Lighting in Design February-March 2018

at. “The light fitting used is from our Vala range,” explains RLS’s Byron Lottering. “With an LM 6 die cast aluminium and extruded aluminium housing, the fitting is designed to operate a range of LEDs up to 48W.” Mott MacDonald Consulting Engineers Africa, the electrical engineers, worked closely with RLS and GREENInc to take the design and make it work in practice. Flexibility of the lighting solution was very impor- tant for the client. “As it is an open and clean space, the lighting gives the site more versatility.The lights are on day/night switches as well as all being on different circuits, so they can be switched on and off depending on the requirements of the events, and they are all set on a dimmer, which is another advantage,” says Honiball. Eventing options are be- ing explored, such as weddings; Thai Chi classes, star gazing evenings and arts and entertainment. “The control gear used is DALI, which allows for dimming of LEDs,” says Ronald de Lange, electron- ics and automation engineer at RLS. “Currently, it is programmed to be able to dim at four different light levels via four push buttons, yet using DALI allows for future upgrades such as daylight harvest- ing and motion control. DALI also creates potential for connectivity for added flexibility; smart devices can be connected to the system to make lighting control a lot easier.” Maropeng translates as ‘returning to the place of origin’, and with the Human Impact picnic site, all those involved have contributed to creating a space that not only celebrates human achievement in an unpretentious way, but through the design and the technology employed, have achieved the design goals by being almost unobtrusive in their intervention. Having been completed in October 2017, the landscape is still new and will mature over time, with many of the trees and plants needing a few seasons to establish themselves, yet the client is very happy, as is GREENInc. “It came out beautifully,” concludes Honiball.
