Nick et al,
I still think DesignBuilder offers good value for money when you
compare it to the cost of the pro-version of sketch-up. It imports dxf,
pdf, tiff, bmp, jpg (for 2d extruded modelling) & gbxml (for 3d importing).
Ok, perhaps it isn’t quite as pretty as SketchUp in places, but let’s
face it, as building physicists we’re generally not interested in
architectural fancifulness. We are interested in boxes (well more or
less) that make the maths quicker. DesignBuilder does all that just the
same. It also has the advantage of the CFD tool module that allows you to
look more closely airflow distribution based on the results from your EnergyPlus
simulations which are directly linked if you want them to be and produces mean
age of air results, that you could use for other ventilation & comfort
analysis.
Just my tuppence/2 cents worth.
Cheers
Paul

Subject: Re: [Bldg-sim] [EnergyPlus_Support] I need advices for choosing
a GUI
The current version of free sketchup (as of this month I
believe) does not support .dwg importing, actually. If you continue using
any older version – it shouldn’t lose this functionality (keep your
installation files). The Sketchup development team has been clear on
their intent to continue .dwg and other proprietary format file support in the
Pro version.
**A moment on my soapbox**
Our office took this as a cue to recognize that the free version
of Sketchup is explicitly intended for educational/trial purposes, however
powerful it may be – not for professional design use. Our office
purchased a Pro license in response to ensure continued support of
import/export of .dwg and other formats we use. I’d encourage
others on bldg-sim to consider this carefully. The cost:benefit ratio of
the free version of Sketchup, for many of us, is pretty extraordinary. To
top it off it’s actually fairly inexpensive as far as professional design
tools go.
**Stepping off the soapbox**
On a Sketchup-related note – I haven’t mentioned
this on [bldg-sim] yet, but Sketchup-savvy users using a version with .dwg
export support can actually export their models into AGI32 for photometric and
rendering lighting/daylight studies after a little work in CAD to ensure a
clean import. I might write up an illustrated guide or post the full
scoop here at some point in the future, but for those interested in learning
immediately I’ll just say to head over to the AGI32 forums to find a lengthy
post (intended to troubleshoot other AGI32-specific issues) where I composed a
pretty decent outline of the process to start.

Free sketchup is not going to support dwg importing for much
longer.

In what sense?
If you mean it doesn’t have every single capability of
modeling like the IDF or Text editor would, yes. But nothing does. It’s
hard to keep up with the E+ developer cycle ;-)
If you mean it doesn’t run off Energyplus 3.0. It does.
I don’t use it because it’s too expensive. I prefer
OpenStudio and the IDF Editor/Textpad because you have access to all the
capabilities that E+ has to offer, but it took me years to become even semi
comfortable (read: confident) with modeling through a txt file.
Either way maybe this should be moved over to BLDG-SIM.

Yes, but Hevacomp does not have the
capabilities of EnergyPlus.

You

Hello;
My feeling is that their currently is not a *perfect* GUI for EnergyPlus,
especially if you're interested in interoperability (ie IFC, gbXML, etc).
Designbuilder seems to be getting closest in this regard, but when I tested it
a while ago I found the modelling interface to be a bit clumsy and restrictive.
OpenStudio is not bad, but still needs a little work to be practical for every
day use (for instance, to my knowledge there is currently no good way to
specify a heat transfer surface's adjacency conditions). I currently use
ECOTECT, which had a lot of promise when I started using it three years ago but
has progressed exactly zero since then. I don't know much about the other
system you mention.
To summarize: the three you mention will all probably work for you, and each
have their own advantages and disadvantages. If you're specifically interested
in IFC compatibility, I'm not sure about the status of DesignBuilder in this
respect, but neither OpenStudio nor ECOTECT currently have this capability.

Hello,
I want to learn EnergyPlus but I need a GUI. As it is a new activity for me, I
would like to find the better couple [E+/GUI] regarding my needs. I am mainly
interested in building energy simulation, particularly on the topics of energy
efficiency and the smart use of solar energy for solar passive designing. I saw
a lot of software on the web : Google Sketch Up with Openstudio, Designbuilder
(well described at Harvard), Ecotect...
How can I make the best choice? My choice will use the IFC standard. I saw
another software : Digital Project of Gehry Technologies which is based on
Catia (Dassault Systemes) that works with IFC standards, but has anyone made
simulation with [E+/this soft]?
Could you give me advices, please...
Best regards
