Each row is composed of hexagonal shaped apertures that are covered by 2 operable shields and they have the ability to pivot open and closed.
A rotary motor driven by an arduino microcontroller connected to a solar sensor, are placed at the end of each row, pulls the thread and slowly opens or closes the shields.
In a sunny winter day the shields are automatically opened to allow sun to enter the interior and warm the space.
