3) Fenestration (Table 4)

—

Windows / Doors

Implements SANS 10400‑XA Table 4 per storey. For each floor we compute glazing %, then apply U‑value and SHGC limits.

Total Glazed Area: 0.00 m²

Σ U·A: 0.000

Σ SHGC·A: 0.000

Floor NFA: 0.00 m²

Overall Glazing %: 0.0%

Shading (XA 5.2 compliance)

For overhangs/canopies, projection P must be at least H × multiplier (latitude dependent).

SANS 10400-XA Walls — R & CR Compliance

Calculates total R-value, surface density, and CR-value.

1) Project & Compliance Context

Energy Zone

Include surface resistances R_si/R_se

Metal framing / sheets present?

Thermal break R (if metal present)

Category 1 single-leaf masonry check?

Nominal wall thickness (mm)

2) Wall Assembly (inside → outside)

Layer	t (mm)	k (W/m·K)	ρ (kg/m³)	c (kJ/kg·K)	R (m²·K/W)	mass (kg/m²)	C (kJ/m²·K)

3) Results & Compliance

Total R (incl. Rsi/Rse)

Surface density Σ(ρ·t)

— kg/m²

Areal heat capacity Σ(ρ·t·c)

— kJ/m²·K

CR-value (h)

Classification: —

Zone requirement: —

Result:

Metal framing thermal-break (≥0.20):

Cat 1 single-leaf masonry thickness (≥140 mm):

If metal framing/sheets are present, SANS 10400-XA requires a thermal break with R ≥ 0.2 m²·K/W between metal elements. For Category 1 single-leaf masonry, nominal thickness must be ≥140 mm.
