Reference project: how we set up a park and green area lighting intervention
The working method applied by the Lumeitalia technical office to a park and green area lighting intervention, stage by stage.

Overview
This piece describes a design method, not a specific site: the values given are setup criteria, not measurements from a built installation. In urban parks light defines the evening usability of public space, but directly affects wildlife, vegetation and the night sky. The aim is to make repeatable the sequence of decisions that takes a park and green area lighting intervention from survey to commissioning.
Applicable standards
The regulatory reference for park and green area lighting is not a single document but a coordinated set of standards covering performance, safety and environmental impact. In design practice the following documents drive the main choices.
EN 13201-2 — P classes for internal paths.
CIE 150 — limitation of obtrusive light from outdoor installations.
regional laws — protection zones and zero ULOR.
Stage 1 — Survey of the existing condition
The survey precedes any solution hypothesis. Real geometry, position and height of existing luminaires, condition of poles and lines, installed power, operating hours and issues reported by the operator are all recorded. The photographic survey documents the initial state and is the basis for the before/after comparison.
In park and green area lighting contexts the survey must include the conditions that constrain the solution: lighting paths without turning the park into an over-lit area and access limitations for future maintenance.
Stage 2 — Requirements and calculation assumptions
Requirements are declared in writing with their reference standard and the rationale for the chosen category. The same note fixes the maintenance factor, the assumed cleaning cycle and the ambient conditions considered. This is the document that makes the design verifiable and that, in a dispute, separates an execution error from a requirement never agreed.
Stage 3 — Solution selection
Selection starts from the photometric distribution suited to the surveyed geometry, then considers environmental compatibility, the control system and maintainability. At least two alternative configurations are assessed with their impact on luminaire count, installed power and maintenance burden: a documented comparison is what makes the final choice defensible.
Stage 4 — Verification and handover
On-site verification follows the protocol agreed in the specification and closes with a report comparing measured values against declared requirements. At handover the updated calculation report, photometric files of the installed luminaires, maintenance plan and control system configuration are transferred. Without this package, later operation starts from scratch.
Performance data from a real intervention can only be shared if measured and authorised by the client: for this reason the method is described here without site figures. Project-specific documentation is available on request from the technical office.
Recurring critical points
The difficulties that most often emerge in park and green area lighting projects are not about product selection, but about defining requirements and verifying results.
Lighting paths without turning the park into an over-lit area.
Reducing impact on insects and nocturnal birdlife.
Keeping perceived safety during low-attendance hours.
Design approach
An orderly method drastically reduces variations during works and disputes at commissioning. Three choices make the difference from the earliest stages.
A lighting hierarchy distinguishing main paths, secondary paths and rest areas.
Spectra and colour temperatures chosen to reduce insect attraction.
Dimming profiles with partial switch-off aligned to opening hours.
Parameters to verify
P class — EN 13201-2 — internal pedestrian paths
Environmental zone — CIE 150 — E1 to E4, sets spill-light limits
ULOR — regional laws — upward flux brought to zero
Time scheduling — management plan — consistent with park usage
Most frequent mistakes
Non-conformities found at commissioning almost always come from three causes: requirements not declared or declared without a reference standard, calculation run on idealised geometry, and an optimistic maintenance factor. All three can be avoided at zero cost during design.
Geometric, electrical and photographic survey of the existing condition
Requirements declared in writing with reference standard
Maintenance factor and cleaning cycle made explicit
At least two alternative configurations documented
A park and green area lighting project holds up over time when requirements are declared, the calculation reproduces real conditions and on-site verification follows an agreed protocol. Component selection matters, but comes later: without measurable requirements even the best product delivers a result that cannot be demonstrated. Centro Studi Lumeitalia makes its technical office available to review requirements and design checks.

Domande frequenti
Does more light make a park safer?+
Not automatically: uniformity, face recognition and the absence of deep shadow pockets matter more than the average level.
How is wildlife impact reduced?+
By limiting upward and sideways spill, choosing spectra with a lower blue component, and dimming or switching off where no surveillance is needed.
Where should a park and green area lighting project start?+
From a written definition of performance requirements and verification conditions: this step drives every later choice and makes the result either disputable or defensible at commissioning.
Which documents should be requested from the supplier?+
Photometric files of the proposed luminaires, declaration of conformity, lifetime data declared per IES LM-80 with its conditions, the maintenance schedule and warranty terms.
