SIA/KBOB

Life cycle and energy assessments according to SIA (SIA 380 and SIA 2040 / SIA 2032) are based on the data source Ökobilanzdaten im Baubereich (current version: 2009-1:2022), which is jointly published by KBOB (Vereinigung der öffentlichen Bauherren der Schweiz), the ecobau association and IPB (Interessensgemeinschaft privater professioneller Bauherren). The emission factors consider the entire life cycle and therefore include, in addition to the direct emissions from energy use, the emissions from upstream and downstream processes. A breakdown of direct emissions and LCA share of the emission factors is missing which is why the SIA/KBOB framework cannot be used for reporting frameworks that are based on the GHG Protocol (such as AMAS, REIDA, PCAF, CRREM, etc.).
