The solar radiation is a major factor for thermal condition in built forms. The residential and commercial buildings consume 45 to 55 percentage of the energy for thermal comforts. It was evident that the higher the energy consumption through fossil fuels leads to the remittance of CO2 in the atmosphere. Building industry in India is having predomi...

... Solar time and local standard time is different from each other. Local solar time is derived by the actual sun position on the sun path of each particular day, whereas the solar time is derived based on reference meridians [11]. Again the mean solar time can be obtained by the equation: ...
... The average output voltages from three solar modules for the first three days of each month was computed using [11]. The total average output powers generated by each solar panel with the corresponding tilt angles had to be computed using equation [12] and then summarized the result value in Table 1 as a sample for june inorder to reducecroding. ...
The solar power capacity depends on orientation angle of the solar panel. This study evaluates the angle dependence of solar power capacity for a summer season in 2017. Using three solar panels, with 10 Watt capacity each placed on a metallic frame to facilitate changing tilt and azimuth angles independently. Experiments were done for the first six days of three months, and the first three days of each month were used to measure voltages for different tilt angles by changing from 0° to 26° in steps of 2o. The remaining three days of a week of every month, the middle solar panel was fixed at a tilt angle that yielded maximum power while the two panels were moved with azimuth angles from 0o to 270 in steps of 3o to clockwise and counterclockwise with respect to the middle solar panel. A digital multimeter was used to record the circuit voltage of the solar panels with 10 ohms resistor serving as a load. Data gathering was done every ten minutes, during the daytime from 9:30 am to 16:30 pm. The study has shown that the maximum power output was obtained at the tilt angle of 4o in June and July, 2o in August and a season tilt was found at 4o. Maximum solar power outputs were obtained when solar panels facing east and west were oriented between 0o and 3o. This recommends that the maximum solar power production depends on the tilt angle of 4o and clockwise and counterclockwise of 3o orientation for this geographical location.
... Although, the study case of the sports building as shown is the main sports hall. These data are the basic step to work on climatic consideration to reduce consumption of conventional energy [4]. Nature of sun movement and natural light was responded to create formulation of movement and form. ...
Buildings not only can be resilient from environmental changing by passive design, but also have ability to adapt the environment by active system. By using deployable structure, this system can be provided by changing multiple form based on its purpose to cover the building. To provide these conditions, deployable structure need to be explored and analyzed to develop compatible structure in the building. Case of study in this research is Pajajaran sports building in Bandung. The research method is exploration of form and movement based on limited variables, there are activities and weather changing/climate condition. These variables formulated into two conditions, open and closed building. Open building state in sports building have requirement that either natural or artificial lighting should not cause glare in field area. So, natural lighting was simulated by using Ecotect Analysis to find solar path movement and shadow angle. The result of the solar path simulation shows that daily solar movement must be responded directly because high rotation rate and regular changes, while the monthly sun path does not require significant movement due to low rotation rate and insignificant changes. This study will show design process of deployable structure into sports building.
