Abstract
Pemanfaatan cahaya matahari yang berlimpah di iklim tropis sebagai penerangan alami dapat membantu menghemat konsumsi energi pada bangunan rumah susun. Dalam menghadapi kondisi di tropis, dibutuhkan strategi penerangan menggunakan sistem shading dinamis untuk menghadapi perubahan kondisi lingkungan. Adapun performa shading dinamis sangat dipengaruhi oleh sistem kontrol dan teknik gerak yang diterapkan. Kombinasi gerak lipat dan rotasi pada folding shutter berpotensi menghasilkan pergerakan dan konfigurasi yang lebih bervariasi.
Penelitian ini bertujuan untuk mengevaluasi pengaruh folding shutter terhadap performa penerangan alami dalam konteks bangunan rumah susun. Eksperimen dengan bantuan simulasi Radiance digunakan sebagai metode penelitian. Variabel folding shutter yang meliputi konfigurasi operatif, sudut kisi-kisi shutter, dan jarak penempatan model diuji pada kondisi langit dan posisi matahari berbeda sebagai landasan untuk menyusun konsep model yang sesuai untuk iklim tropis.
Hasil eksperimen menunjukkan bahwa kontrol gerak lipat dapat membantu mengkontrol kuantitas cahaya, namun tidak berfungsi baik pada kondisi terkritis di iklim tropis. Adapun rotasi kisi-kisi shutter dapat mendifusikan serta mengkontrol pantulan cahaya lebih baik dibandingkan konfigurasi operatif. Konfigurasi tertutup dengan kisi-kisi shutter 0° dan 45° dapat mendistribusikan cahaya paling baik pada langit partly cloudy, dan kisi-kisi shutter 60° hingga 90° berfungsi baik pada langit overcast. Integrasi folding shutter dengan overhang 60 cm menghasilkan performa yang paling memenuhi kenyamanan visual, karena dapat mencegah paparan cahaya langsung sekaligus memantulkan cahaya ke dalam ruang.

The utilization of abundant sunlight in tropical climates as daylighting can help to save energy consumption in flats buildings. Based on the daylight conditions in tropics, there is a need for dynamic shading device applications in the façade to respond to environmental change. The dynamic shading device performance is greatly influenced by its control system and motion techniques. The combination of folding and rotation motion on the folding shutter has the potential to produce more varied movements and configurations.
This study aims to evaluate the effect of folding shutter on the daylighting performance in the context of flats buildings. Simulation using Radiance was conducted to test the sub-variables of folding shutter. The operative configurations, shutter’s rotation angles, and folding shutter’s placement were tested on different sky conditions and sun positions as a basis to make a model concept suitable for different conditions in tropics.
The results showed that the application of folding motion can help to control the daylight quantity, but does not function well in the most critical conditions in tropical climates. Whereas rotating the shutter can help to diffuse and control the direction of daylight reflection better than the operative configurations. A closed configuration with a shutter's angle of 0° and 45° can distribute daylight evenly in the partly cloudy sky, and shutter's angle of 60° to 90° performed the best in the overcast sky. The integration of the folding shutter with a 60 cm overhang produced the most stable performance that can meet the visual comfort because it can block the direct sunlight while reflecting enough daylight into the room.
