Climate-based daylight simulation as a planning aid for the design of solar façades

Grobe, Lars Oliver (Autor/in); Wittkopf, Stephen (Autor/in)

Climate-based daylight simulation allows performance predictions for façade designs based on available climate data. Simulations based on daylight contribution coefficients coupled with models of sky luminance distribution make this tool available even in the design process. Metrics describing glare probability and the potential to substitute electrical lighting by daylight are applied and design proposals iteratively improved. The method is demonstrated on an existing building, the \textquotedblleftNeubad Lucerne\textquotedblright, which is subject to design studies by students of architecture. Proposals to extend the two South-facing facades are developed, aiming at lower glare probability and optimized use of daylight to minimize electrical energy consumption for lighting. This paper shows: a) The different façade designs in photorealistic renderings. b) The quantitative analysis of useful daylight illuminance and daylight glare probability. c) A comparison of the designs according to the predicted daylight glare probability. Finally, It closes wih a comment on using climate-based simulation as a design tool.
