This article presents a simulation study comparing the thermal interior comfort performance, the energy consumption and the efficiency of (i) nighttime ventilation concepts considering varying air change rates, (ii) three thermo-active building systems (TABS) and (iii) ceiling mounted radiant cooling panels in a low energy office building for a chosen climate of the Test Reference Year (TRY) weather database as well as for the hot summer 2003 in South-West Germany. The investigation comprises the ambient air and the ground as low-exergy heat sinks. The simulation study bases on a building and plant model within the simulation environment ESP-r which is validated by means of measurements derived from long-term monitoring in a low energy office building.
