� Internal lighting layouts demonstrating that the maximum candela from internal
luminaires does not exit through any transparent/translucent building surfaces, OR,
that controls have been installed to automatically turn off interior lighting outside
normal occupancy hours with a manual override capability to enable out-of-hours
use;
� External lighting drawings and details of lighting controls and locations of daylight
sensors. Specification and luminaire schedule confirming mounting heights and all
information relating to the aiming of each luminaire;
� Control Strategy confirming which luminaires will be turned off during curfew and
which luminaries will operate at the reduced levels. Specification confirming that
the safety or security lighting used between 23.00 and 07.00 complies with the
lower levels of lighting recommended in IESNA RP-33-99 and IES RP-8; and
� Report detailing the lighting calculations for the external lighting demonstrating
that the required illuminances, both at the site boundary and at the specified
distance beyond, and percentage uplight limits have been met.
� Revised Design submission to reflect any changes in the constructed building;
� As built electrical specifications and drawings confirming external lighting
(including security lighting) and controls; and
� Photographic evidence confirming:
� External lighting and controls; and
� Cutoff luminaires, if provided, have been angled to limit spill light to
potentially obtrusive directions.
Calculations must consider, at a minimum, lights such as: security, feature, foyer,
display, landscape, car park lighting, external signage and advertising, 24 hour office
lighting, and any light visible through skylights and atria.
High structure aircraft hazard lights are excluded from the calculations.
Any floodlighting used, for example for school sports grounds, for a limited amount of
time in the evening can also be excluded from the calculations.
Safety lighting – Lighting provided to enhance occupant safety, often used outside of
daylight hours to provide sufficient light levels to enable safe use of areas such as main
entrances, pathways, steps and car parks.
Security lighting - Lighting provided to deter intruders and protect property.
