Bengaluru, December 12, 2025: Tata Steel, in partnership with constructsteel – the steel construction market-development programme of the World Steel Association – today inaugurated a pioneering steel-based Zero Energy Building (ZEB) constructed using advanced Light-Gauge Steel Frame (LGSF) technology.
T V Narendran, CEO & Managing Director of Tata Steel, inaugurated the 1,836 sq. ft. facility in the presence of Dr Edwin Basson, Director General of the World Steel Association (worldsteel). Built in just 3.5 months, the facility represents a significant step in India’s move towards net-zero, energy-efficient, and climate-resilient infrastructure.
“The steel-based zero energy building reflects the future of construction,” commented T V Narendran. “Our partnership with constructsteel showcases how modern, energy-efficient, and low-carbon solutions can be replicated at scale across India and integrated into mainstream infrastructure.”
The LGSF technology, where precisely manufactured steel sections are assembled like a frame, allows the building to achieve a tight envelope with minimal air leakage, better insulation, and reduced energy loss. Steel makes the structure lighter, faster to build, and highly durable, while its recyclability ensures lower long-term environmental impact.
Designed to produce as much energy as it consumes, the steel-based ZEB combines ultra-low operational energy demand with on-site renewable energy generation, achieving annual net-zero energy use. The building uses high-performance glazing, well-insulated walls & roof panels, and natural ventilation wherever possible. To generate clean power on-site, it uses rooftop solar panels and Building-Integrated Photovoltaics (BIPV). The building also includes rainwater harvesting and low-flow fixtures to optimise water consumption.
