The thesis deals with the concept of building design known as Building Information Modeling (BIM). Abroad, this concept of modeling has already been well established in design bureaus, but it is still in its infancy in Slovenia. Since mechanical engineers also play an important role in the construction industry, there are special modeling programs for the design of building systems. This includes the DDS-CAD program, which we used on the selected building for the design of ventilation systems.
For example we chose the building Gimnazija Vič, and its annex of the gym, library and multipurpose rooms. Depending on the two-dimensional building plans, we developed a model and ventilation systems in three dimensions. From the program we obtained data from ventilation systems, such as used elements, the calculation of air flow and pressure drops. We defined the structure of the walls, and obtained data for heat losses of the building.
