If I compare the EnergyPlus output variable "Environment: Site Wind Speed" to the corresponding epw weather file, the windspeeds don't always correspond ( although δmet, αmet, zmet = δsite, αsite, zsite in the formula Usite=Vmet(δmet/zmet)^αmet * (zsite/δsite)^αsite ) (Formula extracted from: "Local Wind Speeds Calculations" in the Engineering Reference) Does anybody know why? Sometimes the windspeeds do correspond. Sometimes the difference is bigger than 1,5m/s.
