What is the vegetated assembly being used for? What could it be used for? Why is it used that way? Is it the only way it could be used? These are general questions into aesthetic and performative functions of these assemblies.

Location: Interior or the Exterior of the building or other structure can lend itself to a type of use. Usage: interior uses are often more for decoration, as the main performance-based functions of a vegetated system are found in stormwater retention and shading of the building. Maintenance: Decorative plants often need more pruning and
watering than performance species. this is species based.

These criteria are not meant to be a deciding factor. instead understanding the purpose of the vegetated wall can help to inform design decisions. For example: a decorative wall can be more varied in its placement and plant species. these walls are not necessarily meant to be low maintenance or be stormwater catchment. This can make the wall a more about a series of layers. However the vegetated wall needs to be considered as a part of an integrated building envelope. if the wall is considered and add-on if the money is there, then the wall will not be as successful.

This is the difference between decoration and decorative. Decoration is an additive element after the fact. Decorative is in its intent to be integral to the design, but is not necessarily structural.

In architecture this is considered as ornament. this concept of more or less ornament is what contributed to entire movements of architecture. This can lead into what is called tectonics. These tectonics are often clear and ordered, being consistent in idea, and organization. In this sense, what could be the architectonics of the vegetated wall?
