Penzing district, Vienna, Austria

A project within Eu-GUGLE.

Vienna is the capital of Austria situated close to Hungary. The EU-GUGLE district is named Penzing or the 14th district. The smart Viennese gate to western Austria and to the Natura 2000 area, the Biosphärenpark Wienerwald, covers about 3,374 hectares with a share of 60% on open space including parts of the forest surrounding Vienna.

All envisaged demonstration buildings have poor energy performance values and urgently need the foreseen renovation. The main focuses are the efficient refurbishments of around 62,546m² gross floor area with prefabricated façade elements, the intelligent integration of renewable energy in buildings and realisation of suitable accompanying measures to create a high-quality city district.

The district and the building stock

The district has about 84,362 inhabitants. Citizens in the age between 40 and 50 years are dominant.

All envisaged private buildings serve as viable space for tackling the different flat ownerships that exist in Vienna. Special appointments with “house representatives” will be organized to countercheck baseline data of the social housing company Wiener Wohnen and other partners, as well as to map building particularities during the preparation phase of the realisation.

The demonstration buildings serve for residential purposes and have been built in between 1952 – 1972. They have 4 – 5 residential floors, mostly with staircases only, and are built as rectangulars.

  • 62,546m² gross floor area surface to be renovated.
  • 3592 inhabitants in the renovated buildings.
  • 1038 dwellings to be renovated.

The buildings within the district are residential buildings and social housing, owned by tenants and flat owners.


The expected energy efficiency savings are about 55-65%.

During the project, data of planning and implementation details will be collected to provide information about building physics, refurbishments and HVAC of the realized demonstration objects. Monitoring data will also be collected, in order to compare measured results with calculated yields.

In order to figure out interactions of energy-related consumer behaviour and to point out lessons towards how to apply consumer-oriented strategies more effectively, interviews will be performed with selected end-users.
