On the one hand, the two-part add-on Optimization & Costs / CO2 Emission Estimation finds suitable parameters for parameterized models and blocks via the artificial intelligence (AI) technique of particle swarm optimization (PSO) for compliance with common optimization criteria. Moreover, this add-on estimates the model costs or CO2 emissions by specifying unit costs or emissions per material definition for the structural model.
