Investigating the thermal performance of energy soldier pile walls

Nikolas Makasis et al.

Summary: Energy geo-structures are a promising application of shallow geothermal energy technologies. This study investigates the thermal performance of energy soldier pile walls and factors affecting this performance using advanced numerical modelling approaches. The results show that the depth and spacing of soldier piles have an impact on thermal performance, with higher values being desirable. Reducing the number of soldier piles may lead to a decrease in thermal performance, but the cost savings could make it acceptable. The choice of pipe configuration also affects thermal performance.

Thermal design of energy piles for a hotel building in subtropical climate: a case study in Sao Paulo, Brazil

Leticia Menezes Santos Sa et al.

Summary: The use of shallow geothermal energy through energy piles for the air-conditioning of buildings is increasing worldwide, but it is still not utilized in hot regions like Brazil. This study evaluates the use of a ground-source heat pump system with energy piles for efficient utilization of geothermal energy in Sao Paulo. The results suggest that ground heat extraction should be considered in air cooling-dominated scenarios.

Sensitivity analysis of a vertical geothermal heat pump system in a hot dry climate

Faisal Alshehri et al.

Summary: Ground source heat pumps (GSHPs) are efficient air conditioning systems that can help achieve sustainability goals by reducing electricity consumption and carbon emissions. The design of GSHP systems in hot, arid regions like Riyadh, Saudi Arabia, must consider soil characteristics and climatic conditions, with key design parameters including thermal conductivity, soil temperature, building load, and fluid flowrate. Optimal system performance in such regions can be achieved by adjusting the water temperature entering the heat pump.
