The effects of climate change are becoming increasingly noticeable to us all. The number of hot days in summer is rising, particularly densely built-up urban areas are cooling down perceptibly less at night, and slowly but steadily the flora and fauna are also changing. Vienna "moves" a bit farther south on the European map every year, within 30 years we might record average temperatures of Naples today. In addition to all the measures being taken to counteract the causes of climate change, it is therefore also necessary to respond to its already noticeable effects. In other words: environmentally friendly construction methods, renewable energy systems and the effective prevention of emissions. At the same time, we must provide for more shade, cooling islands, green facades, rooftops and public areas. Together, these measures will ensure that our city remains worth living in for future generations, too.
Biotope City on Wienerberg is an urban district that meets the requirements of climate adaptation. From the very beginning, all the actors involved have worked together on the basis of the "Biotope City" model. The Biotope City Foundation developed a model that aims at the intelligent use of nature's regenerative mechanisms to mitigate problems in cities caused by climate change and pollution.
Many measures that represent significant progress compared to conventional planning are often not visible after completion. These invisible building blocks - Hidden Treasures - make a significant contribution to cooling down the district and the surrounding area.
Within the framework of 50 Grüne Häuser (50 Green Houses), an integrated combination solution for retrofitting existing buildings with greenery on the street side is being developed for the first time.
GRÜNSTATTGRAU is an independent innovation laboratory specifically dedicated to the topic of renovation in existing urban buildings using greenery.
In the LiLa4Green research project, researchers and residents are working together on how to better deal with increasingly hot summers in the city.
The HOUSEFUL project researches and develops innovative circular solutions and services for the housing sector.
Vivihouse is an innovative construction system for the erection of multi-storey buildings for mixed uses. It is based on a modular timber frame construction that is specially optimised for the use of renewable materials.
MGG22 is more than just a normal housing project. Here, for the first time, thermal component activation is used for heating and cooling in social housing. This means that a year-round supply of 100% renewable energy can be ensured!
The Waldrebengasse project in Stadlau represents the great innovative power of the Viennese housing model. The IBA candidate combines a future-oriented and climate-friendly construction method with strong social offers and affordable housing.
Wood as a building material is being used more and more in non-profit housing and is now also being used extensively in the load-bearing structure and exterior design. The system construction method with a high degree of prefabrication should bring economic and technical advantages. Intelligent hybrid solutions of wood and concrete combine the advantages of both building materials in terms of fire, sound and weather protection.
Examples:
Stories were recorded for all IBA neighbourhoods as part of the Interim Presentation. Please note, the audio-stories are in German only.
Architectural models play an essential role in the planning process, as they make ideas and concepts visible and tangible. In the exhibition "How will we live tomorrow?" the models were therefore an important building block to enable a holistic view of the project.
