Transkriptio

1 BuildingEQ-Symposium in Berlin, October 1, 2009 Making use of BIM in energy management Tuomas Laine Olof Granlund Oy

2 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

3 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
