Patent ID: 10684399

Abstract:
In an aspect, a chromatic facade unit for being attached to a wall (1A) of a building (1) is disclosed that can form a facade (3) of the wall (1A). The chromatic facade unit (11) comprises a support structure (15), a chromatic reflective layer (17) formed on the support structure (15), the chromatic reflective layer (17) comprising reflective layer (43) and a chromatic diffusing layer (41), wherein the chromatic diffusing layer (41) is configured to provide for a specular reflectance that is larger in the red than in the blue and for a diffuse reflectance that is larger in the blue than in the red, and the reflective layer (43) is configured to reflect visible light having passed through the chromatic diffusing layer (41). The chromatic facade unit (11) comprises further an absorbing medium (47) provided in or on the chromatic diffusing layer (41) and/or the reflective layer (43), wherein the absorbing medium (47) is configured to absorb preferred radiation in the infrared spectrum and less in the visible spectrum. Furthermore, respective chromatic window units are disclosed to comprise a chromatic diffusing layer (41) and an absorbing medium (47).
