  • IBPSA-Italy is the Italian regional affiliate of the International Building Performance Simulation Association (, but it acts in total independence.
  • IBPSA-Italy’s principal mission is to promote and advance the practice of building performance simulation in order to improve the design, construction, operation, maintenance of new and existing buildings.
  • IBPSA-Italy’s objective is to provide a forum for the exchange of information and promote collaboration among researchers, developers and practitioners acting on the topic of building performance simulation and related issues, and promote training.
