FAQ

The obligated parties have a certain degree of freedom in their choice of energy efficiency measures. In order to guide their services, they can achieve energy savings either through standardised measures or specific measures. The standardised measures set out different example cases and set flat-rate energy saving values for the following families of measures:

•  Thermal envelope of buildings (walls, windows, roofs, slabs)
• Heat production
• Mechanical ventilation
• Household appliances
• Office equipment
• Lighting
• Transversal industrial techniques (motors, pumps, ventilation, compressed air, boilers, refrigeration)
• Management energy
• Transport (replacement of cars).

Energy efficiency measures not included in the catalogue of measures are to be considered as specific measures, which cannot be accounted for by the obligated parties in case of certain calculation principles and if no standardised measures are applicable.

In order to claim for energy efficiency measures, the obligated parties must demonstrate that they have played an incentive role in carrying out the measures. This means that they must support the consumer who carries out the measure in question with a direct contribution. For example, this incentive might take the form of advice, technical support or a financial contribution. These incentives must be provided before the consumer orders the measure in question.

The obligated parties are electricity and natural gas suppliers active in Luxembourg.
Please check the website of the Luxembourg Regulatory Institute for a complete list of these suppliers.

To initiate energy efficiency measures, the obligated parties are free to act themselves or to use third party implementers.

In principle, the energy savings that can be accounted for by the obligated parties can be in any energy carrier, including fuels, oil, natural gas and electricity.

In principle, all energy consumers are affected, whether households, businesses or the public sector.

The implementation of this obligation mechanism was born out of the desire to achieve the objectives set out in the national energy policy on energy efficiency more effectively.

This measure allows the obligated parties to seize the opportunity to expand their business models and offer energy services to consumers. The experiences of other EU Member States that have already implemented such a mechanism have shown that this approach, based on sound regulation, makes possible the subsequent deployment of energy efficiency measures.
