One of the most important acceptance issues regarding implementation of the small-scale wind turbines in urban environments is related to the human comfort. Human perception of vibrations is very sensitive and thereforeturbine induced vibrations can havebig influence on the implementation of urban wind harvestingby small-scale turbines at the top of buildings. The aim of this work is to investigate increase of vibrationsin a steel building after installation of small-scale turbine at the roof.Comparison is made between floor vibrations influenced by wind action on the building only and together with the roof mounted turbine.Five story steel building with regular shape is analyzed with horizontal axis wind turbine (HAWT) on top with rotor diameter of 5 m. Turbulent wind profile is generated and used in time-history analysis of the building. Increased floor vibrations in the area around wind turbine installation are obtained.Results of the analysis in terms of accelerations arecompared t...o the requirements in relevant design codes.
