Simulation of shadowing

Shadowing simulation is an important tool for studying the impacts of direct and diffuse sunlight on buildings.

Such simulation can provide useful information in the following areas:

  • assessing the energy effects of solar radiation on and in (double) facades
  • assessing the need for, and effectiveness of, various solutions for year-round sun protection
  • determining the suitability of roofs and facades for thermal energy collection and photovoltaic energy generation
  • assessing the impacts of shadowing by neighboring buildings and of self-shadowing (in atriums, inner courtyards, as a result of building displacement)
  • determining how a building's own shadows influence existing neighboring buildings

Assessing changes in shadowing throughout the course of the day

Determining solar radiation in W/m² (annual, monthly or daily values)
