42 LIGHTING MAGAZINE | April/May 2016 April/May 2016 | LIGHTING MAGAZINE 43 ARCHITECTURAL SCIENCE ASSOCIATION 50TH CONFERENCE Fifty years later: Revisiting the role of architectural science in design and practice The 50th International Conference of the Architectural Science Association (ASA) will be held at the University of Adelaide from 7-9 December 2016. It was in Adelaide that the first meeting of the Association took place in 1963. Architectural science and design researchers, educators, students and practitioners are invited to exchange ideas that will contribute to the betterment of our environment. All papers will be double, blind refereed. Papers will address the following challenges and opportunities arising from contemporary issues such as: z what are the contemporary issues that architectural science researchers and educators should focus on? z what are the real impacts of applying the knowledge explored in architectural science as implemented in various design advice, building codes and standards, on the quality of our built environment? z how should architectural science researchers and educators respond to increased urbanisation, higher density living, and increased awareness of sustainable living? Workshop Expressions of Interest: If there is sufficient interest, the conference will also feature a series of workshops, including IEQ monitoring, building performance simulation software packages, etc. Please enter your preference on the workshops at https:// www.surveymonkey.com/r/ASA2016- workshop-survey For more information about the conference, including key dates, program, venue and accommodation please visit: http://www.architecture.adelaide.edu.au/ asa2016/ IES UPDATES+POSTS 4TH CIE EXPERT SYMPOSIUM ON COLOUR AND VISUAL APPEARANCE This will be held on 6th and 7th September 2016, in Prague, Czech Republic, preceded on 5th September by a CIE Tutorial on Visual Appearance Fundamentals and Measurement. The symposium is jointly run CIE by Divisions 1 and 2 and will be of interest to those concerned with aspects of the perception and measurement of visual appearance and measurement of the bidirectional reflection and transmission distribution functions of modern materials. It will provide the attendees the opportunity to: z present the state of the art in our understanding of the perception of the visual attributes, such as colour, texture, translucency and gloss, z present the latest achievements in the fields of novel measurement methodologies such as BRDF, BTDF, BSSRDF and others and z explore the possible applications of visual appearance knowledge and novel measurement methodologies for the design and characterisation of modern optical surfaces. Visual assessment of the appearance of objects and materials is a complicated process. It involves aspects such as: the object and its optical characteristics; the position, size, shape and spectrum of the light source; the nature of the visual field surrounding the object; and the observer’s visual system with its amazing complexity. Research areas have been formed devoted to the four visual attributes: colour, gloss, texture and translucency. The development of new visual appearance effects, such as goniochromatism and graininess, have required progress and evolution in the quantification of visual appearance and corresponding measurement setups. The outcome of research in this area is significant for industrial sectors where the measurement of visual appearance is important and for manufacturers of measurement equipment. The tutorial on visual appearance fundamentals and measurement will be devoted to the bidirectional reflectance distribution function (BRDF) and BTDF (transmission) of surfaces, a field in which there has been recent progress at both the metrological and instrumental level. There are now instruments marketed primarily for this purpose either in a number of fixed measurement geometries (called multi-angle spectrophotometers) or with the possibility to scan across arbitrary geometries using rotating stages (goniospectrophotometers). However, performing BRDF and BTDF measurements is not trivial and can require adapting the available instrumentation for measurement of the specific quantity. This tutorial will present appropriate ways to make such adaptations. Examples, including the measurement of near-lambertian, glossy, goniochromatic, sparkling and translucent surfaces, will be used to demonstrate instrumental adaptations and case studies with a set of typical samples will be proposed.

CORRECTION Lighting apologises for an editing error in the report on the IESANZ Luminaire Design Awards published on page 63 of the December 2015/January 2016 edition. The error resulted in the wrong company being attributed to the Darkon Tube luminaire. Darkon is the designer and manufacturer of the Tube. – Warren Julian AWARD OF COMMENDATION TO DARKON FOR THE TUBE Design statement The Tube profile has been designed to achieve homogenous illumination via a round opal acrylic lens, using a single row LED light source, combining with high IP-rated endcaps to eliminate any ingress of dust, bugs and water. Judges’ comments In what is already a flooded market of high powered LED extrusion luminaires the Tube is a breath of fresh air offering something completely different to the rest of the pack. The use of a single LED board to create an up/down distribution really sets it apart from the rest of the field. The clever lens design addresses the sometimes complicated installation of high powered LED extrusion. The range of different IP ratings available, all with the same aesthetic look is a nice touch. NSW CHAPTER MEETING NOVEMBER 2015 The NSW Chapter hosted a “Technical” Meeting was by at the Cricketers Arms Hotel, in Surry Hills. Being the final meeting of the year, the emphasis was on the social nature of the evening. The educational institutions and IES made presentations, clarifying the options available future lighting-students, as well as the educational requirements for the various grades of technical membership. Certificates were presented to upgraded members, Bryan Leibowitz (FIES) and Ales Vasenda (MIES), by the Chapter Chairperson, Tim Shotbolt.
