Tata Steel has registered a major technological achievement in the construction sector by designing a steel building that will generate all the electricity it needs. This building named ‘Zero Energy Building’ (ZEB) was inaugurated on Friday by Tata Steel CEO TV Narendran and World Steel Association DG Dr. Edwin Basan inaugurated. This project was prepared under the ‘Construct Steel’ program of the World Steel Association.

In simple language, it is such a modern system, in which instead of brick and mortar, the structure is erected by connecting a pre-prepared steel frame with nuts and bolts. Like a block puzzle, this technology ensures extremely accurate, fast and quality construction. As a result, the entire 1,836-square-foot building was completed in just three and a half months. Due to the steel structure, the building is light, earthquake resistant and extremely durable. ‘Zero’ electricity bill How the building’s design is based on the energy saving principle. High-quality insulation is installed in the walls and ceiling, which prevents heat from entering from the outside and keeps the coolness inside. Due to this, there is little need for AC and heater. Solar panels on the roof and ‘Building Integrated Photovoltaics’ (BIPV) are installed in the walls. This plant will generate as much solar energy as the building needs in a year, keeping its net energy bill at zero. Describing it as the future of the construction sector, TV Narendran said that this model will be a milestone for low carbon infrastructure in India. Globally, traditional construction activities account for approximately 37-40 percent of total carbon emissions. As such, the LGSF technology consumes less water and the entire steel structure is 100 percent recyclable, making it extremely environmentally friendly. Rainwater harvesting system and modern water-saving faucets have also been installed in the building, completely establishing it in the category of ‘Green Building’.
