Size geothermal energy from the design stage.
WellDoneDrill provides the preliminary geological study you need to integrate geothermal energy into your projects from the concept stage in Luxembourg — with no risk of unkept promises, and with the technical documents for your permit application.
EPC A with no architectural compromise.
NZEB regulations impose ever stricter energy-performance levels for every new permit in Luxembourg. Closed-loop geothermal is the only solution that systematically reaches EPC A — with no visible outdoor unit, no thermal constraint on the façade and no noise.

Six good reasons to integrate geothermal energy into your projects.
EPC A with no architectural compromise
Closed-loop geothermal creates no visual constraint. No outdoor unit, no thermal impact on the façade. Your architectural choices remain intact.
Free preliminary study at concept stage
WDD carries out the subsurface analysis of your projects from the concept stage. You know whether it is feasible before integrating it into your brief.
Documentation for permits and EPC
We provide the technical documents in the format expected by Luxembourg's Environment Administration — ready to integrate directly into your EPC calculation note.
Precise sizing, no surprises
Our geological modelling determines exactly the depth and number of boreholes needed. Minimised ground footprint, controlled schedule.
Dedicated technical contact
A WDD engineer follows your project from concept design to handover. Available for your questions, your safety coordinators and your MEP engineers.
Native MEP engineering coordination
WDD works regularly with thermal and MEP engineering offices in the Grand Duchy. We provide the geological data and the sizing; the engineering office integrates the heat pump and the network.
