LAGI 2019 Abu Dhabi “Return to the Source”  invited creatives to design an iconic concept for a landmark site within Masdar City, Abu Dhabi using renewable energy technology as a medium of creative expression to provide on-site energy production consistent with the master plan of the city.

Masdar is the Arabic word for “source.” As the name of Abu Dhabi’s multifaceted renewable energy company and most ambitious low-carbon development, it is a reference to the Sun, the source of energy that sustains life on Earth, drives the wind and waves, and that over millions of years powered the transfer of ancient carbon dioxide out of the atmosphere and into the ground, creating a climate habitable to humans.

Masdar City’s Goal: to have a feasable and constructable design concept pushing the boundaries of what is possible using today’s renewable energy technologies. To do so a capital cost restriction has been imposed as part of the design brief. Therefore the budget of each proposal had to respect the maximum estimated cost of 20.00 USD per watt installed.

A-oma’s Goal: to continue our research on the cooperation, at the urban scale, between private and public spaces in the production of renewable energy. The site of Masdar had for us an outstanding potentiality considering its central location in the region and the future needs – in terms of energy consumption – of the city of Abu Dhabi. In order to set a cultural link with the region we took our inspiration from the Arabic Script (see more details below).

Intro. Calligraphy is considered the quintessential art form of the Islamic world and its prevalence is not simply related to its non-figural tradition; it rather reflects the centrality of writing and written text, as according the tradition “the first thing God created was the pen”. Real “source” of the Islamic culture, calligraphy is revered as a medium of infinite duration and visual expression of faith and knowledge. It is noteworthy that the United Arabic Emirates host every other year the Dubai International Calligraphy Exhibition as the climax of the cultural scene of the year, as well as the outcome of the region’s social identity. With our proposal, then, we envision a fertile dialogue between Dubai and Abu Dhabi under the aegis of the Arabic script that we use as a “source” inspiration for our landart work. As the Islamic calligraphy has developed a vaste range of styles we decided to assign a representative style to each of the two areas of the site. The Square Kufic (kufi mrabba’) to the north west area as the link to the past and a more curvilinear contemporary Naskh-like style to the south-east as the link to the future. The whole forms a unique rectangular layout: the Masdar Calligraphy.

The kufilab: a labyrinth and a laboratory of energy. The North-West area of the site hosts the Kufilab an installation of roughly 2318 m² originated by the vertical extrusion of a urban-scale Kufic text creating a sort of outdoor labyrinth with chambers. The hemstitch roof and the elevations are cladded with modular colored solar panels produced by the Dutch company Kamaleon Solar. The result is a monumental and extremely modular complex taking advantage from the geometric regularity of the Kufic style. The interiors are characterized by a series of “open chambers” carved in the mass of the volume. Each chamber presents one of the historical developments of the art of script both in the past as in the future. The quite infinite range of paths allows a non-conventional discovery of the Islamic calligraphy that can be adjusted year after year.

The Wind Pipes Park: producing and saving energy. The South-East area accommodates a lawn punctuated by 85 curvilinear characters and a series of orange dot-like elements for power storage. Each of the character is composed by a vertical pipe and a curvilinear base. On top of each of the 25 m high pipes there is a 2.40 m high VAWT produced by the company WINDSIDE. While creating a playful urban space composed by circular spaces, the aim of each of this element is twofold:

1) Produce energy with the VAWTs;

2) Create a passive system of Canadian wells;

The Eolic system has a nameplate power of 259 Wp and a production of more or less 21 218 kWh per year (see more details in the next paragraphs).

The Canadian well system works as follows: below the VAWT an air intake lets air into the hollow pipe. A series of small fans draw the air to the ground while gradually cooling it. After the circular base the pipes go 3m below ground following a path of at least 30 m in order to reach the dew point at the stable temperature of 15° C. The humidity contained into the air is condensed and stocked into several tanks below ground to be used for irrigation purposes, while the cooled air is injected to the close-by buildings.

Budget, energy production and costs

The Kufilab

Te Kufilab has been conceived with a 1mx1m modular grid and it will be realized with the following main materials:

Prefabricated concrete walls (1.00 m x 8.00 m x 0.16 m) tinted in the mass

Photovoltaic Solar Panels Kamaleon Solar Color Blast.

Deactivated concrete slabs

 

The exterior surfaces are cladded with modular panels (1m x1m) with an overall surface of 3892 m². The panels used are ColorBlast of Kamaleon Solar (www.kamaleonsolar.com) We involved the company from the early stage of conception and we can declare the following data:

 

Average Nameplate Power: 100 Wp per 1mx1m panel

 

Kufilab Nameplate Power: 389kW

 

Budget: 3892(m²) x 100(Wp) x20 ($)= 7.784.000 $

 

Year Production: 498.218 kWh/yr (conservative estimate)
