DGNB criteria "Building life cycle assessment"


Our objective is to ensure a consistent life cycle approach to the planning of buildings in order to reduce emissions-related impacts on the environment and consumption of non-renewable resources to a minimum across all stages in the life of a building.


A life cycle approach to the building planning, using life cycle assessment, helps building commissioners and designers to make environmentally friendly decisions on the basis of comprehensive information. This enables the identification of solutions that are optimised, both in terms of various relevant environmental issues and in terms of various locations and times of environmental impacts. The application of a consistent method is useful for reporting relevant environmental indicators for a building, such as CO2 emissions or energy demand throughout the entire life cycle.
