In designing such a system, computational modelling and simulation are a powerful tool to predict its performance. In that case, it is important to ensure that all relevant simulation parameters have been defined appropriately so that the results can be held reliable. This study, therefore, aims to investigate the impact of ambient parameters on the performance of ADS, using modelling and simulation. In this study, an isolated room with no windows is modelled and rectangular ADS is modelled in the room. The inlet of the ADS is set with 60° angle, placed in the east facade. The whole model is simulated in DAYSIM and Radiance, under the CIE overcast and Perez sky model with climate data of Bandung, Indonesia. The Radiance simulation parameter of ambient bounce (ab) is varied from 2 until 8. Daylight metric which is Daylight Factor (DF) is observed to determine the sensitivity of ab parameter. The results suggest that ab parameter of 5 yields the best performance regarding DF.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Anidolic Daylighting System,Daylight,DAYSIM,Radiance[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
