For this purpose measurements and a survey of the current sound immissions were carried out and assessed. The existing air pollutant immissions were determined by means of the air measurement network of the MA22.

In a second step a computer model was developed for the project. The emissions in the area of the garage ramp and those caused by the parking actions in the garage itself were calculated according to the currently valid laws, standards and guidelines and formed the basis for the model. By means of dissemination calculations the immissions at the nearest neighbouring buildings were subsequently determined and compared to the limit and guide values.
