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.

Energy conservation has become a significant concern around the world as buildings are built taller and consume more energy—about 30–40% of all primary energy is accounted for by buildings [1]

Summary
Energy conservation has become a significant concern around the world as buildings are built taller and consume more energy—about 30–40% of all primary energy is accounted for by buildings [1]. Installing a wind turbine on building façade should consider the shape of the buildings because it is a significant determinant of airflow patterns around buildings, and the wind flow is much dependent on the precise form of the architecture [5,6]. The shape of the building affects the wind flow and the incident solar radiation on the building façade, which is the primary energy source for the BIPV system. An innovative building-integrated wind turbine and photovoltaic and (BIWtPv) system is proposed as a second skin façade that produces electricity and reduces heat received by the building. As a Savonius-type wind turbine is installed on the building, the wind pressure and solar radiation received by the PV installed on the second skin façade should be analyzed
