What ist green? Benchmarking the environmental performance of sustainable buildings
In Germany, the 'Certification for Sustainable Construction' currently receives tremendous attention throughout the building industry and from the general public. Launched with the claim to demand for meeting performance indicator benchmarks, it uses Life Cycle Assessment (LCA, as defined in ISO 14040/14044) to quantify the environmental performance of a building's life cycle. Along with Life Cycle Costing, LCA is one of the two single most relevant assessment methods within the system, which currently has around 50 criteria in the version for new construction of office buildings. Due to its nature of being applicable to any product, process or service, LCA is standardized to allow for extensive adaptations to the scope of the assessment. The German Sustainable Building Council (DGNB) specified the application of LCA for the certification procedure in detail. This includes the life cycle stages and system boundaries to be considered, the environmental impact categories to be assessed (such as Global Warming Potential) or the background data to be utilized. Moreover, LCA indicator benchmarks are set by the DGNB for buildings to be met over the entire life cycle. These benchmarks use a fixed value for the building's constructional stages including building materials, maintenance and end-of-life, and a variable value for the energy demand, based on the German implementation of the Energy Performance of Buildings Directive (EPBD).
