Re: [EnergyPlus_Support] Floor Multipliers



Thanks for your reply, Brent.
 
When you say the Z-coordinate should be an average, I would still have to match that Z-coordinate with the roof/ceiling of my zone underneath I suppose. So in that case, my lower most floor is affected?

The geometry stays where it is described. 

 

For a high rise buildings so the z-coordinates for the multiplied floor should be an average for all floors being modeled.   Unless there are neighboring buildings that are shading yours, the solar affects are not adjusted for height.  However, the outdoor air temperatures and wind speeds are adjusted for height and these can be significant for really tall buildings.

Hello,

 

When a Zone Group-Zone List object is used to implement floor multiplication, does doing this place the floor above the typical multiplied floor at a height it actually is present in the real building or it stays as it is drawn in the model? Would there be significant differences in solar effects if the height is not reflecting the real height of the floor (like for a 30 or 40-story building)?

 

Thank you.

 

Regards,

Vinay
