| Abstract: | Superiority of advanced, innovative design tools. In Germany, standard building design is often determined in the traditional way that is, solely according to the HOAI (Official Scale of Fees for Services by Architects and Engineers) 1]. This means that in most cases only simplistic design tools are used by default. However, with high‐class complex buildings these are not always an adequate means of ensuring that the often stringent requirements their use places on the indoor climate conditions are met once they are in operation. In ambitious buildings featuring numerous open areas inside and open exits leading outdoors or to adjacent buildings but still place stringent requirements on the indoor climate conditions, the interactions between the individual areas inside and between these and ambient air are extremely important. Such buildings often appear transparent so as to look attractive to visitors: keeping entrance doors open helps to attract the attention of passers‐by and to make the buildings seem more inviting. The resulting streams of visitors necessitate a multiple open doorways, resulting in more or less strong airflow within the buildings. The effects of this wind‐ and buoyancy‐induced airflow on the indoor climate conditions proposed for a particular building can only be evaluated by means of advanced innovative design methods in the form of simulation technology. The airflow inside the buildings raises a number of very different issues regarding their design which can only be resolved by means of different simulation techniques. Using the new entrance building (NEG) on Berlin's Museum Island as an example, typical design issues are exemplified and the corresponding simulation techniques presented here. In this way the – urgently needed – transparency concerning the application of building simulation technology is encouraged. |
