Envi-MET is a useful tool for simulating wind speed at building heights and modelling microclimatic conditions around buildings, including wind speed around buildings and other structures. Envi-MET is used in this study to simulate wind speed toward buildi ng heights. When R2 = 0.8186, relative bias is-0.0775, and RMSE is 0.2578, the agreement between Envi-MET simulation and ground observation indicates acceptable agreement. With this establishment, it was discovered that the building's height and wind speed are not the only factors causing destruction; the less friction of wind with surface features will also increase the wind speed, as shown by the results of the vertical profile wind speed in relation to the toll way building's height. At a height of 13 metres, the wind speed is 3.5 m/s. Wind circulation affects the building at this elevation, causing damage to the roof and ceiling. Buildings and structures can sustain significant damage as a result of high wind speeds. When wind speeds are high, the wind's force increases, causing pressure differences on different sides of a building or structure. The findings of this study inform relevant parties of the impact of wind on building construction and how it may influence variations in wind speed. © 2023, Construction Research Institute of Malaysia.
