1/ Why considering direct daylighting during the beginning of the research over time ?
Direct sunlight related issues must be controled.
>Using sun energy and avoiding overheating.
> Avoid Glare
=>Sun penetration fluctuates with time; it must ne simulated over time to identify Direct sunlight related issues. Depend of the project's mass designed at the beginning of the design phase.
quickly previewing the quantity of direct sunlight that will enter critical areas on a prpject over time.
