An O&M contract signed this year will still be running in 2030. That is the year the Décret tertiaire (France's tertiary decree on energy savings in commercial buildings) expects a -40% cut in consumption[1][1]RegulationsDecree No. 2019-771 of 23 July 2019, known as the Décret tertiaire (-40% target in 2030, reporting on OPERAT, buildings covered)See in sources ↓ and the year a BMS becomes mandatory from 70 kW[2][2]RegulationsDecree No. 2023-259 of 7 April 2023 (70 kW threshold, initial deadline 1 January 2027), then Decree No. 2025-1343 of 26 December 2025, postponing the BACS deadline for 70 to 290 kW buildings to 1 January 2030See in sources ↓. Who will prove the energy savings on your company's real estate portfolio then? Facility management has taken over from the general services department, which responded with call-outs. We cover its services, the FM's role, the chain of responsibility and then the clauses that make a guarantee hold.
Facility management: definition, services covered and the profession
Definition and origins of the discipline
Facility management (FM) organizes the services and resources that allow a company to keep its buildings running properly. Maintenance, upkeep, security, reception: the facility manager coordinates everything that lies outside the core business but shapes the working environment.
The ISO 41011 standard[3][3]RegulationsISO, “ISO 41011:2024, Facility management - Vocabulary” (second edition, February 2024, replacing the 2017 edition)See in sources ↓ defines it as an organizational function that integrates people, place and process to support the core business. In practice, it brings together facilities management and building management. Born in the United States, the discipline took shape in the United Kingdom and, in France, succeeded the general services department.
Did you know? The International Facility Management Association (IFMA) has existed since 1980[4][4]Studies and reportsIFMA, founding of the International Facility Management Association in 1980See in sources ↓. Yet it took until 2017 for an international standard, ISO 41011[3][3]RegulationsISO, “ISO 41011:2024, Facility management - Vocabulary” (second edition, February 2024, replacing the 2017 edition)See in sources ↓, to set the common vocabulary of the discipline.
Soft FM or multi-service: services to occupants
Soft FM (or multi-service) covers services to occupants, one of the three blocks (soft services, hard services, management) described by SYPEMI, the French facility management industry association[6][6]Studies and reportsSYPEMI (French facility management industry association), overview of facility management: soft services, hard services and managementSee in sources ↓:
• Cleaning of offices and restrooms • Front desk, switchboard and visitors • Security, guarding and access control • Mail and parcel handling • Staff catering and cafeteria • Space management and internal moves
A management layer coordinates these service packages, from workspace optimization to contract monitoring.
The day-to-day role: coordinating service providers, budgets and occupants
Day to day, facility managers arbitrate between service providers, budgets and occupants. Their role covers managing services, checking their quality and reporting. Every complaint ends up on their desk, hence trade-offs between comfort and consumption (one degree granted to a zone is often paid for across the whole loop). Ensuring a stable working environment takes organization, not firefighting reflexes.
Becoming a facility manager: training, skills and career prospects
To become a facility manager, training paths start after the French baccalauréat (high-school diploma), from a two-year technical diploma (BTS) to a specialized master's degree. Every job profile stresses a dual skill set: technical when dealing with maintenance contractors, managerial when dealing with budgets. Job offers come mainly from real estate, where FM jobs are paid according to the size of the portfolio.
Who decides, who executes, who holds the data: the building's chain of responsibility?
Owner, property manager, FM, maintenance contractor and integrator: who does what
On a single real estate portfolio, five players share building management without anyone seeing the whole chain. The diagram below lines them up link by link: what each one decides, what it executes and the data it holds. The filters isolate one row at a time.
Follow the data from one link to the next and the problem jumps out. The BMS trend logs sit with the integrator, the CMMS (computerized maintenance management system) tickets with the O&M contractor and the invoices with the property manager. Yet the owner of the heating or air-conditioning systems bears the obligation under the BACS decree (French decree 2020-887 on building automation and control systems)[7][7]RegulationsDecree No. 2020-887 of 20 July 2020, known as the BACS decree (buildings above 290 kW by 1 January 2025, obligation borne by the owner)See in sources ↓ and, together with the tenant, the obligation under the Décret tertiaire[1][1]RegulationsDecree No. 2019-771 of 23 July 2019, known as the Décret tertiaire (-40% target in 2030, reporting on OPERAT, buildings covered)See in sources ↓. The chain of responsibility breaks precisely where the data changes hands. The FM under a multi-technical contract manages maintenance and technical management. It rarely gets access to the sources that would prove its result. Who, in your organization, is responsible for pulling this data together?
Holding a performance guarantee: drift, measuring results and the clauses to lock down
What a performance commitment changes for the O&M contractor
Under a performance commitment, the job changes units. The contract no longer counts completed maintenance routines: it counts kWh. The O&M contractor moves from a best-efforts obligation to an obligation to achieve a result, with penalties if the target is missed and a bonus if it is exceeded. Complying with maintenance levels[5][5]RegulationsAFNOR, “NF X 60-000, Industrial maintenance - Maintenance function” (April 2016, replacing the 2002 FD X 60-000 guidance document), five maintenance levelsSee in sources ↓ is no longer enough. The performance guarantee turns facility management into a service judged against a quantified target, which the company can challenge.
Drift in year 2: VIP complaints, degraded mode and lost settings
In the second year, energy drift comes in through three doors. The VIP complaint (the director on the top floor who demands 24-25 °C all year round, seen many times) is settled by a setpoint raised by hand and never lowered again. Degraded mode follows: a sensor fails, the equipment runs in backup mode and nobody goes back to it. Then settings get lost for lack of traceability. Each patch makes one workstation comfortable and makes the whole building pay, during full occupancy as well as at weekends. To detect drift before the annual review, the energy signature remains the simplest tool: a straight line linking consumption to heating degree days (HDD).
Silent meters and gappy trend logs: when data undermines the guarantee
Open the trend logs of a portfolio under contract. You often find the same thing: a meter disconnected for weeks, data gaps, duplicates, spikes nobody can explain. Yet the monitoring system displays a clean curve. Data quality, for its part, was never checked when the installation was commissioned.
A guarantee you cannot measure is a guarantee you cannot hold.
Activity indicators and result indicators: what proves performance
Most O&M reports pile up activity indicators. They show that the work is done, without saying whether it has any effect. The table below separates them from result indicators and shows who produces each one.
| Indicator | Type | Who produces it | Verifiable by a third party? |
|---|---|---|---|
| Completion rate of preventive maintenance routines | Activity | O&M contractor, via the CMMS software | No, self-reported |
| Response times | Activity | O&M contractor, CMMS tickets | Partially, timestamps entered by the O&M contractor |
| Closed CMMS tickets | Activity | O&M contractor | No, closing a ticket is not resolving it |
| HDD-corrected HVAC consumption against the baseline | Result | Meters and BMS trend logs | Yes, according to the IPMVP protocol |
| Setpoint stability | Result | BMS trend logs | Yes, if trend logging is complete |
| Active overrides (manual overrides) | Result | Supervision system | Yes, through a dated survey |
| Meter data completeness rate | Result | Metering trend logs | Yes, calculable from the exports |
Result indicators do not replace maintenance levels. They tell you whether the maintenance was worth it. At Valeo, measurement carried out according to the IPMVP protocol established -28.6% on heating and electricity[8][8]Field resultsFoobot/Valeo case study, -28.6% on heating and electricity measured according to the IPMVP protocolSee in sources ↓. The figure holds because a third party can recalculate it.
Baseline, HDD correction and the IPMVP protocol: verifying savings
A self-reported saving compares one invoice with another. A measured saving starts from a baseline: the reference consumption, corrected for heating degree days (HDD, called DJU in France) to neutralize a mild winter.
The International Performance Measurement and Verification Protocol, the IPMVP protocol, sets the method, the adjustments and the acceptable uncertainty. A third party can redo the calculation. Only a cost reduction established this way stands up in front of an owner. It also serves as the basis for the carbon footprint assessment.
CMMS, BMS and hypervision: what each tool really records
The CMMS records call-outs, not kWh. The CMMS software knows that a filter was changed. It does not know whether the AHU has consumed more since. The building BMS, on the other hand, records setpoints, states and meter readings. Hypervision, that multi-site supervision layer, aggregates this data across the real estate portfolio. Artificial intelligence only has a place where there is real complexity: for lighting, a presence detector is enough.
From annual checks to continuous control: what changes for the guarantee
An annual check can uncover drift up to twelve months after it starts. Continuous control spots it within a few days, because setpoints adjust as the weather and occupancy change. For a multi-technical service provider, this pace makes it possible to optimize operations before the annual review and improve the result, with or without artificial intelligence.
Data, access and the actual condition of the installations: what to establish before signing
Before signing, ask the questions nobody asks. Do you own the BMS trend logs? In what format do they come out? Who actually provides access to the supervision system? How many overrides (manual overrides) are active today? Do the functional analyses still describe the equipment in place? Without an assessment of the actual condition of the installations, implementing the guarantee rests on a snapshot nobody took. Data rights are negotiated before signing.
Savings calculation, OPERAT reporting and reversibility: what the contract must put in writing
The assessment tells you where the building stands. The contract, for its part, says who will answer for what throughout its term. Three subjects deserve an explicit clause: the savings calculation method, who files on OPERAT (the French government platform for reporting energy consumption under the Décret tertiaire) and the exit from the contract. Here are the questions to settle between building owner and O&M contractor before the commitment. Tick those that already have a written answer.
An empty box does not block signature: it points to the clause to write first. The reversibility clause deserves special attention. It ensures that at the end of the contract, the trend logs, access rights and documentation return to the company in a usable format. Without it, the site's technical management remains tied to the outgoing service provider. You still need a BMS reliable enough for these clauses to have a purpose.
Make reliable, then control: Foobot services for the O&M contractor under a guarantee
BMS advisory: getting the BMS back in shape before committing
Before signing a guarantee, the BMS must be able to hold a setpoint. BMS advisory starts there: removing overrides (manual overrides), bringing sequences back into line, cutting alarms down to the ones that matter. Meter reliability work then deals with disconnections, data gaps and duplicates. This work has value in itself. It is not an entry ticket to AI: a site made reliable can perfectly well stop there.
AI Control: holding the guarantee between two reviews
A performance guarantee is rarely lost on a breakdown. It is lost on a setpoint raised for a complaint, an optimal start brought forward “to be safe”, a heating curve never touched since handover. None of these drifts triggers an alarm. All of them are paid for at the annual review.
When the BMS holds its setpoints and the site retains real complexity (hot water and chilled water loops, AHUs, optimal start times), Foobot's AI Control takes over the control. It learns in a digital twin of the building, calibrated on its actual consumption, then adjusts HVAC setpoints every 15 minutes through the existing BMS, without major works. Maintenance remains the O&M contractor's job. What changes is that control no longer waits for the annual review to be corrected.
The result is measured like the guarantee itself, according to the IPMVP protocol and against the reference year: −18% in HVAC electricity consumption at the Hachette Livre headquarters in Vanves, −28.6% at Valeo. For the O&M contractor under a guarantee, the gap is corrected within the week instead of being argued over at the annual review.
What makes a performance guarantee hold over time
A performance guarantee is not won in the control loop. It is won beforehand, on three unspectacular things: data that belongs to you, a baseline signed by both parties and clauses that say who clears what. The company that outsources its technical management keeps this foundation in hand. The O&M contractor committing to a result has every interest in demanding it just as much.
What remains is the part the contract does not write: the pace. Drift spotted at the annual review gets negotiated. Spotted within the week, it gets corrected. If your guarantee still depends on an annual reading, measure what continuous control would change on your actual trend logs.

FAQ - facility management
What is the role of the Facility Manager?
They coordinate service providers, arbitrate budgets and respond to occupants. Under a performance commitment, the role expands. Facility managers no longer just report on the work carried out: they are accountable for a result measured on the building's consumption.
Why is facility management essential to the proper operation of sites or buildings open to the public?
A site open to the public combines safety obligations, service continuity and occupancy peaks. FM is essential there: it organizes maintenance, inspections and services to keep the site running properly. A failed alarm immediately becomes a safety issue.
What is facility management?
It is the organization of the services and facilities management that allow a company to operate its buildings. Formalized in the United States and then in the United Kingdom, the discipline extends the general services function by adding a technical scope: maintenance, HVAC and BMS.
How do you become a facility manager?
To become a facility manager, you follow a training program open after the French baccalauréat (high-school diploma), in property management, HVAC engineering or services management. The job profile combines technical skills and contract management. Job offers mainly target commercial real estate, where a facility manager position often requires operations experience.
What are the challenges of facility management?
Energy drift first: setpoints raised after a complaint, degraded modes never cleared. Next comes incomplete data, which makes it impossible to prove an obligation to achieve a result. The third challenge is contractual: who holds the access rights and the trend logs?
What services does facility management include?
Facility management services cover two blocks. Hard FM groups multi-technical maintenance, HVAC and building fabric upkeep. Soft FM covers services to occupants: cleaning, reception, security, mail, catering and space management.
What tools are used for facility management?
CMMS software schedules and records call-outs. The BMS controls and logs setpoints, states and meter readings. Hypervision aggregates several sites in a single view. None of these tools proves a saving on its own: you need a baseline and a measurement method.
How can facility management be optimized?
Make things reliable before optimizing: clear manual overrides, repair meters, update sequences. Only then come space optimization and fine-tuned control. Every claimed saving is verified according to the IPMVP protocol, with HDD weather correction.
