AbstractDaylighting posses a good potential for application in the tropical climate. It can also accrue benefit in term of reduction in electricity for lighting. This study investigates daylighting in a experimented room in the AIT energy park. Experiment were conducted for four scenarios of daylighting and artificial lighting integration. The four scenarios cover the case of overall uniform lighting and non-uniform lighting arrangement, and two lighting control methods, continuous and step dimming. The resultant savings in energy for lighting ranges 68-86% in comparison to a base case. The investigation also includes an estimation of the net heat gain into the building from daylighting and from electric lighting, which forms part of the cooling for the air-conditioning system. During the course of daylighting experiments, a number of follow student were requested to assist in the evaluation of daylight comfort under al four scenarios of daylighting-artificial lighting integration. Continuous dimming received favourable responses from the subjects. Step-dimming on task areas tended to produce unfavourable responses.
