Reuse shadow calculations for iterative / parametric building mass simulations
Is there a way to seperate the shadow calculations from the E+ simulations and implement a previously calculated shadow calculation?
We are setting up our own parametric simulation tool where we will simulate thousands of iterations of a building design. Some of these will have changes that will affect the shadow calculation results (shading, glazing%, etc) and others not necessarily (insulation value, SHGC in glazing, etc). Since shadow calculations can take up quite a bit of time in some simulations and we in general want to reduce simulation time since we are doing thousends of them at the same time I was wondering if there is a way to "reuse" older shadow calculations that are applicable to a specific iteration, or if the shadow calculation is native to the E+ simulation and will always be simulated.
These simulations are for a first phase / schematic design phase, so we are not striving for high accuracy, but more a general overview of the options in variations for a building mass.
