Quantitative Investigation on Shaded Area of Blue-Mosque Domes in Tabriz-Iran

The numerical investigation of computing the rate of radiated solar-energy requires equations as a function of solar-time according to the radiation angle of the sun (β) in the latitude 37°N and the shape. This paper implements the Lagrange interpolation to obtain the equations of normal diagram of elements based on data obtained from surveying. Also the method of Hann-window equation used to estimate the sun path. Albeit, the solar radiation angle effects on the length of element`s shadow on the ground but it is a function of solar-time too. The parameters of the dome traits did compute using the solar-geometry principles in a coexisted function of time to reach a viable equation. The amount of absorbed and wasted energy is presented by surface analyses in the all sides simultaneously
