PUE/WUE Studies
Evaluate the energy and water performance of a data centre and quantify the impact of architectural and regulatory choices.
PUE and WUE respectively characterise the energy efficiency and water consumption of a data centre. However, their value strongly depends on the architecture of the cooling systems, climatic conditions, and regulatory strategies. Therefore, a value calculated at a given operating point does not always suffice to represent the actual performance of the installation over a year.
SIL3X develops models representing the main equipment and systems of a data centre: cooling production, heat exchangers, cooling systems, pumps, fans, and controls. These models can be built from the characteristics of an existing installation or used from the sizing phase to compare different architectures.
By integrating representative climatic data of the site and the operating profiles of the equipment, we simulate the behaviour of the system over a complete year. The electrical and water consumption are then calculated taking into account external conditions, the loads of the data centre, and regulatory strategies, in order to estimate the annual PUE and WUE.
This approach also allows for the evaluation of different evolution scenarios: modification of setpoint temperatures, change of cooling strategy, evolution of regulations or modification of architecture. Potential gains can thus be quantified before their implementation and compared to the performance measured on an existing installation.
