Does anybody know if Autodesk considering of adding system for smoke extract, pressurization, and fresh-air? The only system in 2011 is supply, return & exhaust in which having requires different calculations.
I know the fact that exhaust may vary what type of air we are extracting from an area, but separating the smoke extract would have different approach when it comes to unit selections.
It would be better also to add refrigerant piping systems and separate from the hydronic system.
