Conducting energy simulation within the grasshopper environment makes an iterative work flow much more simple. The example below, using the DIVA plug-in, shows illumination values (represented by a gradation from red to blue) under the red canopy. Note the data tags. These values are available to shape surface strategies.
The example below uses the Geco plug-in to integrate with Ecotect. Here the total incident solar radiation is represented as a topography from red (hot) to blue (cool). The definition requires a .wea file.
