Lighting — Single Occupancy

Enter your one occupancy type, project NFA (auto from Basics), and add internal/external fixtures. The tool aggregates connected load and checks LPD ≤ Table 12 (SANS 10400‑XA 6.2). In H3/H4, using LED/CFL is deemed compliant. Sensors required in all other occupancies with coverage ≤ 100 m² per sensor.

Project NFA (m²)

Auto-summed from Basics; can be overridden.

# Sensors (required unless H3/H4)

Area per sensor must be ≤ 100 m².

Internal W: 0 W

External W: 0 W

Total W: 0 W
