Joining Things Up for Buildings | Bill Bordass Presentation Transcript

  • 1. Westminster carbon counting conference, ICE, 24 January 2008
    • JOINING THINGS UP FOR BUILDINGS
    • Bill Bordass
    • the Usable Buildings Trust
    • www.usablebuildings.co.uk
  • 2. “ in theory, theory and practice are the same, in practice they aren ’ t ” SANTA FE INSTITUTE for research into complex systems
  • 3. We need to save real carbon, not virtual carbon
  • 4. “ designers seldom get feedback, and only notice problems when asked to investigate a failure ” ALASTAIR BLYTH CRISP Commission 00/02
  • 5. The Credibility Gap for a green building award winner
  • 6. What needs joining up? Apart from carbon factors, of course!
    • Policy with practice
    • Supply with demand
    • Expectations with outcomes
    • Energy with carbon with environment
    • Landlords with managers with tenants
    • Technology with users and management
    • Top-down (targets) with bottom-up (activities)
    • Organisations with people
    • Government departments and agencies More clarity, fewer incompatible initiatives
  • 7. Don ’ t procure what you can ’ t manage (Unfortunately, regulations are making things more complicated: will they work well in use?)
  • 8. How fast can we improve, if we have been blind to outcomes?
  • 9. Saving energy and CO 2 in a hurry, using the multiplier effect
    • Reduced demands standards, passive measures
    • x 0.5?
    • Increased efficiency better technology, lower resistances
    • x 0.5?
    • Waste avoidance better control, management, behaviour?
    • Less 20%? (it could easily be more)
    • Low-carbon energy supplies on and off-site
    • Halve the carbon content of the supplies?
  • 10. Saving energy and CO 2 in a hurry, using the multiplier effect
    • Reduced demands standards, passive measures
    • x 0.5? 50 %
    • Increased efficiency better technology, lower resistances
    • x 0.5? 25 %
    • Waste avoidance better control, management, behaviour?
    • Less 20%? (it could easily be more) 20 %
    • Low-carbon energy supplies on and off-site
    • Halve the carbon content of the supplies? 10%
    • To get rapid and cost-effective change, we must press ALL the buttons NOT, for example relying on a business-as-usual fix with renewables: they won’t work alone!
  • 11. Use renewable supplies AND make buildings efficient in use
  • 12. Performance Indicators It ’ s not just about carbon!
    • Is the building thermally efficient in use?
    • Is the building electrically efficient in use?
    • Do any special features need considering?
    • What is the effect of on-site renewables? The energy that is used but not imported.
    • What energy supplies are imported?
    • What is the carbon content of these supplies? << This is the main carbon contact point >>
    • Is there any reason for using special C factors?
    • Are any further C-saving measures undertaken?
  • 13. Making Performance Visible with building energy certificates
    • Ambitions of Europrosper
    • research project 2000-04:
    • Display energy certs based on actual energy use. Achieved
    • Transparency between expectations and outcomes. Incomplete
    • Multiple performance indicators Incomplete
    • We now need voluntary supporting measures
  • 14. Passing on the carbon
  • 15. Passing on the carbon and the energy
    • Annual energy and CO 2 emissions statements?
    • Gas and electricity, perhaps even on each bill. Obstructed, but should be coming.
    • District heating and cooling. Potentially could do similar.
    • Lorry deliveries (coal, wood, biofuels, oil, LPG) More difficult because of multiple suppliers.
    • From landlord to tenant. Prototype already produced for offices.
  • 16. Passing on the carbon BPF Landlord ’ s statment
  • 17. Passing on carbon + energy BPF Landlord ’ s statement
    • Improves transparency
    • Includes multiple performance indicators
    • Allows individual tenants to add the energy they purchase directly and prepare Display Energy Certificates on same basis as whole buildings.
    • Avoids double handling if it allows the transfer of carbon from landlord to tenant for the purpose of the Carbon Reduction Commitment.
    • Interest being shown by other sectors (business centres, retail, industrial
  • 18. Passing on carbon + energy BPF Landlord ’ s statement
  • 19. Drilling down further to assign realistic priorities
  • 20. Drilling down even further: actual versus predicted for lighting
  • 21. Avoiding unintended consequences
    • Focus on supply, maintains business-as-usual illusion.
    • “ Low-carbon” fuels become the easiest solution. Waste precious resources and do not tackle underlying demand.
    • Dash to biomass. Massive ecological damage potential.
    • Pushing unproven solutions. Danger of tripping over.
    • Creating complicated solutions. People won’t cope.
    • Creating expensive solutions. We need the quick wins.
    • Requiring too much maintenance. It won’t be affordable.
    • Too much bureaucracy, multiple layers and confusing differences. Focus resources on getting things done.
    • Not involving individuals. Everybody has to help.
    • We trade too early. Charity begins at home!
