6000 TRIDONIC DALI LED DRIVERS INSTALLED AT AL MAJDOUL TOWER

T agged as the eighth tallest twisting tower in the world and the first in Riyadh, the Al Majdoul Office Tower – situated in the centre of Riyadh’s new downtown area – is an iconic sight. Its unique helix-shaped design is supported by a simple square floor plate of post-tensioned slab that rotates 2.5 degrees at each of its 55 floors to allow sunlight in at strategic hours. Internal support is done through a single ring of structural columns and the circular service core. It stands at 244.55 m, and its total size is 74 000 m 2 . The Al Majdoul Tower’s futuristic design also features an extensively landscaped entrance plaza and 30 zoned elevator systems specified to ensure no delay in transiting from floor to floor.

after thorough reviews and testing of the DALI light- ing system solutions of several reputable DALI Driv- er manufacturers, the consultants decided to go for Tridonic, not only because the company is renowned for adhering to strict manufacturing quality stand- ards, but also because of good lead time, price and service The Tridonic LED technology solution Tridonic’s versatile, easy-to-install, and reliable DALI LED Driver technology was used for the spotlights in the building lobby and the hallways, the cove lighting throughout the whole building, and in all the elevator lights. Around 6000 pieces of LED Drivers were in- stalled all throughout the building. Total energy sav-

ings as opposed to using fluorescent was calculated at 50%.

Its design – which was done by Toronto-based architectural firm Zeidler Partnership Architects – aims to reflect the economic and commercial power of the Kingdom of Saudi Arabia; that is, a futuristic image of sustainability. The challenge Owned by Awtad Al Akaria Company, the R1.1 bil- lion project was on a tight budget, but at the same time, needed high-quality and sustainable system solutions. The light fittings were all imported from China, but the lighting designers knew that the per- formance and durability of any luminaire can be di- rectly affected by the drivers. They primarily wanted a highly-reputable DALI Drivers manufacturer, and

JCDECAUX AND ELLIES SOLUTIONS CREATE EFFICIENT, LIVEABLE CITIES

A s sustainable development has become a major global issue, cities around the world are aiming to reduce their environmental footprint and showing a growing interest towards energy-saving issues. For JCDecaux, the integration of Sustainable Development in the company’s strategy facilitates the management of risks related to environmental and social challenges and is a driver of innovation and an asset to medium and long-term economic development. The increase in its activities in more than 80 countries worldwide means that the company has a network of more than 600 000 furniture items in operation. Furniture energy consumption represents 80% of JCDecaux’s energy consumption. JCDecaux South Africa, in collaboration with Ellies Commercial Solutions – a leading Southern African manufacturer, importer, wholesaler and distributor of quality lighting, electrical and electronic products and solutions – conducted a pilot study to reduce the energy consumption of billboards across Gauteng. Ellies recently launched a range of ALS Floodlights which have an Ambient Light Sensor built in to automatically switch on when the Lux level drops below 400 lux and switch off when the lux reaches 400 lux. This process eliminates floodlights from being left on during the day or customers having to purchase expensive day night switches to provide the same product functionality. LED lighting is highly efficient, long lasting, environmentally friendly and inherently controllable – enabling both new and traditional applications of light. The objective of the pilot study was to evaluate if the new range of ALS Flood lights would operate at 100% illumination until the pre-determined time i.e. 1 am. The Ellies LED ALS Floodlight with proprietary Crystal Driver technology automatically reduced the output of the flood lamp to 40% from midnight and switched off the floodlight at sunrise. This technology allowed significant energy saving while also extending the life span of the flood lamp. Furthermore, the Colour Rendering Index (CRI) was increased from +80 to CRI +90. The higher CRI value allows the true colours of the medium illuminated to be displayed. “Our engineering capabilities allow us to design and manufacture bespoke products for specific applications. Our partnership has allowed us not only to deliver on our customer expectations but to develop technologically advanced lighting capabilities in a cost-efficient manner” says Gary Gillingham, Ellies Group Head: Lighting.
