RE: [EnergyPlus_Support] Some Tutorials And websites for energy plus

You changed the Wind Pressure Coefficient Type to SurfaceAverageCalculation. Why did you add the Wind Pressure Coefficient Array and Value objects and the External Node objects? These objects are not used when Wind Pressure Coefficient Type = SurfaceAverageCalculation. You have also entered other data that is not necessary. When I fixed these errors, the simulation found that only 2 surfaces exist for the airflow network simulation. I assume you still need to add 2 more walls and a roof to complete the simulation. I will let you do that.

ok!

I didn't get to turn this serializes below and when to the the simulation to conclude it seemed 4 warning.

If you have a rectangular building, you could change that input to SurfaceAverageCalculation and you would not need these additional input objects.

I need your help.

In your file, you have left blank the field for the wind pressure coefficient array name when you said the wind pressure coefficient type was INPUT.

AirflowNetwork:SimulationControl,
VentNatural, !- Name
MultizoneWithoutDistribution, !- AirflowNetwork Control

Look at the example file AirflowNetwork3zVent.idf. That file has the same input as yours and DID specify the coefficient array name. You will also need one AirflowNetwork:MultiZone:WindPressureCoefficientValues object for each face of the building (I only show 1, see the same example file)

Hi,
please send email at the related topic
for learning energy plus these are my suggestions.
1- if you want to have fewer problems, please change your version to 6.
2-for opening version 5 or older versions at the energy plus version 6 you have to use transmission tool that you can download it from http://energyplus.helpserve.com
3-please check sample file of energy plus that they can be related to your work and check your file and example file differences they are in "C:\EnergyPlusV6-0-0\ExampleFiles" ( if you didn't change the installation path)
4-download training files from energy plus website
http://apps1.eere.energy.gov/buildings/energyplus/energyplus_training.cfm
at the "Energy Plus University Course Teaching Material" after registration you can download training files that they are power point files (6.5 MB  zip file)
they are very useful
also if you checked the file that I emailed to you, I corrected your file in version 6.
I hope it is useful.

Hi Reza

I managed to do with that the version 6 is scanned the version 5. They put the severe returned in the old mistake. As it could correct it. I inform that I am still learning how to use the software.

Hi ,
Some websites that they have tutorials for energy plus.
There is an online tutorial, http://www.vibyor.com/tutorials
It's a brief tutorial made by Prof. Vishal Garg, from IIIT Hyderabad,India.
There is also a forum on vibyor where the participants of the course can
discuss their problems.
And another tutorial here:
http://www.labeee.ufsc.br/pos-graduacao/ecv_4202/ecv4202_doc.html
There is also the training material designed for University use on the
regular website (which is down until 11/16/2010 morning).
if some one know some thing else please add to this email
with Regards
REZA
