Geoff Constable – ‘How Green was my Video Conference’
Rob Johnson – ‘Automated power-up/down’


Geoff Constable has an MSc from the Computer Science Department at Aberystwyth University. He has worked for the Welsh Video Network, which supports public sector videoconferencing, for 10 years. He is also a member of the JANET Video Technologies Advisory Service which offers independent advice to JANET connected organisations.

This talk describes the work and findings of a JISC ‘Greening ICT’ project: “How Green Was My Videoconference”. This project researched the carbon footprint of producing and using videoconferencing equipment, and contrasted that with the potential for reducing carbon emissions by replacing travel with videoconferences. The work also looked into ways of making the technology ‘greener’ which include programming control systems to put studios into stand-by, switching equipment off, and maximising usage.

Rob Johnson graduated from Aberystwyth University in 1999 with a BSc (Hons) in Computer Science. He has been working as a Systems Engineer and Developer within the Information Services since 2007. He specialises in Java Development.

PAWS is an acronym for “Power and Wake System” which is a PC Power Management solution that has been developed by Aberystwyth University with the support of JISC. Rob Johnson, the Project Manager and developer of PAWS will be introducing this new open source centrally controlled solution that offers remote computer waking and sleeping capabilities and production of utilisation and estimated power saving statistics.

The videos of the presentations are available via the links below.
