It has been proposed in China that the country should reach a “carbon peak” by 2030 and be “carbon neutral” by 2060. In the context of energy conservation and emission reduction, the country’s energy structure needs to be transformed to improve the technology level and more widespread consumption of renewable energy. The global renewable energy utilization situation is first analyzed in this study from the perspective of renewable energy and the buildings using it, highlighting the importance of the application of renewable energy in buildings. Secondly, from the perspective of solar energy utilization technology, ground source heat pump technology, and systems for managing energy use in buildings, the progressiveness of renewable energy applications in buildings is analyzed. The application of these technologies in buildings is demonstrated from various angles. Thirdly, the development prospect of buildings using renewable energy is discussed from the perspective of the promotion of renewable energy-powered buildings and green construction. The development prospects of buildings using renewable energy are discussed from the economic benefits of green finance, the promotion and social support of renewable energy, and the environmental benefits of green buildings. Finally, based on studies in the United States, the United Kingdom, Russia, and China, the international energy policy and development direction, as well as the evaluation criteria of green buildings, are discussed, along with an assessment system for green buildings that is complementary to the strategic agreement.

“…Looking at the period from 1995 to 2020, there has been a remarkable increase in the adoption of ground source heat pumps, indicating a growing recognition of their benefits and efficiency [8]. According to the most recent data, the leading countries in terms of installed GSHP capacity include China, the United States, Sweden, Germany, and Finland, with capacities of 26450, 20230, 6680, 4400, and 2300 MWt, respectively [9]. This global trend underscores the growing appreciation of GSHP systems as a sustainable and efficient solution in the development of smart cities, and underscores the critical role of accurately assessing the potential of geothermal energy in urban planning and construction.…”

This study examines the optimization of ground source heat pump (GSHP) systems and energy piles for sustainable urban development, with a focus on Southeast Asia. GSHPs, which utilize geothermal energy for indoor HVAC needs, offer a sustainable alternative to traditional systems by utilizing consistent subsurface temperatures for heating and cooling. The study highlights the importance of understanding thermal movement within the soil, especially in soft marine clays prevalent in Southeast Asia, to improve GSHP system efficiency. Using a one-dimensional finite-difference model, the study examines the effects of soil thermal conductivity and density on system performance. The results show that GSHP systems, especially when integrated with energy piles, significantly reduce electricity consumption and greenhouse gas emissions, underscoring their potential to mitigate the urban heat island effect in densely populated areas. Despite challenges posed by the region's hot and humid climate, which could affect long-term effectiveness, the study highlights the need for further study, including field experiments and advanced modeling techniques, to optimize GSHP configurations and fully exploit geothermal energy in urban environments. The study's insights into soil thermal dynamics and system design optimization contribute to the advancement of sustainable urban infrastructure development.

“…Such an energy production technology is environmentally friendly because, compared to other heating options, no gas/water emissions or wastes are generated during the heating process, and the aquifer budget is not affected by the reinjection of groundwater. Several studies have been conducted worldwide to investigate the regional and national potential of groundwater heat exploitation [12][13][14][15]. However, there are several potential problems associated with the installation of open-loop doublets of extraction and reinjection wells.…”

This study presents a simulation of potential changes in groundwater in three wells within a Quaternary gravel aquifer in the city of Ljubljana when groundwater cooled by about 4 °C is reinjected into it. The research focuses on the mass transport of calcite in the vicinity of boreholes. According to our results, the impact of the changes in the geochemical composition of the water is relatively small (around 1%). Although the waters are approximately in equilibrium, calcite may be dissolved and sometimes precipitated within the aquifer when cooled water is reinjected into it. The amounts of precipitated calcite always decrease with decreasing temperatures of the reinjected water, which can lead to calcite dissolution if the temperature difference is large enough and the water is only slightly oversaturated. This novel finding is significant since previously published studies have mostly focused on understanding the scaling (precipitation) of calcite and not its dissolution. The mass transfer of calcite is relatively low, but in a scenario of long-term pumping for several years, such low values could lead to a dissolved or precipitated mass of several hundreds of kilograms of calcite per year (at a pumping rate of 46 L/s).
