Ene03 - External lighting – Above Green

(1 credit available)

Aim

To recognise and encourage the specification of energy efficient light fittings for external areas of the development.

Assessment criteria

The following is required to demonstrate compliance:

One credit

The building has been designed to operate without the need for external lighting (which includes on the building, signs and at entrances).

OR alternatively, where the building does have external lighting, one credit can be awarded as follows:

The average initial luminous efficacy of the external light fittings within the construction zone is not less than 60 luminaire lumens per circuit Watt.

All external light fittings are automatically controlled for prevention of operation during daylight hours and presence detection in areas of intermittent pedestrian traffic.

Checklists and tables

None.

Compliance notes

Ref	Terms	Description
Shell and core (non-residential and residential institutions only)
CN1	Applicable assessment criteria	Both options: All criteria relevant to the building type and function apply. Refer to Appendix D – Shell and core project assessments for a more detailed description of the shell and core assessment options.
Residential - Partially fitted and fully fitted
CN2	Applicable assessment criteria - Single and multiple dwellings	Both options: All criteria relevant to the building type and function apply. Refer to Appendix E – Applicability of BREEAM New Construction to single and multiple dwellings, partially and fully fitted for a more detailed description of residential assessment options.
General
CN3	Single building assessments on larger developments or campuses and extensions to existing buildings	Where the building being assessed forms part of a larger development (or is an extension to an existing building) containing common areas and other buildings, the scope of the external lighting criteria applies only to external new and existing lighting within the construction zone of the assessed building.
CN3.1	Temporary lighting, decorative lighting and floodlighting	Temporary lighting such as theatrical, stage or local display installations, where specified, can be excluded from assessment under this issue. Decorative lighting, security lighting and floodlighting must, however, not be exempt from the assessment criteria.

Methodology

Average initial luminous efficacy of the external light fittings

The individual luminous fluxes of all luminaires within the construction zone are summed (in lumens), then divided by the total circuit Watts for all the luminaires.

For lamps other than LED lamps, the luminous flux of a luminaire using those lamps can be determined by multiplying the sum of the luminous fluxes produced by all the lamps in the luminaire by the light output ratio of the luminaire (as confirmed by the luminaire manufacturer).

Note: LED lamps are typically integral to the luminaire (LED luminaires). As such, the manufacturers' literature will encompass both lamp and luminaire as a whole.
