District Renewal, Energy Efficiency and Sustainability at Gudrunstrasse II

Summary

The quartier rehabilitation area "Gudrunstrasse II" is a typical "historically grown" quarter, which contains buildings from the “Gründerzeit” as well as buildings from all generations of the post-war period. Thus, this project is representative of numerous other residential areas in Vienna, which are structured in the same way. The quartier rehabilitation area comprises a total of 118 buildings, the construction of which is largely in need of refurbishment. An estimate of the final energy consumption and CO2-emissions of the Gudrunstraße II area for room heating and domestic hot water use for the different construction epochs shows that thermal energy consumption currently exceeds 35 GWh/a. As the supply is mainly provided by decentralized natural gas heating systems, this leads to annual CO2-emissions of 12,000 tones. A first estimate shows a theoretical energy saving potential through comprehensive renovations of more than 80 %. At the moment, however, there are no tried-and-tested, holistic model concepts for comparably large building projects with well over 100 typical apartment buildings in order to implement energy-efficient, socially and environmentally friendly renovations within a reasonable time frame. In the present project, therefore, the fields of action "Energy Supply & Utilization", "Inventory & New Buildings", "Urban Ecology & Climate Change Adaptation" as well as "Communication & Networking" are addressed and treated intensively. As part of the project, a demonstration building will be implemented as a lighthouse-refurbishment, whereby a world-wide first demonstrator for the simultaneous material and thermal utilization of greywater will be used. As part of a pilot experiment, an energy community will be set up for the first time, which can exchange self-generated energy among its memebers. In addition, a participatory planning process will be held with residents and relevant actors to develop a masterplan for measures for the area.
