This graduation thesis explores possibilities of BIM uses for sustainable design. For that purpose I first
analyzed definition and aspects of sustainable building, criteria for analysis of sustainable building
according to the LEED, BREEAM and DGNB methods and identified possible BIM uses. For BIM
uses I considered environmental and social aspects of sustainable building design, such as analysis of
building orientation in the environment, proper shading, sufficient daylight and energy analysis.
In the practical part of the thesis conceptual models for a selected case study were designed. I
examined analysis of sufficient daylight, shading and exposure to the sun. In the SketchUp program I
designed simple 3D model, and then used different plugins for shading and daylight analysis. Part of
the building information model was imported to Velux Daylight Visualizer, in which daylight analysis
was performed. Results of the daylight and shading analysis were examined according to the technical
guideline TSG-1-004:2010, based on European Directive EPBD 2002 and renewed Directive EPBD
2010. A simplified 3D model was created within Ecotect Analysis program for incident solar radiation
analysis of the envelope. Latter data was used to determine the amount of energy received on the
building envelope. Later, the energy analysis was done within Knauf Insulation Energy program on
the basis of 2D blueprints. Appropriate quantities were measured in the CostX program. Energy
analysis was also conducted within ArchiCAD program and Energy Evaluation plugin based on the
bases of the building information model. Finally, detailed comparison of the results was made, due to
possible discrepancy in results of different assumptions and input data.
