Lower power consumption, costs and emissions with ISO 50001

Worldwide power consumption has doubled in the last four decades. Global energy production is responsible for 60 percent of greenhouse gas emissions which makes energy management essential for companies and organisations: it ensures a sustainable future for our planet and reduces power consumption and energy costs. Do you also want to implement energy management in your organisation? ISO 50001 helps you on your way.

1. What is IS0 50001?

ISO 50001 is the international energy management standard. The standard describes the requirements an energy management system needs to meet and helps organisations use energy more efficiently.

2. Why implement ISO 50001?

ISO 50001 offers guidelines for organisations to systematically control and improve their energy performance to thus combat global warming. The implementation of an energy management system results in lower power consumption, considerable cost cuts and reduced greenhouse gas emissions.

The Facilitair Bedrijf implements smart energy management

The Facilitair Bedrijf supports the Flemish government with building management, facility services, ICT and purchase and construction projects. It wants to play an exemplary role in the field of sustainability, energy and environment. That is why it obtained the energy management ISO 50001 certificate in 2017. Energy management engineer Stefaan De Taeye: “It sets very high standards but is an excellent guideline . Step by step we converted our energy policy into an energy plan which we subsequently implemented and now execute.”

3. Who is ISO 50001 meant for?

ISO 50001 is ontwikkeld voor organisaties die:

  • systematically improve their energy management.
  • establish, implement, improve and/or maintain an energy management system.
  • ensure their energy management is in order and in line with the latest insights.


4. ISO 50001-certificate

An ISO 50001 certificate is not compulsory but companies often choose certification because they want to have their energy management assessed and evaluated based on the standard. And they want to be able to demonstrate this to their customers and third parties.
