Description
In 2020 Vienna converted Esterhazypark into its first Cooling Park, combining a misting Coolspot pavilion and mist showers (delivered with Raintime GmbH), depaving, 8,600+ perennials, and a 400+ m² green wall on the park's WWII flak tower. The city reports local cooling of up to 6 °C, though this figure comes from the city and vendor and has not been independently verified. The cooling effect is hyper-local, creating comfort pockets rather than neighbourhood-scale temperature reduction. The park is sited in Mariahilf, a comparatively well-off district, raising equity questions about siting priority.

Lessons learned
- Misting delivers strong but hyper-local relief: treat it as climate-adaptive street furniture creating comfort pockets, not area cooling.
- Vendor and city cooling figures need independent measurement before they justify replication budgets.
- Active misting systems carry recurring water and energy costs that must be budgeted for every future summer.
- Siting flagship cooling projects in well-off districts undermines equity; prioritise the hottest, poorest blocks first.
