In this lesson we're going to cover modeling optimum start. We're going to focus on modeling optimum start for LEED compliance. For the LEED rating system, optimum start is required for systems that have greater than 10,000 cfm in the baseline. 

It's not required if it's less than that in the baseline, but it's often a good idea to put it into the proposed. If you want to learn more about optimum start, please see our theoretical video on what is optimum start.
