Point-by-point modelling in AGi32 for interior, exterior and roadway applications. Issued with the native calculation files, not just a report, so the engineer of record can open the model and check it.
A photometric calculation answers a narrow question precisely: given this room, these surfaces, these luminaires at these positions and this maintenance factor, what illuminance lands on the calculation plane and how evenly. The value of the exercise is that every input is stated. Reflectances, mounting height, light loss factor, calculation grid spacing and the plane height are all declared in the output, so a reviewer can disagree with an assumption rather than with a number they cannot trace.
That matters most where the number carries consequence — a maintained level written into a specification, a uniformity ratio a governing body will check, a spill value a municipality will measure at the property line.
Horizontal and vertical illuminance on any plane, uniformity expressed as min/avg and max/min, glare where the application calls for it, and spill or trespass carried out to the property line. Interior work is calculated against IES RP-7 for industrial spaces and RP-1 for offices. Roadway and site work runs against RP-8 and, in Québec, the MTQ requirements. Sport is calculated to RP-6 and the level of play.
Daylight contribution, emergency egress paths, and vertical illuminance toward camera positions for televised venues are modelled where they apply.
A calculation set with per-space grids and stated average, minimum and uniformity for each; a summary of inputs and the standard each space was run against; pseudocolour or greyscale renderings where a plan view would flatten out something that matters; and the native AGi32 files.
Handing over the native files is deliberate. A PDF is a claim. The model is the evidence, and it lets whoever inherits the project rerun it when the fixture schedule changes during procurement.
Both. The native calculation files are part of every photometric engagement, so your engineer or your contractor can open the model, check the inputs and rerun it if the fixture schedule changes.
Yes, and the standard is stated in the output for each space. IES RP-7, RP-1, RP-8 and RP-6, ASHRAE 90.1, the NECB, the Code de construction du Québec, MTQ and MTO are all routine. Tell me which applies and the calculation is run against it.
A floor plan or site plan, the mounting heights, and the target criteria or the standard the project has to meet. A fixture schedule if one exists. If products are not yet selected, the criteria are set first and the calculation informs the selection rather than the other way round.
Yes. Projects run across Canada and the United States. Documentation is issued in English or French.
A few lines is enough: the space, the levels it has to hit, and when it’s needed. You get a written scope, a fee and a schedule back, normally within two business days.
