act2, ‘Action to mainstream efficient building and renewable energy systems at a city level across Europe’ has the underlining rational of “cities willing to improve the quality of life and adapt their infrastructures to the sustainable energy model ruling the present century”. Hannover in Germany and Nantes in France are the two CONCERTO demonstration cities in the act2 project. The act2 project builds on previous experience gained from the Hannover community project and other European city projects. The project supports the development of a similar strategy in Nantes and analyses the drivers for success in partner cities like Malmö, Koszalin and Newcastle, which are co-operating, as observers.
act2 aims and objectives
act2 aims to implement major developments in target communities taking significant steps towards establishing best practice experiences, as a single standard for future commercial practice. In the real estate sector, act2 communities specifically demonstrate technical and process solutions for large-scale energy efficiency (EE) and renewable energy source (RES) integration in new build and refurbishment projects, in housing and public buildings, and providing a benchmark for the Cities of Tomorrow.
act2 – focus areas
act2 implements a range of varying techniques for increasing the use of renewable energy sources (RES) and stresses the importance of the use of RES as the primary solution for decentralised energy grids within the supply menu.
act2 retrofitted buildings in Hannover are connected to district heating from Combined Heat and Power (CHP) systems, while eco-buildings are equipped with wood pellet heating systems. Energy saving advice service for users and tenants and campaigns promoting the activities and convince other house owners from the CONCERTO demonstration communities are carried out.

act2 – research activities
act2 research activities have two focus areas:
1. Identification of hurdles and drivers for the implementation of energy efficiency (EE) measure and renewable energy sources (RES) on the community level (including analysis of all relevant actors and containing relevant socio-economic aspects)
2. Analysis and evaluation of new forms of design, planning, construction processes to realise ambitious energy objectives under economically compatible conditions (to provide know-how transfer of new energy concepts on large scale on the local community level)
act2 aims to produce results which lead to a better understanding of the range of barriers and provide detailed know-how which can be transferred from the most experienced participant communities to the ones with less experience.
