[EnergyPlus_Support] Adjacent buildings and CAD files.

Mike:

Thank very much you for your explanation.


First let me introduce myself: I have a BS degree in Mechanical 
Engineering and I live in Lisbon, Portugal's capital city. I design 
small HVAC facilities. Up to now I have used only Direct Expansion 
systems, but I want to use Water-air and all-Air systems (both VAV 
and CAV). I would like to base my decisions after a carefully load 
estimation and energy analisys.

I understand that this group is primarily for e+ users, and I just a 
rookie in the business. However, the general questions I post will 
help me a lot understanding the "broader picture".

?	After zoning the site, if one is not sure about wich system 
to aplly, is it possible to run e+ just to calcule only the building 
thermal loads for each zone in the first place (with no HVACsystem 
defined), then chose the systems to use, and rerun the input file 
again?
?	The e+ takes in account the shadows created by adjacent 
buildings and structures? (it's an issue I haven't seen yet in the 
discussions I found).
.        As far is I know, there is a way to import CAD drawings of 
the site in a special format, in order to speed up the process of 
input file filling. When we do that , besides the building geometry, 
the wall U values, and doors and windows characteristics (if they 
are incorporated in the cad file)are also incorporated in the input 
file?

Thanks in advance,

Vítor
