1. Climate of Cochin and Its Impact on Vernacular Architecture A Study of Climatic Influence on Traditional Built Forms Presented by: [Your Name] Date: [Add Date]

2. Geographical Location • Southwest coast of India along the Arabian Sea • Coordinates: 9.9312° N, 76.2673° E • Coastal, low-lying terrain • Proximity to sea affects climate and building design

3. Climatic Conditions of Cochin • Tropical monsoon (Köppen: Am) • Temp: 23°C – 33°C • Rainfall: ~3200 mm/year (mostly June–Sept) • Humidity: 70–90% • Seasons: Summer, Monsoon, Post-Monsoon, Winter

4. Climate Challenges for Architecture • High humidity • Heavy rainfall • Heat and thermal gain • Need for ventilation and moisture resistance

5. Key Features of Vernacular Architecture • Sloped clay tile roofs • Raised plinths • Open verandas • Courtyards for ventilation • Locally available materials

6. Roof Design • Steep slopes to drain rainwater • Overhangs to protect walls • Clay tiles for insulation and water resistance

7. Courtyards and Ventilation • Nalukettu layout with central courtyard • Promotes airflow and light • Reduces humidity and heat buildup

8. Materials and Construction • Laterite stone: thermal insulation • Timber: seasoned for moisture resistance • Lime plaster: breathable, mold-resistant • Clay tiles: durable, thermally insulating

9. Orientation and Planning • East-west orientation reduces solar gain • Thick walls, small west windows • Large openings and verandahs on east/north

10. Examples of Vernacular Structures • Chendamangalam Synagogue • Tharavads (ancestral homes) • Fort Kochi houses • Kerala-style temples

11. Lessons for Modern Architecture • Passive cooling techniques • Climate-responsive design • Sustainable, low-impact practices • Local material use

12. Conclusion Cochin’s climate significantly shaped its architectural heritage. Traditional methods offer valuable insights for sustainable, climate-responsive design.
