The World Energy Efficiency Day is held every year on 5 March.
Energy efficiency is considered a source of energy in itself. This analogy is today fully accepted, and energy efficiency has been recognised as a priority area due to the lack of energy resources, the dependence on importing energy and the need to mitigate the climate change.
Different technical standards provide the tools required to reach the energy efficiency goals. Some key standards are already broadly recognized, such as standard UNE-EN ISO 50001, which establishes the requirements for an energy management system, the series of UNE-EN 16247 standards that define guidelines for energy audits, or UNE 216701 which establishes a classification and categorization of the position of energy service provider. In the coming months new initiatives of this kind are expected, such as the revision of standard UNE-EN 16325 on guarantees of origin related to energy or the development of a European standard on energy performance contracts.
In the face of global challenges, such as the lack of sources of energy sources, establishing criteria agreed by all the interested parties helps implement viable, effective and comparable energy efficiency measures.
