The RFEM add-on Building Model allows you to define and manipulate a building by means of stories. The stories can be adjusted in many ways afterwards. Information about the stories and also the entire model (center of gravity) is displayed in tables and graphics.
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. On the other hand, this add-on estimates the model costs or CO2 emissions by specifying unit costs or emissions per material definition for the structural model.
