A regulatory, financial and environmental opportunity for wealth managers
Faced with the new requirements of the European directive on energy efficiency (directive 2023/1791 transposed by the DDADUE law), the implementation of an ISO 50001-certified Energy Management System (EMS) is becoming a strategic lever for companies and public players in the tertiary sector. This system not only makes it possible to avoid recurring regulatory audits, but also offers an effective structure for managing and improving the energy performance of any building stock.
Why implement an ISO 50001 certified EMS?
From October 1, 2025, any company whose annual energy consumption exceeds 2.75 GWh (10 TJ) must:
• Either carry out an energy audit (standard NF EN 16247) no later than October 11, 2026 and then every 4 years,
• Either implement an ISO 50001 certified EMS, in which case the periodic audit is no longer required.
Any company whose annual energy consumption exceeds 23.6 GWh (100 TJ) must:
• Either implement an ISO 50001 certified EMS by October 11, 2027 at the latest
• Either implement an Energy Performance Contract (EPC) covering 80% of the company's final energy consumption
Thus, ISO 50001 certification constitutes a sustainable and recognized path to regulatory compliance.
What are the benefits of an ISO 50001 EMS for commercial buildings?
A direct impact on your operating costs
According to an AFNOR study from April 2024, the observed benefits are:
• -10 to -25% energy consumption on targeted uses,
• Better reliability of investments (thanks to monitoring and measuring results),
• A structuring of energy budget decisions .
A lever for CSR transformation
• ISO 50001 is part of the logic of continuous improvement and strengthens the overall environmental approach,
• It enables the mobilization of all stakeholders, both internally (occupants, maintenance) and externally (service providers, suppliers).
Feedback from La Poste and Sobre Energie
In 2020, La Poste initiated an unprecedented ISO 50001 certification process across a portfolio of 196 tertiary buildings, representing an unprecedented scale of 848,000m2 , supported by Sobre Energie.
Among the keys to success:
• Establishment of centralized energy governance and committed regional teams,
• Use of the DATAMARC NEO for real-time monitoring and analysis of consumption,
• Standardization of energy action plans adapted to site typologies.
A concrete example of mass energy performance in the service of a low-carbon trajectory.
Best practices and prerequisites for ISO 50001 certification
Success factors identified by the AFNOR study (April 2024)
• Strong management commitment (key factor for 86% of certified people),
• Creation of an energy team or an identified referent,
• Training and awareness of internal stakeholders,
• Monitoring tools to manage consumption, detect deviations, and measure gains.
The key role of an energy management platform
An energy management platform like DATAMARC NEO from Sobre Energie facilitates:
• Automated collection of energy data (multi-site, multi-fluid),
• The development of energy reviews in accordance with normative requirements to prioritize your work,
• Monitoring of energy performance indicators (EPI) in accordance with your real estate strategy,
• Management of your action plan and its effectiveness measurement.
An essential solution to make your ISO 50001 approach more reliable and documented.
Anticipate regulations, structure your low-carbon strategy
ISO 50001 certification is more than just a "stamp" of compliance: it offers a robust, internationally recognized method for sustainably improving the energy performance of your assets.
With the support of Sobre Energie and the use of DATAMARC NEO, the implementation of an EMS becomes a structuring project, aligned with your CSR, financial and regulatory challenges.
