Courtyards and external spaces offer prisoners a space to exercise outdoors, helping reduce violent tendencies and improving mental wellbeing.

Best Practice Advice
Weather Proof Lighting
External custodial lighting can be fully exposed to the elements, making high IP rated luminaires essential. It is therefore particularly important that lighting is especially robust and requires little in the way of maintenance.
To ensure longevity, and to minimise costs, the paint finishes of luminaires should be highly resistant to degradation.
Rising To The Challenge
Outdoor spaces pose a unique security challenge to correctional facilities. The perimeter walls have to ensure that prisoners stay inside their designated areas and stop “contraband” coming in. With this in mind, various standards dictate specific lighting levels, see technical support.
LEDs with specifically designed optics can vastly reduce energy usage as, for example, lighting with discharge lamps in a floodlight can be very inefficient.
Visitor Car Parks
The lighting should provide basic levels of visibility and, ideally, luminaires should be positioned over and between parked cars to eliminate potential hiding places.
As with any exterior lighting installation, it is important to minimise upward and spill light to prevent light pollution and to ensure it does not cause a nuisance to neighbours.
Different standards may be referenced dependent on the precise nature of the approach to the building. These include BS EN 12464-2:2014 for general outdoor areas including car park spaces. The Estates Directorate Technical Standard STD/E/SPEC/018 provides specific guidance for external lighting within a prison’s perimeter fencing, which varies dependent on the category of the prison (A-D).
