The project focuses on analyses in the field of energy efficiency and energy savings and aims to contribute to informed decision-making. The project includes modelling of energy consumption, evaluation of energy efficiency as such and energy efficiency measures and other partial analyses in the field of energy efficiency and climate change, including energy poverty and financing. The main contribution of the project will be the analyses, which can serve as a basis for preparation of the policy in the field of energy efficiency and climate change, including strategic, conceptual and planning documents, as well as financial mechanisms in Slovakia and abroad. The project will also contribute to improvement of the methodology in the field of energy use modelling, as well as in the evaluation of energy efficiency and energy poverty. The focus of the project has an impact also on many other areas, especially in the area of climate change, as well as in the socio-economic area.
