Abstract: This paper focuses on possibilites for simple, low-cost, manual adjustable lighshelves in comparison to static light shelves, which typically do not utilize their optimal potential of daylight harvesting due to lack of access to optmization procedures. A framework is presented on how to identify optima for seasonal manually adjustable light shelf configurations for a given context. After developing performance evaluation criteria for such light shelves, the study proceeds to identify a process to identify optimal parameters for selected cases, using a reduced set of light shelf variables, as a proof-of-concept. The optimization method is based on a seasonal assessment loop utilizing climate based daylight modeling, carried out in DIVA, controlled by Grasshopper with Daylight Autonomy (DA) as the performance metric. The study concludes with an outline of a framework for manually adjustable light shelf selection.
