heal.abstract
This dissertation focuses on a small scale wind turbine placed on a building. The aim of this thesis is to study the effects on the urban areas on the electricity production. The initial investigation put emphasis on the performance of the wind turbine which was calculated by using software, called QBlade, along with the assistance of some dif-ferent assumptions (conclusions) for the effects of the urban area and buildings regard-ing the velocity profile. Finally, I want to thank my supervisor Professor Georgios Giannakidis for his guidance, his patience and his time.
