LG22 – Lighting for control rooms (2022)
Control rooms can be complex, having many operators with their often extensive arrangement of screens around them and perhaps large overview screens on walls in front of them. Many rooms operate 24 hours a day, some monitoring and controlling safety-critical operations. For these reasons establishing the geometry between operators, their screens, larger remote room displays, and the lighting and any windows is crucial.

Designing the lighting, daylight admission, sunlight control and lighting control systems requires discussion and cooperation between the lighting designers and others involved in the design of the room. If the power to the normal lighting fails in control rooms, monitoring life- or safety-critical operations normally requires full or partial standby lighting throughout the room. As this will be supplied from UPS and/or standby generators, early discussion with the electrical designers is vital.

Once all building, electrical and display screen/user parameters are established, the design of the lighting, and possibly daylight control, can be carried out. As well as making sure no bright images are visible to the users on any of their screens, the room lighting needs to provide a constant minimum level to ensure the operators remain alert – this is most important during the night shift where there may be an increased risk of operators becoming sleepy if the room lighting is dim.

LG9 – Lighting for communal residential buildings (2022)
This third edition of SLL Lighting Guide 9: Lighting for communal residential buildings, includes detail of new types of multiple-occupancy building, the latest findings on the effect of lighting on wellbeing, and advice on how to minimise obtrusive light from external lighting. All sections have been updated to reflect the switch to LED light sources.

This guide is for the use of anyone involved in specifying luminaires and lighting systems for multi-occupancy residential buildings. It aims to provide practical guidance and demonstrate good practice. Those responsible for communal residential buildings have to consider energy efficiency, safety and security, as well as the welfare of people who live there.

This guide provides practical guidance and demonstrates good practice with recommendations on how to meet statutory requirements while achieving a pleasant ambience for residents in their living areas. Multi-occupancy residential buildings consist of all building types, from rented or private apartments through to student accommodation, social housing, schools, sheltered housing, nursing homes, hospices and many other types.
