EU-GUGLE Site Vienna
The EU-GUGLE demonstration district in Vienna 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.
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.
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 building stock which will be renovated consists of 1038 dwellings with 3592 inhabitants. The buildings in the district are residential buildings and social housing, they are owned by tenants and flat owners.
The demonstrations will use several innovative integration measures and enabling technologies such as:
- Decentralised ventilation
- Smart metering
- Integration of CH4 produced by renewables
- Building Integrated PV (BIPV)
- Solar thermal
- Replacement of decentralised fossil heating systems by centralised renewable heating plants
- Symbiotic integration of green power marketing
- Socio-economic evaluation
- Participatory action research
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.
