LB Wind Speeds Datum

#1

Hello,

i have a query re wind speeds.

a) Wind Boundary Profile: Wind Speeds @ various height. What is the datum i.e. 0.0, is it the sea level?

b) Outdoor Comfort Model: It considers wind speed @ 10.0 meters. However, in windy countries like NZ, discomforting winds (approx 14m/s) winds blow at ground level. Hoe do we take that into consideration in our Outdoor Comfort Model?

Kind regards,

Hi,@Agneesh
For question a, the datum is the local ground level.
For question b, you can use ladybug wind profile compotent to calculate the pedestrian speed.

Hi Mingyang,

thank you for your response. Some cities are built on a hill. There could be significant height difference b/w high and low point of a road, as a result affecting the comfort due to wind. How do we tackle that?
