The new "FLAIR in the City" development in the south of Vienna impresses with its many qualities in terms of climate resilience, sustainability and feel-good comfort. The project, which comprises just under 10,000 m² of usable living space, ranges from single houses to terraced "city villas" and apartments. On the roof, there is also a pool, urban gardening and communal areas for all residents.

Sustainable planning right from the start with blue.sprint

Special emphasis was placed on ecological building materials, sophisticated building physics and sustainability as early as the BIM-based planning phase. Six years ago, long before the topic of climate protection was as relevant and present in the public eye as it is today, an innovative and sustainable project concept was developed by the developer FLAIR together with GREEN4CITIES. Xella's digital service blue.sprint was used for this. Planning in blue.sprint can save a considerable amount of the shell construction time and costs of a building project. In addition, waste resulting from planning errors can also be avoided. In cooperation with GREENpass, the developer also carried out extensive simulations with other programms in six subject areas - climate, water, air, biodiversity, energy and costs - and thus achieved greatly improved results - an effective contribution to climate change adaptation.
For this concept, the "GREENpass Gold Certificate" was awarded for the first time in Austria. This is an award given for particularly ecologically and climatically planned sustainability, which also takes into account, in particular, the summer heating of the buildings and their surroundings. In addition, the high level of planning effort and the use of ecological building materials were recognized by the "klimaaktiv Bronze" award from the Austrian Federal Ministry for Environmental Affairs. The project and the effort from all parties involved was also awarded by us with the Xella eXcellence Award for Special Achievements in Housing Quality and Climate Protection.

Xella products make their contribution

The solid building materials Ytong and Silka, which were used in the multi-award-winning residential complex, played a significant role in this. While highly insulating Ytong autoclaved aerated concrete was used for the city villas, Silka was chosen for the up to seven-story residential buildings. For the first time in Austria, Silka calcium silicate blocks were used for the construction of the exterior walls of the apartments. Where statically possible, reinforced concrete was replaced by Silka. In addition to the general ecological and structural-physical properties, the decisive factor for the use of Silka as partition walls for apartments was the lower cost of erection in comparison with formed reinforced concrete walls.
