No, the vehicle must have been ordered (date of the sales contract) between 11 May 2020 and 31 March 2022. The vehicle must be put into circulation for the first time by 31 December 2021 at the latest and must not yet have been registered abroad.

However, for vehicles ordered before 11 May 2020 and put into circulation in Luxembourg for the first time between 1 January 2019 and 31 December 2022, and which have not yet been registered abroad, the €5,000 grant continues to apply.

The Zero emission vehicles purchased between 1 April 2021 and 31 March 2022 that are eligible for a €8,000 grant are as follows:

•    a new passenger car (electrical energy consumption** ≤ 18 kWh/100 km) new 100% electric
•    a new large family car*** (electrical energy consumption** > 18 kWh/100 km and vehicle ⩾ 7 seats) new 100% electric
•    a new 100% electric van
•    a new hydrogen fuel cell passenger car or van;

**The electrical energy consumption is included either in the Community certificate of conformity or in another equivalent certificate issued by the vehicle manufacturer or its authorised representative and recorded in the national road vehicle database.

***The vehicle must have at least seven seats, including the driver's seat, and the applicant for aid must be a natural person forming part of a household of at least five persons.

In principle, a wall does not breathe. Air renewal and moisture removal are only achieved by ventilation (via windows or the installation of comfort ventilation, i.e. controlled mechanical ventilation – CMV). The effect of 'breathing' as mentioned above refers to the transfer of moisture by the diffusion of water vapour. In practice, this is minimal and does not play any role in moisture removal. On the other hand, it is important for interior plaster to be able to absorb moisture from the air and release it back into the interior after ventilation. The effect of moisture regulation effect therefore only operates within the first few centimetres (on the interior side) of a wall. For example, clay plaster on internal walls provides excellent moisture regulation.

Joints can cause significant heat loss. In winter, warm, moist air escapes to the outside via areas that are not tightly sealed, i.e. joints and cracks. This leads to the air cooling down and humidity condensing, which can give rise to the formation of mould in the recesses. In order to detect heat loss, thermal imaging is recommended.

An energy retrofit of a building (insulating the façade and roof, as well as replacing the windows) seals the building more tightly and can thus improve energy performance.

Buildings constructed between 1900 and 1970 have enormous potential for energy retrofitting. To find out the energy performance of your building’s insulation, it is necessary to analyse each project individually. Klima-Agence offers you a free energy diagnosis to check the state of your home's insulation.

Insulating materials are not all flammable. Insulating materials are divided into different fire protection categories. A European standard regulates the classification of materials and building types according to their fire behaviour.
In principle, insulating materials made out of minerals are non-flammable. They are taken into account in the Luxembourg sustainable housing certification (LENOZ) framework and can thus receive state financing as part of an overall concept. This also applies to retrofits: choosing insulating materials of mineral origin makes it possible to obtain higher financing compared to conventional materials.

Some materials used as façade coverings may be flammable. This is why it is important to take into account the overall make-up of the external wall. However, this may also include flame retardants (i.e. sealant, firewall, etc.) and thus provide protection against the spread of flames.

Insulation is one of the most important measures to take when boosting the energy efficiency of a building. No other measure can save as much energy for heating. 

Manufacturing the insulating materials consumes much less energy than the materials ultimately save. The energy used to manufacture insulation materials is marginal compared to the energy saved in a dwelling over a period of 20 to 30 years. As such, the energy consumed in manufacturing insulation does not constitute an argument against energy retrofitting, but it can very well influence the choice of insulating material. According to Klimabonus State aid criteria, environmentally friendly insulation requires little energy to produce.

The Klimabonus programme provides substantial subsidies for the use of environmentally friendly insulation.
