  • electricidad generadaElectricity generated in 35 years - 30.125 kWh
  • puntos de luzTotal light points operating 4 hours a day in 35 years - 59 lighting points
  • emisiones CO2 evitadasAvoided CO2 emissions in 35 years - 20 CO2

The skylight enables the passage of daylight, facilitating the natural illumination of the courtyard while preventing the overheating of the building due to its solar (g) factor of between 5% and 40%, this making it an optimal choice for the prevention of the greenhouse effect, particularly in warm climates such as that of Valencia.

 

Furthermore, due to its photovoltaic properties it generates over 1,000 kWh yearly and prevents the release of almost 1 ton of CO2 each year. The total installed power capacity is 5.1 kWp.
