Abstract :This study provides a comprehensive energy, economic, and environmental analysis of a commercial vertical-axis wind turbine (VAWT) for urban-scale applications. In accordance with the objective of this study, Doğuş University has been considered as a case study for conducting these analyses. In the analyses, wind speed data obtained from the meteorological station closest to the university, along with the technical specifications of a commercial vertical-axis wind turbine with a rated power of 5 kW, were considered as the basis. In the energy analysis, the amount of electricity generated by the turbine is calculated, while the economic analysis determines the revenue from electricity production, the additional revenue from the reduction of greenhouse gas emissions, and the total annual revenue. Additionally, the environmental analysis evaluates the potential for CO₂ emissions reduction. As a result of the study, the power density was calculated as 41.76 W/m² and 41.3 W/m², based on the Weibull distribution and meteorological data. Furthermore, calculations for a single wind turbine indicated that 2062.6 kWh of electricity production and a reduction of 947.98 kg of CO₂ emissions could be achieved in 2024. From an economic perspective, the total annual revenue is determined to be $241.10, with a Levelized Cost of Energy (LCOE) of 0.193 $/kWh. Based on the findings, it is believed that this study can play a guiding role in the planning and evaluation of wind energy systems for similar buildings and urban areas.
