Between 1961 and 1990, Vienna experienced on average 9.6 heat days per year. From 1981 to 2010, the number of heat days rose to 15. According to forecasts, there will be an average of 19 hot days between 2021 and 2050, and 41 between 2071 and 2100. Moreover, the population is expected to increase from 1.8 million to 2 million by 2029. To protect the population from the consequences of heat events, the Energy Planning department of Vienna decided to take action.
We study the urban needs.
We define relevant indices to take into consideration for heat assessment.
Based on our algorithm, we map the sub-indices and combine them to create the Urban Heat Vulnerability Map.
We customise environmental solutions to cool down critical hotspots.
