The problem we all have in common

In heating our houses we are far not so sensitive
to energy prices.

The step towards energy security
The cheapest energy is the energy not used

Making EU the most energy efficient economy in
the world !

Energy use in Europe
40 of Europe's energy is used in buildings The
buildings have an enormous energy-saving
potential Insulation is by far the most
important measure to reduce the energy use in
buildings

Passive House means independency in energy
The way to autonomy in energy.

Isover Multi-Comfort-House fits for all climatic
zones (with modifications)
25
The high energy consumption is part of the
planning and culture
To improve thermal comfort energy consumption
turns excessive !

Isover Multi-Comfort-House concept is adopted
internationally

Running activities

• Cooperation of Insulation Branch with
  IG-PassivHaus in Austria and Germany
  (Associations to support the development of
  passive houses).
• Concourse  Passive House  (renovation) for
  architects in Isover Western European Region in
  2005-2006 (open for every country !!!).
• Concourse  Passive House  for students in
  Eastern Europe (Serbia, Romaine, Bulgaria,
  Croatia, Macedonia) Awards has been given on
  1st of June 2005 in Sofia.

Isover Comfort Energy Efficient House is a bargain

• Short payback period for additional construction
  costs of about 5-8.
• Interest rates for financing are lower than the
  annual increase of energy costs.
• The price for fuel reaches nearly daily a new
  record.
• Passive Houses have annual heating costs of about
  1,- Euro/m² and year.
