The “Sponge City” Principle: Smart Open-Space Design in Esterházy Park in Vienna

Heat waves, droughts, and heavy rainfall events pose enormous challenges for our cities. The consequences of climate change call for innovative, sustainable solutions that both mitigate flooding and improve the microclimate. One of the most effective approaches is the “sponge city” principle, as implemented here in Esterházy Park in Vienna.

Heat waves, droughts, and heavy rainfall events pose enormous challenges for our cities. The consequences of climate change call for innovative, sustainable solutions that both mitigate flooding and improve the microclimate. One of the most effective concepts is the “sponge city” principle, in which cities are designed to function like a sponge: They absorb rainwater, store it, and release it back into the environment as needed. An outstanding example of the successful implementation of this principle in a public space is Esterházypark at the Haus des Meeres in Vienna, which opened in 2020 as...
