Benefits of BIM in the thermal performance management

The importance of analysing thermal performance in building design has grown, but it is still often done using simple static calculations or estimates. Accurate dynamic thermal simulation software have been available already for decades, but these tools are still not widely used by practitioners in building projects. The main barrier of wider usage of dynamic thermal analysis methods has been the required big manual input work. By utilising BIM as a data source for hermal analysis, the data input will be more efficient and the existing data more reusable. BIM facilitates easier verification of the thermal performance in different phases of the building process. This paper shows the recent developments for new oncept and interoperable software environment to manage spatial thermal performance during the whole building life cycle. Results of using the developed concept are shown from real projects.
