An approximate calculation method for parallel and diffuse solar irradiances on inclined surfaces in the presence of obstructing mountains or buildings
This paper presents an approximate theoretical method to calculate solar irradiances received by inclined surfaces in mountain valleys or city streets. Results can be used in mesoscale and urban dynamic modelling.
A fast approximate method for the calculation of the infrared radiation balance within city street cavities
The approximate calculation method for diffuse solar irradiances in street cavities presented in an earlier paper is extended to include infrared flux densities. By expanding the infrared sky radiance as a truncated trigonometric series, it becomes possible to solve the integrals representing the obstruction of the sky analytically. An example is worked out to demonstrate the numerically very efficient calculation procedure.
