The subject of this paper is the application of a method for the assessment of temperature-related climate risk in accordance with the EU Taxonomy, based on a dynamic simulation method for predicting the thermal behaviour of a building. A mathematical model is used to dynamically simulate the behaviour of the whole building, zoned into above ground and underground floors. The aim is determining the total heat and cooling needs and resource performance to maintain the desired indoor environmental state for the whole building with typical operational profile under current climatic conditions (TRY for Prague), current extreme and future climatic conditions (taxonomy requirements).
