How ICT can Create a
Leaner and More
Sustainable Estate
www.goodcampus.org
THE ESTATES CHALLENGE
• Low utilisation
- of (often expensive) space
- of equipment
• High operational costs
- especially highly serviced space
- much inefficiency and wastage
• Dysfunctional space
- infrastructure, interaction, noise etc.
• Inadequate budgets and capacity
ESTATES AND IT
• IT as key factor in building layout and
energy/thermal performance
• Estates providing support services to IT
- space, conduits, cooling, power supply
• IT supporting Estates hardware/software
• Estates running vendor supported systems
- Building Management System, dashboards
• Estates providing MIS data e.g. space
• IT apps supporting Estates environmental
responsibilities e.g. travel, waste
IT AND ENERGY/THERMAL
PERFORMANCE
• 20-25% of non-residential electricity is ITrelated
• IT is 17% of Cambridge Chemistry Lab’s
£700,000 electricity bill
• IT can be 50% or more of heat load in
today’s buildings
• IT electricity usage can easily be reduced

TOTAL COST
“The GSA realises that the smartest part of smart
buildings is people and wants to engage them.
Providing feedback and information through a
dashboard is a good start. With smart technology,
we can learn anything we want about a building
and optimise its performance. But real performance
means happier, more productive tenants. And that
requires insights into the hearts and minds of the
people inside. What a dashboard can really do is
enable better decisions, inspire participation, spread
knowledge and best practices, communicate at a
human scale and propagate new norms in how we
This is how we did it
Confronting Inequality: Celebrating Diversity
PILOT FEEDBACK
WORKPLACE ENERGY MONITORING
• Complicated
presentation of
energy data
• Limited interaction
• Closed systems with
no social data sharing
• Limited online
applications
• Bound to proprietary
software, usually
technical
ENERGY FEEDBACK PROTOTYPES
Prototypes are online consuming live energy data
PROJECT DELTA
• Lab ventilation costs HE
c. £150 million pa
• Fume cupboards use
£1000-2000 of energy pa
• Aim: Display and
reporting of usage data to
influence user behaviour
