Arinna is developing ultrathin solar panels using new materials for spacecraft, aiming for efficiency and durability in space applications.
On the south and east facades, photovoltaic panels are installed to capture solar energy. Several of these panels are mechanically operable, adjusting their angle according to the season. During winter, they remain vertical to optimize solar gain, while in summer, they tilt open, creating shaded and rain-protected pedestrian areas. The north and west facades, which face residential zones, employ perforated cladding with built-in planting troughs. These elements form seasonal green walls that contribute to the building's ecological performance while softening its visual impact.
