In this lesson we're going to cover and create a VAV fan curve. To understand more about curves, which is a concept in almost all stimulation programs, please watch the theoretical video on curves where we cover an example of this. For those of you who know what a curve is and are just wondering how to import it, we're going to cover that right now. Moreover, we're going to cover something that you're likely going to have to do-- importing the LEED fan curve for a VAV system. Let's say you have a VAV system set up.
