Nachfolgend werden Einzelaspekte des nachhaltigen Bauens aus energetischer, ökonomischer, konstruktiver und baupraktischer Sicht kommentiert.

Aging with dignity - energetic efficiency and sustainability in housing construction.
Individuals need to be treated individually - this applies both to humans when it comes to health problems e.g. and to building. Each case for itself demands the definition of the valid criteria for sustainability, even though this may be difficult. For example: Is it economically sensible to establish property with a high level of energetic efficiency up to energetic autonomy at a location, which is urbanistic unattractive, has the outlook of shrinking numbers of inhabitants and therefore no expected further utilization in future? In this case it will be quite difficult to position the object at the market, even though it has its excellent energetic standard. However different will be the situation of an object in an attractive neighbourhood: High economic potential always allows the merchandise of a building, regardless in what energetic shape it comes.
