  • A uniform structure that facilitates the combination with other standards.
  • Improvement of the energy balance and the reduction of CO2 emissions.
  • Increased efficiency and lower energy costs.
  • Transparency in optimising the energy rate.
  • Raising employees’ awareness of more efficient energy use.
