This project is part of the new territorial study of the Bubny-Zatory in Prague, Czechia by the Prague Institute of Planning and Development (IPR Prague). A new urban design is being proposed to revitilise the brownfield area for developing a green, liveable and extreme heat resilient urban environment in the Bubny-Zatory district.
For this project, a 3D model was developed from the architectural design of the newly developed Bubny-Zatory urban design. Buildings, roads, sidewalks, courtyards, and trees were placed according to their respective positions.
With all the above-mentioned parameters as inputs for the simulation, ECOTEN urban comfort s.r.o. was able to simulate the urban microclimate for the urban design and produced results for 5 extreme heat days and 2 average summer days. These days were selected based on the hottest consecutive days of the year 2018, when Prague experienced one of the most severe heat wave seasons of all time (according to the weather archives of the Czech Hydrometeorological Institute).
The urban microclimate simulation was performed using a software suite called SOLENE-microclimate, which takes into account the coupling of a thermal model, thermal-radiation model, and a computational fluid dynamics (CFD) model. For simulating the impact of evapotranspiration from blue and green areas, the Penman-Monteith equation for potential evapotranspiration.
