Why do you do an energy model of your building architecture? It depends on the project, but sometimes the energy model is used to tune the design, sometimes it's used for LEED, sometimes it's used to justify energy efficiency incentives.
Modeling the mechanical systems can also serve all these purposes. You can compare systems, choose the best equipment based on efficiency and performance curves, evaluate controls strategies, etc.
