6. EFEM – some results and conclusions The project is co-funded by the European Union, the Russian Federation and the Republic of Finland Some differences between Russian and Finnish heating systems were identified. Holistic approach is needed to assess the energy efficiency potential of larger districts and regions. Further research is needed to explore the energy efficiency potential in St. Petersburg. Shared experiences can contribute to energy efficiency in Russia and Finland.
