Since version 6.3x several rooms of the building, including open spaces, could be assigned to a common functional area. Up to version 7.3 in addition to the representational function (single hatching) it had, however, no further effect. The building structure was fixed and classified by the units “area”, “floor” and “room”. Creating a division in units was limited and only possible by creating multiple areas on a single floor. With version 8, the first relevant connections for calculations have been made between the zone and other building parts (i.e. area, floor and room). Each zone defines a separate functional area (e.g. a single apartment), which, as is common for example in a high-rise building, may extend over several floors. For the calculation of e.g. controlled ventilation and potable water systems only components assigned to a functional area (i.e. zone) will be considered independently of the others. |
