ABSTRACT
When submitting a design proposal to clients, it will usually be necessary to supply information on the following topics:
— the design specification, i.e. the type of lighting system, the design maintained illuminance, illuminance variation, the maintenance programme, the glare index, the lamp colour properties, the wall-to-task illuminance ratio, the ceiling-totask illuminance ratio, and other criteria as applicable
— the equipment to be used, e.g. lamps, luminaires, control systems
— the layout of the equipment
— the costs, in an appropriate form
— the lighting conditions that will be achieved if the maintenance programme is implemented
— the calculation and measurement tolerances (see CD) that apply to these values
— the power density and operating efficacy of the installation
— all assumptions made in the design.
