What did we explore and how?
Professor Bashroush's work specialises in improving the energy efficiency of data centres, encourages tech organisations to reduce their digital footprints and raises awareness on how our online activity effects the environment.
This has included analysing projects from eBay and other industry leaders to identify new KPIs which measure and calculate appropriate energy efficiency as a significant area for innovation.
Part of his research tackled idle power consumption, where servers consume significant amount of electricity while doing no productive work. Working with Microsoft, Professor Bashroush developed a new modelling technique to approximate the total number of servers needed to run a digital service at a mere 30 per cent overprovisioning level, down from industry average of 300 per cent overprovisioning.
Working with the Pan-European Data Centre Academy (PEDCA) and the European Retrievable Carrier (EURECA), he created a new mathematical model to help optimise hardware refresh cycles which improved performance and computer capacity.
What is the impact of this research?
Professor Bashroush has helped educate the public and led on important conversations around how our digital activity impacts the environment.
His research has shaped and created polices and research programmes on the expert committees that addressed the Green ICT Research and Innovation agenda for the next EU Framework Programme of funding and the All-Party Parliamentary Group on Climate Change work, driving UK data centre sustainability policy.
He has contributed analysis of the largest dataset ever collected on data centres in Europe, covering over 337 data centres, to advise EU legislation for Servers and Online Storage Devices and served on expert working groups.
The work with EURECA has led to primary energy savings of over 131 GWh/year in data centres across Europe, equated to saving over 27 thousand tonnes of CO2 emissions.
He has received extensive media coverage for his work – including a project which showed a single Instagram post by Cristiano Ronaldo uses the same amount of energy as ten UK households.
