According to the new Energy Efficiency Directive 2012/27/UE, which will enter into force on December 4th 2012, corporations should be subject to an energy audit performed by qualified experts before December 5th 2015.
The Directive is designed to give a boost to the goal of reducing 20% of energy consumption by 2020. Among its provisions, it is established that large corporations shall perform an energy audit that includes a diagnosis on energy usage by each entity, the sources of energy waste and the technical and economic feasibility of any improvements proposed. The audit will be repeated every 4 years.
Further, the Directive provides, among other things, annual obligations of efficiency both for public buildings and utilities of electricity and gas, and the promotion of ESCOs (companies that provide energy services), especially in the renewable energy sector.
