Energy calculator for SMEs and large organisations

Many businesses underestimate how decisive their energy consumption is when it comes to legal obligations. Are you energy‑intensive or not? Do you need to draw up an energy plan, commission an audit, or is an energy balance sufficient? Sweco’s energy calculator provides a reliable answer in just a few minutes – without having to wade through complex regulations or do the calculations yourself.

Instant clarity on your energy obligations

This tool is designed to give businesses rapid insight into their annual final energy consumption, fully in line with Flemish regulations. That makes it not only practical, but also strategically valuable. You immediately know where you stand, which steps are required to remain compliant, and where opportunities might otherwise be missed.

How the calculator works in practice

The calculator starts from data that every business can easily access. You indicate whether you are an SME or a large organisation and enter your annual energy consumption per energy carrier. This may include electricity, natural gas (high or low calorific value), or gas oil.

Behind the scenes, the tool automatically converts these figures into final energy consumption, with each energy flow correctly calculated based on its energy content. All consumption is consolidated into a single total, expressed in petajoules (PJ) per year.

This total is crucial. Once the threshold of 0.1 PJ is exceeded, you are classified under the regulations as an energy‑intensive organisation. If you remain below it, a different category applies. The calculator makes this distinction immediately clear, leaving no room for interpretation or doubt.

Instantly understand what this means for your business

What truly sets the energy calculator apart is that it goes beyond delivering a single figure. Based on your energy consumption and the type of organisation, it immediately indicates which study applies to your situation. This could be an energy plan, an energy audit or an energy balance.

In this way, you avoid incorrect assumptions and know exactly which obligations apply – as well as which pathways may be of interest to further improve your energy efficiency. For many businesses, this is the first clear starting point towards structural energy savings and a future‑proof energy strategy.
