GLASSCON is awarded to develop, engineer and install an innovative heliostat system on the DOME LIBRARY building, along with other façade applications. Designed by the renowned architectural studio ATELIERS JEAN NOUVEL. The structure is completely water and air tight, and provides efficient lighting to the interior of the library. Based on a solar algorithm which orientates the heliostat and rotates the installed solar louvers in small steps, light is guided to the library accordingly and optimizes optical comfort.
