Hiring an energy manager is becoming a question of timing: Directive (EU) 2023/1791 requires an energy management system above 85 TJ per year from 11 October 2027[1][1]RegulationEuropean Union, “Directive (EU) 2023/1791 on energy efficiency”, thresholds of 85 TJ (energy management system) and 10 TJ (energy audit)See in sources ↓. Job offers are following, driven by the energy transition. Missions, tools, training, salary: this job depends above all on your meters. Plugged into unreliable data, the person in the role steers a dashboard, not a portfolio.

Energy manager: definition, job titles and what is at stake in energy management

Definition: what an energy manager actually controls in a commercial portfolio

An energy manager is responsible for the energy performance of a site or a portfolio of commercial buildings. They measure consumption, detect drift and build the action plan to optimize how equipment is used. They also support the operator in choosing each technical solution. The role the energy manager plays in the company's energy strategy comes down to one requirement: proving every gain in energy efficiency.

Energy management is an approach, the EnMS (energy management system, SMÉ in French), equipped with an EMS. Practiced without reliable meters, energy management is like grading an exam paper without reading it.

Energy officer, économe de flux, energy champion: the same job?

The économe de flux (a French local-authority energy controller) is found mostly in local authorities, which manage schools and swimming pools. GTE (gestion technique énergétique, technical energy management) refers to the same energy management, equipped with a supervision system.

The energy champion (référent énergie) often holds a part-time role, entrusted to a project manager. The energy engineer, on the other hand, designs installations in industry: a different job description, which we distinguish in the FAQ.

Décret tertiaire and BACS decree: two obligations, two timelines

Both texts impose obligations. They do not impose the same thing. The Décret tertiaire (France's tertiary decree on energy savings in commercial buildings) sets a result: reduce the final energy consumption of commercial buildings of 1,000 m² and more by 40% in 2030, 50% in 2040 and 60% in 2050[2][2]RegulationLégifrance, “Decree No. 2019-771 of 23 July 2019” (Décret tertiaire), targets of -40%, -50% and -60% and reporting on OPERATSee in sources ↓.

The BACS decree (French decree 2020-887 on building automation and control systems), for its part, sets a piece of equipment: a building automation and control system, required above 290 kW since 1 January 2025[3][3]RegulationLégifrance, “Decree No. 2020-887 of 20 July 2020”, building automation and control systems in non-residential buildings (BACS decree)See in sources ↓. For a company, what is at stake in energy management for a real-estate portfolio lies in implementing both together: one sets the target, the other the tool.

Did you know? The deadline for existing buildings of 70 to 290 kW, initially set at 1 January 2027, was postponed to 1 January 2030 by Decree No. 2025-1343 of 26 December 2025[4][4]RegulationLégifrance, “Decree No. 2025-1343 of 26 December 2025” (art. 1, amending article R. 175-2 of the French Construction and Housing Code), postponement of the deadline for existing buildings of 70 to 290 kW to 1 January 2030See in sources ↓.

Directive (EU) 2023/1791: an EnMS required above 85 TJ in October 2027

The European directive sets the deadline at 11 October 2027[1][1]RegulationEuropean Union, “Directive (EU) 2023/1791 on energy efficiency”, thresholds of 85 TJ (energy management system) and 10 TJ (energy audit)See in sources ↓. After that date, any company whose average consumption over three years exceeds 85 TJ per year will need a certified EnMS. Above 10 TJ, the same text requires companies without an EnMS to carry out an energy audit every four years, the first one being due on 11 October 2026[1][1]RegulationEuropean Union, “Directive (EU) 2023/1791 on energy efficiency”, thresholds of 85 TJ (energy management system) and 10 TJ (energy audit)See in sources ↓. The ISO 50001 standard serves as the reference: energy policy, energy review, baseline, action plan. We detail how to implement it in our page on the energy management system.

Costs, carbon footprint, asset value: what energy management must prove

Bills, carbon footprint, asset value: what is at stake in energy management comes down to proof. The sector has long promised double-digit savings through better control. The promise only holds on reliable systems, which property companies' energy transition plans rarely check.

The return on investment also needs qualifying: it gets considerably longer on small commercial sites. As for environmental impact, the tonnes of greenhouse gas avoided only feed credible sustainability reporting if the result is measured.

An energy manager's missions: from the meter to the action plan

Setting a baseline corrected for heating degree days

An energy manager's missions start with the energy review: significant energy uses, then the baseline. This baseline is normalized using heating degree days (HDD, DJU in French), otherwise a mild winter passes for a saving. The first trap on a commercial site: energy drift, consumption that creeps up every year without anyone noticing. No study holds without this corrected data.

What tools does an energy manager use day to day?

Day to day, the role relies on five tools:

• the BMS, which acts on the HVAC equipment; • the supervision system or hypervisor, which aggregates several sites; • the EMS, which collects, normalizes and alerts; • the spreadsheet, still there for trade-offs; • the OPERAT platform (the French government platform for Décret tertiaire reporting), for the regulatory declaration.

The EMS detects the drift, the BMS corrects it: an EMS that does not write to the BMS remains a dashboard. Before you choose energy management software, check whether the solution has technical write access to the system.

From the BMS point to the action plan: where the data breaks

Every mission described above depends on an upstream chain that nobody looks at. A piece of data passes through six links before landing in an action plan. The diagram below gives, for each one, the typical failure and the question to ask your operator. Click on a link to see what it contaminates downstream.

From the BMS point to the action plan

Energy manager missions: where the data breaks

Six links, from the sensor to the action plan. Scroll along the track, then click on a link to simulate a failure.
Click on a link: the diagram shows what it contaminates downstream.

A single broken link is enough. An offset sensor skews the control, a data gap empties the baseline, a manual override never released keeps an AHU running at night. The energy management tool then shows a clean but false curve. Technical implementation therefore starts with an audit of this chain, starting from the sensor.

Building the action plan: make data reliable before optimizing energy consumption

Make it reliable before optimizing: that is the order we stick to on every project. First we release the overrides, then we put the sequences back in order to cut unnecessary running hours.

AI only comes in afterwards, if the need justifies it. For lighting, a simple occupancy sensor is often enough, with no predictive algorithm. A project manager who wants to optimize energy consumption without this step weakens their return on investment. They are optimizing an equipment usage they cannot see.

Hire, outsource or make the data reliable first?

Do you need an energy manager for a portfolio of 10 sites?

No threshold decides for you. The need depends on the state of the BMSs and the quality of the trend logs, site by site. Before any hiring, look at what your meters can say about your commercial real-estate portfolio. Energy manager job offers are written after this assessment. Your company can then ask the real question: a full-time role dedicated to energy, or a shared function?

Does an external energy manager exist?

Yes, in three forms: a person employed by the operator, an energy service company under contract, or an external energy management consultant who supports your team. Expertise matters. The decisive criterion remains independence from whoever sells the works. A company that reads your data and then prices the replacements is both judge and party.

Four organizations compared, criterion by criterion

The table below compares four organizations on six criteria. Read it while asking yourself who, in your organization, holds the trend logs today.

Manual overrides Spotted, rarely released Released if the contract provides for it Reported Released: removal of manual overrides in operations-phase BMS advisory
A comparison of organizations, not of providers: each situation depends on the contract and the rights granted on the BMS.

The table says the essential: none of these organizations fixes a duplicate meter just by existing. They all inherit the data they are given. Before any hiring or any contract signature, the meter question is therefore settled upstream.

Six questions to test an energy manager, candidate or provider

Here are six questions a recruiter or a buyer can ask in an interview. They cover the BACS decree, the ISO standard on classes and the CEE sheet (CEE energy-savings certificates), where the market most often gets confused. Click on each one: the expected answer appears with the signal that should make you doubt.

These questions test a simple skill: reading the texts rather than the press releases. A provider who confuses compliance and CEE may sell you a class that the decree does not require.

Becoming an energy manager: training, salary, positions

What training do you need to become an energy manager?

To become an energy manager, the classic route is a five-year master's-level degree (bac+5 in France): engineering school, business school or a master's in energy and environment. Studies often end with a work-study placement. Bridges exist from HVAC operations or IT, provided the profile is completed with ISO 50001 training. No degree replaces years spent reading meter curves.

The skills that count: knowing how to doubt BMS data

The rare skill lies less in the spreadsheet than in a reflex: knowing how to doubt BMS data before using it (the meter stuck at zero for a whole month that nobody reported). Without this technical expertise, no energy strategy holds up.

Energy manager salary: what makes pay vary

An energy manager's salary depends on five factors: experience, sector, type of employer, managerial (cadre) status and location. A junior manager at a service provider does not negotiate the same pay conditions as a senior at a building owner. Paris and the large regional cities do not have the same pay scales. Company size also plays a part.

Job types: junior, senior, energy & commissioning manager

Energy manager positions follow a clear progression. The junior manager starts on a few sites. The senior takes over an entire portfolio or a multi-site industrial business. The energy commissioning manager, attached to handover, checks that the equipment holds its setpoints. Then come project manager profiles, or energy officer roles in local authorities.

Energy manager job offers: who is really hiring?

In November 2026, LinkedIn shows more than 4,000 offers in France on a broadened scope[7][7]Press and job listingsLinkedIn, “Energy Manager jobs in France”, more than 4,000 results on a broadened scopeSee in sources ↓. Apec (the French executive employment agency)[5][5]Press and job listingsApec, “Energy Manager job offers” (Offres d'emploi Energy Manager), keyword searchSee in sources ↓ and Indeed[6][6]Press and job listingsIndeed, “Energy Manager jobs”, list of job offersSee in sources ↓ also publish ads under this job title. Behind these energy manager job offers, the recruiter is often a service provider, from industry to services.

This active recruitment concerns you directly: your portfolio's data is often read by an employee of the company that sells the works.

What Foobot brings to an energy manager, in-house or external

Making meters reliable before the first dashboard

Our BMS advisory starts with metering. We track down disconnections, data gaps, duplicates and invisible drift, site by site, across the whole real-estate portfolio. This first management work supports in-house energy management without replacing it. A building whose meters tell the truth can be controlled over the long term, whether the energy function is in-house or not. This reliability work stands on its own, with no AI phase behind it.

Before hiring an energy manager, check what they will have to read

An energy manager, in-house or external, is only worth as much as the data they read. Hiring before making the data reliable means paying a salary to comment on gaps in the history. The order matters: meters checked, overrides released, baseline corrected for HDD, then the role, then possibly AI. This sequence protects your energy spending as much as your OPERAT declarations. To find out what your meters really say, ask for a quote for an audit of your metering.

Let's talk

FAQ: the energy manager job in questions

What is an Energy Manager?

It is the professional who organizes energy management for a company or a portfolio. They measure, prioritize actions and report. Their contribution to energy efficiency depends directly on the reliability of the meters they use.

What is the difference between an Energy Manager and an energy engineer?

The energy engineer designs or sizes installations: generation, networks, equipment. The energy manager role steers operations and performance over time. Both require a technical foundation. Energy management is more about organization and measurement.

What concrete benefits does an Energy Manager bring to a company?

The role the energy manager plays is to turn consumption that is endured into decisions. The expected result: measured savings, drift spotted early and compliance maintained. Without reliable metering, these benefits remain estimates.

What digital tools does an Energy Manager use to manage performance?

A BMS to act, an EMS to measure and alert, a hypervisor to aggregate several sites, a spreadsheet and OPERAT. The decisive criterion remains read or write access to the BMS, detailed above with each tool.

Should the Energy Manager function be kept in-house or outsourced?

Both work if the data is reliable and if whoever reads it has no works to sell. An in-house role keeps the portfolio's memory. An external consultant brings perspective gained across several portfolios.

How does the Energy Manager help comply with the Décret tertiaire?

They build the baseline, corrected for heating degree days, then track consumption building by building. They prepare the annual declaration on OPERAT and prioritize actions to reduce consumption towards the 2030, 2040 and 2050 milestones[2][2]RegulationLégifrance, “Decree No. 2019-771 of 23 July 2019” (Décret tertiaire), targets of -40%, -50% and -60% and reporting on OPERATSee in sources ↓.

Can you become an Energy Manager with an IT background?

Yes. The profile is even gaining ground. IT training brings a valuable skill: processing, cross-checking and qualifying data. It will need to be completed with thermal engineering, HVAC and the regulatory texts, often through a specialized master's degree.

What career opportunities are there after Energy Manager training?

Opportunities cover industry, property companies, local authorities, operators and service companies. A master's in energy and environment also opens the way to consulting or to the handover of new buildings. Job titles vary a great deal from one employer to another.

Is work-study possible to become an Energy Manager?

Yes. Many master's programs and five-year degrees can be followed on a work-study basis. It is often the most direct route to becoming an energy manager: the field quickly teaches you to read a real BMS, with its flaws.

Are there certifications dedicated to the Energy Manager?

No certification is mandatory to practice. Some training courses prepare you to run an EnMS according to ISO 50001. Other certifications attest to mastery of IPMVP. They validate a method, not the ability to make a meter reliable.

What is an energy manager's salary?

An energy manager's salary varies with experience, sector, type of employer and region. The role generally comes with managerial (cadre) status. In the Paris region, Michael Page's 2027 salary survey puts the fixed gross annual salary between €40,000 and €80,000, with an average of €56,000[8][8]Press and job listingsMichael Page, “Energy manager (energy efficiency) salary 2027”, salary survey, fixed gross annual salary in the Paris region excluding variable pay: €40,000 (low), €56,000 (average), €80,000 (high)See in sources ↓.
