Dynamic Shading in Buildings: a Review of Testing Methods and Recent Research Findings

Abstract

The use of dynamically operated shading has been shown to provide energy savings and occupant visual and thermal comfort needs. As the literature in this area continues to grow, including development and evaluation of a range of shading devices, control strategies, and simulation and experimental test methods, a review is merited to assess the current state of the art. While roller shades and venetian blinds are most common, there are a growing number of additional shading types considered, as well as more complex control logic, some of which directly integrates occupant feedback. In addition, the majority of dynamic shading evaluation continues to be through simulation-based methods; however, there is an increasing amount of research using experimental methods. Some research has also explored combination simulation and experimental methods to simplify the number of sensors needed and associated complexity. Improvements to control logic and ranges of test scenarios continue; however, there is still significant need for further studies in this area.
