Why in news
IIT Guwahati researchers developed energy-efficient bricks using Phase Change Materials (PCMs) and biochar to regulate building temperatures in hot, humid regions.
Background
The research team led by Bitupan Das and others embedded OM35 PCM into bricks to absorb daytime heat and release it at night. Biochar was integrated into the bricks specifically to prevent leakage of the PCM.
Facts for Prelims
- S&TOM35 PCM: Phase Change Material identified as most suitable for hot, humid regions in the study.
- FactBiochar: Used as an additive in the bricks to prevent leakage of the embedded materials.
- BodyIIT Guwahati: The institution responsible for the development of the energy-efficient bricks.
For Mains
Q. Discuss how the integration of Phase Change Materials and biochar in construction materials can contribute to climate-resilient infrastructure in tropical regions.
Dimensions to cover in your answer
- Economic barrier: High initial manufacturing costs of PCM-integrated bricks compared to conventional masonry
- Awareness gap: Lack of technical knowledge among local builders and contractors regarding passive cooling technologies
- Policy requirement: Need for building codes to incentivize the use of energy-efficient materials in urban planning
Keywords: Phase Change Materials · Passive Cooling · Biochar · Climate-Resilient Infrastructure · Thermal Regulation
