Vicious Circle of Blame
Owners/End-Users Wed like to own sustainable
houses but there are very few available.
Designer/Constructor We can built or retrofit
buildings in a sustainable way but developers
don't ask for it.
Investor We would invest in sustainable buildings
but there's no demand for them.
Developer Wed ask for sustainable buildings but
the investors don't ask for them.

  disability upgrades)
• Managing properties in beneficial ways (e.g.,
  fair labour practices for service workers or
  using environmentally friendly cleaning products)

Theory of Behaviour
Theory of Organisation
Theory of Integration
The individual person with his behaviour and
preferences is in the main focus of the theory.
He always strives for maximizing his profits and
therefore presents the initial component for all
kinds of mathematical models. gt "Homo
oeconomicus"
Defects, that occur in the system, are adjusted
by rules. In order to find a balance between the
actors, institutions are installed to create and
control penalties, conditions and incentives,
e.g. government, jurisdiction.
Still, the actors are in the centre of the
theory. But to guarantee satisfaction of all
human needs, decisions and activity have to
respect and comply with limitations of
resources. This is to take into account for the
time being AND future generations.
