Lighting Optimization for Reused Building; Case Study of PLN Convention Hall, Soekarno Hatta, Bandung

Abstract

Changing the function of a building can have an impact on the lighting required for the installation. This research aims to simulate and compare the need for optimal natural lighting and reduce artificial lighting in a building that functions as a Sports Hall. PLN Sports hall will be redeveloped into the PLN Convention Center Building in Soekarno Hatta Bandung. WWR is a suggestion for optimization without changing the structure and architectural aspects of the building. The analysis is based on lighting and shadow from the Energy Plus Weather File, and then these parameters are processed using honeybee to create more precise WWR variables. Lighting analysis is simulated with two building functions: namely the variable time and different ranges, following the Illumination Standards by IES and SNI. This study’s results are divided into four simulations and three various iterations where the existing conditions have an area below 300 lux as much as 93.45%. For natural lighting below 300 lux, it is 60.94%. With the placement of openings based on optimum radiation analysis, artificially below 300 lux is 2.3% (already enter the category of adequate - well lit) and a combination of under 300 lux by 0.30%. The existing conditions are categorized as underlit, iteration 1 is adequate, and iteration 2 and 3 are in the well-lit category.
