Klimabonus for hotel tertiary
The Klimabonus scheme (law of 23 December 2022) covers energy retrofits in Luxembourg tertiary buildings. For a hotel, eligible items include insulation, HVAC, LED lighting + BMS, triple-glazed windows, heat pumps and solar thermal. Subsidy rates reach 25-62.5% depending on retrofit scope and performance target, with a CO₂ bonus tied to actual savings.
Tertiary vs residential differences
For tertiary, applications go through the SME Single Window and the Ministry of Economy (not Klima-Agence for individuals). Minimum improvement thresholds (e.g. 30% primary energy gain) condition eligibility. Cost caps are higher (€250-450/m² per item) and an energy audit is systematically required.
ROI: energy savings + RevPAR gain via label
Hotel retrofit profitability combines two effects. First: direct energy savings (20-40% of annual bill after deep retrofit). Second: observed RevPAR gain via eco-label (Green Key, EU Ecolabel, Biosphere) — +1 to +3% ADR per STR and HOTREC studies. The second effect is often the real ROI lever.
Frequently asked questions
Can Klimabonus be combined with other aids?
Yes, with Klimaprêt (0% subsidised loan), regional/communal aids and energy supplier premiums. Combinations are capped at 80-100% of eligible expenses depending on schemes.
Which retrofit item offers the best ROI?
For an existing E/F-rated hotel, roof insulation + heat pump replacement typically offers the fastest ROI (6-10 years). LED + BMS is the most profitable in absolute value if electricity consumption dominates. Windows are profitable only if existing ones are severely degraded.
Does an eco-label actually raise ADR?
STR Global + Cornell Hospitality studies: Green Key or equivalent certified hotels get +2 to +4% ADR vs uncertified competitors, with a 1-2 pt occupancy premium. The effect is stronger on corporate and MICE segments (CSR criteria demanded by corporate clients).
