Energy-saving schemes

The energy consumption in server rooms is high: not only due to the energy consumption of the servers themselves, but also due to the cooling required to compensate for the heat produced.

The energy consump­tion of a server room can amount to ⅓th of the elec­tric­ity consump­tion of an office. The elec­tric­ity consump­tion of 1 square meter computer center is compa­ra­ble to the use of an average house­hold: approx­i­mately 3,000 kWh per year.

Below you will find an overview of the energy saving measures, first for primary server equip­ment and then for cooling the server room. 

Install power management on the server

This line is part of the SIC DcIC certificate.

With power manage­ment, the clock speed of the proces­sor can be adjusted depend­ing on the number of calcu­la­tions required per second by the proces­sor. Due to power manage­ment, the proces­sors do not work contin­u­ously at full clock speed. 

Other energy saving measures:

  • Outsource your data storage

  • Make optimal use of ICT capacity

  • Virtu­al­ize servers

  • Pay atten­tion to energy effi­ciency when purchas­ing servers

  • Choose an energy-effi­cient UPS

  • Use power and cabling that complies with TIA 942

  • Measure the energy consump­tion of auxil­iary equipment

  • Work with certi­fied installers

Energy measures for cooling the server room

A lot of heat is released when process­ing data. Cooling off this heat costs on average 25% of the total energy consump­tion of the server room.

  • Extract heat at source in small server rooms
  • Provide cold and warm corridors
  • Close unused posi­tions in the racks with blind panels
  • Set climate zones
  • Prevent loss of cold air
  • Increase server room indoor temperature
  • Apply Free Cooling
  • Limited speed fans in room coolers server room
  • Choose an energy-effi­cient cooling machine
  • Reuse the heat produced by the ICT equip­ment (this scheme is being further devel­oped by the save energy foundation)
  • Use PCMs
  • Get a white or reflec­tive roof

All these schemes are explained in more detail on Stim­u­lar. The Stim­u­lar Foundation’s mission is to accel­er­ate the sustain­abil­ity of compa­nies and orga­ni­za­tions by sharing knowl­edge and experience.
