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

Abstract

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 fagade. The smaller the tilted-angle of the fagade, 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 fagade, the more heat received by the building.
