Both Green Infrastructure and Ground Source Heat Exchangers provide opportunities to significantly improvethe resilience and sustainability of our built environment. This work explores the thermo-hydrological responseof a vegetated Sustainable Drainage System under physically simulated heat injection conditions using a soilcolumn of 1800 mm diameter and 950 mm height in a heavily-instrumented lysimeter. A range of fieldtesting scenarios (thermal load and cycling) were applied under natural, external ambient conditions. Soiltemperature during heat injection was also simulated numerically by solving a transient heat conductionequation with a finite difference modelling scheme. The developed model was validated using measurementsfrom the lysimeter setup which then enabled numerical experiments into the effects of varying hydrologicalregimes to be performed. Results of the field testing showed that heat injection propagates a temperaturechange only at deeper layers, while the temperature of shallow layers are still governed by the atmosphericconditions.
