Layout, luminaire selection and design intent for interior spaces — from high-bay industrial through office, institutional and retail. Criteria are set and documented before any product is chosen.
The usual order on a lighting project is backwards. A rep offers a free layout, the layout arrives with a fixture already in it, and the basis of design is set by whoever moved first. The criteria are then reverse-engineered to match the product that was always going to be specified.
Running it the other way costs a fee and saves the difference several times over. Target levels, uniformity, glare limits and power density are established against the applicable standard and written down. Product selection then has something to satisfy, and substitution requests during procurement have something to be measured against.
Mounting height, dust and contaminant loading, shift schedules and rack layouts all change what a space needs and what will survive in it. High-bay design is largely a question of maintained level, uniformity across aisles, and glare from the operator's actual sightline rather than from a plan view.
Cold storage, hazardous locations, yards and laydown areas each carry their own constraints, and they belong in the criteria rather than in a change order.
Class I and Class II, Division 1 and 2 areas — and the Zone equivalents where a project uses them — change the selection problem before photometry is even considered. The luminaire has to carry the right gas group and temperature code for the material present, in an enclosure rated for the environment, and the list of products that qualify is short.
Then the optics fight back. Explosion-proof and dust-ignition-proof fittings run lower lumen packages than their ordinary-location equivalents, guards and glass globes absorb output and redistribute it, and mounting positions are often fixed by the process rather than by the lighting. Hitting an RP-7 maintained level in a classified area means calculating with photometric files that include the guard, not the bare optic, and proving the result rather than assuming a fixture count.
Interiors usually have to satisfy an energy code, a brand standard and a fit-out schedule simultaneously, and those three pull in different directions. The design work is largely in finding the arrangement that satisfies all three without any of them being quietly dropped.
Control strategy is part of the design, not an afterthought, because a strategy occupants find irritating will be disabled within a month and the energy model behind it becomes fiction.
The practice takes a fee and carries no product lines and no manufacturer commissions. That means the specification can be product-neutral and a substitution can be assessed on whether it meets the stated criteria, rather than on whose product it is.
Yes. Reviewing another party's layout, calculations or submittals before sign-off is a common short engagement, and it often catches a problem while it is still cheap to fix.
Layouts, luminaire schedules, mounting details and the design basis narrative are issued in tender-ready format, in English or French. Your engineer of record reviews and stamps.
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.
