Shading & carbon — Valencia

Valencia (ES, 39.5° latitude, 1740 kWh/m²·yr GHI) is preset on the calculator below. Adjust the area and the louvre position to model your specific site, or pick a comparison city to see how the climate affects the headline metric.

What this means at this location

508 kg CO₂/year is roughly equivalent to a small mature tree absorbing CO₂ for that same year, or 4 600 km in an average EU car. Over the 25-year service life of a Luxa Sereno frame, the cumulative 12.7 t of CO₂ avoided in Valencia translates into roughly 50 short-haul flights' worth of emissions.

METHOD
Solar irradiance from JRC PVGIS-5 (ERA5 mean 2005–2020), per major city. Direct-beam fraction averaged across the year. Cooling COP = 3.5 (typical air-air heat pump per EN 14511). Grid CO₂ factor uses each city's national grid intensity (EEA 2024). Outputs are first-order estimates for orientation decisions, not a substitute for a building-energy simulation (TRNSYS, EnergyPlus).
