CRITICAL ENVIRONMENTS features into their facilities , Kao Data ’ s Harlow campus was conceived from day one as an exercise in marrying its substantial HPC capabilities with sustainable practice .
“ Kao Data London-One ( KDL1 ) was specifically designed to cater for the most power and compute-intensive workloads , and to be able to power and cool them in the most environmentally sustainable and energy-efficient way ,” says Myall . “ Central to this was the use of Future Facilities Computational Fluid Dynamics ( CFD ), which allowed us to both model and simulate our technical suites under a number of operating conditions . The findings enabled us to fine-tune performance and airflows , ensuring we could prioritise sustainable operations and were instrumental in helping us support Cambridge-1 .” As a result , the campus runs at a consistent PUE of 1.2 , even at partial loads ( well below the industry average - particularly considering the density of its IT architecture ), is powered entirely by renewable energy , and uses mechanical and refrigerant free indirect evaporative cooling .
While Myall explains that the Harlow campus typically uses this indirect
