As certified energy advisors (Klima-Agence certified), we provide expert guidance to ensure your building or renovation project is energy-efficient and future-proof. Our range of services includes :

Tailor-made Sustainable Energy Concepts

How build a house that consumes less energy? What alternatives to fossil fuels should you choose to heat your home ecologically and economically? What physical building materials can I use to improve my quality of life and reduce my energy costs? As part of the construction planning process, we draw up a tailor-made energy concept for your building project and look for optimal solutions for more rational and sustainable energy use. Whether it's a new build or a renovation, we can help you find the most energy-efficient solution for your building project. 

Energy Performance Certificate for Buildings (Energy Passport)

We draw up energy passports or, more precisely, certificates relating to the overall energy performance of buildings. The energy passport is a quality label prescribed by law that informs consumers about the energy efficiency of residential buildings, enabling them to compare them with other residential buildings. The government does not subsidise the production of an energy passport. It is valid for 10 years from the date of issue. Detailed information is available on the Klima-Agence website: https://www.klima-agence.lu/en/energy-epc

Energy Renovation Advice

How can I make the most of the architecture of my home while renovating it in a way that is optimal from the point of view of building physics and energy? How can I significantly reduce energy consumption and improve my sense of well-being? We look for tailor-made solutions to bring your renovation project to fruition through well-thought-out architectural solutions.

Help with Applications for State Financial Aid

Every building project is unique. Only a global approach, combining technical, aesthetic, physical and energy aspects, is the key to a comfortable and sustainable living experience. With Klima-Agence, the Luxembourg government is providing a system of financial aid for the construction of sustainable housing and sustainable energy renovation. As certified energy advisors, we have the expertise to guide you through the maze of subsidies for sustainable construction and renovation.

Energy Consultants (Klima-Agence certified)

We are certified energy consultants (Klima-Agence certified). This is the official state quality label for energy consultancy, sustainable construction and energy-efficient renovation. We advise our customers on energy efficiency and the sustainability of buildings, and support them in their sustainable renovation projects through certified craftsmen. However, we only do this in the context of construction or renovation projects, which we carry out from the planning stage through to implementation. Detailed information on the subject of energy advisors is available on the Klima-Agence website https://klima-agence.lu/en/certified

LENOZ Certificate

To promote sustainable construction, the Luxembourg government has created LENOZ certification for residential property, a voluntary initiative for building owners. LENOZ stands for ‘Lëtzebuerger Nohaltegkeets-Zertifikat fir Wunngebaier’. Under this scheme, the building is assessed beyond the energy performance certified by the Energiepass, in particular with regard to: the environmental assessment of building materials; health, indoor and outdoor air quality and comfort; and the choice of location. Detailed information on the LENOZ certificate is available on the Agence du climat website: https://klima-agence.lu/en/lenoz-certificate-0
