BuildingEQ-Symposium in Berlin, October 1, 2009 Making use of BIM in energy management Tuomas Laine Olof Granlund Oy www.buildingeq.net
Content BIM based tools for energy performance analysis and thermal requirements management Utilization of BIM in performance reporting during operation Example: Senate properties, building owner of Finnish governmental buildings Implementation of tools in BuildingEQ demonstration buildings Requirements and guidelines for energy performance management and BIM utilization 1
Tools used in Finnish demonstration buildings State Treasury, Helsinki, office building - RIUSKA, energy analysis HUT Engineering department, Espoo, university building - RIUSKA, energy analysis - ROOMEX, requirements management Aurora 2, Joensuu, university building - RIUSKA, energy analysis Senate headquarters, Helsinki, office building - RIUSKA, energy analysis - Taloinfo, self-reporting building All were also visualized by BuildingEQ tool Senate properties gave 4 demonstration buildings for 2 BuildingEQ
