Data centre space cooling systems consume a lot of energy and will increase over the years. Therefore, it is necessary to propose new refrigeration strategies. Radiative cooling (RC) production is a renewable alternative solution with a promising future. In this work, the energy modelling of the air conditioning system of a data centre coupled to a RC emitter is carried out to explore the benefits of this technology. The system consists of a water chiller connected to a cooling coil through which air is circulated for distribution in the data centre room. The simulations were carried out for a typical summer week in Barcelona. The RC production was carried out during the night, and this energy was used during the day and was implemented directly in the energy balance of the data centre room, considering emission surfaces of 80 and 60% of the total building roof, reducing the water chiller energy consumption by 13 and 10% respectively. In the transient behaviour of the temperature in the data centre room, when the RC was used to reduce the peak cooling load, a reduction of the temperatures was observed approaching to the design setpoint, therefore, the Information Technology (IT) equipment was not affected.
