Re: [EnergyPlus_Support] Changing orientation of building

[Jose Torre-Bueno <jtorrebueno@xxxxxxx>]

Thanks

That is what I thought.  The behavior I need is to change the orientation of one structure.  I am trying to study the optimization of the angle of a solar array with respect to utility time of day tariffs.  I intend to run the same building with the solar array at different azimuth.  I have the array mounted on a shade structure.  I would like to change the azimuth by changing one variable but the only way I know how to change the azimuth of a structure is to calculate backwards through the trig to find the corners in rectangular coordinates.  Doable but tedious.  Is there any way to specify angles of individual structures or enter orientations in polar coordinates?

Hi Jose

The building rotation in the Building object applies to all structures, including shading. changes effects the entire model.

Does anybody know it it is possible to have two structures or a structure and a shade object and rotate them with respect to each other?  I believe the angle in the building object will apply to all objects specified in the file.

Hello Nick.

On the Building object you can specify the angle between the north axis and the y axis of the building. In the IDF editor, its under the Simulation Parameters group, right at the start.

Dear all

 

I need to study the performance of building at different orientation, how can i do that in idf file, keeping all the other envelop details same.

 

Thanks and Regards

Nick
