OUR AUDIT EXPERTISE

SEME NEXTEP Platform , BACS Decree, Energy Optimization, Energy Procurement

WHAT IS THIS

Don't let the savings disappear after the renovations 

In practice

  • For whom?

    Any organization that has carried out energy efficiency work or deployed a BMS

  • Earnings

    5 to 15% additional savings within 12 months of deployment

  • Compliance

    Compliant with the Tertiary Decree, ISO 50001 and CSRD — traceable data

  • Monthly deliverable

    Report including indicators, gaps vs. objectives, and operational recommendations

After an energy renovation or the deployment of a BMS, consumption can gradually drift if no active monitoring is put in place. 

Powesco's energy optimization relies on monthly support from a dedicated Energy Manager. Data analysis, anomaly identification, adjustment recommendations, and action monitoring ensure sustained performance over time. 

  • Monthly analysis of consumption and detection of discrepancies
  • Detection of anomalies and faulty equipment (< 24h)
  • Monthly report with prioritized operational recommendations
  • Monitoring implementation and measuring impact
  • Data traceability for ISO 50001 and CSRD reporting

What energy optimization brings

  • 5–15%

    additional post-construction savings

  • < 24h

    anomaly detection

  • ISO 50001

    Structured and documented SME

  • CSRD-ready

    traced energy data

What you get

A managed service comprised of 5 monthly components 

Each month, the same rigorous cycle — collect, analyze, detect, recommend, measure impact.

  • Data collection and quality control

    Verification of the completeness and consistency of consumption data. Detection of faulty sensors or measurement gaps. Correction before analysis.

  • Analysis of consumption and discrepancies

    Comparison of actual consumption with targets and historical benchmarks. Identification of areas of overspending and quantification of unrealized savings.

  • Detection of anomalies and faulty equipment

    Analysis of load curves to identify equipment operating abnormally: nighttime overconsumption, occasional overshoot, regulation faults. Alert within 24 hours.

  • Monthly report with actionable recommendations

    Structured document: results for the month, deviations from objectives, anomalies detected, prioritized adjustment recommendations with estimates of recoverable gains.

  • Monitoring implementation and measuring impact

    Verification of the implementation of the previous month's recommendations. Measurement of the impact of the adjustments made. Updating of objectives if necessary.

THE EXPERT'S WORD

Data does not createsavings 

Monitoring without active optimization only recovers 30% of the potential. Data is only valuable when it informs decisions. That's where we come in. The monthly report isn't a data report—it's an action plan for the following month.
