Soebiyan V., Bobby Saragih J., Tedja M., 2017, Study on High-Rise Building Using Wind Energy at Humid Tropical Climate, Chemical Engineering Transactions, 56, 241-246.
In Low Carbon City it is important to reduce the emission of greenhouse gases (GHG). It means buildings have to reduce the energy consumption of fossil fuel and take action to use clean energy such as wind energy. The higher altitude, the higher wind speed. Wind speed as a function of altitude has a chance to be used in high- rise buildings. Indonesia is a humid tropical country, which generally has the character of relatively low wind speeds. In another hand, high-rise buildings have considerable potential value to utilize height as a factor to obtain sufficient wind speed. This study aims to identify the potential for wind energy in high-rise buildings in humid tropical climate. Problems focused on the design arrangement of wind turbine type on the building and the potential energy can be harnessed. This research was conducted in suburban areas where the roughness level is lower than the city centre. This study focused on assessing the potential of the wind on tall buildings in a built environment in suburban areas. The research method is quantitative research which the variable is observed from wind speed data. Research developed by the experimental research method with CFD simulation to meet the built environment wind profile for further analysis. The variable data is observed from field measurement and local wind speed data. Case study takes on campus Bina Nusantara Alam Sutera as a case of the building which represents a type of high- rise buildings in suburban Jakarta area. This study shows at least five types of possible arrangements which can be applied to buildings. This study presents the alternative use of wind energy utilization at Bina Nusantara University as a cross-subsidy scheme. Wind energy can replace 3.27 % of main building energy consumption equal with CO2 emission reductions as 127,650 kg CO2.
