Re: [EnergyPlus_Support] Changing orientation of building





Nick,

Why the wall opening area @ East is 625.08 (m2)?  Is should be 417.54 (40 % of 1043.85) according to you. For some reason wall area  @ east is addition of 207.54+417.54= 625.08

PS

Thanks Pedro,
 
But when i changed the orientation to 45deg, the window wall ratio summary is as follows (earlier WWR was 40% on all 4 walls). But here in South it indicates zero.
 
Can anyone help in explaning this.
 

Window-Wall Ratio

Total

North (315 to 45 deg)

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
