AGi32: outdoor & roadway

Where AGi32 wins, outdoor calc points, roadway IES validation, and the report formats consultants and SASO ask for on Saudi tenders.

Animated explainer, press play to watch the concepts now; the filmed cut publishes once production wraps.

What you'll walk away with

01

AGi32 is point-by-point, not radiosity.

Direct illumination only, no inter-reflection. For an outdoor parking lot or a roadway, this is exactly what IES RP-8 asks for and exactly what tenders want.

02

Roadway template builds itself.

Pick the road class (M1–M6 per CIE 140), AGi32 lays the calc grid, mounts the poles to spacing, and runs Lav, Lmin/Lav, TI. Saves hours of manual setup.

03

Glare: TI for roads, GR for sports.

Threshold Increment for driver disability glare. Glare Rating for floodlit pitches. AGi32 ships both calculation engines, DIALux ships only one.

04

Export to PDF, not screenshots.

AGi32's PDF reporter generates calc layout, isolines, and summary table on one page. Consultants accept this format. Screenshots come back with revision notes.

Five decisions that ride on AGi32

AGi32 reads CIE / EN 13201 roadway classes natively; treat it accordingly.

Road class is the design contract.

M-class (motorways) computes luminance (L, cd/m²); P-class (pedestrian) and C-class (conflict) compute illuminance (E, lx). Mixing class and metric in the same calc is a common mis-step; AGi32 lets you, the standards don't.

Pole spacing × mounting height is the lever.

Uniformity uses MH (mounting height) and S/MH ratio. Twin-side staggered with S/MH 3.5-4.0 typically hits Uo 0.40 for M-class. Single-side struggles past S/MH 3.0, switch to opposed.

Surface reflectance class (R1-R4, C1-C2) flips luminance results.

R3 (typical asphalt) is the default; R1 (light concrete) gives 1.4× the L for same E. SASO defaults match EN 13201 R3. Spec the R-class in the calc, most calculations leave it default and report unconservative numbers.

TI and SR are the glare metrics.

Standards limit TI (Threshold Increment) ≤ 10-15% and SR (Surround Ratio) ≥ 0.50. Optical control (cutoff / full-cutoff luminaires) drives both. AGi32 reports them in the M-class compliance summary.

Vertical illuminance matters for CCTV.

Face-plane E_v ≥ 10 lx for facial recognition. Top-down lighting fails E_v even at high E_h. For security-critical perimeters, pair pole lighting with low-mounted bollard or façade lighting to fill the vertical plane.
