Vienna arms on: Millions of investment against tropical heat!

New cold in Floridsdorf

Another heart of the project is a newly built distance cooling center in Siemensstrasse, which already went into operation with 6 megawatts. This will play an important role for the big city, where cold is no longer just a question of comfort, but also health protection. Another cold center is being built at the MedUni Campus, which will soon go into operation with an ice storage.

The new remote fold system is not only efficient, it also protects the environment: the freshly used machines cool water to 5 to 6 degrees Celsius and save over 50 percent of CO₂ emissions compared to conventional air conditioning systems. Around 200 buildings benefit from this 30 -kilometer long -distance cold network, which has a total output of 230 megawatts. There is something!

heat in the city and the protection of our trees

But what contributes to the warmth in our cities? The so -called heat island effect shows that urbanization and sealed areas are responsible for significantly higher temperatures, especially in the summer months. According to a study by the University of Hamburg, old street trees are particularly important because they donate energy in the form of shade and absorb CO₂. Older trees that are 40 years or older are particularly worth protecting. They have proven to be resistant to various environmental factors and are therefore a real city green rescue team.

Unfortunately, many trees in cities such as Vienna are strongly at risk through factors such as compression, dirty air and a lack of suitable water. It is high time for a rethink so that we can continue to support our green city dwellers. If old trees have to be felled in construction measures for hygienic or safety reasons, irrevocable losses are done that can have a negative impact on urban air quality and microclimate.
