Analyzing the Daylight Performance and its Impact on the Energy Consumption Rate of Selected Yeka Abado Condominium Buildings

Adequate daylight is an implicit element for the indoor environment, which is an asset to health that lowers depression, ensures the occupant's thermal comfort, maintains the room?s functionality, creates the desired environment, and reduces the energy consumption rate. The study focuses on assessing daylight performance and its influence on artificial light usage in buildings. This research-based on survey analysis, building performance simulation, cross-checking method, and secondary data review and analysis. The study was carried out on the sunny season of the location to assess and experience the lighting performance. The study has shown that dominant houses/rooms have daylight complications including insufficient performance, sometimes overpass the acceptance range and confirmed its impact on the electric light consumption. The result also shows that the available daylight in the buildings influenced by the urban context, building form, orientation, and the fenestration design. To improve the natural light performance having a daylight strategy is essential with the evaluation technique at the early designing stage. Appropriate passive and active design strategies are also recommended.
