The BEKA SOLAR area solar lighting solution at Hermanus Harbour.

The lighting solution consisted of the BEKA SOLAR, which was chosen for its high-quality materials – a criterion which was especially impor- tant due to the high-corrosive environment in which the luminaires are installed – and its cost-effectiveness. Since it would have been a challenge to get power to site, a solar lighting solution just made sense! BEKA Schréder’s LED solar lighting solution, the BEKA SOLAR, has been installed along a side road that leads through the industrial park towards the harbour. Combined with the ZIYA-E luminaire, the BEKA SOLAR provides a reliable lighting solu-

SHEDDING LIGHT WITH PHILIP HAMMOND Considerations for lighting design for offices O h, my word, where does time go? It is August already and I still have so much to do and achieve this year. Do you feel the same? It has not been the easiest of times as we remain in the grip of the pandemic, but the good news is that by focusing on the positives, some amazing oppor- tunities appear. Keep focused, stay positive, do not be distracted by negative conversations and most of all Stay Safe. In last month’s column, I mentioned a number of aspects of lighting design that were only touched on. This month I will focus on only a couple of those important facets of lighting design to encourage im- proved lighting design in office spaces. Let me start by saying that there are many misun- derstandings about the application of the most com- mon South African National Standards. The stand- ards primarily impact the horizontal measurements on the task area. The biggest problem that I find is understanding what represents the task area, or rather, the primary task area. It is so important to fully understand this because the standards only refer to task area in the tables. The tables do not refer to secondary or move- ment areas. But here it is. Think about your own office task area. Do you include your credenza, your extra meet- ing table, and chairs? No. The primary task area is where you do 95% of your work. When experts from around the world have analysed the workplaces, the primary task area has been found to be 0.5m² to 1m². That means that it is the only part that should be lit to the levels stated in the tables in the stand- ards. The remainder of the wider task area should be lit to about 60% of the primary task are illuminance level. Then, once away from the desk, the level can be 20% of the primary task area but not less that 100 lux which is needed to light the movement area/ walkways within the office and pause areas. Remember that we are living in the time of a ma- jor pandemic in the world. Finally, I will briefly touch on the need to include measures to comply with the protocols for workplaces. This will include having to reposition workstations to ensure that social distanc- ing is applied which will include safe personal space. This measure can be in the form of taped or painted markings on tiled floors or tape carpets or inlaid different carpet to designate safe personal space. Where possible, single direction routes around the office, or where only one passageway is in use, create bi-directional routes. For more detail, here is a link to an article that I wrote for Lighting in Design, published by Crown Publications; https://www.bhaschooloflighting.co.za/ illuminating-the-post-pandemic-office-featured-in- crown-publications-lighting-in-design-magazine I will continue taking you on a journey through the considerations when doing a lighting design for offices. The main topic will be Equivalent Visual Ef- ficiency (EVE).
