Thank you for the advice,
how about doors, walls, floors and roof ? where I can simulate those ?
Thank you for your time
Have a great day today and a wonderful weekend

To Alex C and to add to the last email from Alex K, you might take a closer look at COMFEN and RESFEN.
Each focuses on quick assessment of window/facade performance with a minimal learning curve but using powerful analysis engines.
RESFEN (RESidential FENestration) is a two screen interface (text only) to DOE-2; with a one screen input it runs a highly defaulted "typical" house but allows all the fenestration related parameters to be selected and varied, and provides house energy performance and cost data for output. Download at http://windows.lbl.gov/software/resfen/resfen.html
COMFEN (COMmercial FENestration) is an easy to use but very powerful interface to EnergyPlus. It does full building systems analysis for multiple "spaces" - on an annual basis, with default HVAC/operating schedule etc. It is graphically oriented and "architect friendly", having been designed with extensive input and collaboration from A/E teams and consultants. It provides virtually complete access to design and analyze any fenestration system- you can select from 3000+ glazings from the WINDOW6 data data base, choose framing sytems, design the facade with multiple windows, add interior or exterior shading, daylighting etc It provides graphic access to all the EnergyPlus climate data. There are multiple options for graphic display of output from annual to monthly to hourly data; energy/peak/comfort/carbon, etc For 5 zones, on a standard laptop for an annual 8760 hr calc it takes 30-60 sec; It includes glare analysis of facades at user specified hours with a link to Radiance. The next version will include some natural ventilation strategies and some new cost databases. There are tutorial movies and a user manual; You can access free downloads at http://windows.lbl.gov/software/comfen/comfen.html
See sample output at http://windows.lbl.gov/software/comfen/4/comfen_screens.html
provide feedback or ask questions at COMFENHelp at lbl.gov<mailto:COMFENHelp at lbl.gov>
We plan to add additional new features this year so feedback is welcomed.

Hi Alex,
There's been a lot of good feedback on these lists. I think a question to keep in mind while picking a modeling software is: what is your target building and target output?
You mention envelope performance - I've used some fenestration (window) specific modeling tools in the past when the building type is appropriate and the level of detail needed is not as high as to require a full eQUEST/EnergyPlus model.
Comfen and Resfen developed by LBNL are great tool for commercial and residential analyses of fenestration impacts. I'm sure there are very many other tools that focus on components of a building. That may be an option for you as well.
>From one Alex to another, if I had to pick one, my vote would be for eQUEST as an accessible modeling environment with a great user-base (this list-serv and the archives) as well as many people teaching eQUEST classes across the country.
Cheers,

Speaking from an architects perspective and admittedly novice energy simulator, Equest was pretty easy to access, and after going to one of the Equest courses, that made it even more useful. Alex, however, your tag line indicated you are involved in houses, so in that case Equest may not be appropriate, unless they are large multi-family types.

Alex,
I would agree with Cheney here. The wizards available in eQuest will allow you to create and simulate typical buildings and various scenarios relatively quickly and easily and with a good level of confidence. The documentation which accompanies the eQuest download contains very useful reference and guidance documentation.
Good luck.
Chris

I do not think it is a good idea for a beginner to start with Energy Plus. Bear in mind, it is not so user friendly. Even a senior energy modeler may not be able to grasp it easily. Equest is more strait-forward to my mind.

My advise to Alex is to start with Energy Plus, as it has the most development put into it and the mose capabilities.
Also Open studio has some great information as to where to start. http://openstudio.nrel.gov/

Dear All,
The paper from referred to by Alex is no 6-7 years old. There has been a lot of movement in building simulation since then.
Has anyone published formally or informally anything since 2005?

Hi Alex,
welcome to the world of nerds ;-)
There is an intersting document to start with:
http://apps1.eere.energy.gov/buildings/tools_directory/pdfs/contrasting_the_capabilities_of_building_energy_performance_simulation_programs_v1.0.pdf
That will probably get you a nice intro. If you are into the maths and equations, check out Joe Clarke's book on building simulation.
Also Jan Hensen recently published one on building simulation.
Good luck and welcome!

Good afternoon
My name is Alex, and I'm new to building simulation world , and i saw you have many simulation software ,
1.from my understanding the most used ones are eQuest and Trace 700, is it true ?,
what the difference between these two,
2.i would like to simulate more building envelope, what software suit more for that ?
Thank you very much for your support and help
with best regard
Alex
