[Bldg-sim] IES-VE Energy

Graham,
The comment below stands out which might also be the reason for not using EnergyPlus on large projects.
- DOE-2.2 runs much quicker.  For comparable 30,000 m2 buildings I would say DOE-2 runs in 1 minute and IES VE with an APhvac network probably 1-2 hours.  If you through in Macroflo it probably adds another hour of simulation time.  As a result iterative trial and error debugging has to be done on a 1-2 week period.
Large building projects (1 to 10 million sqft) with up to 1,000 zones and 70 systems ranging in size from 10,000 to 200,000 cfm (pardon the English units - the USA & the Bahamas are not going to switch to metric) require several iterative runs to get the input errors fixed.  Breaking up the project into small pieces is not a solution since it affects demand costs, central plants and other components.  I have worked on such projects using DOE2.1E and TRACE600/700.  
eQUEST is not suitable for such projects either.  One of its limitations is that you cannot enter the space names shown on architectural drawings. Others include assuming all the input data and making all the decisions for you when you enter the type of building.  1000 zones means 1000 infiltration schedules and multiples of other building components. It is unrealistic to check all the input created by eQUEST for errors. Fixing everything to match the exact project data has to be done in detailed edit.  Detailed edit means you lose access to the graphical method of creating the building model from AutoCAD drawings which is the main benefit of this program.
