Vienna arms on: New remote cold against the tropical night heat!

Floridsdorf, Österreich - Vienna is very evident: On June 8, 2025, the city already experienced the first tropical night of the year, with temperatures of over 20 degrees. In view of this development, Vienna Energie has launched a comprehensive program for modernizing and expanding the remote fold system in order to cover the growing cooling requirements of the population.

as [5min] (https://www.5min.at/5202506080859/erste-tropennacht-2025 wien-baut-fern-weiter-aus/), the new long-distance cold center in Floridsdorf will be the first measure. It goes into operation together with modernized facilities and a comprehensive renewal of the long -distance cooling center at the Schottenring. This is necessary, because 2024 set a new record with 53 tropical nights in the city center and it cannot be assumed that this trend is reversed in the coming summer.

investment in the future

Wien Energie will invest around 90 million euros in the expansion of the system in the next five years, which is essential for both comfort and health protection for the population. Another innovation is the ice storage that is built at the MedUni Campus. It should intercept the tips of the consumption and further increase the efficiency of the new refrigeration center. Commissioning is already planned for this summer, so that Vienna can go into the hot months.

The new chillers have a significant increase in capacity: the exchange of old machines increases the total output by 1.9 megawatts, so that the total capacity is 20 megawatts. The new remote cold center in Floridsdorf will also supply the Central Hub office and business park directly with 6 megawatts.

efficient cooling on the advance

as [today] (https://www.heute.at/s/neue-kaeltemaschinen-wienruestet- against-tropenhitze-auf-120112412) emphasizes, this system not only makes a contribution to cooling, but also to sustainability. Long-distance cooling saves over 50 percent CO₂ emissions compared to conventional air conditioning systems, which is particularly important in times of climate change. The coldering, which was completed in 2024, connects the various remote cooling centers in the city center and enables a better distribution of the cooling capacities. The long -distance cold network currently supplies around 200 buildings with a total length of around 30 kilometers and a refrigeration power of 230 megawatts.

The need for these investments is reinforced by the further. Due to their sealed areas, traffic and other factors, cities are often hotter than the surrounding area. In these situations, cooling through technical solutions such as long -distance cold becomes particularly important in order to keep the standard of living in urban areas.
