Short summary
In cities, large thermal plumes often limit groundwater-based heating and cooling. Unidirectional ATES reverses the well arrangement so heat and cold are transported by natural groundwater flow and reused seasonally. At Graz South Hospital, modeling shows efficient energy recovery, strongly reduced off-site impacts, and high potential for climate-friendly energy supply in space-constrained urban areas.
