Vienna Energie starts with new remote cold in hot summer 2025!

Wien, Österreich - Today, on June 5, 2025, the Viennese citizens experience the first tropical night of the year because the temperatures do not drop below 20 degrees Celsius. This development is a sign of rising temperatures and the reinforced tropical nights that have increased in the capital in recent years. Against this background, Vienna used energy to prepare the winter months to optimally prepare the long -distance cold for the upcoming summer time. In the summer of 2024, the city center already recorded 53 tropical nights, which illustrates the increasing need for cooling.

In order to meet the requirements of a hotter summer season, Wien Energie is investing 90 million euros in the expansion of long -distance cold. The essential measures include the exchange of the chillers in the Far Kältezentrale Schottenring, where old machines were expanded with a crane and replaced by modern systems. The installed performance of this headquarters could be increased by 1.9 megawatts to a total of 20 megawatts. In addition, a new remote cooling center in Siemensstrasse was put into operation with an output of 6 megawatts, which supplies the Central Hub office and business park and also offers capacities for other customers.

Another exciting step is the planned commissioning of a new cold center at the MedUni Campus, which is equipped with an innovative ice storage. This measure is not only used in summer, but also for efficient cooling in winter. Long -distance cooling is generated in specialized central centers with highly efficient chillers, whereby cold water is led to the customers at temperatures of 5 to 6 degrees Celsius via isolated lines. The long -distance cold is not only used in the hot season, but is also required in winter, for example by large customers such as the AKH, data centers, large kitchens, hotels and cultural companies.

The advantages of the remote cold should not be underestimated. It saves over 50 percent of CO2 emissions compared to conventional air conditioning. Unlike air conditioning systems that generate waste heat and also heat up the urban environment, the remote fold system helps to reduce the heat in urban areas. This is particularly important because temperatures in cities like Vienna can be up to 10 degrees higher than in the surrounding area.

facts about the remote cold

• network length: 30 kilometers
• Total refrigeration work: 230 MW
• supplied buildings: 200
• CO2 savings: 50% compared to conventional air conditioning
• Number of cold locations: 7 Remote cooling centers with mains connection and 17 decentralized solutions

The continuous expansion of the remote cold network is an important step towards sustainable urban development. A distinctive milestone was the end of the colder in 2024, which significantly improved the infrastructure. In similar efforts, other cities, such as Munich, also rely on the expansion of long -distance cold networks to combat the urban heat islands and to ensure environmentally friendly cooling. Compared to traditional air conditioning systems that are energy -intensive and further heat up the environment, the remote cold offers a much more efficient solution that meets both ecological and economic requirements.

In summary, it can be said that Vienna is proactively encountering the challenges of climate change by driving innovative technologies for cooling and thus making an important contribution to the reduction of CO2 emissions.
