Assessment of Annual Energy Enhancement for Tall Building Integrated with Wind Turbines (BIWT)

Apr 06, 2015

This paper considers wind power as an important potential renewable energy source in tall buildings due to the possibility of accessing greater wind velocities at higher altitudes. In addition, air-flow patterns around buildings are considerably influenced by tall buildings’ geometrical characteristics.

This paper evaluates the suitability of Building Integrated with Wind Turbine (BIWT) power coefficient as a measure to inform the architectural integration of wind turbine into tall buildings design. The objective is to know whether higher BIWT power coefficients always guarantee a greater annual energy output regardless of BIWT location and site. This paper assesses the sensitivity of ‘Local Weather,’ ‘Building Direction’ and ‘Surrounding Terrain’ on the BIWT annual energy output. The study outlines three BIWT case studies and obtains the power coefficient profile. Calculating the power coefficient profile for three BIWT case studies, the study carries on by approximation of annual energy output for each case study at four different locations. The comparison of the annual energy productions tells how much local weather patterns, building direction, site terrain, and the BIWT typology influence the annual energy output for a location.
