The aim of this study is to design and propose the building model integrated with solar panel and wind turbine for the purpose of realizing the smart city. The number and angle of tilt of solar panel installed on the roof of the building are investigated considering the effect of shadow for some cities in Japan. The power generation characteristics of solar panel installed on not only the roof but also the wall of the building are also investigated assuming the building model to be installed in Tsu city. In addition, the power generation performances of the photovoltaic as well as the combined power generation of photovoltaic and wind turbine which are integrated with the buildings are compared with the power demand of the buildings. To estimate the power generation characteristics of the proposed model, the statistical meteorological data base is used. As a result, the optimum angle of tilt is 0 degree irrespective of investigated cities since the number of solar panel is the largest. Though the power energy generated by solar panel installed on the roof covers the most part of energy demand of the building, the addition of solar panel installed on the wall is effective to cover the energy demand through the year. The combined power generation of photovoltaic and wind turbine is effective when these power generation systems perform complementing the weakness of each system, e.g., the wind turbine covers the energy demand in night.

The aim of this study is to design and propose the size and layout of buildings which provide the better wind speed distribution for the higher power generation of wind turbine. A building model whose layout is like nozzle is proposed to obtain the acceleration of wind blowing through buildings due to contracted flow between buildings. In addition, the effect of the angle between two buildings on the power generation performance of the proposed building model is also investigated. For the feasibility check of installing the building model in some cities actually, the power energy output of wind turbine is investigated by considering the meteorological data such as wind speed and direction distribution for Fukushima city and Tsu city as an example. As a result, the proposed building models which have the angle between two buildings like nozzle of 90, 135 and 180 degree can provide the wind acceleration at the back of buildings for the wind blowing from the main wind direction and the angle of 135 degree is found to be the optimum building layout. In the case of installing the proposed building model in Fukushima city and Tsu city, the wind power energy output in winter is higher while that in summer is lower irrespective of the buildings angle. The interaction between the change in frequency distribution of wind speed direction through the year and the location of open tip of building model decides the power generation characteristics of the proposed building model.
