Daylight and solar radiation “in situ” evaluation in the scope of Naturelab project

Abstract

Daylight and solar radiation are essential factors that influence the quality of life of all living beings. In the scope of Naturelab project, the main objectives of the daylight and solar radiation (DSR) evaluations are the assessment of how both daylight and solar radiation can contribute to the health, comfort, and well-being of individuals in outdoor spaces. Additionally, the potential positive effects of those factors are also evaluated as part of therapeutic programs. For this purpose, a set of indices and indicators are proposed based on on-site evaluation of the luminous environment and also based on the statistical analysis of groups of individuals regarding the before mentioned outdoor luminous environment. This paper presents the main on-site procedures for the characterization of the daylight and solar radiation components of the outdoor environment. The preliminary results indicate the influence of natural light and solar radiation in improving the health, well-being, and comfort of individuals in leisure and healing contexts.
