Ensure that lighting design will improve energy and sustainability objectives of the building, a centralised lighting control system should be specified to allow easy monitoring; or automate the system with a proper control strategy.
Ensure the following:
(a) The lighting control is readily accessible
(b) Lamp efficacies and ballast energy performance should meet the latest minimal energy performance standard (MEPS)
(c) Lighting power density is calculated for the building and, that it meets the lighting power budget in SS 530 (see also ANSI/ASHRAE/IES standard 90.1)
Calculate daylighting in accordance with BS ISO 10916 or equivalent.
Adopt the recommended illumination levels for office areas and task activities in accordance with SS 514, CSA Z412-2000 (R2016), ISO 8995-1 or equivalent.
Adopt the specifications for luminaires, for general requirements and tests in accordance with SS IEC 60598-1 or equivalent.
Note that accordance with ISO 8995-1, SS 531-1 or equivalent, maintained illuminance depends on the maintenance characteristics of the lamp, the luminaire, the environment and maintenance programme.
Separate control display and ornamental lighting.
Routine checking should be carried out of adequate lighting levels and maintain adequate lux for appropriate activities in accordance with users’ needs and statutory guidelines in accordance with CSA Z412-2000 (R2016), ISO 8995-1, SS 531-1, SS 514 or equivalent.
Lamp surfaces should be dusted off and cleaned.
Regular inspection of light fittings should be carried out and replaced if burnt-out. Consider group re-lamping if lamps in the same batch are failing.
Routine check on transformers and drivers of luminaires should be carried out.
Exterior lights for corrosion, torn cables, compromised watertight seals and discolouration should be checked, remedial action should be taken where needed.
