Envisaged as the catalyst for a
new central business district in Lusail city, the newly built Lusail Plaza Towers
have already become a landmark in Doha as well as an unmissable background for
the many celebrations of happy football supporters at FIFA World Cup 2022. Designed
by Foster + Partners as part of a wider masterplan for Lusail City, which
includes an 80,000-seat stadium that will host the upcoming final of the 2022
World Cup, Lusail Plaza Towers are soon to become the headquarters for Qatar
National Bank, Qatar Central Bank, Qatar Investment Authority, and Qatari Diar.
This group of four imposing towers
- located at the end of the commercial boulevard linking the new Lusail Stadium
to the corniche - consists of two 70-storey skyscrapers and two 50-storey high-rises.
The taller towers reach up to the incredible height of 310m, which ranks them
among the highest buildings in Doha. Symmetrically arranged around a central
plaza, each of the four towers features an oval plan that twists by 90 degrees
as the building rises to give the impression of an asymmetric structure of
unique shape and design. At the base, a network of podium buildings surrounds
each tower providing support facilities with shops, cafes, an events and
exhibition centre, gyms, banks, and restaurants, making Lusail City one of the
key venues for World cup fans.

design as a key driver in the project, the towers’ façades have been clad in
marine-grade aluminium in response to climate and location, and covered
with projecting profiles to shade the glazing from the harsh sun, while
preserving view out and daylight. The sustainable managing systems of the
towers allow maximum reduction of the general energy consumption and water wastage,
targeting the highest level in the regional Global Sustainability Assessment
System. According to the ecofriendly guidelines of the buildings, efficient LED
lighting and advanced automation controls were a mandatory requirement in order
to reduce the site energy demand by 35% when compared to a baseline building.
the contribution of different lighting designers working on the project for
about three years, the developed lighting concept of Lusail Plaza Towers
required the use of powerful LED fixtures which could be able to deliver a high
illumination level up to the top of the four skyscrapers. According to the
project prerequisites, our engineers have developed a custom version of CAPITAL
200 that could win the bid assuring the required luminous flux, uniform light
distribution, and low consumption rates.
1040 custom CAPITAL 800 MC made up of 4 units of CAPITAL 200 MC each, linked
together by a specifically manufactured metal support, were installed on top of
the podium buildings in order to allow a perfect illumination of the four
imposing towers. These double bank fixtures are fitted with multichip LEDs using quad-color LEDs for superior color mixing
directly at the lens enhancing seamless light distribution and smooth colour
transitioning. Fitted with independent pixels clusters of 4
multichip LEDs each, these floodlights also allow the creation of dynamic
visual patterns for a truly impressive lighting
All of the
LED fixtures were delivered in RGBW colour configuration with a spot beam angle
of 7°. Divided in 4 plots, the Capital 800 units have been aligned in diagonal
rows, according to a specific scheme in order to assure even white light and
colour distribution on the four towers. Besides a different spacing between
each CAPITAL 800 MC unit, a 25° tilting position was calculated as optimal
inclination for the fixtures. 328 units have been used to light up each of the
two taller towers, while 160 units were dedicated to each of the lower towers. Stored in
a specific control room provided with air conditioning system where temperature
and humidity levels are kept under constant supervision, the general control
system management of the lighting equipment is entrusted to a digital control
gear with professional cloud software that allows the remote control, either
independent or synchronized, of the four towers lighting. A complete cabin
rack, containing data server, ethernet interfaces, as well as DMX nodes has been
also been provided to allow smooth professional
operation. Testing, commissioning and programming of the whole system have been
carried out by Griven’s engineers in order to assure the utmost system
reliability and optimal performance. Lusail Plaza Towers can now be considered
the key venue of Lusail City, an unmissable attraction for tourists and
visitors, and its gorgeous illumination contributes to strengthen its
reputation all over the world.
