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
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.
