	The geometry of the building is now complete. The next necessary (and highly important) step is to generate appropriate [[Plus 2.X:Zones\|zones]] for the building and to assign them to the respective components. This is important for our building as there are two different ways of utilization in our building; one part of it is used as living space, the other as fitness studio. Therefore the upcoming loads and requirements concerning heating, cooling, ventilation and humidification etc. '''vary greatly'''. This makes it necessary to distinguish between the two different sections in order to get reasonable calculation results. This is done by creating two different [[Plus 2.X:Heated Zones\|heated zones]]. The task of assigning the right zones to components is quite complex as a lot of tools and functions of ~~WUFI~~ can (or must) be used to succeed. <br>		The geometry of the building is now complete.
