Ready for energy legislation with a building management system
A building management system (BMS) is no longer optional: for many non-residential buildings, it will become mandatory by the end of 2025 to actively monitor and optimise energy consumption. Many existing systems do not yet meet these requirements. Through a BMS analysis, Encon helps determine what is needed to make buildings energy-efficient and future-proof.
What is a building management system and why is it important?
A building management system (BMS) or BACS controls and optimises technical installations such as heating, cooling, ventilation and lighting. It ensures that these systems work together intelligently, tailored to usage, occupancy and external conditions.
When a BMS is set up correctly:
- your energy consumption is reduced on a long-term basis
- you gain insight into performance and deviations
- you increase comfort levels in your building
- you comply with stricter energy standards
New regulations explicitly refer to the EN ISO 52120 standard, with Class B being regarded as the benchmark for energy-efficient buildings.
Where do you stand today? Start with a BMS GAP analysis
Many organisations are unaware of the extent to which their current building management system complies with this standard. This is precisely where the added value of a BMS GAP analysis lies.
Encon analyses your existing installation and compares it with the requirements of EN ISO 52120. This gives you a clear picture of:
- your system’s current performance
- missing functionalities
- specific opportunities for improvement
This approach forms the basis for targeted investments, without unnecessary costs.
Our approach
We work in a structured and pragmatic way, so that you gain insight quickly and can make targeted decisions.
We start with thorough preparation and collect the relevant data on your building and installations. During a site visit, we examine how your systems currently function and how they interact with one another.
We then map out the current situation and assess it against the criteria of EN ISO 52120 Class B. Among other things, we analyse the automation of HVAC, lighting and other technical installations, and examine monitoring and control strategies.
Based on this, we identify areas for improvement. These can range from optimising settings to implementing more advanced control systems or expanding your system.
Finally, we translate this into a concrete action plan, including priorities and investment areas. You will know exactly what steps are needed to become compliant and improve performance.
The added value of a building management system
Adapting a BMS to comply with legislation is one thing. Using it intelligently to improve your energy performance is where the real value lies.
By optimising your building management system:
- you reduce operational costs
- you improve control over your systems
- you prepare your building for future requirements
- you create a stable foundation for further digitalisation and data analysis
So you’re not just investing in compliance, but also in structural efficiency.
Why Encon?
Encon combines in-depth technical knowledge with expertise in energy legislation and strategic guidance. We look not only at the technical aspects, but also at feasibility, budget and impact.
You benefit from a single, integrated approach, with experts who know how to translate complex systems into concrete improvement measures. This helps you avoid fragmented solutions and work in a targeted manner towards achieving results.
