7.2.5. Units for sun and wind
The display of sun intensity is in lux or kilolux and is shortened in the display to lx or
klx. The value 1 is reached even with overcast skies, 20 klx if the sun has just come out
again and 100 klx is reached when there are cloudless skies at noon. Experience indi-
cates that extending shades above 40 klx is to be recommended.
The display of wind speed is in meters per second and is shortened in the display to
m/s. Depending on the position of the building and the installation position of the
weather station, different values may be optimal in order to protect the shade or win-
dow. Observe the response of the awning or blinds or the window to wind and then
correct the wind value accordingly.
The following table should make it easier to find the optimal values for your situation:
