High-Performance Buildings and Sustainable Future

Understanding High-Performance Buildings (HPBs)
• HPBs are crucial in reducing environmental impact, energy consumption, and improving occupant comfort.
• They account for nearly 40% of total final energy consumption globally, leading to approximately 28% of energy-related carbon emissions.
• In India, buildings account for over 30% of the national energy use and 20% of its carbon emissions.
• As urbanisation accelerates, India risks surpassing global benchmarks for energy efficiency and carbon emissions in buildings.
What are High-Performance Buildings (HPBs)?
• HPBs aim for peak efficiency in every aspect of their form and function.
• They use advanced technologies and smart design strategies to track performance metrics in real-time.
• HPBs leverage site-specific design approaches, such as natural lighting, ventilation, and terrain water management using sustainable materials, insulation, and low U-value windows.
• Advanced technologies include energy-efficient HVAC systems, greywater recycling, rainwater harvesting, smart lighting controls, and advanced metering.
Examples of HPBs in India
• Unnati in Greater Noida features a façade designed according to the Sun’s path in the local sky to improve thermal comfort and reduce glare.
• Indira Paryavaran Bhawan in New Delhi uses an advanced HVAC system that takes advantage of natural convection and reduces energy consumption.
Benefits of HPBs
• HPBs offer environmental benefits and address long-term operational challenges.
• They create a holistic environment where technology, design, and sustainability intersect to enhance building performance.
• HPBs that take advantage of automation and artificial intelligence can create intelligent ecosystems.
How can HPBs help India’s cities?
• HPBs offer resilience through adaptive, self-sufficient structures and promote social well-being by nurturing healthier indoor environments.
• They offer a proactive solution that positions the built environment as a driver of the country’s transition to a low-carbon, more sustainable economy.
