American standards, Eastern time, billed in USD.

IES RP-7, RP-1, RP-8 and RP-6 are the practice's working standards and always have been. Calculations are issued in footcandles, the energy code is established per state before modelling begins, and the deliverable goes to your engineer of record to stamp.

02 — Controls design

Control documentation

Control documentation is where lighting projects most often come apart on site. The deliverable is a riser, a device and group schedule, and a written sequence of operations — enough for a contractor to wire and commission the system without interpreting intent.

Addressing

Groups and scenes

Each luminaire is addressed and assigned to a group before installation, so zones match the photometric model rather than whatever the circuiting happened to allow.

Sequence

Written setpoints

Occupancy timeouts, dimmed levels, daylight setpoints and emergency behaviour are stated as values, not as intent — which is what makes commissioning verifiable.

Integration

Handover to the BMS

Where lighting reports to a building management system, the points list and gateway requirements are specified alongside the riser so the two trades are working from one document.

03 — Sectors

Industrial, commercial, exterior and sport

The core of the practice is industrial and commercial. The remainder is adjacent work the same modelling and specification process covers.

Core

Industrial

High-bay and low-bay design for spaces where maintained levels, uniformity and glare are a safety and productivity question, and where controls have to hold up against dust, mounting height and shift schedules. Classified areas are part of that work: Class I and Class II, Division 1 and 2, with explosion-proof and dust-ignition-proof luminaires selected on temperature code and gas group as well as on photometry.

Warehouse & distributionManufacturingCold storageHeavy industryYards & laydownClass I / II · Div 1 / 2Explosion-proofAircraft hangars
Core

Commercial

Offices, institutional and retail interiors where the specification has to satisfy an energy code, a brand standard and a fit-out schedule at once, with control strategies occupants will leave in place.

Office & workplaceRetailQSR & drive-thruSchools — IES RP-3InstitutionalHealthcareHospitalityMulti-tenant
Also

Exterior & public

Site, parking and roadway illumination modelled to RP-8 and ministry standards, including submission packages for public authorities and federal facilities, where documentation is reviewed as closely as the design.

Parking & siteRoadway — MTQ / MTOMunicipalFederal facilities
Specialist

Sports lighting

Indoor and outdoor sport designed to the level of play — maintained horizontal and vertical illuminance, uniformity gradients and glare rating to IES RP-6 and the governing body's standard. Televised venues add vertical illuminance toward each camera position and flicker performance that holds up under slow-motion capture.

04 — Process

How a project runs

01

Scope

A call and a review of the drawings, to establish the applicable standard, the spaces in play, and what gets handed over. A written scope, fee and schedule are issued before work starts.

02

Model

Point-by-point modelling in AGi32 against the target criteria — illuminance, uniformity, glare, and where applicable RP-8, MTQ or MTO compliance. Options are compared on their calculated results.

03

Specify

Product-neutral fixture and control specifications, photometric acceptance criteria, and sequence-of-operations documentation, issued in tender-ready format in English or French.

04

Hand off

Calculation files, the specification package, and a review session with your engineer or contractor. Questions on the issued documents during the bid period are covered by the engagement.

Fixed-scope project

A defined deliverable at a fixed fee — a photometric package, a controls design, a feasibility report. Most engagements run this way.

Monthly retainer

Standing capacity for firms with recurring lighting work: a block of hours against calculations, specifications and submittal review.

Review & second opinion

Independent review of another party's calculations, submittals or substitution requests prior to sign-off. Short turnaround, written findings.

Highway LED for a ministry submission

An early LED highway corridor on Autoroute 40 in Trois-Rivières, at a point when LED was not yet established for highway application in Québec and no reference design existed to work from. Pavement classification, veiling luminance ratio, luminaire distribution and pole spacing were established against IES RP-8 from the standard up. Approved by MTQ engineers, and the approach was later applied by the ministry to Route 335 on the Autoroute 19 extension. Work predates the practice, carried out at a prior employer; electrical design and seal theirs.

06 — Calculation output

What the deliverable looks like

Every engagement is issued with the calculation set behind it, not just a summary. These are AGi32 outputs from issued projects, reproduced without client identifiers.

Field, diamond and aquatic area on a single Florida high-school site, calculated together, with per-luminaire aiming from 800 W heads at 15° and 35°. Spill outside the fields of play is part of the same model.

Credentials and standards

Certification · Since 2018

Lighting Certified (LC)

NCQLP — National Council on Qualifications for the Lighting Professions. The examination covers photometrics, energy, controls and visual comfort, and is the principal recognized credential in the field.

Professional membership

IES member

Illuminating Engineering Society. Recommended practice is tracked as it is revised — RP-7 for industrial, RP-1 for office, RP-8 for roadway, RP-6 for sport.

Design basis · Per project

Codes & standards

IES recommended practice, ASHRAE 90.1, NECB and the Code de construction du Québec, MTQ and MTO. Each calculation set states the standard it was run against, so the basis of design can be checked by the engineer of record or the reviewing authority.

Justin Grenier, LC
Principal · Lighting Certified since 2018 · IES member

Twelve years in photometric design, controls and lighting economics across industrial, commercial, institutional, broadcast and roadway work — including early LED highway photometrics approved by MTQ and subsequently reused by the ministry on another corridor. Calculations and specifications issued by the practice are produced by the principal, not subcontracted.
