The Passathon 2023 – RACE FOR FUTURE is the world’s largest outdoor event for climate-friendly building and renovation and will start on April 7, 2023. 671 climate-friendly buildings in 240 communities show how the shift from oil and gas to energy efficiency and renewable energy can succeed.

Vienna. March 21, 2023. The upcoming negotiations on financial equalization between the federal government, states and municipalities are of particular importance for climate protection. RENOWAVE. AT, the innovation laboratory for climate-neutral renovation of buildings and districts, is therefore calling on the financial compensation negotiators to put the right measures in place to achieve a successful heat transition.

In 2024, the ETHOUSE Award, the prize for energy-efficient renovations in Austria, will be presented for the twelfth time.
Ethouse invited housing researcher Wolfgang Amann, cooperative member of RENOWAVE.AT, for a talk on this occasion. He exchanges views on building renovation in Austria with Clemens Hecht, spokesman of the ARGE Quality Group for Thermal Insulation Systems.

The core of the project is the greening of the roof and façade of the 130-year-old building and, above all, the use of a so-called gray water system: heat is recovered from contaminated wastewater for hot water and used for toilet flushing and irrigation as well as for room cooling.

For the exhibition “Klima. Wissen. Handeln” at the Vienna Museum of Technology, Constance Weiser from RENOWAVE.AT provides exciting insights into how the construction sector can become more sustainable.
