US$1m solar air-con for ESAB head office
ESAB head office pioneers large-scale solar air-con in Dubai
A US$1m solar thermal cooling system, representing the first large-scale application of this technology in Dubai, is operational at the new ESAB head office in JAFZA.
Pax-Kent International LLC was the architect, consultant and project manager. The system was installed by Kylsystem of Sweden. Kingspan Renewables suppled 300 square metres of solar vacuum tubes, while the Climatewell supplied six absorption units.
“The benefits of this system are considerable, as there is 65% to 70% saving on the energy costs compared to traditional air-con systems,” says Pax-Kent International LL joint president Kent Johansson.
The system uses roof-mounted solar tube collectors to provide hot water for the six absorption chillers. These, in turn, provide cold water to air-handling units, also located on the roof. Cold air is then circulated through the precast, hollow-core concrete ceiling slabs of the building, providing radiant cooling and fresh air.
The project has garnered LEED Platinum certification, representing a significant achievement for industrial buildings in Dubai. “Green issues and health and safety are not high on our agenda; they are at the top of our agenda,” says ESAB Middle East FZE MD Johan Fransson.
Architect Middle East named the project as one of the region’s top five green buildings, which was also short-listed for the Sustainable Project of the Year in the 2010 Architect Middle East Awards.
