Zoning is a huge part of the GREEN Revolution in HVAC.  Studies show HVAC Zone Damper Systems can save 20%, or even more depending on how many zones and setbacks per day.  The combination of setback thermostats and zone dampers only heating or cooling thise zones that need it, can save substantially over single zone systems.  For those who continue to use separate HVAC units, this is NOT GREEN.  Just look at doubling the expdended energy, materials, transportation in making that second unit.  Plus the initial cost and added connected load to the utility.  Zoning with dampers is GREEN in so many ways over single systems and when it comes to dual systems, zone damper systems are the only way to go.  Granted some homes and building are large enough to require an extra unit when the load exceeds 5 Tons, however then each unit should be zoned.
