Many applications of the ESCO model include installation of new efficient equipment, automatisation, energy systems optimisation and application of renewable sources of energy in the already existing facilities, which thus makes the clients very diverse. Potential projects can be feasible in industrial facilities, business premises, logistics centres, shopping malls, etc. There are wide opportunities of energy efficiency improvement in the public sector, e.g. in public lighting, hospitals, schools, nursery schools, care homes, etc.
