The inspiration to build temperature regulated green homes at IIT Kanpur in 2012 came from:

Correct option is D

Ans. (d) Cocoon structure

Sol.
The inspiration for constructing temperature-regulated green homes at IIT Kanpur in 2012 stemmed from the unique properties of the cocoon structure. Researchers at IIT Kanpur, in collaboration with the Defence Research and Development Organisation (DRDO), studied the natural architecture of a cocoon, particularly its ability to maintain a stable internal environment despite external temperature fluctuations.

The cocoon's asymmetric membrane allows selective gas exchange, facilitating the expulsion of CO₂ without letting it enter, thereby preventing CO₂ buildup inside. This property inspired the design of homes that could regulate temperature and air quality naturally, reducing the need for artificial heating or cooling systems.

The study highlighted how the cocoon's structure creates an optimal living condition for the pupa, which was translated into architectural design principles for sustainable housing.

Information Booster:

• Cocoon Structure in Architecture: The cocoon's ability to regulate temperature and gas exchange has been a subject of interest in biomimicry, influencing designs in sustainable architecture.

• Bioclimatic Design: The IIT Kanpur green homes incorporated bioclimatic design principles, utilizing natural materials and passive design strategies to achieve thermal comfort without relying on mechanical systems.

• GRIHA Rating: The green homes at IIT Kanpur received a five-star GRIHA (Green Rating for Integrated Habitat Assessment) rating, recognizing their environmentally friendly design and construction.

• Sustainable Materials: The construction utilized eco-friendly materials and energy-efficient designs, aligning with sustainable building practices.

• Energy Efficiency: The homes were designed to minimize energy consumption through optimized building envelopes and the use of renewable energy sources.

• Research Collaboration: The project was a collaborative effort between IIT Kanpur's Department of Chemistry and DRDO, showcasing interdisciplinary research in sustainable architecture.
