My idea is to create a self-sufficient LED illuminated façade. The color of the façade is changing according to atmospheric parameters, like a forest changes its colors along the seasons of the year. The changing color of the RGB LEDs makes the façade of the building different every night, creating an item in the city.

The interactive lighting system of the façade brings joy and hope to the people.

The RGB LEDs are placed in aluminum perforated tubes; each tube is composed of two RGB LEDs, a photovoltaic cell, a microcontroller (CPU), a battery, a light and a temperature sensors. The façade absorbs energy from the sun and transforms this energy to electricity.
