Another example might be a "shoebox" model. In early stages of the development of a new construction building (schematic design stage), it is often used. The design has just started, so there's a lot of uncertainty and things will change often and a lot. It is impossible (and doesn't make sense) to create a detailed model. Yet there
You might create such a model by inputting its general shape and using a perimeter/core layout (5 zones per floor, all of "Office" type for example), use ribbon windows to match a window to wall ratio, and use fully autosized systems. It will then be used to determine high-level orientations for the design, such as options for the massing of the building, how much window to wall ratio you want, and the general HVAC strategy to be employed (for eg you might want to see the high level difference between using a chiller + cooling tower versus a VRF, etc).
Later on, when the design is more narrowly defined and things aren't expected to change that much, you will want to refine your model to more closely match reality. You'll draw the windows in their actual location, zone the building like it will be in real life (open office, closed offices, mechanical rooms, corridors, etc), and input the HVAC systems per the MEP's design (use the actual design values, etc).

Another example might be a "shoebox" model. In early stages of the development of a new construction building (schematic design stage), it is often used. The design has just started, so there's a lot of uncertainty and things will change often and a lot. It is impossible (and doesn't wouldn't make sense) sense anyway) to create a detailed model. Yet there are questions for which simulation can and should be used.
