All of these aspects need enough space to be working effectively. Thus, if this two of three aspects can be combined, space efficiency can be reached. This paper studied the integration of luminare-diffusor effects to lighting and acoustical performances. This research did experiments with four lamps luminaries attach with a varied diffusor on it’s surface. There are four diffusor variation which are QRD N7 d max 15 cm, QRD N7 d max 10 cm, QRD N11 d max 15 cm and QRD N11 d max 10 cm. All these diffusors works on human speech frequencies. Photometric data of the luminaries were taken before and after the integration took place in order to analyze the significant difference between the two conditions. The diffuse coefficient measurements were also taken to distinguish the quality of the acoustical performance. Result shows that acoustic panel diffusers variation did not change the lighting intensity distribution and the average illuminance on the work space significantly. Thus, the best integration determine by the highest diffuse coefficient was acquired by QRD N11 d max 10 cm.[/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]Acoustical performance,Classroom acoustics,Coefficient measurement,Human speech,Lighting intensity,Photometric data,Space efficiencies,Thermal conditioning,Work space[/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][/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]
