Multifunktionsfassade

This system was used in practice for the first time as part of the implementation project 'Wohnen findet Stadt!', funded by the Climate and Energy Fund in the "Smart Cities Demo" program. The multi-storey social housing building 'Salzachtalstraße 32-34' in the Burgfriedsiedlung in Hallein was renovated and topped up. In the course of this refurbishment, the existing building was equipped with an external wall heating system, which offers the residents a high level of comfort through radiant heat during operation, but also enabled the most comfortable and stress-free conversion possible due to the minimally invasive intervention. With this renovation option, the residents were able to remain living in the building throughout the renovation work.

The reduced energy consumption amounts to about 50 % compared to the existing situation. The energy for heating and hot water is drawn from the district heating network, which in Hallein is provided 100% from industrial waste heat. A photovoltaic system installed on the roof of the building provides renewable energy, and the construction of the addition and the facade is made of biogenic materials. High sound absorption properties of the façade reduce the sound level in the open space and thus make the open spaces more attractive for the residents. The measures are subjected to an intensive monitoring process in order to be able to further optimize the system with regard to economic and ecological aspects.
