Development of an Information Delivery Manual for Early Stage BIM-based Energy Performance Assessment and Code Compliance as a Part of DGNB Pre-Certification

The evolvement of integrated practices utilizing Building Performance Simulations has made it possible to address the growing needs of the building design. Furthermore, including a sustainability rating system in the early stages ensures a superior environmental performance and a common goal for all parties involved. However, the persistent lack of early collaboration and process standardization prevent reaching the full potential of BIM-based performance evaluation. By following buildingSMART’s methodology for development of Information Delivery Manual/Model View Definition, this paper presents a framework for BIM-based energy performance assessment and code compliance, as required by the Danish Building Regulations and the DGNB rating system. Standardization of the information exchange would increase efficiency and reduce manual data input, duplication of work and errors due to miscommunication.
