FAQ

In general, it is the owner of the building or the co-ownership management body that submits the request for aid for obtaining a sustainability certificate. 

A developer is therefore eligible for financial aid if, at the time of application, they are the owner of the building (or hold a share of the building). The establishment grant will no longer be available to future owners of lots for which the developer has already received financial aid. 

The amount of the establishment grant is as follows: 

• if the developer is a sole proprietor and if the “vertical land registry” (a descriptive statement on the division of the private lots and the common parts of a building under a co-ownership regime) has not yet been created: establishment grant of €1,500;
• if the developer is the sole owner and if the vertical land registry has been created: establishment grant of €750 per apartment/housing unit without exceeding the actual costs. 

In the case of a property in co-ownership, all co-owners must sign the application form for financial aid for the certificate process. The co-ownership management body can submit the application on behalf of the co-ownership.

The size of the installation must be calculated in accordance with VDI (Association of German Engineers) Guideline 4640. Ask your chosen drilling company for information on this subject.
In addition, you can also have a heat load calculation and a geological survey carried out in order to establish the sizing.

You must ensure that you have obtained all necessary permits before the works start. Contact : forages@eau.etat.lu

The exact date of the start of drilling must then be notified to the water management authority in advance. Ensure that the drilling company and the installer coordinate their schedules.
