The technical collaboration between ALLPLAN and EDILCLIMA offers a new opportunity to make the most of the potential of BIM design. In fact, it is now possible to export the Allplan model in IFC format for subsequent processing in EC700, the solution for calculating the energy performance of buildings in compliance with UNI/TS 11300 technical specifications. During the technical seminar, the potential of exchanging data in IFC format between the two softwares will be demonstrated, with the use of a real project of a house. (italian only)
