<p class="MsoNormal"><span lang="EN-AU">I have modelled a residential building with different building components (including different thermal masses) using Trnsys 3d, Type 56 . The simulation results show no thermal lag between hourly inside air temperature
of each zone even if, the heavy materials are used. It is weird as it seems that Trnsys does not take into account the thermal mass of walls, floors and etc.
