Ökologische und ökonomische Gebäudebewertung für ein Einfamilienhaus in Varianten

Ecological and economic building assessment on the basis of an example single family house.

The present work deals with ecological and economic aspects of construction, maintenance and demolition buildings during a lifetime of 100 years. Therefore a real single family home was planned and analyzed for two different types: solid construction and light weight construction.
Nowadays the global warming potential is an important factor for the ecological evaluation of a structure. For comparison, various environmental indicators are discussed, including globalwarming potential, primary energy, water footprint, secondary fuels as well as abiotic resource depletion potential, ozone depletion potential and acidification potential.
In addition the finances play an important role in the construction of a house. Construction material in solid construction mainly consists of masonry and reinforced concrete while wood and insulation are primary materials in a lightweight structure. An evaluation and comparison is given in the present work.
The comparative analysis indicates an environmental benefit for lightweight construction, and lower costs in the production and maintenance for the massive construction. The presentation of the results and the choice unit can generate advantages or disadvantages for particular construction systems.
