FAQ

The indicator I_eco12 represents the environmental impacts (I_env) and the impacts induced by the primary energy requirement (I_prim) of an insulation material, evaluated on an equivalent thickness of 12 cm. This results in an independent environmental assessment of the existing building, while taking into account the grey energy consumed by the insulation material.

To benefit from bonuses within the framework of aid for insulation measures in your home, the following criteria must be met:

• recycling of insulation materials: you can benefit from a 50% recycling bonus if at least 50% of your fossil or mineral insulation material is made from recycled raw materials. The 50% recycling bonus for fossil insulation materials is only valid until 31.12.2023.
• criteria for green insulation materials: you can receive a 50% FSC/PEFC/SFI bonus if your green insulation material is made from FSC/PEFC/SFI certified raw material

Since 1 January 2017 (date of the energy consultant's invoice), thermal insulation must meet energy efficiency and durability criteria. The energy efficiency criteria correspond in substance to those of the previous PRIMe House scheme and are expressed in four energy performance standards.

The durability criteria refer to the environmental quality and nature of the thermal insulation, as well as the way in which it is attached.

Environmental quality is defined by the environmental impact of insulation materials assessed using the environmental indicator I_eco12.

The approved energy adviser is responsible for:

• carrying out on-site energy consulting;
• drafting the "conclusive report" (a comprehensive inventory of the property in question, the content of which must include a description of the property, the date of the site visit, the energy performance certificate prior to the retrofit and an integral energy renovation concept);
• checking the conformity of the offers to the measures proposed in the above-mentioned energy retrofitting concept;
• checking the conformity of the implementation on site with the measures proposed in the energy retrofitting concept;
• drafting a final report that must be attached to the request for payment of financial aid; 
• completing the forms for the request for an agreement in principle and for the payment of financial aid.

The quality assurance system for approved energy advisers within the meaning of the Klimabonus subsidy scheme includes the following:

• verification of the basic qualifications of the energy adviser;
• verification of any additional qualifications of the energy adviser;
• checking and approval, prior to certification, of an energy consultation report for a retrofitting project;
• a timely and regular quality control system, including: 
  • quality control of the services provided by energy advisers;
  • checking compliance with the conditions associated with the ongoing training of energy advisers, and
  • implementation of a customer evaluation system.

Since January 2017, energy advisers have been able to obtain certification by submitting an approval application to the Environmental Administration. Approval is conditional on membership of the OAI (architect or engineer in accordance with the Law of 13 December 1989) or an authorisation in accordance with the Grand Ducal Regulation of 10 February 1999 on the approval of natural or legal persons, private or public, other than the State, for the performance of technical study and control tasks in the field of energy, as amended.

From 15 December 2018, approved energy advisers will have to join a quality assurance system in the field of energy and sustainability consultancy for residential buildings with a body contracted for this purpose by the Ministry of Sustainable Development and Infrastructure. 

Benefit from financial support of up to 50% of the investment cost!

Under Article 4(h) of the Law of 31 May 1999, as amended, establishing a fund for the protection of the environmental, municipal administrations, municipal associations and public bodies under the supervision of the municipalities may receive aid covering up to 50% of the investment cost for projects for the rational use of energy and the promotion of new and renewable energy sources. This financial aid is accessible to all municipalities, regardless of their commitment to the climate pact.

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.
