| Summary: | Illuminance in spaces is important criteria in rating building performance. These also
a strategy to develop some passive design criteria to meet the occupant visual comfort. The aim
of this study is to investigate the fluctuation of the illuminance level and the impact of
daylighting in an optimum performance zone. This study also investigates the effects of occupant
density whether affect the illuminance level in two selected office buildings. Qualitative survey
has been conducted on the occupant’s perception toward visual comfort and obtaining the
comparison on the glare effect by using IESVE computer simulation while visual test has been
conducted involving selected workers. The maximum occupant density and physical conditions;
window to wall ratio of 25%, 40% and 70% of typical office space were identified by using
IESVE simulation. Findings from experiment of visual performance and daylighting simulation
showed more than 50% occupancy in typical office room with 70% of WWR affected the extend
of the daylight zone and the acceptable of illuminance level is not achieved. There high contract
between 50% of the occupancy in a room is also changed the illuminance level of more than
26%. The findings contribute towards the improvement of an acceptable visual comfort ranges
and design recommendations for optimum performance zone in a single office space in Malaysia. |
