Many elements of an MEP design are relatively straightforward. There is usually a right way to do things and a wrong way. Often, these decisions are clearly based on codes, or at very least on convention. Controls and BAS, however, are rarely this straightforward, and in many cases there is a good, better, and best way to control a system. Understanding these options, the costs and benefits, and how to achieve them on your next project is not well understood by owners and their design teams.
