Illuminance measurements within a scaled office room under a novel building-integrated concentrator PV module presented at the 42nd European Photovoltaic Solar Energy Conference and Exhibition

This dataset contains data of illuminance distribution measured within a scaled office room under the novel building-integrated concentrator PV module presented at the 42nd European Photovoltaic Solar Energy Conference in Bilbao (EUPVSEC 2025) through the oral presentation "Fabrication of a Novel Semi-Translucent BIPV Module Providing High Power Density and Active Daylight Management" by Almudena Garcia-Sanchez. This dataset includes measurements of illuminance were carried out outdoors using a luxmeter with the module installed horizontally on a scaled office. The dataset includes:• Peak illuminance at the room inner surfaces for different angles of incidence• Matrices of illuminance distribution on the wall and floor surfaces of the scaled office room, with direct sunlight impinging at a transverse angle of incidence AOIT = 45° The authors gratefully acknowledge the support from project grants: MICROBEAM ref.
