2) Orientation

—

Main Building Orientation: —

Determined by the primary façade of the first storey. Fenestration calculations will use storey-specific orientations for accuracy.

Orientation (primary façade)

Choose: North, North-East, East, South-East, South, South–West, West, North-West.

#	Storey	Orientation	Note

3) Shading (Table 3)

—

Shading (XA 5.2 compliance)

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

4) Fenestration (Clause 5.3)

—

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 (Solar): 0.000

Floor NFA: 0.00 m²

Overall Glazing %: 0.0%

5) Rooflights (Clause 5.3.8)

—

Roof lights / skylights — Table 5 compliance

Checks the rooflight‑to‑room floor area ratio and applies Table 5 bands for U and SHGC. If the ratio is < 1.5%, “any solution” applies.

SANS 10400-XA Walls — R & CR Compliance

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

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.
