摘要： This chapter intends to propose a smart city for utilizing renewable energy sources as much as possible. For example, the city consists of many buildings and the buildings are thought to be an obstacle to natural wind flow. If the wind movements through building layouts are controlled, then there is possibility that the wind can be utilized for power generation through wind turbine. In addition, solar power can be utilized by installing solar panels on the roof and/or side wall of the buildings. The proper building design can help to utilize the available solar radiation for generating power and heat through solar energy systems. For designing a building in smart city, building dimensions and layouts are very important for effective utilization of wind speed and solar radiation. It has been observed that, there is very limited research and project works, which are investigating these issues. This chapter is providing study on large scale power generation by wind turbine and PV systems integrated with building and in the city. In this study, the horizontal axis wind turbine is considered for integrating with city infrastructure and the output of commercial horizontal axis wind turbine is much larger compared to that of the commercial vertical axis wind turbine. Additionally, the building integrated with PV systems is considered. The proposed schematic of smart buildings integrated with wind turbine and PV system is given in Figure 1.
