Investing in your property – Reducing operational cost and being sustainable
Ask not ‘what can you do for your technology?’ ask ‘what can your technology do for you?’
with apologies to John F Kennedy
Investing in your property – Reducing operational cost and
being sustainable!
Retrofit
Refurbishment
New build
Why sustainable?
Definition
An intelligent building is a dynamic and responsive architecture that provides every occupant with productive, cost effective and environmentally approved conditions through a continuous interaction among its four basic elements: places (fabric; structure; facilities); processes (automation; control; systems;) people (services; users) and management (maintenance; performance) and the interrelation between them.
The CIB Working Group W098 (1995).
Behaviours
• Tidy or untidy • Methodical or haphazard• Good memory or Forgetful
• Lighting, heating and systems – consume energy– control them
• Automation – switch it off• Show results
The ideal
• E1 - Economy = minimising cost
• E2 - Efficiency = making best use of resources
• E3 - Effectiveness = degree of achievement of outcome
• E4 - Efficacy = degree of relevance of outcome.
The goal – 4 E’s

E1 - Economic Drivers
•Increase in building values:•10.9% for new buildings • 6.8% for retrofits
•Increase in return on investment (ROI):
• 9.9% for new buildings •19.2% for retrofits
McGraw-Hill Green Outlook 2011 Report
E1 - Architectural view
Sarah Daly – Governor, Gloucestershire College
E2 - Efficiency
• Reduced running costs– 36%
• Reduced energy bills– 20%
• Lighting control reductions– 30-40%
• Energy cost savings– 10-50%
• Reduction in operating costs– 13.6% for new buildings – 8.5% for retrofits
E2 - Energy efficient buildings
The following features are important:
High levels of thermal insulationNatural ventilation – connected spacesExclude excessive solar gainHigh efficiency lightingIndividual control measuresEfficient systems equipment and appliancesEmploy effective facilities management
Clements-Croome (2007)
E2 - Energy usage (of all energy)
• Energy used to construct buildings– 5%
• Energy used to heat, light and ventilate buildings– 45%
• Edwards (2002)
E3 - Effective
• Reduction of temperature (1oC)= higher productivity (1.8%)
• Productivity increase (0.5%) pay back 1.6 yrs
• RAE reports improvement in productivity (17%)
E3 - Pedagogy
• Worker Performance =
Motivation x Ability x Opportunity
• Tasks - Individuals– Want to do– Capable of doing– Can be done
• Building creates– Physical environment.
E4 - Efficacious
• Sustainable environmental approach
• Reduction in carbon emissions– 15%
• Carbon saving strategies– High potential
• Educational value
E4 - Carbon Trust
• High potential – Building Controls
– Smart metering
– Building fabric• Heating, ventilation• Cooling, integrated design
• Lower potential – Biomass (for electricity generation),
– Nuclear Fusion,
– Solar photovoltaic
Carbon Trust (2001)

The evidenceThe 4E’s ExamplesEconomic Reduction of 24% capital cost (Bowen 2005)
ROI of 10 years (Kelly 2008)Command more rent (Burr 2008)
Efficient Reduction of 36% in running costs (Bowen 2005)Energy bills reduced by 20% (Johnson 2007)Lighting control reductions of some 30-40% (Ratcliff 2008) Identity and Access Management strategy paid for out of efficiency gains (Tizard and Mockford 2008)Energy cost savings between 10-50% (Shapiro 2009)
Effective Small productivity gain (0.1-2.0%) large effect (Woods 1989; Clements-Croome 2000 and 2005)Reducing temperature – higher productivity – 1.8% for every 1°C. (Niemelä et al 2001, 2002; Wargocki and Wyon 2006)Increase in quality of learning as a result of higher productivity (Everett 2009; Bakó-Biró 2007and 2008; Clements-Croome 2008; Wargocki and Wyon 2007;)0.5% productivity increase pays back within 1.6 years (Wyon 1996) 17% improvement in productivity – RAE (McDougall et al 2002)Increased rents by 2-6% (Eichholtz, Kok, and Quigley 2009; RICS 2009)Occupancy rates 4.1% higher (Burr 2008)Higher income growth over 10 years (Baue 2006)
Efficacious Sustainable environmental approach (Edwards 2002)Carbon saving strategies (Carbon Trust 2002)15% reduction in global carbon emissions (Thomas 2009) Focussing on quality of learning (Everett 2009)

Developing a sustainability virtuous circle in Education
“If you cannot measure it, you cannot improve”
Lord Kelvin (William Thomson 1824-1907)
•Occupant culture change?
•The culture change challenge •Buildings influencing occupiers•Occupiers influencing buildings.
So why now?
• Climate change• Its possible now
– Software based (not electronics/hardware)
– Cost of deployment– Affordable– Retrofit or legacy – Scalability
The challenge• The 4 e’s• Silo thinking - different perspectives
– The building– ICT– Occupant’s– Educational
• Government policy– Economic imperative
• Culture change within education– Learner is central – why– Leadership management staff and students
• VLEs and MLEs– Output devices
• Sustainability as an educational goal• Behaviour in buildings –
– electricity – gas – water – waste
The Solution - rationale
• Don’t throw out the baby with the bathwater– maintaining the people controls – – enhancing with electronic controls – extending with culture change
• = virtuous circle– IT as friend not an enemy
• iBMS– multiplicity of systems controlling the building
environment
• Reducing operational cost– green effects– sustainability goals
• Behaviour in buildings
The solution
• Feedback mechanisms– Hattie
• Management mechanisms– Facilities Management and data
• iBMS – Data input
• KPIs and performance management– Benchmarking and Performance Management – KPIs and Performance Management
• Technology facilitating systems data communication
– MLEs and VLEs– Interoperability and integration
• Business intelligence
– Digital Dashboards

A case study in progress
• Bringing it all together • Using

• to create a virtuous circle
• using dashboard technology
