More detailed information:

objective +

An energy consulting will make it possible to intelligently improve the thermal and energy quality of your building.

The various possibilities for improvement can subsequently be realized by the specific companies  in order to reduce energy losses, in particular heating, in order to achieve significant savings.

contents +

A comprehensive and detailed report is crated after a site visit and an analysis of the building. The study verifies all construction elements such as walls, windows, ceilings and roofs in order to propose concrete measures to improve the quality and comfort of the building.

advantages +

Improving energy quality means saving money in the long term, respecting the environment and improving the health of your building, reducing the risk of thermal bridges and molds.

grants +

As part of an energy renovation, the Luxembourg government is proposing a financial aid of 70 € per hour for the realization of an energy consultancy drawn up by an expert, without however exceeding the following ceilings:

  • single family house = 1000 €
  • multi-family dwelling = 1200 € / 2 dwellings, 25 € / additional flat, ≤ 1600 €

A maximum of € 150 is granted for energy consultancy in the following technologies: solar heating, photovoltaic, wood heating, heat pump, condensing boiler, micro-cogeneration, urban heating.

Additional subsidies can be obtained if the house is more than 10 years old. Renovated building elements must not exceed the minimal energy values given below:
