In this study, a six storied commercial building located at the Dhanmondi area in Dhaka city is used as the wind energy harvesting site. A small wind data logger is installed at the rooftop of the building to record daily wind speed and directions. From April 2017 to March 2018, the recorded data for one year is analyzed using Weibull Distribution Functions. Three statistical methods are used to determine and compare Weibull parameters. The analysis shows that the Shape factor of the site is 1.42 and the scale factor of the site is 1.96 m/s. The highest values of these parameters are found in June which is 2.53 m/s and 3.38 m/s. The Mean wind speed of the site is 1.77 m/s and the highest speed is also observed in June which is 2.99 m/s. To estimate yearly energy production three different wind turbine models ‘Aventa AV-7’, ‘DB-400’ and ‘Archimedes AWM-1500D’ are used to do the estimations in a mathematical approach. The possible wind power production capacity of the site would be around 109498.3 Wh to 149750 Wh per year by using ‘DB-400’ and ‘Archimedes AWM-1500D’ respectively. The projected energy density of the site is 10.26 KWhm-2 . Aventa AV-7 is not suitable for small building but future high rises like The City Centre, Dhaka may include such turbine applications in the design. The findings would be helpful for prior decision-making sessions to install small wind turbines in Dhanmondi and its neighboring areas of Dhaka city
