Item Holistické řízení datacenter: Metodika pro uvedení do provozu víceoborového řízení datacenter s použitím simulace budov(2019) Zavřel, Vojtěch; Torrens-Galdiz, J. Ignacio; Hensen, Jan L.M.; Tecnalia Research & InnovationThe world data center energy consumption has been growing rapidly and currently is estimated at 1,7–2,2% of the world-wide electricity consumption. Achieving sustainability in this sector calls for development new energy efficient strategies and measures. Current research deals with development of holistic operation i.e. operation, where all essential processes such as data processing, cooling and power delivery and supply (including renewable energy sources) are optimized a coordinated. Testing of modern operational strategies, which is necessary for development and commissioning, is not possible during the regular operation due to the risk of limitation of the services or outage of the data center operation. Any outage of the data center is related with financial and reputation losses. Therefore, the testing is extremely limited. Alternatively, building energy simulation may offer “safe” testing environment for advanced control algorithms and accelerate their implementation in practice. This paper describes a novel workflow for testing of modern control algorithm and new application of building energy simulation of data center.Item Simulation-based assessment of data center waste heat utilization using aquifer thermal energy storage of a university campus(2020-08-01) Dvorak, Vojtech; Zavrel, Vojtech; Torrens Galdiz, J. I.; Hensen, Jan L. M.; Tecnalia Research & InnovationThe global energy consumption of data centers (DCs) has experienced exponential growth over the last decade, that is expected to continue in the near future. Reasonable utilization of DC waste heat, which is dissipated during the computational process, can potentially be an effective solution to mitigate the environmental impact. However, the practical implementation of waste heat utilization in the DC environment is a very challenging task. The possible benefits of waste heat utilization are uncertain and difficult to quantify with the methods that are common in practice. This paper introduces a feasibility study in which dynamic simulation tools were used to predict the energy performance of a university campus resulting from the integration of a proposed DC system with an existing aquifer thermal energy storage (ATES). The presented study utilizes building energy simulation (BES) to evaluate uncertainty of the waste heat potential associated to various thermal management strategies of the proposed DC. Further in the feasibility study, the carbon footprint of the integrated approach is assessed for both the current and future situation based on measured data from the existing university campus and its district ATES system.
