summary 
This paper presents Opossum, a new optimization plugin for Grasshopper, a visual dataflow modelling software popular among architects. Opossum is the first publicly available, modelbased optimization tool aimed at architectural design optimization and especially applicable to problems that involve timeintensive simulations of for example daylighting and building energy. The paper details Opossum's design and implementation and compares its performance to four singleobjective and one multiobjective solver. The test problem is timeintensive and simulationbased: optimizing a screened façade for daylight and glare. Opossum outperforms the other singleobjective solvers and finds the most accurate approximation of the Pareto front.
