Hi, I am writing my thesis for a big organisation and am focussing on one location where they manufacture supplies. My assignment is ''How can X create a better energy performance of their buildings and their indoor processes in order to consolidate X sustainable commitment?''

I was thinking of using the Building Energy Modeling, but I do not need 3D models, only the outcome and graphs of how well it performs. However, I just stumbled upon the Building Performance Simulation.

What is the difference and what is best to use?
