[EnergyPlus_Support] Re: Wind speed (power law + profiles)



hi,

Thanks for the help!
I calculated the wind pressure on my windows. I have a 15m high
building with 2 windows on at 12m the other at 3m (in opposite walls).
For the building at 12m the calculation in the engeneering reference
are correct. But if i use them for the window at 3m height, is get BIG
differences.
The odd thing is that if i use the refence speeds given by EnergyPlus
(so i guess out of the weather file?) the calculation is correct?
Does anyone have a explenation for that??

greetings,
Sebastian
