Daylight modeling

Daylight modeling

Intent: 

To support circadian and psychological health by setting thresholds for indoor sunlight exposure.

Surrounding buildings must be considered in the simulation. The daylight simulation submitted should be accurate at the time of WELL documentation submission. However, if there are future surrounding buildings planned by the same developer as the WELL project, the simulation submitted should take those into account. The team will not be held accountable for future developments on adjacent parcels that are outside of their control.

Yes, skylights should be included when calculating spatial daylight autonomy and annual sun exposure.
