Note that when you load lighting data from template, the actual lighting casual gain is calculated by dividing the W/m2/100 lux data in the template by the required illuminance level as set on the Activity tab.
If 'Internal gains operate with occupancy' under model options is not set Task lighting has a specific operation schedule set under Task Lighting, otherwise these gains are synchronised with occupancy.
