Introduction: Give a brief context to the question

Body: Impact of construction sector on climate and significance of energy-efficient solutions

Conclusion: Way forward

India is currently experiencing an unparalleled construction surge, erecting more than 300,000 housing units each year. While this growth presents economic prospects and enhances living conditions, it also presents substantial environmental hurdles. The building sector, a significant energy consumer, is responsible for more than 33% of India’s electricity consumption, exacerbating environmental degradation and climate change.

Impact of the sector on urban sustainability in India

  • Degradation of the environment: Construction uses a lot of resources, which results in deforestation, dust and debris contamination of the air and water, and a rise in CO2 emissions. Construction-related rapid urbanization causes habitat loss, changes in land use, and greater strain on natural resources and infrastructure.
  • Waste generation: Waste from construction and demolition overwhelms landfills and puts pressure on waste management systems.
  • Increase Carbon Emissions: Conventional construction practices often rely on energy-intensive materials like cement and steel, contributing to significant carbon emissions during the production and construction phases.

Significance of adopting Sustainable solutions

  • Energy efficient Materials: Utilizing recycled steel, fly ash bricks and prefabricated elements reduces energy consumption during production and construction. However, sustainability concerns of materials like Autoclaved Aerated Concrete (AAC) blocks, red bricks, fly ash, and monolithic concrete (Mivan) when tested show AAC blocks offer a better balance between embodied energy and construction time than red bricks and monolithic concrete.
  • Green building practices: Integrating solar panels, rainwater harvesting, and energy-efficient appliances in buildings minimizes their environmental footprint. Initiatives like the Eco-Niwas Samhita (ENS) and the Residential Energy Conservation Building Code are steps in the right direction.
  • Reduce reliance on Conventional resources: Utilizing renewable energy sources like solar panels and incorporating green roofs and rainwater harvesting systems can further enhance the sustainability of buildings and reduce reliance on non-renewable resources.

Conclusion

In conclusion, achieving sustainable construction presents formidable obstacles, yet it remains indispensable for fostering a more environmentally friendly future. Through the reimagination of construction design and methodologies, the development of cutting-edge walling materials, and the promotion of a sustainability ethos, we have the potential to construct resilient, energy-efficient buildings that harmonize with environmental objectives and greatly enhance the well-being of communities at large.
