The implementation of the EU 2020 energy and climate targets triggered the transformation of Europe’s neighbourhoods to net-zero energy districts. Frontrunner municipalities have set ambitious targets to reduce their energy demand and to increase the share of their energy supply from local renewable energy sources. European municipalities set their energy targets in different ways and the timeline to meet the agreed target at a local level varies from one municipality to another. Hvar, the remote Croatian Island, as well as the municipality of Val-de-Ruz, in Switzerland, have set a target to be self-sufficient. However, the former aims at meeting its self-sufficiency target to be 20% by 2020 while the latter aims to be totally self-sufficient by 2030. Similarly, the municipality of Helsingor in Denmark aims for carbon neutrality by 2050 while Cloughjordan in Ireland aimed at building an eco-village in a rural area. Other municipalities such as Salzburg in Austria developed a 2050 smart city roadmap while Valby in Denmark set a renewable energy target and the municipality of Zaragoza in Spain developed and implemented a holistic bioclimatic design at neighbourhood level. The definition of the target and the timeline to achieve the agreed target influence the selection of measures and sectors to consider. Importantly, making buildings highly energy efficient is a common component in each of the 61 identified European projects. However, in order to meet their energy targets, less than 50% of the identified projects considered both the renovation of existing buildings and the construction of new buildings to low-energy consumption standards. Additionally, data on the achieved energy consumption and the supply from renewables in the use phase as well as investment data were identified only for seven projects.
