Old and deep subway lines suffer from overheating problems, particularly during summer, which is detrimental for passenger comfort and health. Geothermal systems could serve as one of the potential green energy efficient cooling solutions, compared to energy intensive conventional cooling. The waste heat of the subway tunnel can be harnessed, to provide heating to residential and commercial blocks above the tunnels. The climate of a representative section of the London Underground�s (LU) Central Line (CL) is modeled using a 1D Modelica based software called IDA Tunnel. A 3D Comsol model that includes geothermal vertical boreholes on the tunnel sides is developed to asses their potential in cooling the LU tunnels and platforms. The IDA and Comsol models are co- simulated through exchanging boundary outer tunnel wall temperature information inorder to model the transient interactions between the boreholes and the tunnel and platform environment.
