Reducing Energy Use at Bristol University
In a bid to improve lighting levels whilst reducing energy consumption, Steinel’s RS Pro Sensor light fittings have been installed in the corridors of the School for Policy Studies at Bristol University, in line with the university’s Environmental Policy for reducing energy usage.
Established in 1995, the School for Policy Studies is located in a series of four large Victorian villas situated among the main university buildings in the Clifton area of Bristol. The department currently houses 407 students from a wide range of backgrounds, creating a lively and diverse environment for study and research.
The project has involved the replacement of 28W2D luminaires in the corridors of a four storey building with no natural daylight. Because of the lack of natural illumination the lights were previously switched on all day and the diffusers had aged and yellowed, resulting in poor light quality. A need to improve lighting levels, and improve energy efficiency in line with the University of Bristol Environmental Policy for reducing energy usage was identified. An energy efficient light fitting with good light output, and presence detection to ensure the lights operate only when required was needed to meet these requirements.
The Steinel RS Pro Sensor light fitting incorporating an integral microwave presence detector was selected for its good light output and ability to provide accurate and easy adjustment of light levels. The integral sensor enables the RS Pro Sensor to be connected to the existing circuit wiring in one simple operation, without the need to wire separate presence detectors. This resulted in reduction in installation times and costs, in addition to the energy and financial savings that will be enjoyed by the facility.
Steinel’s RS Pro System professional sensor lights provide the last word in energy efficiency and flexibility. The high frequency sensors are invisible from the outside and offer greater precision, reach and speed than infrared sensors in this type of interior fitting. Illumination is automatically switched on and off when required, whilst the ‘Light ON’ duration and twilight threshold can be adjusted to the desired setting.
Feedback from the department has been vey positive, in terms of much improved light quality and performance, as the lights are off when not needed and have a quick response time when someone is detected in the corridor.
