In the latest version of honeybee for daylight analysis, is it possible to apply a radiance modifier which varies over the year, say for a deciduous tree which looses leaves in winter. I know this is possible for energy simulations using the ep trans schedule, but not sure about radiance…?
The icon for the Dynamic shade group suggests this would be the component to use here, but I cant find much in the way of examples or any explanation of how these should be set up.
Hi @milog,
The Dynamic Shade Groups are not implemented in the recipes.
You can achieve a similar workflow by using Dynamic Aperture Groups, although it is not really meant for deciduous tree modeling. You need to add all your aperture to the same group, and then you can add Dynamic States with Dynamic State Geometry.
In the attached file you can find an example where there are two states for the leaves – the geometry for the leaves has different modifiers for the two states. The schedule of the different states is created in the post-processing by using integers. In the example there are two states, so the first state (with leaves) is 0, and the second state (without leaves) is 1. There is schedule month by month where Jan-Mar is state 1, Apr-Sep is state 0, and Oct-Dec is state 1. You make a more detailed schedule and more states to the aperture group to have more variety in the “amount of leaves”.
