Energy simulation misunderstanding

Hello All,

I’m running the energy and daylight simulation for a room that features a large aperture, which is characteristic of the vernacular architecture known as “Rawshan.” However, the UDI output changes depending on whether the perforations are open or closed, while the EUI remains unchanged, as shown in the photos. Can anyone please interpret the situation? I really want to see how much energy is consumed when the perforation is opened and closed.

Best Regard,
