The building material classification is orientated to the information needs of the actors from various levels of action and subject areas. It is based on a life-cycle approach and offers a continual view of the material flows taking place – from raw materials (extraction from the environment) to the building materials themselves to the waste categories (source for secondary materials). In the course of this, emissions referenced to life-cycles are considered.
The building material system differentiates 46 building material categories, under which approx. 130 individual building materials are subsumed. The 46 building material categories are grouped into ten categories (i.e. seven categories for the diagram representations).
Starting from the building materials:
• raw materials are derived by means of formulas (“recipes”). The classification of the raw material categories is based on the standard classifications of national and regional raw material planning.
• waste categories that arise during demolition are defined with the aid of the waste classification list (AVV)
• material-induced emissions (grey emissions) are ascertained by linking with environmental impact data from Ökobaudat.
