In his presidential report delivered at the IESSA AGM on 15 May 2014, outgoing president Greg Marcia said lighting design is a serious profession which has received little recognition largely because there is little in the form of education that can qualify one as a lighting designer.

“There are many points of understanding that will distinguish a designer from a mere operator of computer programmes.” He said this is why the association now offers members and fellows the opportunity to register as “association-recognised ‘competent persons’” in design as well as in other specialist fields such as light measurement and testing.

Marcia said the issues faced by IESSA include poor-quality product and customer dissatisfaction.

“The association’s role must be to share experiences in areas such as end-user education and market surveillance. The focus of the association should be on initiating policies and actions on areas of common interest such as energy efficiency, performance and quality, as well as standardisation and legislation.” To achieve this, members must share knowledge so that best practices can be communicated to stakeholders.

Marcia said IESSA must identify opportunities to convey this knowledge to government agencies so that members could benefit from the process.

IESSA is the national committee of the International Commission on Illumination (CIE) and Marcia said the CIE Tutorial and Expert Symposium on Measurement Uncertainties in Photometry and Radiometry for Industry would be held in Vienna, Austria, between 11 and 12 September this year. The CIE will also host its 28th Session of the CIE in Manchester, UK, on an as-yet unannounced date.

The association’s Development committees were active this year and Marcia commended Phil Hammond and Dereck Currie, the Cape Town and Durban branch committee chairpersons respectively, for “injecting new life into this aspect of the association”. A total of 109 people had attended the various IESSA courses during the year and the association will present a new photometry course hosted at the SABS in Pretoria.

On IESSA’s Technology function, Marcia reported that communication with the association from both members and non-members alike is on the increase.

“Enquiries from organisations including SAFEhouse, the ECB and OUTA show that IESSA is widely recognised in industry,” he said.

The association’s project to separate luminaires from VC8055 has resulted in the compilation of the draft VC 9012. This document was circulated to the relevant working group members for comments. The VC 9012 document gave rise to a need to make allowance for the acceptance of more test reports from different test countries such as the EU.

Marcia said the validation of photometric performance of luminaires claimed to comply with SANS 475 and some covered under the SANS product certification is questioned as no significant validation under the SABS mark scheme has been conducted over many years. If the standard is retained, a complete revision of the photometric data requirements must be formulated.

The new draft document for LED luminaires prepared by a working group resorting under the LED Working Group has passed through the SABS editors, who have asked IESSA’s technical liaison specialist, Connie Jonker, to clear up some queries. This pre-standard, SATS 17576, Marcia expects to be published shortly. The following standards have passed through the SABS editors: SANS 1662

Self ballasted LED tubular lamps, SANS 1664 Semi luminaires for T5 fluorescent lamps and ARP 032 Guidelines for the modification of luminaires for tubular fluorescent lamps.

During the AGM, which held in Johannesburg, Robert Henderson of Eskom was appointed IESSA’s new president at the association’s national AGM held in Johannesburg on 15 May 2014. His appointment takes effect on 1 July this year.
