Personal Hurricane Experience in Barbados
- Childhood memories: annual hurricane season preparations
- Duct-taping glass doors in X patterns
- Boarding up windows (leaving 1-2 open to "let wind come through")
- Placing buckets in living room to catch rain from sagging roof
- Fear of tropical waves, thunderstorms, hurricanes
- Basic survival conditions: no light, water, electricity - only battery radio for "all clear"
- Childhood question: why not build safer structures if storms happen annually?
Current Climate Crisis Reality
- Adult fears matching childhood experiences due to climate change
- Recent freak storms in Barbados unlike anything seen before
- Specific storm event: 500 lightning strikes per minute, no advance warning
- Category 1 hurricane weeks later destroyed 2,000+ homes
- Barbados context: <300,000 people, 166 square miles - small events = big losses
- Need for architecture that "genuinely performs" vs. "beautifully passive"
Professional Approach to Climate-Resilient Design
- Speaker: architectural designer creating nature-aware protective structures
- Philosophy: harness and embrace nature rather than fight it
- Drawing on traditional micro lessons from community experience
- Focus on inherent resilience stories from local context
Historical Context: Bajan Chattel Houses
- Post-slavery era (after abolition of African/Indigenous enslavement)
- Newly freed people couldn't own land - still "chattel" of former enslavers
- Solution: portable timber homes with no nails, on coral stone foundations
- Requirements: robust enough for tropical weather, temporary for quick relocation
- Survival strategy when disputes arose with former enslavers
Traditional Design Principles
- Materials: readily available timber, no proprietary systems
- Strategy: work with wind instead of against it
- Key feature: jalousie windows (from French "jalousie" = jealousy)
- Originally designed to prevent peering eyes
- Angled horizontal slats (louvers) filter wind while keeping rain out
- Wind management: intentionally aligned apertures allow hurricane passage through interior
- Result: prevents destructive pressure buildup on facade
- Outcome: houses "might bend but wouldn't totally break"
Modern Applications of Traditional Principles
- Regional departure from global convention of closing buildings off from nature
- Focus on holistic performance with environment vs. external aesthetics
- Emphasis on micro solutions and details that "make or break" buildings
Post-Hurricane Maria (2017) Reconstruction
- Common question: "How do we build back better?"
- Methodology: take what works, discard what doesn't, apply to modern designs
- Modern timber fin facade interpretation:
- Breaks up wind against building exterior
- Allows light penetration to interior
- Protects glass from wind and wind-driven missiles
- Eliminates need for duct tape
- Sacrificial central core design:
- Allows wind penetration through building interior
- Preserves adjacent watertight bunker zones for human retreat
- Eliminates need for buckets
Broader Climate Resilience Applications
- Colleagues in island nations integrating similar traditional-to-modern strategies
- Applications beyond hurricanes: floods, earthquakes, landslides
- Stilted designs: elevation above torrential downpour and inundation
- Cross-brace lattice elements: flexibility for earth movement/shaking
Digital Design and Testing Methods
- Intelligent digital twin modeling in virtual reality
- 3D computerized carbon copy of each micro solution
- Stress-testing capabilities with real-world climate scenarios
- Virtual environment benefits: no human life loss, no infrastructure damage
- Iterative design process: test, fail, fix, tweak, improve, optimize
- Example: Category 5 hurricane wind simulation testing
- Starting from Indigenous references = accessible, culturally appropriate architecture
Psychological Impact of Hurricane Experience
- Mental uncertainty of experiencing/surviving hurricanes
- Total vulnerability and exposure to elements
- Sounds: wind ripping buildings apart, neighbors' screams carried by wind
- "What if?" scenarios: survival uncertainty for self, neighbors, community
- Vision: designing away uncertainty, sheltering with confidence
- Goal: best chance at surviving and weathering storms
Global Context and Urgency
- Contrast: humans putting people in space for leisure vs. constant climate fear
- Exploring survival in distant planetary climates vs. Earth-based climate threats
- Small island nations living in present what others will face in future
- Immediate need to know what works/doesn't work in specific contexts
- "True, immediate, cyclical matter of life and death"
Call to Action for Future Design
- Approach for designing future cities and communities
- Stop leaving vulnerable populations to "guess and hope for the best"
- Base designs on tried, tested, traditional knowledge and lived experience
- Design for "absolute worst" scenarios
