The stairs at the entrance of the energy house provide access to other parts of the house. There are 14 circles with sensors and sound on the stairs. When these circles are pressed, each one sounds a note. The notes will be arranged in sequence and there will be a total of two of each note along the stairs. On the side of the stairs, there is a turbine with a solar panel. The reflective panel on the roof is steered by the steering wheel inside the room. When the sun's rays are reflected from the reflective panel to the solar panels, energy is generated and the turbine rotates.
