“…In Ref. [19], a hybrid model of a ground source HP using analytical and artificial neural network models to represent a ground source HPs long-term behaviour accurately is outlined. The HP model was compared to measured data and demonstrated to be accurate with a mean absolute error of less than 5%.…”

“…Puttige et al used measured data to develop simple and accurate models for GSHP systems, combining a hybrid analytical-ANN model for the borehole heat exchanger (BHE), an ANN model for the heat pumps, and an empirical model for system heat exchangers (Puttige et al, 2022). The BHE and the heat pump models achieved a mean absolute error (MAE) of less than 5%, while the heat exchanger model had an MAE of 18%.…”

This article introduces a modern thermal energy plant consisting of sewage heat pumps, a biogas boiler, thermal solar collectors, and grey water recycling. It further discusses advanced methods to achieve energy efficiency in the plant operation. The project is a collaboration between the industrial plant designer, the municipal plant owner, and the local academic institution. The article presents the framework for the collaboration. The overall target is to investigate how the experience and competence of the three partners can lead to improved operation using data-driven methods and optimization strategies. The industrial partner can closely follow up on its design and increase its knowledge of artificial intelligence and data-driven methods. The municipal partner is given a “free-of-charge” system review. New knowledge and reduced life cycle costs and emissions are possible outcomes. The academic partner gets access to a “living green laboratory,” a unique dataset, and the opportunity to validate developed models and optimization strategies. The plant represents the state-of-the-art for a medium scaled, local thermal energy production system in an existing building cluster. The design energy and emission targets are presented and compared to the operational results. Though the municipal partner can report good agreement between targets and results, an evaluation of the day-to-day operation identified practical examples of system conditions that Artificial Intelligence may improve. The article concludes with a description of plans for future work and a broader discussion of the impacts of introducing data-driven methods to real-life systems.

“…The interior temperature of the hangar was set at 18 o C. In order to meet the heating load of the hangar, it has been suggested to convert 600 bored piles into energy piles. Typically, the distance between the boreholes is taken as 5-7 m in the studies conducted for the vertical GSHPs [26,27]. According to the data in the project, the desired distance between the pile wells is 4 m or more, which is acceptable in terms of heat transfer in the soil.…”

In this study, the heating and cooling needs of an airplane hangar by integrating a heat pump system into bored piles were investigated. For this purpose, U-type pile heat exchangers were installed inside the piles. 600 bored piles were integrated with heat exchangers depending on the heating requirements of the hangar. Energy calculations were performed for a single pile, and the total amount of energy that could be extracted from the ground was determined. The main goal is to supply cooling and heating for the hangar throughout the year without the use of any additional conventional system. Thus, cost-analysis results for both the heat pump and traditional system using levelized cost method were presented. The study results showed that the annual operating cost (COM)PW, total operating cost (IOM)PW, equivalent annual operating cost (COM), and total annual cost (CT) for the present condition reduced by nearly 38.5%, 35%, 35%, and 34% against the conventional system, respectively. The simple payback period was calculated as 1.1 years. Finally, it was seen that using the energy piles can provide the heating and cooling requirements of the hangar throughout the year without any additional conventional system.
