Lighting in Design Q3 2021

floors, achieving an aesthetic look as well as the required lux levels for staircases. Exterior lighting With regards to lighting the exterior of the building, RLS supplied: • Shuttle Double: Creates a nuance for the external perimeter lighting of the building, and was used in conjunction with the Shuttle ceiling, which is mounted on the concrete soffits. • Shuttle Ceiling: External perimeter lighting mounted on the concrete soffits to light up the walkways around the building leading to the entrances and stairways. • Geo Bulkhead: General lighting of the internal /external stairwells and substation areas. • Lumina 1500 mm: This luminaire was chosen to light up the side of the building as well as the building’s name. • Lugo: Basement parking and plant room around the Jan Mouton building. Lighting controls Venues such as auditoriums and lecture halls pose a major challenge, not only to the lighting

installation but also to the level of control required. High-quality light is required to maximise the comfort and productivity of the scholars whilst control of the lighting is crucial for the lecturer to truly capitalise on the session. Auditoriums have many uses and one needs to be able to effortlessly adapt the lighting to the use of the environment. Bright focused lighting on the front stage helps visual communication by enhancing facial expressions or reducing light intensity on the front stage to prevent whitewashing on the screen during a presentation or video. The client’s requirement for the ground floor auditorium was to control the room as one entity but also in the same instance as single entities, meaning that it had to be controlled as a left-hand side and a right-hand side of the room. RLS designed the control system using its daliTECH Omega product range. A combination of configurable scene pads for physical interaction and using motion sensors ensured a perfect balance of user control to best suit the task at hand as well as providing energy savings. The system was commissioned according to the client’s requirements for specific scenes, similarly, this was done throughout all the floor levels. Here is an example of one of the scene pad settings which are mounted at the lecturer’s desk. Scenes 1-4 (100%, 75%, 50%, 25%), scenes 5 and 6 as dimming up and down respectively and scene 7 as presentation mode. Presentation mode, for example, turns all downlighters above the lecturer’s desk off to allow for video presentations on the screen and the rest of the luminaires drop down to 25% which provides an adequate light level for note-taking. The first and second-floor auditoriums had the same split room concept as the ground floor, with one key difference; both halves of the rooms also needed to be able to be controlled together, as a single large room. Control protocols each have their owns set of rules, which need to be adhered to for the systems to work. daliTECH Omega is flexible enough to accommodate small and large environments by combining different products. By doing so RLS was able to achieve the same level of operation in the larger auditoriums as described in the context above.
