HEA 05 - Minimising flicker from lighting systems

Applicability – no occupied spaces - KBCN1551

Principle Where:

• The scope of assessment covers no occupied spaces and,
• There is no valid way to filter credits from that issue,

Credits specifically related to occupied space are not awarded. Outcome The tables below show how this principle applies to affected issues.

• Y means all credits are available (unless the comments state otherwise). Standard filtering rules still apply, so some credits can be filtered out where allowed in the criteria.
• N means all credits in the issue cannot be awarded. These credits are not filtered out.

Emergency lighting - KBCN0185

Maintained systems featuring emergency light fittings which are also used for normal operation, are assessed for this issue. Non-maintained lighting which is only activated in an emergency can be excluded from the assessment. NC / RFO / BIU V6 Ene 17: The aim of these credit(s) is to encourage and recognise energy-efficient fittings. Non-maintained emergency lighting will very rarely be activated and in such extremes the emergency requirements must not be compromised. BIU V6 Hea 05: Flicker is eliminated from maintained systems only.

24-Jan-2024 - Scheme applicability updated to include BIU V6.
