LIGHTING SLL PRESIDENTIAL ADDRESS
Carrying the torch
The lighting industry cannot stand still if it is to resolve key challenges around energy efficiency and user well-being, according to the new president of the SLL. Jill Entwistle reports

Peter Raynham said there were undoubtedly shortcomings in the industry that would have a bearing on energy consumption, the quality of the lit environment and human well-being. ‘At present lighting is specified
so that it meets a number of light technical targets within the lit environment. In general the lighting system is optimised so that it meets those targets with minimum overall energy consumption,’ Raynham said. ‘The problem is that there is
a disconnect between the light technical targets and the impact on people in the space. This is not due to any deliberate policy, but simply because we do not understand the processes involved in human visual performance.’ This was not to imply that the
values in the SLL Code for Lighting are wrong, said Raynham, who is editor of the Code and co-author of the SLL Handbook. ‘They are tried
he industry still needs to address the ‘disconnect’ between technical targets and
and tested values that have been used for many years and they give results that give satisfactory lighting conditions. However, we do not know enough to say they provide the optimum lighting solution. ‘Given the drive for energy
reduction we cannot sit back and just carry on with the Code values for ever. For this reason there will be significant new advice on the sensible application of lighting targets in the next edition of the Code, due out towards the end of this year.’
Raynham teaches at University College London, chairs the Light and Lighting committee at the British Standards Institution and leads the UK delegation to the European Standards committee for lighting. ‘As someone whose job involves a lot of research work I quite like calls for more research,’ he said, but added there was a danger that when studies were conducted in artificial environments, erroneous or simplistic conclusions were reached. ‘This is not to say that lighting research cannot provide useful insights and help show the way
Awards Lighting industry figures honoured
Bob Venning, former head of lighting at Arup and the last chairman of the CIBSE Lighting Division before it became the SLL, was given The Lighting Award, a recognition of his outstanding work, contribution to the society and to the lighting industry at large. In a citation written by Barrie Wilde, former head of lighting at BDP Lighting, and read by Eric Maddock, formerly of YRM, Venning was described as epitomising the Arup brand, ‘innovation delivered through engineering excellence’. ‘He gives of his knowledge
and experience generously and freely, and unlike some in lighting

design, he gives it openly without any concern of giving “commercial gain”,’ wrote Wilde in his tribute. The President’s Medal was awarded to Ernest Wotton, a founder member of the International Association of Lighting Designers (IALD) and former lighting consultant in Toronto, Canada, where he moved in 1956 to head up a street lighting company. This year’s Leon Gaster award went to Christophe Reinhart and Valerio LoVerso for their paper, A rules of thumb-based design sequence for diffuse daylight. The Walsh Weston award was given to D Miller, A Bierman, MG Figueiro,
ES Schernhammer and MS Rea for ‘Ecological measurements of light exposure, activity and circadian disruption’. Fellowships were awarded to immediate past president Alan Tulla and SLL secretary Liz Peck. The Regional Award went to Andrew Saville for his contribution to the Home Counties North East branch of the SLL. Sponsors in Partnership
certificates were given to representatives of Erco, Holophane Europe, Philips Lighting, Thorn Lighting and Tridonic. The evening was chaired by Kevin Theobald, president-elect of the IALD.

role of the SLL ‘in solving the mounting problems faced by lighting in a world where energy use is being restricted’. ‘Members of the society
collectively are custodians of many thousands of years experience in the field of lighting. This knowledge base is vital to being able to solve the most important problem facing us, which is how to reduce energy consumption while still providing a well-lit environment.’
