate through slat geometry. This research was conducted to analyze the role of slat geometry and rotation angle on the performance of natural lighting in the room. The role of the horizontal louvre on the performance of natural lighting can be identified through an experimental research strategy using mock-up media for typical residential units of type 24 as a representation of simple flats that are widely built in the city of Surabaya.
The focus of this research is to find the most optimal louvre horizontal slat geometry applied in a humid tropical climate. A daylight factor analysis was carried out to determine the percentage of sunlight entering the room. Field measurements were carried out from the end of February to early April, with the mock-up at the 3rd floor height. The results of this study show that the role in improving indoor lighting performance throughout the day is in slat geometry 2 (two) with a 30° rotation angle, and the role in reducing lighting levels is found in all 0° and 45° turn geometries throughout the day. There are five factors that influence this role, namely the length of the reflecting plane, the width of the slat, the open gap, the slat opening, and the cross-sectional area of the reflection, with the most significant factors being the slat opening, the slope of the reflecting plane, and the open gap. The role of slat geometry has the potential to be well applied in humid tropical climates to fixed horizontal louvers using slat geometry at 2 angles of 30° and to movable horizontal louvres using slat geometry at 3 angles of 30° in the morning and evening, angles of 45° during the day to increase lighting, and angles of 30° during the day to reduce overexposure.
