Thermal modelling

Imagine a situation where you need to analyse an apartment in a multi-storey tower block or a unit in a large row of terrace houses. For absolute accuracy you would need to model the whole building or row in order to fully account for heat flow paths between floors or party walls. However, in many cases it is possible to assume that temperature differences between adjacent apartments/units will be insignificant and that the major influences on each zone’s thermal environment will be its internal conditions and those areas of the building fabric exposed to the outside. If this assumption is reasonable in your particular case, then you may only need to model the actual apartment/unit you are interested in.
