The Lighthouse Tower, planned for construction in the Dubai International Financial Centre (DIFC), was to be the first low-carbon building in the United Arab Emirates. Site preparation work commenced in 2008, but the project was delayed in 2009 due to the Global Financial Crisis, and later cancelled. The DIFC has since unveiled a new plan for the undeveloped site in October 2013.
What made the Lighthouse Tower so interesting was its emphasis on being eco-friendly. The structure would rise as two separate towers, bridged from level 10, all the way up to approximately 300 meters above ground. The structure was to hold a number of sky gardens. Three large 225 kW wind turbines, 29 meters in diameter, on the building’s south-facing side were going to generate electricity. The building was also going to be clad in 4,000 solar panels to generate additional electricity. It was estimated the tower would reduce its overall energy consumption by 65%, and its water consumption by 40% in comparison to an equivalent building.
The submission by UAE-resident South African architect Shaun Killa for the iconic, 400m tall Lighthouse Tower in Dubai, United Arab Emirates (UAE) was commended for demonstrating in a convincing manner that high-rise buildings also have significant potential to be designed and constructed to meet sustainability targets. The 53-story building incorporates passive cooling, optimizes use of daylight through a responsive façade, and will include wind turbines and photo-voltaic panels to generate most of the energy needs of the building – and is therefore projected to achieve energy savings of around 50% compared to a conventional office tower.Sustainable construction projects applauded across Africa Middle East » pour en savoir plus (French) »
The jury commended this project because it demonstrates in a convincing manner that high-rise buildings also have signiﬁcant potential to be designed and constructed in compliance with the globally-accepted standards for sustainable construction. This high-tech structure is a 400m-tall, 53-storey twin tower mainly for “class A” ofﬁce use.
Optimization of passive cooling and daylight through a context-responsive façade is expected to achieve energy savings of over 50% compared to Dubai standard practices. In addition, the three horizontal-axis wind turbines at a diameter of 29m each and 6,000 photovoltaic panels integrated into the façade will generate most of the energy needs of the building.
Many other design provisions will contribute to substantial savings with regard to water and materials consumption. In the context of the United Arab Emirates, where emerging wealth – mainly propelled by oil revenues – is rapidly changing the built environment, high-rise buildings will continue to dominate the skylines of the cities. Accepting this fact, the Lighthouse Tower will become a benchmark in this region with regard to energy efﬁciency and renewable energy sources.See more
The words “Dubai” and “sustainable construction” do not often appear in the same sentence. That is set to change, thanks to strong environmental regulations and visionary projects such as the Lighthouse tower with low-carbon footprint. The elegant skyscraper, in which three massive wind turbines have been integrated, will consume around 65% less energy than its peers.Download project entry poster (PDF, 2.10 MB) »
Our website search engine covers the web pages including project descriptions and expert profiles, PDFs, images and videos on the LafargeHolcim Foundation website. To improve your search results, here are some tips:
Our search defaults to term-pairing AND. If you search sustainable construction - then the search engine will look for any items containing sustainable AND construction
photovoltaic OR solar
Looks for either word
(clay OR mud) AND (school OR university)
Combine alternative terms for more specific searching
Excludes a term from results, automatically ANDs other terms listed
Use quotation marks to search for a specific phrase or combination
Asterisk (*) matches any word or phrase - so archit* will find architect, architecture, architectural as well as architrave
