    • West of England Carbon Challenge
    • Carbon Swap Shop • Learn of successful CO2 cutting projects, and what to apply to your own organisation • Overcome challenges in your organisation to making progress
    • AgendaTime Session8.30 Welcome and Introductions 1st 3 pitches: Avon Fire, At-Bristol, Bevan Brittan Q&A 2nd 3 pitches: Buro Happold, CODA Architects, Env Agency Q&A and reflections Surgery style challenges in groups Report back and networking
    • Questions What’s your current challenge? What do you want to learn/talk about?
    • Avon Fire & Rescue Service
    • Boiler Controls
    • Voltage Optimisation Savings guaranteed 9.5% Savings achieved 4.7%
    • Staff Engagement
    • Collaboration
    • CO2 Emissions ReductionRobert StanleyDirector Property and Facilities27 September 2012
    • The Project• To reduce CO2e year on year• Baseline Energy Consumption 2,043MWh pa• 2011/2012 Energy Consumption 1,669MWh pa• Carbon Savings - Base Year 251tCO2e - Previous Year 111tCO2e
    • The Cost• Recent Initiatives: - Car park extract fans install CO2 detectors Cost £14k Savings £21k pa - Replace lights with new energy saving lights Cost £6k Savings £3k pa - Replace hand dryers with more energy efficient Cost £20k Saving £10.5k pa - = Return on investment 15 months
    • Unexpected Outcomes• Easy quick wins• No resistance from Finance Director• Wish we had known about Smart Meters, ability to obtain half hourly meter readings combined with data from our sub meters.• The tour !!
    • Buro Happold Buro Happold Buro HappoldCarbon Reduction
    • Buro HappoldCamden Mill, Bath (400 staff) Achieved 14% reduction in CO2e between 2010 & 2011  Removal of 10 server boxes and making these virtual servers which has meant that they were using 5% energy of previous  Installation of about 18 PIR (passive infra-red) sensors for lights (@ less than £20 each) in common stair areas (working off movement and light)  Implementation of power saving settings on all computers so that monitors turn off after 10 minutes of inactivity.
    • Buro HappoldServer Virtualisation Server Virtualisation  Annual Energy saved = 54 MWh (£5562)  Servers at end of useful life (5 – 6 years)  Cost of traditional replacement = £40000 (Capital cost and maintenance)  Actual cost of server virtualisation = £16000 (Capital Cost & maintenance)
    • Buro HappoldPIR Motion and Daylight sensors PIR Motion and Daylight sensors  Annual Energy saved = 4 MWh (£400)  Installation of about 18 PIR (passive infra-red) sensors for lights in common stair areas (working off movement and light)  Cost = £36 per PIR (£18 plus installation)
    • Buro HappoldPower Saving Settings on Monitors Power Saving Settings on Computer Monitors  Annual Energy Saving = 5-6 MWh (£600)  Implementation of power saving settings on all computers so that monitors turn off after 10 minutes of inactivity.  Implemented using MS SCCM – acquired to roll-out new applications to all computers – but also provides central control of power saving settings over our internal network
    • Buro HappoldUnexpected outcomes and learningServer Virtualisation Positive – more space and less noise Negative – not possible with all applications (i.e. Dongle licences)PIR Sensors Positive – adjustments available – light level and time on Negative – gradual approach – not all at onceComputer Monitors Positive – nobody complained! Negative – actually not quite true – some engineers running long programmes complainedWe could have done some of this stuff earlier.
    • Buro Happoldwww.burohappold.com
    • IntroductionCODA Architects• Medium sized Architectural practice• Bristol Based, operating nationally• Health, retail, Hospitality and education• Projects from £100K to £100million• Award Winning• Collaborative and Ethical Approach
    • What was the project?Coda Green Guide• A Sustainable – in house, Design Guide• Sharing our knowledge and plugging any gapsTeam Project involving:• Workshops• Individual study• Presentations• Discussions
    • What did it cost?What are the expected energy/carbon/cash savings? Cost: • Time Indirect Savings: • Time - Efficiency of Design / work process • The buildings we design are more energy efficient • Our staff are more aware of Green Issues and therefore more engaged in cutting carbon
    • Were there any unexpected outcomes of this project? (both positive and negative) Staff Engagement • Better understanding of the issues and the need for change • A willingness to accept other office wide initiatives • Taking initiative and proposing better ways of working
    • What do you now wish you had known when you started?• Keeping the information up to date is a challenge• It hasn’t increased our ability to influence decisions as we had hoped it wouldWe should have done it sooner
    • Sustainability
    • Energy Monitoring System138 sensors throughout the buildingConstantly recording energy usage of everyelectrical appliance 24 hours a dayAll data processing done in-houseAn invaluable tool for reducingconsumptionApprox £8,500 Sustainability
    • Typical daily usage Sustainability
    • Culture Change across the organisation• Energy Reduction Group – 8 key staff• Using energy data to make better use of the building, to eliminate unnecessary usage and reduce necessary usage• Improving departmental procedures, the way activities are planned and the way spaces are used• Introducing new duties for key departments and individuals• Creating an environment where every member of staff is constantly aware of the energy that they are using and encouraging and enabling them to reduce it Sustainability
    • Energy in ƒ At-Bristol Energy Consumption 200000 180000 160000 140000kilowatt hours 120000 100000 80000 60000 40000 20000 0 r t ly il r r ry ne ay r y ch us be be be be r ar Ju Ap a M Ju ar g m ru nu m m o Au M ct te b e e Ja O Fe ov ec p Se N D 2009-2010 2010-2011 2011-2012 Sustainability
    • The next step in energy reduction: Our 50 kWp photovoltaic arrayLarge enough to power 11householdsProviding 3.2% of our annualelectricity useMeeting 20% of the building’sneeds at peak performanceSaving 25 tonnes of CO2 peryearCurrently performing 7.5%above predictionsFunding grant from EDFLinks to our educationalprogramme Sustainability
