The main focus of Energy Efficiency Centre is strategic energy planning and policy makers support, which is primarily oriented to fields of energy efficiency, RES, reduction of GHG emissions and reduction of air pollutants. We provide expert support for Ministries in the preparation of strategic and action documents in the fields of energy climate policy and policies on the reduction of air pollutant emissions by developing complex model tools for analysis and projections of energy consumption and emission development. Our centre is the key actor for the development, collection and transfer of knowledge about efficient resource management at the intersection of energy consumers, state, energy providers, equipment and services providers, and other stakeholders due to our holistic approach including energy, environmental and business aspects of energy consumption and transformation. Cooperation with government institutions in the fields of energy efficiency, energy planning, distributed electricity production, reduction of GHG and air pollutant emissions is one of our most important activities, while we remain firmly connected to industry and other institutions in terms of consulting and training role. Our centre actively participates in numerous European projects and leads EUREM training in Slovenia.
