PT infrastructure

• Apartment level
• Every apartment has a computer taking care of all
  input and output.
• Using technology like blue tooth all electronic
  equipment and measurement devices can communicate
  together and to the computer.
• Via PDA like devices the computer communicates
  with the user.
• Building level
• The main computer receives all required
  information and redistributes this, processed
  into useful information, to the apartments.
• The manager that operates the building and its
  site receives all necessary information on the
  computer.

Opportunities

• Energy consumption
• Electricity Increased efficiency / no more
  Standby / Sensible use
• Gas Sensible use of heating /
  Reduction of warm water usage
• Embodied energy waste
• Recycling Glass and paper can be recycled, make
  it easy for the people!
• Food Dont grow a cow that you are not
  going to eat!
• Wasting Use a normal glass instead of single
  use cups!
• Water consumption
• Shower Five minutes is enough!
• Domestic appliances Load the washing machine
  economically!

Dryer x Use because it is easy
Computer x It is on when it is not used
Household appliances x It is on when it is not used

Effects

• Goals
• Education towards energy use
• Create awareness of the energy quantity (KW/h)
  needed for each
• appliance.
• Persuasion based on freedom of choice.
• PT tool as a reminder
• Reward or punishment in function of your behavior

• Practical effects
• Each household appliance should have an
  interface of information/persuasion, so that
  one can be aware of his energy use/cost.
• Central computer and satelites software with
  persuasive reminder forms that can be disable or
  enable by its users or in bad behavior cases by
  manager.

  your freedom?
  
• How far punishment for a bad behavior can go?
• Till what point PT tool can offend you?

• Towards society
• Who can have access to your PT tool data?
• Is everyone able to see your energy use?
• Is it possible to catalogue individual energy
  consumption?
• Is it ethic to invest in this technology when
  there are people dying with hungry?
