Flow chart for lighting planning
1. Scope
- What should be evaluated? Electric lighting, emergency lighting, daylight conditions, function and control, maintenance plan, electrical efficiency, etc?
2. Conditions
- Regarding the checking of new installations – which conditions applied in installation planning?
- Evaluation of existing systems?
- Evaluation with or without daylight?
- Are the measured values new values or operational values?
3. Implementation/checks with light measuring
- Illuminance – average value/uniformity for the working area, immediate surrounding area as well as within the peripheral surrounding area.
- Luminaire average luminance.
- Calculate where appropriate, the UGR glare number.
- Luminance conditions in the premises.
- Luminaire screening angle.
- Light source colour reproduction and colour temperature.
- Perform visual evaluation and interview personnel.
- Perform function check.
- Check the calibration, burn-in time and prevailing operating conditions prior to light measurement.
