Energy optimization with BACS: waiting is a risk, investing now is an opportunity

Uncertainty around the new BACS regulation (Building Automation and Control Systems) is creating unrest in the real estate sector. Many property owners and managers are taking a wait-and-see approach, but doing nothing is not the safe option. On the contrary: it is a risk, while the upside of taking action is compelling. In this blog, I explain why.

Cutting through the regulatory fog

European and national sustainability regulations are evolving at a rapid pace. The BACS requirement, the Dutch implementation of the European EPBD IV directive, is a clear example. From the start of 2026, Dutch non-residential buildings with an installed capacity above 290 kW must be equipped with smart control systems that automatically monitor and optimize energy use and are interoperable with other building installations.

On paper, this makes sense. In practice, however, there is still a great deal of uncertainty. The regulation is technical, layered and insufficiently clarified. For example, it remains unclear who will be responsible for enforcement. In addition, the term “interoperable” raises practical questions. Finally, the exact requirements for mandatory data monitoring have yet to be clearly defined.

Why waiting is not an option

Because of this uncertainty, many organisations are currently holding back. In particular, the control systems (CS) component of BACS still requires further clarification from the authorities. In the short term, waiting may feel safe. In reality, it is a false sense of security.

  • First, inaction increases the risk of value erosion. The regulation is not being postponed and is expected to become more stringent over time. Buildings that no longer meet sustainability criteria or ESG reporting requirements risk losing value and face a serious threat of becoming stranded assets.
  • Second, specialist expertise is scarce. As a result, entering late almost always leads to higher implementation costs and reduced strategic flexibility.

A positive business case for BACS

The business case for investing is strong. The technology is available and the numbers speak for themselves. In a large office building in Amsterdam, a relatively modest investment resulted in an 18% reduction in energy consumption, without compromising occupant comfort. As a result, the building already meets targets that were originally set for 2030, simply through smarter energy management. In addition, payback periods are short. In many cases, investments are recovered within a year. In some cases, even within a matter of months.

From compliance to competitive advantage

More importantly, advanced building energy optimization software such as our BRIGHTER solution goes beyond regulatory compliance. It identifies where energy is being wasted, optimizes HVAC performance and continuously aligns building systems using installation data, weather data and occupancy patterns.

The result is an average annual energy saving of 28%, combined with lower CO₂ emissions. By investing now, you not only avoid unnecessary risks and ensure compliance, but also gain a clear competitive advantage. You stay ahead of climate regulations, while sustainability investments increase asset value and make buildings more attractive to tenants.

Buildings are becoming energy assets

This competitive advantage extends beyond short-term value creation. Increasingly, real estate is evolving into energy assets. The growth of batteries, solar PV, electric vehicles and the electrification of heating systems is making building electricity profiles far more dynamic. At the same time, buildings are becoming active participants in the wider energy system.

In practical terms, this means that energy production and consumption are balanced more intelligently. Buildings contribute to grid stability and, by participating in energy markets, unlock new revenue models.

In summary, buildings are increasingly functioning as virtual power plants: smart, self-regulating energy hubs that support grid stability, reduce CO₂ emissions and generate new income streams through flexibility markets. Integrated energy management systems are essential to enable this. With our BRIGHTER platform for building optimization, we enable that future.

Accelerating toward future-proof real estate

Although the BACS regulation has not yet been fully clarified, the conclusion is clear. Smart building optimization is not a burden, but an opportunity. Compliance with BACS is no longer optional. The timing of action, however, still is.

By starting now, you work towards a future-proof portfolio that not only preserves value, but actively creates it. Begin by viewing your building as an active player in the electricity market. In doing so, we can accelerate the transition to future-proof real estate in the Netherlands, meeting sustainability goals while contributing to grid stability. With smart solutions like BRIGHTER, the first steps are straightforward: gain insight, optimize and automate.
