[Bldg-sim] Energy needs at an early design stage

[Dennis Knight]

All,
This has been a great thread.  My experience has been that the early stage
models for building orientation and envelope optimization are not of much
use, other than the insight gained from the exercise, when you move from
that phase of the project to system sizing and equipment selection during
the design phase, whether your are working with a manual input workflow
into a simulation tool or trying to automate the input through Sketchup,
Revit, Bentley, ArchiCAD, etc.  Load calculations, equipment sizing, air
distribution system device and distribution system design and selection
pretty much demand room-by-room analysis.  Its hard to take conceptual
models, exterior surface area models, massing and "shoe-box" models and
grow them into room-by-room models using the same original input files.
 I'm very interested in what you all have to say about this process and
does any of these tools make the transition from concept to full blown
design any less painfull?
Dennis
