EU regulations on building energy performance and refrigerant phase-down will require European hotel operators to replace or upgrade air conditioning systems in the coming years, with the strictest rules taking effect by 2030.

The revised Energy Performance of Buildings Directive (EPBD), agreed in March 2023, sets a binding trajectory: all new buildings must be zero-emission by 2030, and new public buildings by 2028. For existing non-residential stock — which includes hotels — member states must establish minimum energy performance standards that progressively tighten the worst-performing buildings through 2030 and 2033.

A separate F-gas regulation, adopted in 2024, accelerates the phase-down of hydrofluorocarbon refrigerants used in commercial cooling. Many hotel chiller and split-system units rely on R-410A (global warming potential 2,088) or R-134a, both facing earlier quota cuts.

What does the EPBD require of hotels?

The directive sets a December 2025 deadline for member states to publish national renovation plans, and May 2026 to transpose the rules into national law. From 2027, new buildings must rely on heat-pump or renewable-based HVAC where fossil-fuel systems were previously standard, subject to technical and economic feasibility tests.

The non-residential renovation obligation targets buildings with the lowest EPC ratings, typically older independent properties and aging chain assets in southern Europe. Hotels using gas boilers for heating face the additional pressure of the EPBD fossil-fuel phase-out, which requires member states to end fossil-fuel use in existing buildings by 2040.

How will the rules affect hotel operating costs?

The immediate cost is capital. Replacing a chiller or VRF system in a mid-sized European hotel typically runs €200,000 to €1.5 million depending on capacity, climate zone, and installation complexity. Heat-pump HVAC systems cost more upfront but cut electricity consumption for cooling and heating by 30-50% compared with conventional split systems paired with gas boilers.

Hotels in southern Europe spend 6-10% of operating costs on energy, according to industry benchmarks, with cooling the largest share in Mediterranean markets. Energy-efficient HVAC can reduce cooling-related consumption by 20-40%, depending on building envelope, controls, and climate.

Which refrigerants are at risk?

The F-gas regulation sets GWP thresholds for new commercial cooling equipment, with limits of 750 for fixed air conditioning and tighter limits for smaller split systems. R-410A, used in most post-2010 VRF installations, does not comply. Operators have two practical paths: R-32 (GWP 675), already standard in many residential and light commercial units, or natural refrigerants such as propane and CO2, which face flammability and pressure restrictions in larger hotel applications.

The servicing market for existing systems is also tightening. Reclaimed and recycled HFCs will increasingly supply maintenance demand, with prices for high-GWP refrigerants expected to rise as quotas fall through 2030 and beyond.

What happens next?

Member states must publish their national building renovation plans by the end of 2025 and transpose the EPBD into national law by May 2026. Hotel operators should expect significant variation in local implementation: subsidy schemes, permitting timelines, and the pace of MEPS enforcement will differ across the EU's 27 member states, complicating portfolio-wide capital planning for chains with assets in multiple markets.

Decisions made in 2025 and 2026 on chiller replacements, heat-pump installations, and refrigerant choices will lock in compliance for the next 15-20 years.
