Layout Designer

Build photometric lighting layouts — import floor plans, place fixtures, draw calculation grids, and share results.

  1. Create a new layout

    Start a fresh layout from scratch in the Layout Designer and give it a name you'll recognise later.

  6. Add and configure a calculation grid

    Draw a calculation area over your design so OpenLumen can compute illuminance values, uniformity, and average / min / max light levels.

  8. Check energy-code (LPD) compliance

    Read the watts-per-area figure for an area and see how it stacks up against ASHRAE 90.1 and IECC lighting power density limits.

  11. Read the pole map symbols

    Understand the pole mini-view glyph — a compact top-down map that shows each head's arm, the way it aims, and its fixture type, all from above.
