• Social
• Financial

• Cut out worst practice
• Require better practice via planning system
• Bad buildings (high economic costs)
• Bad a/c units
• Bad appliances
• MEPS energy water
• Pricing reforms
• Price signals, peak costs
• Raise awareness

  energy water requirements ? encourage beyond
  compliance

15
The gaps (5 6)

• Group 6

  with the correct drivers for energy efficiency
• Internalising externalities, eg carbon credits
• Minimum compliance codes
• Regulation which is outcome driven eg energy
  usage/m2 maximum
• Benchmarking / market drivers

• Group 5
• Widespread knowledge of the available emerging
  technologies. Not just hard tech but systems
  approach. Eg flows in buildings
• Delivery process is not conducive to energy
  efficiency
• Entrenched attitudes
• Tradition
• Design as commodity (fee bidding)
• Owner/manager/operator/tenant/user relationships
  not properly understood and used
• Integrated project delivery
• Not sequential as not
• Not add on
• Capital for retrofit
• Rethinking retrofit eg a building related energy
  services company
• True cost of energy!!! Currently missing

16
summary

• Opportunities
• Benchmarking
• Education/information feedback
• Technology - Intelligent materials,
  refurbishment, maintenance, better controls
• Incentivise (change behaviour financial,
  environmental, targets eg zero energy building)
• Needs
• Economic instruments - eg better pricing
  signals, incentives, regulations
• Managing peak and base loads
• Cut out worst practice
• Gaps
• Building related energy services co (outsourced),
  including retrofit
• Internalising externalities true cost
• Minimum compliance codes
• Regulation outcome driven
• Benchmarking/market drivers
• Knowledge of available/emerging technology
• Delivery process is not conducive (design as a
  commodity)
• Stakeholder relationships
• Integrated project delivery

• What signals are the drivers (incentives) for
  adoption
• Targets/benchmarking
• Education info availability
• Delivery system
• Intelligent systems

17
Opportunities for TWC

• Innovative financial and technical solutions
  Regulatory and pricing reform (incl linking
  building planning and network planning)
• Benchmarking good practice
• Communication - uniting common interest groups
  and key stakeholders to champion the message
• Technology innovative options to leapfrog to
  best practice
• More value from existing technology / novel
  applications
• other ???

18
Suggestions

• Use TWC approach to make case for regulatory and
  pricing reform, based on new thinking / novel
  technology application?
• ENGAGE the common interest parties to strengthen
  voice (lots of groups saying similar stuff but
  not talking to each other enough or communicating
  effectively with others need to get the message
  out there)
• OPPORTUNITY to get developers, investors,
  managers, technologists and both sides of
  politics involved

19
Suggestions cont.

• SEEK the common thread that links all the groups
  together having something that everyone has to
  deal with (eg plethora of small builders,
  planning permissions)
• See new buildings as a link to network planning
• Avoid confusion between multiple rating tools
• Labelling (car vs building purchase)
• Most councils no longer keep house buildings and
  plans?
• CLARIFY the issues (another roundtable?)
• managing peak energy demand, which may be
  different to managing the average
• Time issue?

20
Suggestions - cont.

• Crystallise the benefits
• identify existing economic drivers (eg capital
  operating costs, energy water use, greenhouse
  emissions etc)
• identify existing evolving stakeholder needs
  (eg security, health, electricity networks, rents
  etc)
• solve for transfer of value between developers,
  owners, occupiers other stakeholders to achieve
  desired outcomes
