Modeling of Solar Radiation on Part Shaded Walls

The program described in this research produces average solar radiation on walls after shading effects have been considered by numerical analysis methods. After extensive testing, it is hoped that, by integrating a version of this program into existing systems, a more realistic solar heat gain may be obtained for the site. As a result of this, more economical systems can be installed that will operate at more efficient levels benefiting both the user (capital and running costs) and the supplier (more competitive quotes). The program developed appeared to successfully deal with the majority of shading cases that are liable to be met in load estimating. The program is quick and reasonably accurate (to within about 2% of hand calculation) with as few as 100 data points.
