Various alternative verification methods have been developed for Europe in the last 10 years. These enable verification of numerous criteria based on European standards (instead of by comparison with US-ASHRAE standards). The assessment of energy efficiency is excluded from this, as calculations based on the German Energy Savings Directive (EnEV) are justifiably not accepted by the USGBC as an instrument for energy demand forecasting due to the use of standard profiles.
The USGBC offers owners, developers of comparable properties (comparable in terms of their use, building type and standards) the method of a group certification (volume certification). First, a basic certificate is obtained here for a prototype of a portfolio; for the subsequent certifications, only the deviations from this initial assessment have to be documented, making the process far simpler, see also usgbc.org/tools/leed-certification/volume.
The certification process is operationally managed by the Green Business Certification Inc. (GBCI) on behalf of the USGBC. The central contact for Europe is GBCI Europe mit Sitz in München zentraler Ansprechpartner.
