For each space, the walls and slabs that limit it are defined. When one of these elements is an interior partition, i.e., a partition or a floor between floors, the space that lies on the other sidemust be defined. Until now, users could choose an adjacent room amongst those defined in the project or leave this field empty, which implied that the partition is adiabatic, that is, no heat is lost or gained through it.
In the 2019.f version, the definition of the existing options is explicitly indicated in "Adjacentspace" and the new option "Unknown space" has been added. This option allows users to more adequately define the partitions that are next to spaces of other buildings, whose use is unknown and have not been defined in the project. For design purposes, this unknown space will have the outside temperature.
