Estimating Wind Frequency for Natural Ventilation at Remote Sites

Using the wind pressure difference method to estimate the cross ventilation potentials of a building at a particular site, the appropriate wind frequency data at the building site are important (Aynsley et al, 1977, Su, 2001). This study investigated wind frequency data available from the data recording site at Auckland airport and discusses how to obtain the building site wind frequency data from the original wind frequency data recorded from such sources.
