CIBSE NEWS Seeing the light over street lamps


l Exterior illumination goes under the spotlight at the Institute of Education


The Society of Light and Lighting welcomed Dr Mark Rea to the biannual Trotter Paterson Memorial Lecture on 31 January to present his paper: ‘Whatever happened to visual performance?’. The paper looked at the progress of lighting


research in the field of visual performance, a topic that was central to lighting research in the 20th century. In this instance, Dr Rea, director of the Lighting Research Center of Rensselaer Polytechnic Institute in New York, applied the principles of visual performance, such as RVP (relative visual performance), to street lighting. There has been much discussion about streetlights recently in an effort to save energy, and the widely-held assumption that more light reduces the number of road traffic accidents is one that needs to be closely examined. Dr Rea studied a statistical database, which


had been developed in the state of Minnesota to record data on road lighting and traffic accidents, and used regressional models to predict the annual occurrence of accidents in various instances. An analytical approach – including the use of


photometric simulation and RVP – was used to calculate comparative values. The values from both studies were then used to examine the percentage of accidents that could be prevented


Maths and science input required


The Royal Society recently launched its new Vision for Science and Mathematics Education 5-19 project, including a call for views. The society is eager to take


on the ideas of practising professionals in engineering about how and what schools should be teaching, to enable us to meet future challenges. Please make sure the building


with the use of lighting. When the cost of lighting was compared to the costs of accidents that could be avoided with the installation of lighting, a very minimal benefit was indicated. A larger benefit was shown when the lighting


levels were tripled during the four busiest hours of nighttime traffic, when 50% of accidents are expected. In doing this, nominal accidents would be reduced by 2.8%, while operation costs would remain the same. The Trotter Paterson Memorial Lecture was held


in the Institute of Education in London. Dr Mark Rea’s presentation is available to view at www.sll.org.uk The Trotter Paterson Lecture was created in


1951 to commemorate the lives of Alexander Trotter and Sir Clifford Paterson, founding members and past presidents of the Illuminating Engineering Society.

16 March.


Media interns sought


The British Science Association is appealing for CIBSE members to apply for its 2012 Media Fellowship. Scientists, social scientists, engineers and clinicians can experience life in the heart of the newsroom, spending three to eight weeks this summer working with hosts including the BBC, The Guardian and Nature. They will produce accurate, well-informed news about developments in science, and work alongside the UK’s top science editors in the British Science Festival press centre. Successful candidates will


return to work with media confidence, contacts, and first-class communication skills. For eligibility criteria, experiences from past media fellows, and the online application form, go to www. britishscienceassociation.org/ mediafellows Applications close on 16 March.
