Re: [EnergyPlus_Support] Wind Speed

[Dru Crawley <dbcrawley@xxxxxxxxx>]

Typical weather data collected at airports (most of the source data for EPWs) is measured at 10 m:

 

"Weather stations throughout the world (ref: WMO ? World Meteorological Organization) take their measurements at standard conditions:

• Air temperature is measured at approximately 1.5 m above ground
• Wind speed is measured at 10 m above ground
• Weather station is in a flat, open field with little protection from the wind."

from description of Site:WeatherStation object in EnergyPlus Input/Output Reference.

Does any body know what height the wind speed measurement in a epw is assumed to be taken at? 2m? 10m?

thanks,

Will
