Urban Cooling Demand Vienna

In accordance with Article 25 of the EU Energy Efficiency Directive (EED III, Directive (EU) 2023/1791), municipalities with more than 45,000 inhabitants are bound to draw up local plans for heating and cooling supply from 2025 onwards. These plans must include specific requirements, existing infrastructure and possible potentials, with energy efficiency being the top priority. Such plans must be based on a thorough understanding of how heating and cooling requirements are likely to develop. In combination with efficiency-enhancing measures, various development scenarios should be mapped out and incorporated into the formulation of urban cooling strategies. Based on the results of the R&D service "Urban Cooling Demand in Austria (UKÖ) 2030/2050" commissioned by the BMK and drawing on the results of detailed building simulations carried out by the customer, taking into account the specific characteristics of large cities (e.g. with regard to the building stock), the project objective is to examine in what spatial and factual resolution (1) publicly available data can map the spatially relevant influencing factors for the cooling demand of a large city and (2) the cooling demand can be determined using the example of the city of Vienna in the status quo and up to the year 2050.
