The revised Energy Performance of Buildings Directive (EPBD) is changing how commercial buildings are managed across Europe. While much of the discussion has focused on energy performance certificates and renovation targets, one requirement is becoming increasingly clear: building owners need better visibility into how their buildings actually use energy.
The EPBD marks a shift from design to operational performance
The revised EPBD, which entered into force in May 2024, is part of the EU's roadmap towards a zero-emission building stock by 2050. Member States, including Finland, are implementing the directive through national legislation over the coming years.
The directive introduces stricter requirements for building energy performance, encourages the deployment of building automation, promotes renewable energy integration, and places greater emphasis on reducing operational energy consumption.
While every building will have different technical requirements, one thing is universal:
You cannot improve what you cannot see.
Energy data is becoming a strategic asset
Traditionally, many commercial buildings have relied on monthly electricity bills or basic energy meters.
While these provide an overview of total electricity consumption, they rarely answer important operational questions:
- Which systems consume the most electricity?
- When do peak loads occur?
- Are HVAC systems operating outside scheduled hours?
- Is poor power quality affecting equipment performance?
- Where is electricity being wasted?
Without detailed electricity data, optimisation becomes largely based on assumptions.
As energy performance requirements become more demanding, access to accurate operational data is becoming a competitive advantage rather than simply a technical feature.
Why real-time monitoring matters
Real-time electricity monitoring transforms raw electrical measurements into actionable operational insights.
Instead of waiting weeks for utility data, facility managers can understand how their buildings perform every day.
This enables organisations to:
- identify hidden energy waste;
- detect abnormal equipment behaviour early;
- optimise peak demand;
- improve power quality;
- verify the impact of energy-saving measures;
- support continuous improvement instead of one-time optimisation.
This aligns closely with the direction of the EPBD, which encourages ongoing building performance optimisation rather than relying solely on periodic assessments.
From compliance to continuous optimisation
Meeting future energy performance requirements is not only about installing new technologies.
It is also about operating existing buildings more intelligently.
Building owners increasingly need reliable operational data to support:
- investment decisions;
- maintenance planning;
- ESG reporting;
- energy management;
- long-term building performance.
Continuous monitoring helps transform energy management from reactive troubleshooting into proactive optimisation.
How eWatt supports smarter energy management
At eWatt, we believe better energy decisions start with better data.
Our Smart Power solution combines proprietary electricity monitoring hardware with advanced analytics to provide high-resolution electricity data every 10 seconds. Unlike conventional energy meters, eWatt offers real-time visibility into electricity consumption, power quality, load behaviour, and electrical anomalies.
The result is practical insight that helps commercial buildings and industrial facilities:
- optimise electricity use without compromising operations;
- identify hidden inefficiencies;
- improve power quality;
- reduce unnecessary peak loads;
- support long-term energy performance improvements.
While technology alone does not ensure EPBD compliance, having detailed, reliable energy data provides a strong foundation for making informed decisions as buildings adapt to future requirements.
Better decisions start with better visibility
The revised EPBD highlights a broader change taking place across Europe's building sector.
Energy performance is no longer measured only by design specifications—it increasingly depends on how buildings operate every day.
Organisations that invest in understanding their electricity use today will be better positioned to improve efficiency, reduce operating costs, and adapt to future regulatory requirements.
Because better energy decisions start with better data.
Frequently Asked Questions
What is the EPBD?
The Energy Performance of Buildings Directive (EPBD) is a European Union directive designed to improve the energy performance of buildings and support the transition towards a zero-emission building stock by 2050. The revised directive introduces stricter requirements for energy efficiency, building renovation, renewable energy integration, and building automation.
Does the EPBD require real-time energy monitoring?
The EPBD does not explicitly require every building to install real-time energy monitoring systems. However, it places greater emphasis on operational energy performance, building automation, and continuous optimisation. Access to accurate energy data makes it significantly easier for building owners to improve efficiency and demonstrate performance.
Why is real-time electricity monitoring important?
Real-time monitoring provides continuous visibility into how electricity is used throughout a building. Instead of relying solely on monthly utility bills, organisations can identify energy waste, monitor peak demand, detect equipment issues early, improve power quality, and make informed operational decisions based on actual data.
How is real-time monitoring different from a traditional electricity meter?
Traditional electricity meters primarily record total electricity consumption for billing purposes. Real-time energy monitoring solutions, such as eWatt Smart Power, provide high-resolution electrical data, including electricity consumption, load behaviour, power quality, and electrical anomalies, enabling much deeper operational insights.
Can energy monitoring help improve building energy efficiency?
Yes. Detailed energy data allows facility managers to identify inefficiencies, verify the impact of optimisation measures, reduce unnecessary peak loads, improve power quality, and continuously optimise building performance without compromising operations.
Which types of buildings benefit from real-time energy monitoring?
Real-time energy monitoring is particularly valuable for commercial buildings, industrial facilities, shopping centres, office buildings, logistics centres, public buildings, and multi-site property portfolios. Any organisation looking to improve operational efficiency and better understand its electricity use can benefit from continuous monitoring.
How does eWatt support organisations?
eWatt combines proprietary electricity monitoring hardware with advanced analytics to collect high-resolution electrical data every 10 seconds. The platform provides real-time visibility into electricity consumption, power quality, load behaviour, and electrical anomalies, helping organisations optimise electricity use, improve operational efficiency, and make data-driven energy decisions.
