Schrannenhalle Munich, the existing HVAC installation \u2013 in particular the hybrid dry coolers \u2013 had to be temporarily dismantled. Ingenieurb\u00fcro Ingo Geib GmbH (IBIG) was responsible for the planning, coordination and technical supervision of the measure \u2013 from dismantling and setting up a temporary cooling supply on the ground and site management of the new installation on the roof. The operation of the 1.0 MW water cooled chiller in the basement could be maintained throughout the construction phase, apart from a short, technically unavoidable interruption.
