To investigate the hygrothermal conditions in subterranean car parks a twodimensional simulation procedure has been used, based on coupling the transient heat transfer programme HEAT with the dynamic thermal building simulation program TRNSYS. The likelihood of condensation and the rate of water deposition on surfaces were calculated with a new moisture model KOND. To estimate the consequence of moisture adsorption in materials in the hygroscopic range below saturation, the TRNSYS moisture capacitance model (buffer storage model) was used. A parametric study of the internal temperatures and the annual hours of condensation risk in underground car parks were conducted using German and UK climate data. The simulations indicate the relative risk of condensation occurring for different earth conditions, levels of insulation and air change rates, in spaces covered by earth and spaces covered by a heated building. It is shown that increased ventilation rates in summer can reduce condensation risk in underground car parks below heated buildings.
