Sustainability is not a cost but a measurable, monetisable performance advantage, a strategy Qatar has steadfastly followed and a model worth emulating, according to a top official of EnergyX, South Korea's global leader in energy optimisation and now shifted its global command centre and international headquarters to Doha.The move behind the creation of EnergyX – where deep tech, architecture and sustainability converge – has come in view of accelerating global demand for decarbonised buildings, its chief executive officer Sean Park told Gulf Times on the sidelines of the Mobile World Congress, which concluded Wednesday.Quoting the World Green Building Council, he said buildings account for about 39% of global carbon emissions, making the built environment the world’s most significant single source of emissions — and therefore one of its greatest opportunities.“That statistic hit us with clarity,” recalled Park, who had earlier served as a board director at Tapas, an entertainment-technology company acquired in Silicon Valley for $510mn.The Building-Integrated Photovoltaics (BIPV) market was valued at approximately $23.6bn in 2023 and is projected to grow to between $80bn and $90bn by 2030, with a compound annual growth rate (CAGR) of around 21%.EnergyX stands as a global leader, with more than 2,000 projects, more than 300 IP assets, and the groundbreaking EnergyX DY-Building — the world’s first certified Plus-Energy Building achieving 129.6% verified energy self-sufficiency.Highlighting Doha's central role in its global strategy; he said from its base in Qatar, EnergyX now directs a growing global network — integrating strategic acquisitions worldwide while co-ordinating its worldwide operations and R&D (research and development) from Qatar”.Park emphasised that Qatar is not simply a regional office — it is the anchor point for EnergyX’s global operations, advanced R&D vision, and its drive to reshape the future of building technologies.EnergyX, JMJ Group Holding and Hexa Tech have entered into a pact to establish a trio of industrial initiatives in the country, including an advanced production plant centred on free-form design-for-manufacturing-and-assembly (DFMA) and energy-optimisation technologies to boost the country’s high-value manufacturing.By putting Qatar at the centre of its worldwide operations, systems integrations, manufacturing, and R&D; he said it will expand local hiring, deepen collaborations with universities and research institutes, and broaden its intellectual-property portfolio from Doha — positioning Qatar as the origin point for technologies that enable energy-sovereign buildings and districts worldwide.Finding that buildings and construction account for over one-third of global final energy consumption (according to the International Energy Agency), he said "this places EnergyX at the front line of one of humanity’s most critical climate challenges — and positions Qatar as a global hub for the solutions needed to address it."EnergyX will build high-skill teams and collaborate with government, leading Qatari business groups, universities, and research institutes to accelerate technology transfer, specialised training, and workforce development tied directly to the factory and research centre, according to Park.
