EPBD IV: what the amendment to the Dutch Environmental Regulation from 29 May 2026 means for your real estate portfolio and projects

This article covers the Dutch implementation of EPBD IV (Energy Performance of Buildings Directive). Per 29 May 2026, the first tranche of this implementation enters into force through an amendment to the Omgevingsregeling (Environmental Regulation). The changes affect both new construction and existing non-residential buildings and have direct consequences for energy label scores, mandatory building systems, and the transparency of energy performance towards financiers and tenants.

This article explains what is changing and what it means in practice for real estate investors, housing corporations, and developers.

1. New energy label A0 for emission-free new construction

From construction year 2026, a separate energy label will be introduced for emission-free new builds: A0. A building qualifies as A0 if it meets three cumulative requirements:

• No fossil emissions on site (no gas)

• Primary fossil energy use at least 10% below the BENG 2 standard

• Sufficient renewable energy production on or near the building

The A0 label thus becomes the new benchmark for new construction in the institutional market and aligns more closely with the EU Taxonomy. Investors currently developing new build projects or considering acquisitions should adopt this label as a minimum standard. The difference between an A++ and an A0 will become increasingly visible in financing conditions and tenant expectations in the coming years.

2. BACS requirement: building automation becomes mandatory

One of the most impactful changes is the introduction of the mandatory Building Automation and Control System (BACS) standard, based on NEN-EN-ISO 52120. The obligation applies to non-residential buildings with a heating or cooling installation above a certain threshold:

• From 1 January 2026: buildings above 290 kW (broadly corresponding to medium to large distribution centres and large office complexes, large retail properties such as shopping centres, and large hotel complexes).

• From 2030: buildings above 70 kW (e.g. small standalone supermarkets, care facilities, schools and small office buildings, small retail properties).

The minimum requirement is class C for general automation (control of heating, cooling, ventilation, lighting, and solar shading) and class B specifically for energy consumption and indoor climate reporting.

Class C requires, among other things:

• Individual electronic temperature control per room

• Outdoor temperature-compensated control of distribution networks

• Time-controlled ventilation

• Automatic motorised solar shading (or a demonstrable equivalent)

• Central fault detection

Class B for energy analysis requires that historical energy consumption data per system is retained, trend analysis across multiple periods is possible, and deviations are flagged. This goes beyond simply reading meters. The BMS must be read and analysed in more detail.

The 5% correction factor: when the BACS requirement is not met

Buildings that fall under the BACS obligation but are non-compliant will have a correction factor applied in the NTA 8800 calculation that worsens the calculated energy performance for heating and cooling by 5%. This translates directly into a lower energy label score. For portfolios with an active label improvement programme or Green Finance Framework, this is a measurable risk.

In practice, the most common compliance gap is the following: older building management systems log data but offer no trend analysis or reporting based on historical comparison. This is solvable without full system replacement. Most systems can be read remotely with limited modifications, and by connecting them to the right energy management platform, the necessary requirements can be met.

3. Energy storage rewarded in the energy label

The amendment also includes a positive incentive: battery storage with demonstrably sufficient capacity (>5 kW) leads to a reduction in the EP2 value in the NTA 8800 calculation, provided the building also generates electricity locally (for example via solar panels).

Investors who have already invested in PV and batteries can benefit from this. Adding battery storage may not only be operationally attractive but also relevant from a label perspective. This makes it worthwhile to include such investments in the roadmap analysis per asset.

4. Abolition of mandatory inspection requirement

The mandatory periodic inspection of heating and air conditioning systems is being abolished. Buildings with a BACS that meets the standard are automatically exempt. The expected saving for the Dutch real estate market is €14 to €18 million per year.

In practice, the BACS obligation functionally replaces the inspection requirement: continuous monitoring and (automatic) control provides more insight into system performance than a periodic inspection. Buildings without a BACS also lose the inspection obligation, but will then face the 5% correction factor.

5. More comprehensive energy label

The energy label will be expanded with additional information that increases transparency for all parties involved:

• Operational CO2 emissions in kg/m²/year

• Final energy consumption

• On-site renewable energy production

• Remaining service life of installations

This makes the energy label more informative than the current label class alone. Comparison between assets becomes easier for tenants and buyers. For investors, it means that weak performance on individual components will become more visible, even if the overall label class remains acceptable.

6. Expanded access to the EP-Online database

From 1 July 2027, three new categories of parties will gain direct access to more energy label data in the EP-Online database, without requiring the owner's consent:

• Financial institutions (mortgage providers, financiers)

• Municipalities

• Commercial tenants

Energy label data will be retained for 15 years. This structurally increases transparency and makes energy performance a standard component of due diligence in acquisitions, financing, and lease negotiations.

What this means for your portfolio

The amendment to the Environmental Regulation requires action at multiple levels.

Short term (2026): Identify which buildings exceed 290 kW and conduct a BACS readiness scan (class C). Focus in particular on energy monitoring (class B), as this is the most common gap in existing portfolios.

Medium term (2027): Prepare for changes to energy label scores (BACS, storage, and A0 label). Incorporate this into your acquisition and disposal due diligence processes, and map the impact on your current portfolio to ensure continued compliance with energy label obligations and targets.

Structural (2030): The extension of the BACS obligation to buildings above 70 kW affects a large part of the non-residential stock. Multi-year plans for BACS implementation need to be developed now, not in 2029.

How Cooltree supports you

Cooltree supports institutional real estate investors in translating this regulation into portfolio policy and concrete action plans. We do not carry out technical building scans or label certification processes, but we analyse the impact of the new obligations on your portfolio and acquisition policy, and help you develop an approach that aligns with your ESG strategy, investment horizon, BMS data analysis (as part of the BACS obligation), and reporting requirements.

Our services on this topic include:

• Portfolio analysis: insight into which assets are affected by the BACS obligation and the NTA 8800 correction factor, broken down by deadline (2026 and 2030) and risk profile

• Impact assessment: translation of non-compliance into effects on energy label scores, EU Taxonomy alignment, and financing conditions

• Strategy and prioritisation: a portfolio-level approach indicating which assets deserve priority, which measures deliver the most value, and how this fits within existing sustainability programmes

• Reporting: integration of BACS status and energy performance into broader ESG reporting
