Energy performance certificate or EPC is the energy indicator of a building that certifies the energy needs. The EPC is mandatory for new buildings, for existing buildings, if a renovation was made and for existing buildings, if a rental/sale was made. The duration of energy performance certificates is 10 years.

Thermography, a.k.a. infrared is the technique that permits to obtain a thermal image (called thermographic) of an observed scene in the infrared, using an appropriate equipment, the thermographic camera. This technique is particularly used on building’s surveillance to locate defaults, that could exist on the building envelope. The defaults (thermal bridges) are sometimes created on exterior walls which constitute the building’s envelope (construction part which separates exterior from interior) which can lead to considerable heat losses.This,combined with building degradation, due to condensation appearance, results to thermal comfort disappearance on building interior.

Blower door test allows measuring the building’s air infiltrations by the envelope’s defaults (exterior walls-roof-floor and frames). For this test, the necessary equipment is called “blower door” which permits to create differential pressure between exterior and interior (50 Pa) in order to measure the airflow under these conditions, either to obtain an air tightness label, either to determine the building’s envelope defaults. Air defaults localisation on building envelopes is achieved by infrared camera or by smoke generation.

Energy consultation are all the actions that are proposed to the owner of building by the energy consultant, targeting the building’s energy efficiency improvement, proposing envelope renovation measures, modifications and proposals of technical installations in a rentable and alternative point of view.

Energy consulting, to be performed as part of energy sanitation of an existing house, must be in the form of a conclusive report, established by the energy consultant. This report must include a comprehensive inventory of the object in question and generate a complete energy sanitation concept.

According to the Grand Duchy regulation of 12 December 2012, an aid scheme to promote the rational use of energy and the development of renewable energy in the housing field is applied. The conditions and the areas of State aid contained in the following link
