The Lighthouse: An Innovative Green Skyscraper
by Justin Thomas, Virginia on 05.15.07

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.




















Absolutely Beautiful
We should starty putting solar panels on all new buildings. Great ideas, that building is very attractive.
She's a beauty.
When will we have skyscrapers which produce 100%+ of the electricity which they consume?
AWESOME.
Too bad we can't be as innovative here in the US.
It might be interesting for all major cities to have something like this available as a resource for public services. It could possibly provide reduced-cost power for traffic lights, street lights, etc...and the cost of construction could be paid over time by cell phone tower space and possibly some advertising space on the outside of the building (only on the first 2-3 floors). So the initial construction cost could be financed over time, but the payments made through income earned. Net cost to the public: zero, but long-term benefit to the public is that local taxes could be reduced because power needs for necessary resources would become much, much cheaper.
That's freakin awesome!!!
A steel frame? As opposed to...?
You gotta remember that whilst solar panels are great for generating electricity, they get VERY hot during peak sun periods, and reflect insolation towards ground level.
Most (if not all) of the "green" power this building would produce would go toward pumping water up to the top. Hugely tall buildings like this also use more materials per square foot.
Let's stop applauding this "green" design and see it for what it is, a greenwashed testament to someone's ego.
High-density buildings aer actually quite green. Condos are usually greener than single-family houses, even if the former are just "regular" and the latter "green"..
Finally! I've been advocating this idea for years! It's not like it takes rocket science to figure out a way to do this. I can only hope that governments around the world take note of this and put some effort into making this a widespread phenomenon! Hell, I can think of about a dozen buildings around Canada that could be retrofited with solar panels and turbines on the roof so that there not using up as much non renewable resources. I say, A turbine on every roof! Can you imagine the savings? I realize that this kind of thing is expensive, but at the same time, we will be saving money over the long term. (too bad most exec's think short term... money money money!!)
Think about all the birds that will be killed by those awful blades. We must return to mother earth and eat only what comes from the ground. Hark, hear the trees call your name back to the forest my children!!
It's funny hearing the enviro-whackos complain. They type on their computers, and whine about anything anyone tries to do to be green... Never mind how ironic it is that they complain about any use of electricity, etc., but won't give up their Ipods or stop and think about how much energy and resources went into making their computer on which they're using to blast other people's green efforts. The fact is: a tall building has less of an environmental impact than the same amount of office/residential space would have if they were spread out across acres of land.
If any environmentallyincapabilists want to challenge my contribution, understand that for the past seven years I've been working to (successfully) reduce greenhouse gas emissions from power plants, and also help the world move to a hydrogen economy. I think this building is great. It's not a cure-all, but a big step in the right direction, and I wish the US would do something like this.
wandering, what's the budget for this project.
go green tower!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
It's hard to see how this can be claimed as a "green" building when the UAE has extremely dubious labour practices. How many slave workers will die in the process of building. There's more to green than a solar panel.
Stunning. When I heard about this project, I imagined a windmill on top of a square box. The architects in Dubai are out of this world.
