Outsourced lighting calculations with DIALux evo — interior, exterior and emergency lighting, compliant with BS EN 12464 and CIBSE guidance.
We produce professional lighting calculations using DIALux evo — the industry-standard software for lighting design — for contractors and consultancies that need compliant calculations without an in-house lighting designer. A well-executed lighting design is both a safety requirement and a compliance obligation, and our packs provide the engineering evidence for both.
For interior spaces we calculate maintained illuminance, uniformity and glare ratings (UGR) against the task requirements of BS EN 12464-1 and CIBSE guidance — from offices and retail to rail station platforms, airport terminals, industrial units and plant rooms. For external areas — car parks, roads, walkways and airside facilities — we design to BS EN 12464-2 and BS EN 13201, balancing compliance with energy performance (lighting power density).
We produce emergency lighting calculations and coverage analysis to BS 5266: escape route and open-area (anti-panic) illuminance, luminaire spacing verification, and marked-up layouts showing emergency luminaire positions — the documentation building control and fire strategy reviews expect to see.
Lighting circuits still need compliant power design — see our ProDesign cable calculation service for the distribution side of the same project.
Common questions about outsourcing DIALux lighting calculations.
Floor plans (DWG or PDF), a room schedule with ceiling heights and surface finishes if available, the target lux levels or the applicable standard, and any preferred luminaire ranges. From that we build the model and return the calculation pack.
Yes. DIALux evo works with photometric data from virtually every manufacturer, so we can design around your wholesaler's ranges, a client-specified schedule, or propose suitable products if you have no preference.
Yes. We produce emergency lighting calculations and coverage analysis to BS 5266, including escape route and open-area illuminance checks and luminaire spacing verification, suitable for building control and fire strategy submissions.
Yes. Each pack includes the calculation results, luminaire schedule, layout drawings and 3D visualisation outputs, demonstrating compliance with BS EN 12464 and CIBSE guidance in a format ready for design submissions.
