The environmental constraint: a cost that sorts assets

7.1 — Layered regulation, and what it actually targets

In France, the environmental transition of buildings has produced a stack of overlapping rules. Their exact scope must be established first, because confusion on this point leads to overstating some constraints and understating others.

Three instruments apply directly to hotels. The Éco Énergie Tertiaire scheme, commonly called the tertiary-sector energy decree, requires commercial buildings of at least 1,000 m^² (hotels are explicitly included) to cut final energy consumption by 40% by 2030, 50% by 2040 and 60% by 2050, relative to a reference year chosen between 2010 and 2022, or to meet absolute thresholds set by activity. Compliance runs through an annual declaration of consumption on the OPERAT platform of ADEME (the French agency for ecological transition); the filing deadline is annual, on September 30.^¹⁹⁴ The BACS decree requires a building automation and control system (a building management system) depending on the rated output of heating, ventilation and air-conditioning equipment. The obligation has applied since January 1, 2025 above 290 kW. For the 70–290 kW band, a December 2025 decree pushed the deadline back from January 1, 2027 to January 1, 2030, to align France with the revised EU directive.^¹⁹⁵ Finally, the mandatory energy audit, required every four years, used to target large companies; with the transposition of the EU Energy Efficiency Directive, it is switching to a criterion of consumption above 2.75 GWh per year.^¹⁹⁶

Where does the building stock stand? Declarations are rising; the two available measures, which are not on the same basis, do not show whether the filing backlog is clearing. As of January 31, 2024, 19% of the 291,486 registered entities subject to the rule had filed no consumption declaration. Two years later, ADEME counts nearly 340,000 declared entities, while roughly one-third of the stock subject to the rule remains uncovered (at the current pace, full coverage would come only around 2031). ADEME measures a 26% decline in climate-adjusted final energy consumption and notes that nearly half of the floor area already declared has met one of the two targets set for 2030. That figure does not hold for hotels: health and tourism establishments lag, with slightly under 30% of their floor area already compliant with the 2030 target.^¹⁹⁷ The scheme is therefore not an administrative failure: it produces data, and a measured reduction in consumption across the declared entities, which cannot be attributed to the decree alone. On the BACS decree, by contrast, equipment lags far behind: barely 16% of affected sites had a building management system in 2025.^¹⁹⁸ The French stock is thus making progress on measuring its consumption, much less on the tools needed to manage it.

7.2 — A penalty that works through value, not fines

The most important feature of this framework, and the least understood, is the nature of the penalty. It is almost never financial in the sense of a fine proportionate to the breach.

In case of non-compliance, the tertiary-sector energy decree provides for a formal notice, publication of the offender's name on a government website and an administrative fine capped at €7,500 per building for a legal entity (Decree No. 2019-771 of July 23, 2019; Articles R. 174-31 et seq. of the Construction and Housing Code). Small relative to both the cost of upgrading and the value of a hotel asset, the amount carries no real financial leverage: the administrative penalty exists, but it weighs little against the investment required. The real driver is therefore not the fine but the market (a discount on resale, refinancing terms, brand and investor requirements, the scheduled tightening of EU thresholds), all of which give an informed owner reasons to act before being legally forced to. The BACS decree, for its part, carries no direct fine: non-compliance surfaces during an audit or under the tertiary-sector decree, and then weighs on the building's valuation. The constraint thus works not through a penalty paid and forgotten, but through damage to reputation and, above all, to asset value.

This shift of the penalty, from the administrative fine to the asset itself, is decisive for what follows. It means non-compliance does not cost a one-off sum: it depreciates the property durably. A non-compliant asset becomes harder to sell, to finance and to hand over to a branded operator, and any informed buyer prices in its discount. Environmental regulation thus acts less as a tax than as an asset sorter.

For capital, this discount mechanism is not only a risk: it is an entry point. A non-compliant asset trades at an environmental discount, which a buyer able to fund the upgrade turns into value-add margin. Legal symmetry, however, has yet to be established, and the stakes are concrete for anyone holding leased hotel property. When a commercial lease is renewed, the rent is in principle capped at the change in an index. The rule gives way for single-purpose premises, which cannot be put to another use without major works or costly conversion: their rent is then set according to the practices observed in the sector (Commercial Code, Art. R. 145-10). A hotel is the classic case: its renewed rent generally escapes the cap. The open question lies elsewhere: can energy-performance works, whoever funds them, weigh in the assessment of single-purpose status? In a case concerning decontamination works at a service station, the Cour de cassation (France's highest civil court) held that single-purpose status "did not depend on how the costs were allocated between the parties"; one legal commentary considers extending this reasoning to energy works. No decision has settled the question to date, and this document takes no position.^¹⁹⁹ The uncertainty is itself a market fact: it lets energy risk be priced into the transaction rather than into the lease. The CBRE 2026 survey puts numbers on this mechanism. Asked about the size of the discount applied to assets with weak environmental credentials, respondents overwhelmingly placed it below 10%. The question offered no "no discount" option: it therefore measures the expected size of the discount, not how often a discount actually applies. Above all, the two most frequently cited behaviors are retrofitting existing buildings (36%) and acquiring specifically in order to improve credentials (30%). Outright exclusion remains marginal (7%).^²⁰⁰ In other words, for a notable share of the investors surveyed, energy-inefficient assets are less something to avoid than something to transform. When a discount applies, it is not a punishment: it is an entry price.

One clarification is needed, however, on the "reward" side of the mechanism: on the investor side, it remains poorly documented. The intentions CBRE measures concern retrofitting first: only 6% of investors surveyed say they are willing to pay a premium for strong environmental performance. In the Cushman & Wakefield survey, investors expect an average premium of 4.3% for assets with the most demanding environmental certifications. Both measures are self-reported: we have found no measure of this premium in completed transactions.^²⁰¹ On the operating side, research documents a green premium on the revenue side: a study conducted in Beijing finds, for comparable characteristics, a 6.5% higher room rate for certified hotels, with no decline in occupancy; more recent work in the Canary Islands finds a positive effect of eco-certification on revenue, but one that varies widely from one property to another.^²⁰² Conducted in Beijing and the Canary Islands, these studies do not transfer as such to France. Yet a hotel's value is built on its operating margin: an effect that flows through rate and avoided costs can end up in the price. The gap therefore has less to do with the nature of the mechanism than with when it becomes visible: measured in operations, it is quantified at acquisition only through stated intentions. Both lines of evidence nonetheless point to the same conclusion: the environmental constraint drives a two-sided transfer of value. It depreciates the asset in the hands of those who cannot renovate it, and rewards those who can. This is Section 4 translated into regulation.

7.3 — A stock that splits, and thresholds that create a false reprieve

The compliance status of the stock reveals not a uniform lag but a split between two parts of it, and the structure of the thresholds draws a second dividing line that is more telling still.

On energy performance, some of the declared buildings have already met the 2030 target, less often in tourism than elsewhere; on control equipment, the gap remains wide. It is this split, not a general lag, that makes the laggard asset identifiable, and therefore discountable.

The threshold structure, however, introduces a nuance the independent core must read clearly. The tertiary-sector decree applies only from 1,000 m^²; the BACS decree only above significant power thresholds. The average independent hotel (some twenty to thirty rooms) may fall below these thresholds; we did not find any public statistic that says in what proportion. Many properties in the independent core thus escape the direct obligation, for now.

This reprieve is misleading, for two reasons. First, the EU regulatory trajectory points to steadily lower thresholds: deferring the BACS threshold to 2030 does not remove the deadline, it postpones it, and the Energy Performance of Buildings Directive pushes toward a wider scope. Second, and more importantly, the market does not wait for the law. An energy-inefficient asset loses value even when it is not formally subject to the rules: its heavier energy and water costs reduce its operating profit, and therefore its value, and buyers, insurers and lenders may factor energy performance into their valuations. Being below the threshold protects against the filing obligation, not against the market discount. The independent core is not exempt from the problem; it is simply warned later.

7.4 — The cost of compliance: a shared obligation, unequal means to absorb it

That leaves the decisive question: who pays? This is where the environmental constraint meets the polarization mechanism that runs through this document.

Bringing a hotel up to energy standards requires heavy works: insulation, replacement of heating and cooling systems, automated controls, sometimes rework of the building envelope. For older buildings, common in the independent core and often located in city centers where the architecture constrains what can be done, the bill is high and the payback long; we did not find a public source that quantifies this cost per room (3.3.3). Yet it is precisely this operator (independent, with shrinking self-financing), or the owner of its property, who has the least means to undertake these works. The obligation is the same for everyone, but the tertiary-sector decree allows targets to be adjusted on the basis of a technical file (technical, architectural or heritage constraints, change of use, manifestly disproportionate cost), and the BACS decree exempts installations whose investment would not pay back within ten years. Those files still have to be put together: the stand-alone operator is the one with the least means to do so.

At the other end, value-add institutional capital reads the same constraint quite differently. For it, compliance is not a cost incurred but a line in the repositioning plan: it acquires a discounted energy-inefficient asset precisely because it knows how to finance the renovation, and then captures the revaluation, first through revenue, where studies outside France measure a premium on room rates, and therefore in principle through the margin, and through the removal of the discount that weighed on the asset; the premium at acquisition, for its part, is quantified only through stated intentions (4.3% in the Cushman & Wakefield survey), not through closed transactions. The same regulatory obligation is a heavy burden for the independent hotelier and a discounted acquisition opportunity for the well-equipped investor. Regulation does not merely sort assets: it accelerates their transfer into the hands of those able to upgrade them.

One existing mechanism does reduce the bill. A hotel qualifies for energy savings certificates (certificats d'économies d'énergie, CEE) as a commercial building. The scheme's sixth period runs from 2026 to 2030. Standardized operation sheets cover insulation, glazing, building management systems and heat pumps; the sheet for building management systems explicitly targets hotels and restaurants.^²⁰³ A case published by a scheme operator, a hotel renovation, reports certificates covering 27% of the project cost. It is one case, not an average.^²⁰⁴ This is not a subsidy. It is market-based funding, provided by energy suppliers, that the owner or operator can draw on without going through a public agency. It changes the math of an energy investment: the share covered reduces the debt requirement, and the balance pays back through the cost line the works reduce. For a property whose self-financing is shrinking, it is one of the few investments that partly fund themselves.

This is also where the France–Spain contrast noted earlier reappears, on environmental ground. In France, which layers obligations on top of scattered funding mechanisms (dedicated loans, regional grants, energy savings certificates), the modernization effort remains largely borne by the operator. The detail of available support is set out in 4.5; its comparison with the subsidy mechanisms deployed elsewhere in Europe is covered in 9.5.

7.5 — Beyond the energy balance: a broader field, and complexity that also sorts

The foregoing covers the most codified part of the environmental constraint: the building's energy balance. This is where the penalty on asset value is most legible, which is why this document focuses on it first. But reducing the environmental challenge for hotels to building energy consumption would be a simplification. The real field is broader, and it shifts part of the effort from capital to day-to-day operations.

Three dimensions extend beyond the energy balance. First, procurement and waste: short supply chains, organic offerings, food-waste reduction, sorting and reuse fall under a separate body of law (France's anti-waste and circular economy law, AGEC, of February 10, 2020, and the anti-food-waste framework), which weighs on hotel food and beverage and on purchasing. Second, water, whose scarcity, aggravated by droughts, is becoming an operating issue in its own right in tourist areas. Finally, the human and organizational effort: none of this can be put in place without staff training and reorganized procedures, a skills cost on top of the investment cost.

Two features of this broader field reinforce, rather than soften, this document's thesis. The first is complexity itself. Operators face a stack of standards from levels of government that do not coordinate (the municipality, the national government, the EU directive), each with its own thresholds, deadlines and filings. This complexity is not neutral: it costs time and expertise, and that cost weighs proportionally more on the small operator, which has no dedicated function, than on a group. Regulation, like credit or brand, sorts by the ability to comply. The second is the higher cost of "green" inputs: organic products, low-carbon renovation materials and energy-efficient equipment often cost more. The premium property, whose clientele values and absorbs this responsible upscaling, turns it into a selling point; the independent core, constrained on price, bears the extra cost without being able to pass it on, which is exactly the mechanism of Pressure 2. The ecological transition, taken in full, is therefore no exception: it too separates those who can monetize it from those who can only bear it.

This broader field would deserve full treatment of its own, which this document does not provide. We flag it here so as not to suggest that the environmental challenge comes down to building energy performance, and because it reinforces a conclusion already drawn: the constraint, whatever its form, falls hardest on the same player.

7.6 — What Section 7 establishes

For French hotels, the environmental constraint is not just one more compliance cost among others. It is an asset-sorting mechanism. On energy alone, the rules that apply to hotels (the tertiary-sector decree, the BACS decree, the mandatory energy audit) penalize less through fines than through the depreciation of non-compliant assets. They come on top of the obligations specific to establishments open to the public (fire safety, accessibility), which this document does not cover. The stock does not approach these deadlines as a single block: part of it has already met the 2030 target, less often in tourism than elsewhere, and the rest has not. It is this separation that gives the market something to sort on. The threshold structure offers the independent core a misleading reprieve, since the market depreciates energy-inefficient assets before the law even requires action. Above all, the cost of compliance hits hardest the independent operator least able to finance it, while value-add capital turns it into a lever for discounted acquisition and revaluation.

The environmental transition thus acts as an amplifier of the forces described in the previous sections. It does not create the polarization of the stock; it accelerates it, adding one more constraint to the existing pressures, and the bill once again falls on the independent core. The question is not whether the stock will be brought up to standard (the law will require it of the largest assets, and the market and the European trajectory of the least efficient ones) but who will own the assets once that is done.
