In an embodiment, a computer-based method for automatically selecting resources to include in a building plan layout is disclosed. The method involves obtaining a set of resource rules that define resources placeable within a building plan layout, obtaining a set of behavioral rules that define the behaviors of the resources, generating a model by evaluating the set of resource rules and the set of behavioral rules, obtaining a configuration, wherein a configuration comprises at least one of building demand, resource permutations, and other simulation attributes, generating at least one set of performance metrics by executing the model with the configuration, storing the at least one set of performance metrics, the model, and the configuration as an entry in a metrics database, selecting an entry from the metrics database, and outputting the entry to a building plan layout generator.
