Quiet rooms can be used for seclusion or de-escalation so design should be flexible to allow for such use. Seclusion rooms are single function rooms with an en-suite designed for low levels of stimuli and to prevent self-harm. Ceiling heights are typically 3m and all luminaries need to be robust, tamperproof and ligature-resistant. The luminaires should be ceiling mounted and switched from outside the room.
|Application||Minimum maintained mean illuminance (lux)||Illuminance uniformity (minimum/average)||Notes|
|Acute mental health facility||300||0.60||The lighting should be designed according to the activity, most areas will be staffed constantly.|
|Psychiatric intensive care units (PICUs)||50-300||0.60||Robust anti-ligature fittings required with manual switches operated by the staff. Levels to be provided by dimming or switching.|
|High dependency rehabilitation units (HDRUs)||50-300||0.60||HDRUs can be categorised as low, medium or high risk. See chapter text to determine the specific lighting requirements.|
|Child and adult mental health services (CAMHS)||5-300||0.60||Designer to be mindful that patients could be children or young adults. Different levels required in different areas. Comfortable, low glare, homely but robust schemes are required.|
|Dementia assessment areas||50-300||0.60||Only very low-glare fittings should be used, and luminaires should not be installed in a regular pattern. Design should include for discrete but robust luminaires to give a calming homely feel.|
|Places of safety||5-300||0.60||These spaces are designed to provide a safe and secure environment.|
