The gross exhibition space is defined as the hall space and/or outdoor space, which comprises the net exhibition space made up of stands (omitting upper tiers) and ancillary areas used for traffic and services for the exhibition in question.
Service areas are defined as areas which pertain directly to a respective exhibition but which may not be used by exhibitors for their presentations.
Service areas include temporary catering areas within the halls; areas for public authorities, associations and institutions used to provide general services for exhibitors and/or visitors; demonstration areas such as arenas, stages, halls etc. insofar as they do not fulfil the requirements of a special show space.
All areas designated for regular office use, for meetings and conferences etc. are not part of the gross exhibition space. Nor are storage areas, catering areas featuring permanent installations or corresponding outdoor areas part of the gross exhibition space.
At farming exhibitions, outdoor demonstration areas are calculated without any extra percentage as part of the gross exhibition space.
