+ Insulation of buildings?

So what is about:

+ Use of solar energy ?

+ Use of biomass energy ?

+ Use of timber in buildings ?

+ Use of wind energy ?

7

+ Insulation of existing buildings?

Design buildings as passive houses from the beginning?

The challenge?

Improvement of energy efficiency and climateprotection as the motor of development !

But: A pure passive house standard is not sufficient!

Complete developments of energy self-sufficientareas is necessary !

In addition a new systematic of buildinginstallation and supply of energy is necessary !

First examples are under development, e.g. Pfaffenhofen

Rember: If you transfer people to the countrysideyou also have to provide public transport !

Otherwise it will be an energy trap!

The role of timber?

• factory forest – the welfare factory• low energy material• renewable• very well fitting properties

and

a carbon storage!

The world leading sustainableconstruction material!
