The first step to achieving light control inside the building is to have an opaque structure. One of the typical problems that arise when achieving a building that is opaque to light is the need for the structure to have ventilation openings. These openings allow the entry of fresh air and the exit of stale air but, unfortunately, they also favor the penetration of light through the entrance and exit openings of the building. To solve this problem, light filters can be used that allow air circulation and absorb light. Light filters are made up of curved slats that reflect light from one side of the slat to the other. Each reflection absorbs part of the light, so it reduces its intensity. The curvature of these slats must be such that it offers a balanced combination when it comes to creating many light reflections without excessively interrupting the passage of air through the slats. Munters engineers have used state-of-the-art Computational Fluid Dynamics (CFD) software to achieve this design balance. The LFd can be installed in both inlet and outlet openings to achieve the necessary darkness inside the hall, even when the sun is shining outside. On sunny days, outdoor light levels can even reach 160,000 lux. After passing through the LFd, the light level can be reduced to as low as 0.12 lux, creating total darkness.
