Yes, the EPC training courses developed by the Ministry are open to everyone, including municipal employees. They can be booked on the Internet portal www.guichet.lu/experts-energie. In addition, in 2017 a workshop was organised on the subject of site inspections led jointly by the Ministry of the Economy, Klima-Agence and Syvicol. Klima-Agence is also prepared to strengthen its collaboration with the municipalities. If necessary, the municipality can contact the qualified adviser at Klima-Agence. Some additional EPC training courses are also available on the main Luxembourg training portals.

The deviations must be documented and the main contractor must be notified of them. The municipality has the right to request additional calculations and/or documentation. The "as built” EPC indicates whether the minimum requirements have been met despite the deviations once the building is completed. As with any non-compliance with the building permit, the municipality can demand that the construction work required to ensure compliance with the EPC be carried out during the construction period and call the police if necessary.

It is not mandatory to carry out inspections of building sites. However, the municipality has the right to go to the building site and check the construction work to check that it complies with the energy performance certificate.

The municipality has the right to request the "as built" EPC from the main contractor. Other measures may also be envisaged, for example the introduction of a deposit system. According to one Grand Ducal Regulation, municipalities even have the possibility of prosecuting the main contractor (sanctions enshrined in the Law of 5 August 1993 on the rational use of energy, as amended).

The municipality can itself decide on the consequences to be imposed on the main contractor/planner/construction company in the event of a breach of the legal requirements. In principle, a breach of these obligations can be treated in the same way as a breach of the distance rules or surface area coefficients.

It is mandatory to present the “as built” EPC for all new buildings, extensions and modifications to existing buildings. It must be presented within two months of the start of use or final acceptance of the building. The building must continue to meet the energy requirements.

The "as built” EPC is issued once construction of the building has been completed. All deviations from the planning phase that have an effect on energy efficiency are recorded in the "as built" EPC.

The feasibility study provides information on the possibility of using renewable energy in a new building. A feasibility study is mandatory for all new buildings.

According to Article 3 of the Grand Ducal Regulation of 30 November 2007 on the energy performance of residential buildings, as amended, and Article 4 of the Grand Ducal Regulation of 31 August 2010 on the energy performance of non-residential buildings, as amended, a building permit can be issued only if the EPC is complete and the minimum and general energy efficiency requirements contained therein are met. This applies to residential and non-residential buildings alike.
