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?’

Investing in your property – Reducing operational cost and

being sustainable!

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
