Abstract: Sustainable Drainage Systems (SuDS) have been established as the main alternative for sustainable rainwater management. However, SuDS have a high multipurpose potential for geothermal utilization, as pointed out by previous research. This work aims to study the thermal behavior of a green swale in the field to evaluate its potential performance in combination with a shallow geothermal system. To this end, a swale was installed in the field and designed to optimize its thermal performance. Temperature and heat flow data inside the swale, as well as ambient temperature values and rainfall, were collected. Data collected over several weeks indicated that the interior of the swale has a more stable thermal performance, which makes it suitable for installing heat exchangers in the ground.
