Data:

• Total area - 176 M²
• Electricity generated in 35 years - 255,960 kWh
• Total light points operating 4 hours a day in 35 years - 502 lighting points
• CO₂ emissions avoided in 35 years - 171 Tons of CO₂
• Barrels of oil saved in 35 years - 151 barrels per m²

This skylight combines amorphous silicon modules of varying degrees of transparency and colours which form a mosaic inspired by the neoplasticism of Piet Mondrian. Besides, due to an installed power capacity of 6.7 kWp it can generate almost 9,000 kWh of energy per year, and prevent the release of 6 tons of CO₂ .

Part of the power generated is sent to be stored in batteries, and the rest is sent to the grid for the building’s own consumption.
