The ChangeBest project was implemented for contributing to the development and implementation of the Directive on energy end-use efficiency and energy services (ESD), whose main objective is to stimulate the market for energy services and the delivery of other energy efficiency improvement measures to final consumers. In order to achieve this objective, the ESD gives a special role to energy distributors, distribution system operators and retail energy sales companies.

On the other hand, there are different types of energy service companies (ESCOs) in the market ready to expand their business in the field of energy efficiency services. Against this background the ChangeBest project tried to understand how and to which extent the EES market could be further developed, what are appropriate business strategies and promising services not only for “advanced” companies but also for “beginners”, what is a policy framework suitable to stimulate market development and to overcome existing barriers, and what role energy companies developing towards sustainable ESCOs could play.


  • to assist energy companies and ESCOs in entering the B2B and B2C market for energy efficiency services (EES);
  • to contribute to the EES market growth as part of the implementation of the ESD, in particular developing “new” EES;
  • to demonstrate good practice in implementing the ESD.
