Strong winds in the vicinity of the LIGO Hanford detector limit the operation time of the interferometer. The wind pressure on the observatory buildings introduces ground tilt that causes significant low-frequency noise. Reducing the influence of the wind is therefore crucial. Building a wind fence to shield the affected buildings, namely the two end stations, is planned. In this report the results from finite element simulations of different methods to mitigate the influence of the wind on the detector are discussed.
