Shading & carbon — Rio de Janeiro
Rio de Janeiro (BR, 22.9° latitude, 1700 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. Output is an indicative estimate from standard solar geometry — site-specific energy performance also depends on glazing, insulation, occupancy and adjacent shading, and full building-energy verification requires a separate simulation.
132 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 3.3 t of CO₂ avoided in Rio de Janeiro translates into roughly 50 short-haul flights' worth of emissions.
