Water use is limited to sanitary facilities, the pantries, cleaning purposes and catering (drinking water). Fresh water is obtained directly from the supplier Hamburg Wasser. Since 2017: no values for CCH due to revitalization. The values are dependent on the weather, years when events are strong or weak, and energy-related conversions. 2020: Corona-related effects (hardly any event business).

  The values are dependent on years in which events are strong or weak. Corona-related deviations are possible. Some values may be due to construction work or retrofitting, such as the switch to LED lighting in the Lagerstrasse parking garage or the renovation of the parking garage West ceiling at Halls A3/A4. The waste disposal method is determined by the disposal company and recycled in a standard and professional manner. Waste separation is a given.
