Project

Lighthouse: An Innovative Green Skyscraper (Dubai, UAE)

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.

In setting a new benchmark for Dubai, the design aspires to be a LEED platinum rated low-carbon commercial building which will aim to reduce its total energy consumption by up to 50% and water consumption by up to 40% compared to the current Dubai standard design. Atkins was commissioned to carry out a separate sustainability design study to identify innovative ways of achieving this goal.

Design provisions include passive solar architecture, many low energy, low water engineering solutions, recovery strategies for both energy and water and integrated renewables and photovoltaic panels within the façade. For example:
• a digital lighting system is proposed with daylight and movement sensors to reduce energy consumption
• graywater recycling to service the irrigation needs of the landscaped areas
• flow restrictors on taps and showers as well as low flushing WC's along with waterless urinals
• 150 solar water collectors to meet the hot water requirements for the whole building.

Seven levels of parking are provided over the podium, ground floor and five basements offer 1706 parking spaces. The first floor houses a 250 seat restaurant. A swimming pool sits on the third and fourth floor with a fully equipped gym, clad in a bubble like structure made from glass and metal floats above the pool deck.
