Comment intégrer la lumière naturelle à la conception de fenêtres en aluminium ?

Effective daylighting blends window placement, glazing selection, and ceiling reflectance. Begin by optimizing window-to-wall ratio (WWR): target 30–40% on facades to balance illumination and heat gain. Position windows high on walls to capture deeper daylight, pairing with narrow horizontal aluminum clerestories. Use high-visible-light transmittance (VLT > 60%) low-E glass to admit ample daylight while controlling solar heat gain. Internally, specify aluminum ceiling panels with a light-reflective anodized finish or white powder coat to bounce daylight deeper into the space. Continuous ceiling panels above window head height can integrate light shelves—anodized horizontal surfaces that reflect daylight onto ceiling planes. Coordinate the panel reveal grid with window mullions for a harmonious ceiling-facade transition. Automated shading devices, such as interior roller screens mounted within the ceiling plenum, adjust transmittance based on daylight sensors. This integrated strategy leverages aluminum windows, facade panels, and ceiling systems to create bright, energy-efficient interiors with minimal artificial lighting dependence.
