Inputs

Schedule spaces

Add one row for each relevant space, item, zone, document, or measurement set.

Row 1

Space name Enter the project label, note, or reference used for this calculation. Area m2 Enter a numeric project value in m2 at or above 0.01. Task plane Choose the option that best matches the project condition. Maintained target lux Enter a numeric project value in lux at or above 0.01. Maintenance factor Enter a numeric project value between 0.01 and 1. Utilisation factor Enter a numeric project value between 0.01 and 1.

Row 2

Space count --

Total area -- m2

Area-weighted target -- lux

Total required initial lumens -- lm

Schedule status --

Important notes

The schedule records maintained-illuminance assumptions for review and handoff; it is not certification.
AS/NZS 1680, NCC context, task classification, glare, uniformity, and emergency scope require professional review.

Formulas

\(\displaystyle \Phi_{\mathrm{initial,row}} = \frac{E_{\mathrm{maintained}} \times A}{UF \times MF}\)
\(\displaystyle E_{\mathrm{weighted}} = \frac{\sum E_i A_i}{\sum A_i}\)

Build a maintained-illuminance schedule from space, task plane, target, UF, and MF assumptions.

Maintained Illuminance Schedule Builder is a planning aid. Keep the target source, product data, measurement method, and project assumptions with the result. Confirm compliance, installation, certification, and safety decisions with the responsible professional.
