Companies that are prominent in their local business community often feel a responsibility to lead by example. This is certainly true of Ooredoo, the mobile phone operator. Ooredoo is based in Doha, Qatar, and is active in the Middle East, North Africa and South-East Asia. Altogether, Ooredoo has some 164 million subscribers and employs over 15,000 staff. However, the desire to lead by example is not only felt by the company, it is also a driving force for Ibrahim Awad Mohamed Siddiq, the electrical engineer responsible for Ooredoo’s head-office in Doha.



The Doha head-quarters building dates from 2007 and has 28 floors. Most of the lighting was using 2 x 40W PLL fluorescent lamps, with 2 x 26W and 2 x 18W compact fluorescent downlights in the corridors. The average lux level being achieved in most of the offices was about 200 lux – very low by current standards.

Ibrahim is a member of the Qatar Electrical Regulations and Standards Committee, so he was anxious that the Ooredoo HQ building should be a showcase for modern and energy-efficient building services. In 2017, as part of an overhaul of the entire building, Ibrahim argued for a complete replacement of the building’s lighting. To help gather information on costs and the likely payback he approached NVC International and their local sales engineer, Phoebe Shen.



Replacement lamps were considered as an option but were rejected because they were not significantly less expensive than complete new fittings.

To show the maximum energy savings, Phoebe suggested that Ibrahim should use occupancy sensors, dimmable fittings and daylight harvesting. Sadly, this approach was not cost-effective for Ooredoo because of a government requirement that they keep many of the office lights on throughout the night. This may seem to be an unusual condition, but the Ooredoo building is in a prominent position on the waterfront and contributes significantly to the view of Doha from the other side of the bay. So, NVC’s proposal was simplified to some very efficient fittings, designed to deliver the required lumens for the lowest possible power consumption.

Based on Phoebe’s calculations, Ibrahim would be able to achieve a payback in about 18 months. This was enough to convince the CFO to release the necessary funds for work to begin. Now, in Q2 2019, the lighting installation is almost complete. A total of about 4,000 60x60 panels have been installed, with a similar number of LED downlights.



Generally, feedback from the staff has been very positive, though it has taken a few days for some people to grow accustomed to the new lux levels. These have risen from an average of 200 lux to the recommended level (EN12464) of 500 lux, while the lighting power consumption has dropped by 50%. Another major advantage of this retro-fit programme is that for a relatively modest financial outlay on new lighting the entire office appears brighter and newer than before.

Overall, the retro-fit programme has been a big success and Ibrahim is now considering a similar programme for Ooredoo’s other buildings in Doha.
