Energy management

Systematic reduction of energy use based on NS-EN ISO 50001.

Energy management keeps consumption down in large property portfolios over time. We design and run the system to NS-EN ISO 50001.

Key elements

Why it works

Standalone measures deliver a one‑off effect. A system finds new deviations, follows measures through to operation, and builds organisational learning. Improvement becomes continuous, not project‑based.

We can operate the system in the initial phase while training the internal organisation in parallel.

Questions and answers

Do we need ISO 50001 certification?

No. Many owners adopt the ISO 50001 method to get the results without pursuing formal certification, while others certify because customers, lenders or reporting frameworks expect it. The savings come from the system, not the certificate.

What is an energy baseline and an EnPI?

The baseline is the reference level of consumption, normalised for weather and occupancy, against which performance is measured. Energy performance indicators (EnPIs) such as kWh/m² track whether you are actually improving against that baseline.

How is this different from a one-off optimisation?

Standalone measures deliver a one-off effect. A management system finds new deviations every month, follows measures through to operation, and builds organisational learning, so improvement becomes continuous rather than project-based.
