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
