Computer Room Efficiency Improvement Greening ICT project with JISC 23 rd of September 2011

Carbon Management Board, September 26 th, 2011 Page 2 Objectives Reduce power consumption in Computer Rooms by 5% a year using a combination of measures: Air-to-air cooling units (“free” cooling)– more efficient room cooling Cold aisles inside the rooms – more efficient equipment /racks cooling Windows films/replacement, UPS downsizing, efficient lighting – reduce heat generation Miscellaneous – adjustments to cooling units Share experience with educational sector and offer a project role to Imperial students. Follow best practices outlined in EU Code of Conduct for data centres. In cooperation with
