NTPC Limited, India’s largest integrated power utility, has unveiled its innovative eco-friendly and affordable housing solution, ‘Sukh’ Eco-house in New Delhi.
The eco-houses utilize approximately 80% ash and ash-based products from thermal power plants in their construction, offering a revolutionary approach to rural housing and showcasing the company’s commitment to sustainability and zero-carbon emissions.
Built with innovative interlocking wall blocks made from ash, these structures do not require any sand, cement, steel, or mortar, significantly reducing costs and construction time. The use of ash-based building material in these eco-houses eliminates the requirement of cement and natural aggregates, leading to lower carbon emission and prevention of topsoil erosion.
A typical house, spanning 30 square meters and featuring a drawing room, bedroom, kitchen, and toilet, can be constructed for just Rs1,50,000 in a span of 15-20 days. This method ensures durability, as demonstrated by its resilience to diverse weather conditions, including rain, storms, and high winds, for over two years.
Moreover, the houses achieve a remarkable 75% reduction in carbon emissions compared to conventional construction methods. From the foundation to the roof, and even the window and door frames, the entire structure is built using ash-based materials. The design allows the house to be dismantled and re-erected with minimal damage, adding to its practicality and longevity.
The eco-houses align with the Pradhan Mantri Awas Yojana-Gramin (PMAY-G), providing a scalable and eco-friendly model for affordable rural housing. By addressing waste management and promoting the reuse of industrial byproducts, NTPC’s initiative paves the way for sustainable construction practices. Besides these eco-houses can also be powered by solar energy, thereby strengthening India’s Net Zero commitments.
