A second opinion on your AGi32 file
Before a parking-lot photometric goes to a customer or a plan reviewer, send us the AGi32 file. Runnax recomputes every calculation zone from the data inside the file and puts AGi32's numbers and its own side by side. The recomputation takes about 4 seconds. On three real AGi32 parking-lot files, zone averages agreed within 0.06 %. It is free during early access, with no limit on the number of files.
What it reads from the file
- Every luminaire: position, mounting height and aiming.
- The photometric data AGi32 used for each luminaire, so no separate IES files are needed.
- Light loss factors, from lamp lumen depreciation, dirt depreciation and ballast factor.
- Every calculation zone and point: horizontal grids and vertical planes, in feet and foot-candles or metres and lux.
What you get back
- For each zone: AGi32's average, minimum, maximum and ratios next to the recomputed values, and the difference.
- How far individual points differ, as a share of the zone average.
- The file's assumptions in plain words, for example a light loss factor of 1.0.
- A verdict: reproduced, or which zone differs.
A real file: a sports-complex parking lot
15 heads of a 75 W luminaire at 25 ft, 271 points at grade, from a real municipal project in South Dakota.
| AGi32, direct light | Runnax | |
|---|---|---|
| Average | 1.2366 fc | 1.2367 fc |
| Minimum | 0.3946 fc | 0.3949 fc |
| Maximum | 4.7930 fc | 4.7935 fc |
| Largest difference at any point | 0.32 % of the average | |
The file uses a light loss factor of 1.0: no lamp or dirt depreciation. At 0.9 the average would be about 1.11 fc against the 1.0 fc the customer asked for: still a pass, with less room. That is the kind of assumption the check puts in front of you before someone else finds it. Read the case.
Three real parking-lot files
| File | Heads | Calculation zones | Largest zone-average difference |
|---|---|---|---|
| Parking lot A | 48 | 2 horizontal, 2 vertical | 0.06 % |
| Parking lot B (the lot above) | 15 | 1 horizontal, 2 vertical | 0.03 % |
| Parking lot C (metric) | 40 | 3 horizontal, 1 vertical | 0.01 % |
Each was recomputed in about 4 seconds. Project names are withheld. How Runnax is verified.
When it helps
- Before a file goes out: a fast independent check of the numbers and the assumptions, without rebuilding the project in another program.
- When you received a layout: ask your rep or supplier for the AGi32 file and see whether its numbers hold.
- When a reviewer questions the numbers: a second calculation of the same file, zone by zone.
What it is not
- Not a judgement of whether the targets suit the site: it reports the criteria the file's author set. For the IES values, see parking lot lighting requirements.
- Not a compliance statement or a construction approval. The recomputation is direct light only.
How to send a file
- Start a free check with the form: your work email and what you have. You get a reference number and a private status page.
- Email the .AGI file to kyan@runnax.com with the reference in the subject.
- Get the comparison within one business day.
Your file is used for your check only, never shared with another customer, and deleted 30 days after the run. How we use data.
Questions
What does the AGi32 second opinion check?
It recomputes every calculation zone in the file, horizontal and vertical, from the luminaire positions and aiming, the photometric data AGi32 used, the light loss factors and the calculation points stored in the file. You see AGi32's average, minimum, maximum and ratios next to the recomputed ones, zone by zone, plus anything the file assumes that deserves a look, such as a light loss factor of 1.0.
Do I need to send the IES files?
No. The photometric data AGi32 used is read from the .AGI file itself, so the recomputation uses exactly what your calculation used.
How long does it take?
The recomputation takes about 4 seconds per file. During early access a person at Runnax runs it and sends you the comparison within one business day.
How close is it to AGi32?
On three real AGi32 parking-lot files, every zone average agreed within 0.06 %. On the sports-complex lot in our case study, every one of 271 points agreed within 0.32 % of the average.
What if the numbers don't match?
The comparison shows which zone differs and by how much. A difference points to something worth checking in the file before it goes out.
Is it free?
Yes, during early access, and there is no limit on the number of files. Parking lots only for now.
What happens to my file?
It is used for your check only and never shared with another customer. The original file is deleted 30 days after the run.
