Estimates based on the manufacturer’s declaration, available test reports and HES Group technical literature. The hemp-lime wall area is estimated from the home’s floor area using a geometric model (perimeter, storeys, floor height, openings). CO₂ is calculated at 50 kg/m³, a factor from HES Group’s LCA estimate. This is not a complete building LCA. Indicative values —
