RMIT UNIVERTITY - Building 51, 80 Victoria Street, Carlton
As part of reducing the environmental impact of their facilities, a major lighting upgrade was completed at one of many RMIT’s city buildings. The upgrade was carried out on one of the older buildings, with outdated lighting technologies and no form of automatic lighting controls.
Features of Sustainable Lighting
- The fittings installed are T5 fluorescents managed by a lighting control system that maximises natural lighting (motion and day light sensors) and sets optimal Lux levels for overhead lighting at 320 Lux. Fittings were complete with DSI dimmable electronic ballasts and ULB diffusers
- Incorporated in these fittings were Managed Lighting System detectors which automatically turned the lights on & off based on occupancy as well as regulating the light levels in response to the natural daylight levels
- The unique daylight dimming enables the lighting to react to changes in ambient lighting levels contributing to significant reductions in base load
- Approximately every two luminaires in the general office space have a sensor which enables individual comfort control and best practice zoning
- The motion sensors were provided to the luminaire manufacturer, and were built into the face of selected luminaires (approximately one in two), and internally wired to the ballasts
The resultant benefits were substantial improvements to aesthetic and visual comfort levels for staff and students as well as significant reductions in overall energy consumption and greenhouse gas emissions. Light levels have increased; uniformity has improved adding to overall increased visual comfort levels.
