EFIEES’ purpose is to promote the activities of Companies providing Energy Efficiency Services in the European Union


Energy Efficiency Services

Companies providing Energy Efficiency Services design and implement practical measures to improve their customers’ energy efficiency, based on long-term contracts. Energy efficiency services ensure that improvements in energy consumption will be continuously monitored and kept on the long term, through effective operation and maintenance.

  • Definition ofenergy service’  in Article 2, paragraph 7 of the Energy Efficiency Directive (2012/27/EU):

” The physical benefit, utility or good derived from a combination of energy with energy-efficient technology or with action, which may include the operations, maintenance and control necessary to deliver the service, which is delivered on the basis of a contract and in normal circumstances has proven to result in verifiable and measurable or estimable energy efficiency improvement or primary energy savings”


Energy Performance Contracts (EPCs)

  • Definition of energy performance contracting in Article 2, paragraph 27 of the Energy Efficiency Directive (2012/27/EU)

“A contractual arrangement between the beneficiary and the provider of an energy efficiency improvement measure, verified and monitored during the whole term of the contract, where investments (work, supply or service) in that measure are paid for in relation to a contractually agreed level of energy efficiency improvement or other agreed energy performance criterion, such as financial savings”

  • Definition in the Commission’s 2011 Energy Efficiency Plan:

“Within the context of this form of purchase based on performance, financial savings made from lower distribution service bills and maintenance costs arising from energy efficiency measures are to be used to cover fully or partially the investment costs attached to these measures.”

To learn more about the fundamental principles for a successful and transparent EPC, take a look at the EPC Code of Conduct, which was developed as part of the Transparense project.


District Approach for Heating and Cooling

  • Definition of ‘district heating’ or ‘district cooling’ in Article 2 of the Renewable Energy Directive (2009/28/EC):

“the distribution of thermal energy in the form of steam, hot water or chilled liquids, from a central source of production through a network to multiple buildings or sites, for the use of space or process heating or cooling”

  • Definition of ‘efficient district heating and cooling’ in Article 2 of the Energy Efficiency Directive (2012/27/EU):

“a district heating or cooling system using at least 50 % renewable energy, 50 % waste heat, 75 % cogenerated heat or 50 % of a combination of such energy and heat”
