Context

As India’s urban population grows, adopting high-performance buildings (HPBs) can address sustainability challenges and meet climate goals. HPBs optimise energy efficiency and enhance occupant well-being, positioning them as vital for future urban development.

Importance of Sustainability in the Building Sector

• Buildings contribute significantly to global emissions, especially in rapidly growing cities.
• They account for 40% of total global energy consumption over their lifespan, leading to about 28% of energy-related carbon emissions.
• In India, buildings use over 30% of national energy and generate 20% of carbon emissions.
• As urbanisation increases, the demand for sustainable construction becomes more urgent to meet climate goals.

High-Performance Buildings (HPBs)

HPBs aim to reduce environmental impact and improve occupant comfort, exceeding basic regulatory requirements. Unlike green buildings, which focus on certification and meeting sustainability benchmarks, HPBs emphasise peak efficiency in all aspects of their design. HPBs use advanced technologies like energy-efficient HVAC systems, smart lighting, greywater recycling, and real-time performance monitoring.

Benefits of High-Performance Buildings

• HPBs offer both environmental and operational benefits, helping buildings achieve long-term efficiency.
• Smart systems enable continuous monitoring, ensuring resource optimization and extending the lifespan of building systems.
• These buildings have higher property values and lower maintenance costs due to better design and automation.
• They also promote occupant well-being through superior air filtration, natural light, and thermal comfort.

HPBs and Urban Development in India

• HPBs help cities manage resource scarcity and rising temperatures by promoting resilience and self-sufficiency.
• They reduce the strain on public infrastructure and foster healthier indoor environments.
• By adopting HPBs, India can transition to a low-carbon economy while addressing the challenges of rapid urbanisation.
• HPBs are future-proof investments, delivering value while addressing environmental and economic pressures.
