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 IT-related

• 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

DATA CENTRE OPPORTUNITIES

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 use our buildings.”

Confronting Inequality: Celebrating Diversity

This is how we did it

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

THE ICT-INTENSIVE LAB

• Compute intensive- simulation and visualisation

• Highly automated• Closely controlled• Tracked in detail• Using e-work methods

SENSING - CONVENTIONAL

• Disadvantages– High first cost– High maintenance costs– Lack of accuracy, esp differential

measurements

SENSING - MULIPLEXED • Routes multiplexed air samples to central sensors

– Integrated into BMS for monitoring & control

– Includes web based data collection & analysis
