The objective was to achieve 40 to 80% primary energy savings per pilot district while increasing the share of renewable energy sources by 25% by 2018. To reach this objective, the 8 pilot cities joined efforts to combine the latest research results relevant to the smart renovation of groups of buildings at the district level and use this knowledge to implement a balanced mix of technical, socio-economic, and financial solutions adapted to local needs. The EU-GUGLE project aimed to demonstrate the feasibility of nearly-zero energy building renovation models in view of triggering large-scale, Europe-wide replication in smart cities and communities by 2020. Taking on the challenge of sustainable renovation in urban areas, the cities of Vienna (AT), Aachen (DE), Milan (IT), Sestao (ES), Tampere (FI) and Bratislava (SK) have committed to renovating a total of 226,000m² of living space during the 5 years of the project.

The EU-GUGLE district is named Penzing or the 14th district. All envisaged demonstration buildings have poor energy performance values and urgently needed the foreseen renovation. The main focuses were 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.
