Renewable Energy Potential by the Application of a Building Integrated Photovoltaic and Wind Turbine System in Global Urban Areas

Abstract

Globally, maintaining equilibrium between energy supply and demand is critical in urban areas facing increasing energy consumption and high-speed economic development. As an alternative, the large-scale application of renewable energy, such as solar and wind power, might be a long-term solution in an urban context. This study assessed the overall utilization potential of a building-integrated photovoltaic and wind turbine (BIPvWt) system, which can be applied to a building skin in global urban areas. The first step of this study was to reorganize the large volume of global annual climate data. The data were analyzed by computational fluid dynamic analysis and an energy simulation applicable to the BIPvWt system, which can generate a P max 300 Wp/module with a 15% conversion efficiency from a photovoltaic (PV) system and a 0.149 power coefficient/module from wind turbines in categorized urban contexts and office buildings in specific cities; it was constructed to evaluate and optimize the ratio that can cover the current energy consumption. A diagram of the distribution of the solar and wind energy potential and design guidelines for a building skin were developed. The perspective of balancing the increasing energy consumption using renewable energy in urban areas can be visualized positively in the near future.

Photovoltaic and Wind Turbine: A Comparison as Building Integrated Renewable Energy in Indonesia

“…Those needs should be fulfilled by maintaining the balance between energy supply and energy demand. This balance could be managed by the efficiency of energy consumption, design guidelines and strategies, and the application of renewable energy (Lee et al, 2017). All those data correlated to one concern; the energy sources come from fossil fuel that has negative impacts on the environment.…”

“…The significance of energy conservation in modern world cannot be overstated, efficient utilization of energy has important influence in improving economy at all levels of human endeavor [1,2]. No doubt, adequate and appropriate utilization of energy boost up any country's developmental activities [3][4][5]. Recently, research interest has emphasis towards efficient energy utilization and its conservation as the effective means of reducing energy consumption in buildings, thereby reducing maintenance cost [6,7].…”

“…While such BAPV systems generate adequate electricity, their transparent area fraction is limited, which often makes them unattractive in architectural installations. A number of recent studies have been dedicated to uncovering the potential of renewable energy technologies including photovoltaics for reaching the important goal of net-zero energy consumption in buildings and infrastructural installations [13][14][15][16][17][18]. Figure 1 summarizes three well-known commercialized and recent examples of the relevant technologies and also provides the data on the currently-available electric power generation capacities per unit wall area.…”
