Equinix’s subcontractors Unica and RHDHV asked Actiflow to perform an extensive analysis of the flow around the building. Therefore we made a detailed computational model including the surrounding buildings, all cooling devices on the roofs of AM3 and AM4, all exhausts and intakes and details like porous screens, lamellas and falls roofs. We then used this model to calculate the flow of air and the distribution of temperature and water vapour in several scenarios. These scenarios vary in operational mode (normal, maintenance, emergency) and weather conditions (high or low temperature, wind speed and direction).
The study provided both the subcontractors and Equinix with extensive insights in what could happen under a variety of circumstances. It was used to complete the risk-assessment, to optimize the design and to determine the energy use of the data centre. The insight the CFD-study provided made it possible that the related engineering challenges were solved to an optimum.
