The first step in achieving light control within the building is to create an opaque structure. One of the typical problems that arise when creating a light-opaque building is the need for ventilation openings in the structure. These openings allow fresh air to enter and stale air to escape, but unfortunately, they also allow light to penetrate through the building's inlet and outlet openings. To solve this problem, light filters can be used to allow air circulation and absorb light. Light filters consist of curved slats that reflect light from one side of the slat to the other. Each reflection absorbs some of the light, thereby reducing its intensity. The curvature of these slats must be such that they provide a balanced combination of creating multiple light reflections without excessively disrupting the airflow through the slats. Munters engineers used modern computational fluid dynamics (CFD) software to achieve this balance in the design. The LFd can be installed at both the entrance and exit openings to achieve the necessary darkness inside the building, even when the sun is shining brightly outside. On sunny days, the outside light level can reach up to 160,000 lux. After passing through the LFd, the light level can be reduced to 0.12 lux, creating complete darkness.
