It isn’t as grey as you might think. Table G3.1#2 addresses the conditions that must be met to allow the addition to be modeled without the remainder of the building. If all these conditions are met, it is reasonable to use only the addition area to determine the Baseline system type. If the addition systems are not distinctly separated from the existing building systems, it is likely that the entire building would need to be modeled (all the listed conditions would not be met), in which case the total building area including the existing must be used to determine the Baseline system type.<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>Hope this helps.
