MODELLING OF INTERIOR SHADING SYSTEMS FOR DAYLIGHT AVAILABILITY GLARE AND THERMAL CONTROL

Abstract

This research is devoted to the influence of interior shading systems on occupant comfort within a Mediterranean high-rise building. Through modelling the performance of various shading configurations such as vertical horizontal and roller blinds was assessed. Results demonstrate that while interior shading can effectively mitigate glare it has a minimal impact on thermal comfort. Horizontal slats oriented at a 90° exhibited optimal performance in terms of daylighting and glare control. However the limited influence on thermal conditions suggests that exterior shading may be necessary to achieve substantial improvements in building energy efficiency. The findings underscore the importance of a site-specific approach to shading design considering factors such as building orientation glazing properties and climatic conditions. © 2025 Elsevier B.V.
