The Lighthouse is another innovative green skyscraper to be constructed in Dubai. For energy generation, it will have three enormous 225 kilowatt wind turbines (29 meters in diameter), and 4000 photovoltaic panels on the south facing façade. To optimize performance and operational periods, the turbines have windward directional wind vanes or limited yaw.Designed by the Atkins group, the 400-meter office tower aspires to reduce its total energy consumption by up to 65% and water consumption by up to 40%.
To achieve this goal the building makes use of extensive passive solar architecture, and many low water engineering solutions including recovery strategies for both energy and water.
During the development of the design Atkins will map and manage the embodied energy content of the building and select materials from sustainable sources, so that impact on global resources is controlled. Already, this is leading designers to consider a steel frame solution for this structure.
Additionally, features such as floorplates interconnected by micro-atria and the inclusion of inter connecting vertical gardens are being actively considered to enhance the social aspects of this building.
According to Atkins, this unique building, with a total construction area of 140,000 sq m, will become a working prototype for low carbon towers within the region and a model for more sustainable developments in the future.
