Sustainability of construction works - Assessment of environmental performance of buildings - Calculation methods CEN/TC 350 /WG1 N015rev1

Scope

This standard is applicable to all buildings and provides a methodology for the assessment of the environmental performances of a building. This assessment is mainly based on the result of the Life Cycle Assessment (LCA) for each of the environmental aspects over the life cycle of the building in the framework of the integrated performance of buildings. The standard describes the calculation methods for environmental core indicators defined in the framework standard according to the type of the building and various stages of the building life cycle. The standard describes the system boundaries for LCA and the European rules for LCA outcome for each aspects in order to allow for aggregation. This standard describes the assessment of data quality for LCA-data and the effect of data-quality on the results of the LCA for buildings.
