Effect of Tilt Angle of Building-Integrated Wind Turbine and Photovoltaic Façade on Wind Pressure and Solar Radiation

This study investigated the potential impacts of wind pressure and incident solar
radiation on a building tilted façade installed with micro wind turbine and photovoltaic panels as a second skin façade for generating electricity. The wind pressure will affect wind turbine
rotation, and solar radiation will affect the energy produced by the photovoltaic. The study used
simulation modeling software to analyze the wind pressure and solar radiation received on the tilted façade. The research found that the force received by the tilted façade is more significant than that received by the 90° tilted façade. The smaller the tilted-angle of the façade, the more
radiation received by the PV panel. Conversely, the larger tilted-angle of the building façade, the
less radiation received by the photovoltaic, despite the wind pressure received by the wind turbine being higher than that received by the 90° tilt façade. However, the more radiation received by the façade, the more heat received by the building.
