Stage 11

Lighting

Record connected lighting power and the net floor area used to calculate project lighting performance.

What you will learn

  • Understand the link between connected load and area.
  • Keep the lighting area aligned with project NFA.
  • Document the source of luminaire quantities and wattages.

Prepare before you start

  • Lighting layout or schedule
  • Luminaire quantities and connected wattages
  • Confirmed project net floor area

Step by step

Complete this stage

1

Confirm the area basis

Review the project NFA that is carried into the lighting calculation.

2

Enter connected load

Use coordinated luminaire quantities and wattages rather than an allowance with no documented basis.

3

Review calculated density

Use the displayed result to identify unexpected loads or area mismatches.

4

Update after design revisions

Repeat the check when luminaire selections, quantities or floor areas change.

Quality check

  • NFA agrees with the project setup.
  • Emergency, decorative or external loads are treated consistently with the project method.
  • The connected load can be traced to a schedule or calculation.

Use this guide with the current project documents, official standards available to your team and the review required for your professional role.
