Re: [EnergyPlus_Support] Changing orientation of building

[Pregas Srinivasan <pregas@xxxxxxxxx>]

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

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)	East (45 to 135 deg)	South (135 to 225 deg)	West (225 to 315 deg)
Gross Wall Area [m2]	3125.39	518.85	1043.85	518.85	1043.85
Window Opening Area [m2]	1250.16	207.54	625.08	0.00	417.54
Window-Wall Ratio [%]	40.00	40.00	59.88	0.00	40.00

 

Thanks in advance.

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
