ABSTRACT
ABSTRACT The description, assessment and targeted influencing of the life cycle-related environmental performance of buildings has now become an important additional design task. In addition to indicators used to quantify the use of resources and undesirable effects on the global and local environment, as well as appropriate rules, data bases and calculation tools, assessment benchmarks are also needed. For the development, application and interpretation of benchmarks there are no generally accepted principles so far. The paper therefore presents proposals for methods and approaches that are currently incorporated in the work of IEA EBC Annex 72 and ISO TC 59 SC 17 WG2. Possibilities for the development of limit, reference and target values, the handling of political goals for climate neutrality and the transparent description of benchmarks are presented. For the declaration of benchmarks, a data format is proposed. Finally, general rules for the preparation, application and interpretation of benchmarks are discussed.
