Sample result: a past project check
The customer sent the AGi32 file of a parking lot: 15 poles at 25 ft, 75 W LED area lights. Runnax Engine read the fixtures, aiming and calculation points straight from the file and recalculated every point on its own, in about 4 seconds.
1 · Zone by zone
| Zone | AGi32 avg / min | Runnax avg / min | Difference | Your target | Meets it |
|---|---|---|---|---|---|
| Parking area, horizontal at grade (271 points) | 1.237 / 0.395 fc | 1.237 / 0.395 fc | 0.01 % | Eavg ≥ 1.0 fc, Avg:Min ≤ 3.3 | Yes |
| Vertical at 5 ft, facing 71° (495 points) | 0.553 / 0.000 fc | 0.553 / 0.000 fc | 0.03 % | none given | – |
| Vertical at 5 ft, facing 251° (495 points) | 0.485 / 0.000 fc | 0.485 / 0.000 fc | 0.03 % | none given | – |
Foot-candles, direct light. Point by point, the largest difference on the parking area is 0.3 % of its average. The vertical grids in this file run into the corners of the lot, which is why their minimum is 0.
2 · What the file assumes
Light loss factor 1.0. No lamp or dirt depreciation, so these are initial levels. At a typical 0.9 the average drops to about 1.11 fc: still above your 1.0 fc, with less room. Some reviewers ask for the factor to be stated on the plan.
3 · Can fewer poles do it?
Not run for this lot. Your criteria are average-based (Eavg, Avg:Min), and the layout search currently takes minimum-based targets; the lot is also wider than the single-aisle arrays it searches today. When a lighter layout can be searched and passes, this section shows it next to yours: pole count, mounting height, the same zone table and the pole positions, so you can rebuild it in AGi32. When none passes, it says so.
4 · Inputs on record
- File: the .AGI you emailed (15 luminaires, 3 calculation zones)
- Fixtures: 75 W LED area light, two optics, photometry as stored in your file
- Mounting: 25 ft, 3 ft arm, tilt 0–10° as in your file
- Light loss factor: 1.0, from your file
- Targets: Eavg ≥ 1.0 fc and Avg:Min ≤ 3.3, from your request
- Method: point-by-point direct illuminance, the same basis as AGi32's exterior calculation
5 · Check it yourself in AGi32
- Open your file, run the calculation, and compare each zone's statistics with the AGi32 column above.
- To see the light loss effect, set the factor to 0.9 for all luminaires and recalculate.
- The point-by-point values from both calculations come with the result as CSV.
