Troubleshooting and HVAC-Simulation

In some tenant areas had appeared climatic uncomfortable ambient air conditions. Winfried Haas has been assigned for troubleshooting. He has analysed the operation conditions and the function of the cooling production plants as well as of the major air handling units. He has undertaken some energy modelling of the air conditioning process using state-of-the-art computer simulation tools in order to solve the issues.
