Since this is a data room, I'm going to assume that by "free cooling" you mean it has an economizer, and not that it uses natural ventilation. You could start with an HVACTemplate- maybe a Unitary system depending on what you are looking for. If you have no DX cooling, you can specify the cooling coil type as "none", but still specify economizer operation. Reference the HVACTemplate-5ZoneUnitarySystemin the "ExampleFiles" folder of your EnergyPlus installation.

Or you could look at the "2ZoneDataCenterHVAC_wEconomizer" example file.
