jailcd2020004: Daylight Visualization Analysis of Student Workspace in The University of Kitakyushu

Abstract

Daylighting is supposed to accommodate the occupant's visual demand to minimize peak energy demand. This research measure visual comfort using the level of illumination and light distribution in the room (uniformity values) and add some design interventions to reach recommended daylighting values according to the daylighting standard. To achieve this goal, lux meter is used as a manual way and VELUX Daylight Visualizer to measure the uniformity and daylight factor. Besides daylight factor minimum (DFmin)/ daylight factor mean (DFmean) at least be 0.4% or the minimum point of daylight factor should be at least 0.8%. The addition of curve light shelf and change the floor material increase the uniformity value from 0.2% for baseline case, become 0.6%, and the daylight factor minimum from 0.45% for baseline case become 0.97% after the design intervention.
