This paper, is part of a research investigating variables affecting the performance of urban wind turbines, specifically roof mounted wind turbines. These variables include wind direction, roof shape, building height and surrounding urban configuration. Computational Fluid Dynamics (CFD) is the tool used for assessing wind flow around the investigated cases. The CFD simulations are validated by comparing the results with in-situ measurements and wind tunnel tests results for wind flow around a surface mounted cube in a turbulent channel flow. Results show that for each roof shape there is an optimum mounting location for roof mounted wind turbines and among the investigated roof shapes, the barrel vaulted roof had the highest accelerating effect on wind flow above the roof. Also, it is evident that changing wind direction, building height and surrounding urban configuration had an effect on choosing the optimum mounting location and the energy yield. In addition to presenting the results of the simulation work, this paper focuses on presenting the results of the research highlighting the proposed technology of wind turbines to be used in the vicinity of buildings and the effect of the investigated independent variables on the wind velocity and turbulence intensity at the wind turbine’s proposed mounting location. In light of the obtained results of the research, the paper concludes by discussing how architects can implement the available wind assessment tools and their knowledge of the design process in providing an informed decision regarding integrating wind turbines within the built environment.
