After more than eight years of intensive standardisation work, the second part of the German DIN 18009 standard on "Simulation of evacuation and personal safety" was published in August 2022. The DIN 18009 series deals with fire protection engineering for Germany. The first part "Principles and application rules" was published in 2016, with further parts describing standards for smoke simulation and safety concepts to follow. DIN 18009-2 [1] standardises the performance-based approach for conducting evacuation simulations. It builds on earlier pre-standards such as the German RiMEA Guideline [2] as well as international standards such as ISO/TR 13387-4,16738BSI PD 7974-6 (British) or the CFPA-E Guideline No. 19. It is a milestone for the simulation community as it emphasises the growing importance of simulation models in the building design process and in fire safety. It places new requirements on existing models and evaluation procedures and gives modellers and authorities guidance on how to use simulation as a useful tool in their projects. The new standard provides a step-by-step approach to defining scenarios and performance criteria, selecting the simulation model, and documenting and analysing the results (see Figure 1). Various safety criteria, such as total evacuation time and congestion analysis, are introduced to evaluate and interpret the results. While the required evacuation time can be analysed by a simple comparison of ASET (Available Safe Egress Time) - RSET (Required Safe Egress Time), the standard gives engineers more leeway when analysing congestions: In the current version, no specifications are provided for the evaluation of congestions, since congestions are not inherently dangerous and even occurs in buildings that comply with building regulations. The standard makes it the user’s responsibility to assess the congestion in the context of the use case. To support the user, the standard provides several metrics, such as duration, location and size of congestion, delay time through congestion as well as congestion density. The paper gives an overview of the new standard and discusses the open issues that do not provide clear guidance to modelers in terms of congestion analysis. We also outline what knowledge is needed from a modelling perspective to be able to perform standard-compliant analyses in the future.
