Conceptual Energy Analysis (CEA) is a high-level analysis tool to deliver preliminary feedback and understanding of how the model created responds to site and climatic environment. This process can and should be used multiple times at different stages during the design process. It works for different scales but generates a set of data most relevant to comparing multiple design options of the same building. It will become important to spend some time thinking about the resulting data from the analysis as Vasari cannot speak to the implications of the new information.
