Optimizing the luminous environment using DiaLUX software at “Constantin and Elena” Elderly House – Study Case

The spatial and luminous optimization of the living environment of the elderly is now a major problem, reflecting the growing desire to meet their needs. It's common to design efficient lighting environments through the use of specialized design software, using standard parameters. The design of a lighting system for elderly today shakes up these habits. It modifies the design parameters and requires specific new parameters, meeting their specific needs. This non-hypothetical and different design process was tested here through a case study in a retirement home. It will develop a type of design based on contrast of luminance against illuminance ratio, leading to the development of a guide to good practice, thanks to which the CAD had to have a substantially better performance with DIALux Evo. Expanding even further the lighting design and accuracy of details, an original approach based on MATLAB functions are demonstrated.
