Despite their high-efficiency benefits in heating and cooling applications in buildings, ground-source pumps are challenged by their high installation costs (Mattinen et al., 2014). Mustafa Omer (2008) also observes that the technology has received significant attention due to its efficiency and as a result, is well established in North America and other parts of Europe. Other researchers, such as Shen and Lukes (2015), further investigated the performance of the GHSPs in future climatic conditions (2040-2069) using the estimated future hourly weather data in US cities. Findings reported showed that with the rise in global warming, the efficiency of GHSPs is anticipated to reduce in residential areas due to the steady increase in energy consumption in the ground loop. Choi et al. (2018) have also cautioned that the operation of GHSPs under load balance conditions is likely to result in performance degradation and thermal intrusion problems, particularly in high building densities where they are close to one another. As such, the researchers argue that there is a need to consider conditions of subsurface thermal boundaries in the long-term simulation of GHSPs.
