01 · Establish the brief
Describe users, activities, hours, visual tasks and intended atmosphere. Identify the applicable IES recommended practice, then the jurisdiction and adopted code. A recommended practice, an energy requirement and a client preference have different roles; document each instead of mixing them into one unsupported target.
02 · Set the evaluation criteria
Define what must be evaluated: maintained illumination, distribution, glare, color appearance, controls, access and maintenance. Obtain project-specific numerical criteria from the full applicable guidance. Our application directory links to official IES documents rather than inventing a universal lux table. [1] [2]
04 · Review the experience
Use calculations and mock-ups for different questions. A calculation helps evaluate declared quantities across a grid. A mock-up helps examine material appearance, reflections, interfaces and occupant experience. Document why an option was accepted and what uncertainties remain.
05 · Specify and commission
Write a coordinated specification including photometric configuration, control compatibility, aiming, test documentation and verification procedures. At handover, test scenes and overrides, record settings, and explain maintenance responsibilities. The control practice LP-6 is an official starting point for this part of the work. [5]
