Shading & carbon — Gothenburg
Gothenburg (SE, 57.7° latitude, 990 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.
14 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 0.4 t of CO₂ avoided in Gothenburg translates into roughly 50 short-haul flights' worth of emissions.
