Data Centre AirflowIt is estimated that 50-80% of valuable conditioned (cooled) air does not reach the intake of IT equipment due to unsealed floors and openings.

Data Centre Airflow40% Annual Energy Savings in AS3 Data Centre, with more savings attainable.
Ambient temperature drop from 24 °C to 16°C
Change of 8 degrees
Lowered Air Conditioning demand to raise temperature back to 24°C
Estimated 40% Annual Energy Saving
Further 2°C change estimated!
Savings paying for HPC Chiller!

Earthing & BondingA server rack with 8 servers generates 10 mA-20 mA leakage currents – 50 mA is enough to kill.
Organised the appropriate earthing and bonding of each rack in AS3 DC.
Liaised with external Electricians
Organised access
Ensured job was completed without downtime
Each network rack now has the appropriate earthing ensuring a safe environment.

Data Centre: Cabling Refresh
5/5
Rework the way data cabling is connected.
![Page 18: Aaron Barwick Data Centre Portfolio](https://reader033.vdocuments.net/reader033/viewer/2022051720/58ed21481a28ab31568b4713/html5/thumbnails/18.jpg)
Cabling Refresh“The decision to place network data and power cabling into overheadcable trays can lower cooling fan and pump power consumption by 24%.” Schneider Electric
Under-floor cabling contributes to energy losses in three ways:
• Blockage of air due to cables
• Bypass air from rack cable cut-outs
• Bypass air from (PDU) cut-outs
Liaised with external contractors
Organised access
Ensured job was completed without downtime
Each rack now has 24 port copper and fibre patch panels back to one central location.
