A data center system includes a multi-floor housing having a first floor and a second floor housings which house a number of electronic racks of information technology (IT) components operating therein. The system includes a first set of indirect evaporative cooling units (IDECs) coupled to a first portion of the multi-floor housing through a first side of the multi-floor housing to direct exterior air through heat exchangers of corresponding IDECs to cool a first portion of interior air which cools a first set of the electronic racks. The system includes a second set of IDECs coupled to a second portion of the multi-floor housing through a second side of the multi-floor housing to direct exterior air through heat exchangers of corresponding IDECs to cool a second portion of interior air which cools a second set of the electronic racks. The system includes various DEC couplings/layouts and air flow management.
