When you determine your building envelope for a baseline, a major renovation in an existing building, it's clear that "the baseline building design shall reflect existing conditions prior any revisions that are part of the scope of work ...".
But, the HVAC system?
I’m right if I choose the Baseline HVAC system from table 'Baseline hvac system type' in app G? Even if I have another HVAC system before the renovation? For example prior renovation a CAV system with no reheat and after the renovation a VAV system with reheat. But the modeled baseline HVAC system should be for an example a system 7 - VAV with reheat in the baseline. But the building envelop shall reflect the conditions prior renovations. I’m right? or wrong...
