Implements SANS 10400‑XA Table 4 per storey. For each floor we compute glazing %, then apply U‑value and SHGC limits. If glazing % ≤ 20% → Any solution.
Total Glazed Area: 0.00 m²
Σ U·A: 0.000
Σ SHGC·A: 0.000
Total Floor Area (NFA): 0.00 m²
Overall Glazing %: 0.0%
Note: Solar SHGC limit depends on shading compliance
South/SE/SW SHGC: Any solution
