Sombrero

A PC-tool to calculate shadows on arbitrarily oriented surfaces. In designing both active use of solar energy (domestic hot water, photovoltaic) as well as passive solar architecture, shading and lighting of planes plays an important role. SOMBRERO provides quantitative results for shading of collectors or windows by buildings, overhangs, trees or the horizon. These results can be used either directly for visualization or as input for other thermal simulation programs.
