Vienna’s cool networks

Vienna is a poster child for innovative waste management. Since the 1990s, Austrians have cut the amount of waste they send to landfills – even passing laws to restrict their use.

Recycling is encouraged but the city also incinerates large quantities of rubbish to create energy for heating and, more recently, air conditioning.

It’s called ‘district cooling,’ more environmentally friendly and efficient than conventional air conditioning. Vienna, named the world’s greenest city, believes that district cooling will be playing a key role in decarbonizing the energy market.

The summer temperature in Vienna is expected to rise by 7.6 degrees Celsius in the next 30 years. This is why the Austrian capital is now expanding its district cooling network, using 70 percent less energy and produces 50 percent less CO2 than conventional solutions.

With the help of waste incineration, a cooling liquid is produced to lower room temperatures in hotels, offices and flats.
