The calculation of the energy performance and the energy performance certificate for residential and non-residential buildings must be drawn up by:
- compulsory members of the Order of Architects and Consulting Engineers (Ordre des Architectes et des Ingénieurs-Conseils - OAI);
- or natural or legal persons accredited by the Minister of the Economy.
These documents are drawn up following a method of calculation based on:
- the calculated energy needs, in the case of residential buildings and new non-residential buildings;
- the measured energy consumption, in the case of existing non-residential buildings.
Compulsory members of the OAI are allowed to draw up these documents for all types of buildings, whereas persons accredited by the Minister of the Economy may draw up these documents for residential buildings and existing non-residential buildings.
In order to receive accreditation to accomplish technical tasks of study and control in the field of energy, applicants must comply with a certain number of conditions and send an application to the Minister of the Economy.
The Ministry of the Economy offers training courses on the Grand-Ducal regulations on the energy performance of residential and non-residential buildings (LuxEeB training courses).
Experts who have attended these courses appear on the lists of experts published on the Business Portal.
