Sustainable energy efficiency through local solutions – sulphur dioxide and particulate emissions down by 70%

In densely built residential areas, it is worth generating renewable energy at local level. A report by VTT shows that this increases energy efficiency and sustainable housing construction, and leads to the production of ecological and optimally self-sufficient energy solutions. Seasonal thermal energy storage (or STES) can markedly reduce emissions from the heating of localbuildings. All new buildings must be close to the level of zero-energy buildings by late 2020. The related challenges lie in the potential uses of renewable energy and achieving greater energy efficiency in new
