We are a voluntary NGO, created to facilitate the promotion of energy efficient principles among member municipalities. Our focus is upon transforming local economies into sustainable communities with an emphasis on information, exchange of useful ideas and experience, new technologies and managerial know-how in resource allocation. We build relationships with key stakeholders on a local level to help communities achieve energy security, preserve the environment, improve local quality of life and continue along the path of true sustainable development. The inception of the idea to form an association took place within the Monitoring of Energy Performance of Public Buildings in Ukraine project (2004-2006). The project was financed by the European Comission within the framework of the Partnership Programme for Institutional Developement (Tacis, IBPP).
