• Why more energy efficiency ?
• - energy shortage and raising prices
• - due to increased emissions of CO2 and
  greenhouse gases climate change
• - global increase of energy consumtion by appr.
  70 100 until 2050
• - over a half of the world population enters
  just now into the energy market
• - Aim of EU Decrease of the greenhouse-emissions
  by 80-95 until 2050
• CO2 CO2 CO2 CO2 CO2 CO2 O2

• Similarities between Slovenia and Middle
  Germany
• history-charged towns 20.000 300.000
  inhabitants charming downtown areas culture
• old buildings high energy consumption
• similar laws in terms of Energy Efficiency and
  Renewable Energy
• Energy law - Energetski zakon, Energy pass -
  Energetska izkaznica, feed-in-compensation for
  renewable power
• Positive human influences

• Old Buildings
• Possibilities for energetic redevelopment
• Architectural
• thermal insulation (outside or inside, roof,
  cellar,..)
• Windows with better insulation
• intelligent solar protection
• Building materials with storage capacity
• Technical
• Modern heating system (Heat pump, power-heat
  coupling, Solar-Plants, better regulation)
• Modern cooling systems (Solar cooling, cooling
  with earth-source, adiabatic cooling)
• Low temperature heating and cooling
• Decentralized electricity generation
  (photovoltaics, small wind turbines, power-heat
  coupling)
• Energy-saving electrical equipment and
  illumination
