Courtyards, jaalis and chajjas in old Indian homes — the passive cooling lessons modern flats quietly lost
• Traditional Indian homes employed courtyards, jaalis, and chajjas for passive cooling, reducing the need for air conditioning.
• Modern apartments often lack these features, leading to higher energy consumption.
• Reintroducing these techniques can improve comfort and promote sustainable building practices, reducing energy bills and environmental impact in India.
Why It's Important?
Courtyards, central open spaces, enable natural ventilation through temperature differences. Hot air escapes, and cooler air enters, lowering the building's temperature. Water features and plants in courtyards enhance cooling through evaporation and transpiration.
