Smart glass, with and without user (IMAGE)
Caption
(a) If no user is present in summer all mirrors switch vertically, keeping solar heat outside. This saves huge energy by minimizing heat transfer. (b) Once user presence is detected by sensors in summer, upper mirrors open and reflect daylight to the ceiling area. The room stays cool where no user is standing, saving energy on climatization. Parts of the room far away from the window can be efficiently illuminated by daylight, saving energy on artificial light. (c) If no user is present in winter, all mirrors open and harvest energy by reflecting solar radiation onto a wall, acting as a radiation heater. This saves energy for heating. (d) Once user presence is detected in winter, all the mirrors will redirect the complete solar radiation to the ceiling to minimize glare. Now, the ceiling acts as a radiation heater, saving heating energy.
