Abstract

The current interior lighting design concept has adopted the concept of mean room surface exitance (MRSE), which is important to the emphasize on the perceptual brightness or ambient illuminance of the space as a whole, instead of using the workplane illuminance parameter, which is often inefficient in terms of energy use. An application of lighting design that requires specific attention is hotel guestrooms, which shall provide comfort and aesthetics, and shall accomodate various visual activities of the occupants. The purpose of this study is to apply the concept of MRSE-based electric lighting design to the case of a premium hotel guestroom, to improve visual comfort and energy efficiency. The implemented method is determining the target/ambient illuminance ratio (TAIR) for each object in the room, determining the amount of luminous flux that must be provided, and determining the MRSE and TAIR values from the lighting simulations using DIALux evo software in various scenarios, namely in the (1) bathroom, (2) main (bed)room for reading and writing, (3) main room for sleeping, and (4) main room for reading prior to sleeping. Initial design calculation indicates MRSE values of 100 lm/m2 in Scenario 1, 100 lm/m2 in Scenario 2, 30 lm/m2 in Scenario 3, and 30 lm/m2 in Scenario 4. The simulation results show that the MRSE value from the modeling is found to be 147.5 lm/m2 1, 109.5 lm/m2, 30.2 lm/m2, and 32.5 lm/m2 in each scenario, in relatively close agreement with the initial design calculations, satisying the visual comfort target and increasing the efficiency of electric lighting energy use. This study contribute in demonstrating the interior lighting design concept that can be correlated with the perceptual brightness of the occupants, as well as with the energy efficiency improvement.

Abstract

Pencahayaan alami siang hari (PASH) ialah unsur krusial untuk dipertimbangkan pada desain bangunan karena dua manfaat besar yaitu efisiensi energi dan peningkatan kinerja dan kesehatan pengguna. Di Indonesia hanya terdapat satu regulasi yang mengatur tentang PASH dalam bangunan, yaitu Standar Nasional Indonesia (SNI) SNI 03-2396-2001. Selain belum pernah diperbarui kembali sejak dipublikasikan, terdapat sejumlah persoalan dalam SNI 03-2396-2001, antara lain penggunaan model langit seragam yang tidak lagi relevan serta adanya kesalahan nilai-nilai faktor langit (FL) pada tabel yang dicantumkan standar tersebut. Untuk itu, penelitian ini mengusulkan penggunaan model langit berawan standar CIE yang masih berlaku saat ini, serta mengamati nilai galat dari FL pada berbagai kasus uji dalam SNI 03-2396-2001 dan kasus uji 5.11 dalam dokumen CIE 171:2006. Metode analitik digunakan untuk menghitung nilai FL dan mengetahui nilai galat untuk model langit seragam pada SNI 03-2396-2001 terhadap langit berawan standar CIE. Hasil yang didapat menunjukkan perbedaan nilai FL yang signifikan untuk kasus H/D < 1,0, dengan galat maksimum sebesar 163% untuk H/D = L/D = 0,1, serta 34% pada kasus uji 5.11 dalam dokumen CIE 171:2006, sehingga dapat menimbulkan kesalahan yang serius dalam praktik desain bangunan.
