Description
The Act2 project aimed to accelerate innovation in renewable energy (RE) solutions and advance energy efficiency (EE) and systems for poly-generation linked together with concepts for eco-buildings. Act2 reflected the motivation of Hannover (Germany) and Nantes (France), the two demonstration communities, and three associated cities – Koszalin (Poland), Malmö (Sweden) and Newcastle upon Tyne (United Kingdom) - to implement an energy policy that matches the scale and urgency of current climate-related issues, building on past experiences - especially the development of the Kronsberg district in Hannover, and inviting stakeholders in their areas to espouse the same proactive policies.
