Hello everyone, I am working on a data centre project, I have a query regarding the energy modelling approach for a data hall. Should the design temperature be considered as the average of the cold and hot aisle temperatures or if it is necessary to model spaces and consider the cold and hot aisle design temperatures separately, While as per ASHRAE recommended guidelines, the air temperature should be maintained between 18°Cand 27°C in the cold aisle (rack inlet) and between 30°C and 38°C in the hot aisle (rack outlet). Additionally, I would appreciate any recommendations on alternative approaches or best practices that can be adopted for temperature modelling and control in this context.

I suggest going through the OpenStudio-Standards LargeDataCenterLowITE module, which relies on the EnergyPlus ElectricEquipment:ITE:AirCooled class. I believe the solution is largely based on the methodology described here.

I'd argue that this is a good starting point for OpenStudio/EnergyPlus ...
