Since 1 January 2025, a French decree has required a compliant BMS in every commercial building above 290 kW[1][1]RegulationLégifrance, “Decree No. 2020-887 of 20 July 2020 on building automation and control systems in non-residential buildings” (BACS decree)See in sources ↓. The obligation goes into the asset's business plan. The technical data needed to meet it goes in far less often. Real estate asset management makes decisions on a real estate portfolio for its financial performance. Here we set out its definition, its missions and the real estate strategy behind it. Then we show where, in a real estate portfolio, data gets lost between the decision and the equipment.
Real estate asset management: the discipline and the asset manager's job
Definition: managing a building as a financial asset
Real estate asset management means managing real estate assets on behalf of an owner or investors. It consists of buying, adding value to a portfolio, making trade-offs, then selling, according to set investment strategies. In real estate, the function carries the value of the asset, not its day-to-day operation.
On its own account, a property company keeps the function in-house. On behalf of third parties, an asset management company acts for an investment fund. The legal framework then depends on the vehicle: the Hoguet Act (French law on real estate transactions)[2][2]RegulationLégifrance, “Law No. 70-9 of 2 January 1970” (Hoguet Act)See in sources ↓ or the AIFM directive[3][3]RegulationEUR-Lex, “Directive 2011/61/EU on Alternative Investment Fund Managers” (AIFM)See in sources ↓. The real estate asset manager is also accountable to investors for a sustainable real estate pathway.
Asset manager, property manager, facility manager: who decides what?
Property management and the technical manager carry out what the AM decides. The property manager handles leasing management: leases, rent collection and compliance. The facility manager provides services to occupants. The AM, accountable to the owner, makes the decisions, then delegates the technical side.
Two similar job titles are easily confused. The real estate fund manager runs an entire fund. The portfolio manager balances several portfolios. The asset manager role, for its part, is exercised building by building.
Missions, from acquisition to sale
The asset manager's job turns a strategy into dated decisions. Asset manager missions follow the holding cycle:
- acquisition and due diligence of the asset
- multi-year business plan for the building
- lease negotiation with tenants
- valuation, sale and investment optimization
- reporting to investors and committees
The real estate asset manager in charge of the business plan keeps the decision. They delegate the technical side to the players described above.
Skills: finance, real estate law and technical literacy
The asset manager position is built on finance and real estate law. It requires the ability to analyze a yield or a legal risk on a lease. Asset management training covers financial performance well. Reading a BMS, almost never. The result: the technical opinion behind a capex often comes from whoever will sell the works.
Asset management fundamentals: business plan, capex and the asset's obligations
The asset business plan, foundation of the investment strategy
At the heart of asset management fundamentals, the asset business plan is a multi-year plan. It sets assumptions for rents, service charges, works and exit value in its market. It turns investment strategies into decisions: hold, renovate, reposition or sell. Every real estate investment decision ties back to it.
How does an asset manager decide on an energy capex?
Three points come before any energy capex project. The first sets capex against opex: the real estate capex vs opex trade-off compares a replacement with better-run operation, or even an energy performance contract. The second comes down to one question: is the obsolescence real or simply declared? The third is the IRR, which can lengthen significantly on small commercial sites.
Our position: a capex signed on the opinion of whoever will sell the works is premature. Real estate obsolescence is verified by tests before any implementation. If a replacement quote is already on the table, now is the time to ask for a second opinion.
An obsolescence audit does not decide for you. It puts the technical opinion back on the side of someone who does not sell the works. The exit value written into the plan is protected as a result.
BACS decree and Décret tertiaire: what the asset must comply with
Two decrees impose obligations on commercial assets. A financial incentive comes on top. Each of these texts becomes a line in the business plan, with an identified data producer.
| Text | Type | Threshold | Deadline | What the AM checks | Who produces the data |
|---|---|---|---|---|---|
| BACS decree No. 2020-887[1][1]RegulationLégifrance, “Decree No. 2020-887 of 20 July 2020 on building automation and control systems in non-residential buildings” (BACS decree)See in sources ↓ | Regulatory obligation | HVAC > 290 kW | Compliance since 1 January 2025 | BMS in place, required functions delivered | BMS integrator, operator |
| BACS decree, intermediate band[4][4]RegulationLégifrance, “Decree No. 2025-1343 of 26 December 2025”See in sources ↓ | Regulatory obligation | HVAC from 70 to 290 kW | 1 January 2030 (decree No. 2025-1343); new buildings not covered by the postponement | Works budgeted in the business plan | BMS integrator |
| Décret tertiaire No. 2019-771[5][5]RegulationLégifrance, “Decree No. 2019-771 of 23 July 2019” (Décret tertiaire)See in sources ↓ | Regulatory obligation | ≥ 1,000 m² of commercial floor area | -40% by 2030, -50% by 2040, -60% by 2050 | Reference consumption and trajectory | Operator, property manager |
| CEE BAT-TH-116[6][6]RegulationFrench Ministry for Energy, “CEE sheet BAT-TH-116”See in sources ↓ | Financial incentive (CEE energy-savings certificates) | Class A or B | None | Eligibility, distinct from compliance | BMS integrator |
The Décret tertiaire (France's tertiary decree on energy savings in commercial buildings) and the BACS decree (French decree 2020-887 on building automation and control systems) consume the same data. To meet them across a real estate portfolio, you need reliable meters maintained by an identified technical manager.
Did you know? The BACS decree does not impose any class of NF EN ISO 52120-1[1][1]RegulationLégifrance, “Decree No. 2020-887 of 20 July 2020 on building automation and control systems in non-residential buildings” (BACS decree)See in sources ↓. It sets its own functional requirements. And a building's class remains that of its weakest function.
CRREM, GRESB and DPE: how the frameworks change the decision
Three market frameworks also weigh on value, with no regulatory deadline. The pairing of CRREM and stranding date measures the risk of an asset leaving its carbon pathway. GRESB rates real estate investment funds. The DPE, the French Energy Performance Certificate (EPC), feeds the price gaps described by green value and brown discount. What they have in common: each one consumes operating data.
How to optimize a real estate portfolio from operations?
Energy drift, a loss of value missing from the business plan
Energy drift of an office building since handover
HDD-corrected consumption HandoverEnd of warranty yearFollowing years Years since handover HDD-corrected consumption Level at handover Overconsumption outside the business plan- 1VIP complaintA setpoint raised for a demanding occupant, never brought back down.
- 2Degraded modeA faulty sensor or controller: the installation runs in fallback mode, without fine control.
- 3Untracked manual overrideA manual override set as a quick fix, left active for lack of traceability.
A new or renovated building often sees its consumption creep up year after year. Energy drift sets in little by little: a VIP complaint, degraded mode, manual overrides never removed. The purely illustrative curve below follows this mechanism from handover (corrected for heating degree days, HDD, called DJU in France): each step is a temporary setting that became permanent.
Each step inflates a building's operating cost without ever appearing in the business plan. A BMS class is not performance. Preventive maintenance changes the filters. It does not catch up with drift.
What Foobot brings the real estate asset manager on the technical side
BMS advisory: a technical opinion that does not come from whoever sells the works
BMS advisory addresses the loop flagged in the decision chain. Before a capex, the “Obsolete” BMS audit gives a second opinion on real obsolescence, backed by replacement tests. At handover and then during the warranty year (defects liability period), we test the sequences in operation. During operation, we remove manual overrides and make the meters reliable. This data-reliability work stands on its own: no AI phase is required after it.
Before the next asset decision, qualify the data it rests on
Asset management decides on figures produced far from the decision, in a boiler room or a supervision system the AM never opens. A capex, an ESG report or a sale strategy should not be signed on unqualified data. You cannot steer an asset on data you have never checked. The order holds for any real estate portfolio: make the data reliable first, optimize second. Once the meters are reliable, control turns that data into lower service charges and measurable value.

Nine links between the decision and the equipment
Each link decides, produces a document and passes on to the next a slightly more summarized piece of technical information.- 1Owner or fund Decides: the holding strategy and the expected return. Produces: the management mandate and the exit targets. Information gets diluted: it only reads indicators consolidated at portfolio level.
- 2Asset manager Decides: hold, renovate, reposition or sell. Produces: the asset business plan and the capex budget. Information gets diluted: decides on summaries, never on BMS trend logs. Signs off the capex
- 3Property manager Decides: leasing management and the recharging of service charges. Produces: the service charge budget and the leasing report. Information gets diluted: consumption becomes amounts to recharge.
- 4Facility manager Decides: the level of service provided to occupants. Produces: the operation contract and its service indicators. Information gets diluted: an occupant complaint weighs more than a consumption drift.
- 5Operator or maintenance contractor Decides: settings, exceptions and interventions. Produces: intervention reports and the opinion on equipment condition. Information gets diluted: a manual override set after a complaint is not always tracked. Issues the technical opinion
- 6BMS integrator Decides: the points reported and the sequences programmed. Produces: the functional analysis, the BMS points and the quotes for works. Information gets diluted: the documentation describes what was planned, not always what is running. Prices the works
- 7Supervision Decides: nothing; it displays and logs trends. Produces: BMS trend logs, alarms and curves. Information gets diluted: gaps in trend logs, duplicates and disconnected points go unnoticed.
- 8Controllers Decides: real-time control, according to the setpoints received. Produces: measurements and equipment states. Information gets diluted: a setpoint overridden locally does not always reach the supervision system.
- 9HVAC equipment Decides: nothing; they execute. Produces: actual consumption, the one that gets billed. Information gets diluted: the only raw data in the chain, it is also the furthest from the decision.
Can your operating data support an asset decision?
Answer for the asset whose next capex is closest. The result is indicative only.- Have your meters been checked since handover?
- Are your BMS trend logs free of gaps?
- Are manual overrides tracked?
- Is your baseline corrected for degree days (HDD, DJU in France)?
- Does the owner hold the access credentials to the supervision system?
- Do the bills match the sub-metering?
- Do you know where the figures in your latest report come from?
FAQ - real estate asset management
What is real estate asset management?
This discipline consists of adding value to a portfolio by managing real estate assets: acquisition, works, leasing and sale. The asset manager makes decisions on its own account or on behalf of third parties. Its raw material is still figures produced by other players.
What are an asset manager's missions?
In real estate, the asset manager handles acquisition, the business plan, lease negotiation, valuation and then sale. Their role as asset manager includes valuing a commercial asset and reporting to investors. The technical side is delegated.
What are the fundamentals of asset management?
The fundamentals of asset management come down to three blocks: an asset business plan, consistent investment strategies and portfolio management that decides whether to hold, renovate or sell. On top of these come the regulatory obligations that constrain every real estate investment.
How do you optimize a real estate portfolio?
Act on three levers: office vacancy, service charges and appraised value. On the operations side, make the meters reliable first, then track down energy drift. 👉 Optimizing the value of a real estate asset portfolio starts with verified data.
How do you become a real estate asset manager?
The classic route is a master's-level degree (bac + 5 in France) in finance or real estate, at a university or a business or engineering school, with real estate law. Career changers often move into asset management from wealth management, audit or a consulting firm.
What does an asset manager earn?
There is no common pay scale: gross annual salary depends on the type of employer, assets under management, seniority and location, Paris or the regions. To benchmark an asset manager position, the salary benchmarks published by Apec (France's executive employment association)[7][7]Studies and reportsApec, executive salary benchmarksSee in sources ↓ remain the most stable reference.
What jobs are there in real estate asset management?
Positions are concentrated in Paris and France's major cities: asset manager, portfolio manager, real estate fund manager, property manager and property administrator. Job offers come from asset management companies, property companies and real estate financing banks.
