What can we achieve through life cycle assessments?
The DGNB has made it its primary goal to plan, operate and use the built environment of the present day for the benefit of all, and in such a way that the generations that follow us can fully utilise their own potential and not be constrained in their opportunities by the decisions that we make today. This goal is inevitably linked to planning districts, buildings and interior spaces in a way that is logically oriented to their entire life cycle, reducing both the consumption of finite resources and environmentally critical air, water and soil pollution to a minimum across all phases of a building's life.
The appropriate tool for this purpose is the method of life cycle assessment (LCA ).
Aim of these guidelines
These guidelines aim to promote the increased use of life cycle assessments in the planning process, by demonstrating the relevance and potential of this tool. Designers and building contractors are additionally provided with arguments for employing these methods as an optimisation tool as early as possible in the planning and implementation process, and the sustainability effects that can be achieved as a result of this are emphasised. Furthermore, the reader is presented with examples of how the results of life cycle assessments are communicated and can serve as supporting arguments for making more environmentally sensible decisions in the course of the planning process.
