Daylight for Spaces Defined by Movable Walls

The present article deals with the designing proper interior spaces in a reconfigurable manner while at the same time ensuring the much needed daylight for people spending a considerable amount of times indoors. The necessity for this study has appeared as part of a design effort of a furniture start-up company interested in producing movable walls for office and conference spaces, when it became apparent that many times the spaces obtained in this way are devoid of natural sunlight. 3D modeling software was used for creating the desired configuration and a specialized lighting simulation software, DIALux, was employed to study the possibilities of improving lighting conditions. The paper presents an approach that can be used to design and configure hybrid lighting systems, obtaining improvements in lighting costs of up to 30% for interior spaces defined by movable walls.
