he was just another out of touch elitist boomer who was sorely out of touch with modern reality..
very short-sighted person, his failure to consider UHI in many towns in SG.
You’ve touched on a very real critique of Singapore’s urban planning legacy — the Urban Heat Island (UHI) effect.
What the UHI Effect Means
- The UHI effect occurs when built-up areas trap heat due to dense concrete, asphalt, and limited greenery.
- In Singapore, this manifests as higher night-time temperatures, reduced wind flow, and increased reliance on air-conditioning.
- Studies show that parts of Singapore can be 2–4°C hotter than surrounding rural or coastal areas because of this effect.
Liu Thai Ker’s Planning vs. UHI
- Liu Thai Ker’s housing and town planning emphasized high-density concrete blocks to maximize land use efficiency.
- While this solved the housing crisis and created integrated towns, critics argue it prioritized efficiency over environmental cooling.
- At the time (1970s–1990s), climate adaptation was not yet a mainstream planning concern, so UHI mitigation wasn’t central to his designs.
Later Corrective Measures
Singapore has since pivoted strongly to address UHI:
- Greenery integration: Vertical gardens, rooftop greenery, park connectors.
- Cooling urban design: Wider streets, ventilation corridors, reflective materials.
- Singapore Green Plan 2030: Explicit targets for tree planting and sustainable infrastructure.
- Nature-based solutions: Bishan-Ang Mo Kio Park’s river naturalization, Marina Barrage’s water catchment doubling as recreation.
Balanced Perspective
- Liu Thai Ker’s contribution was nation-building through housing — without his concrete-heavy approach, Singapore might not have solved its housing crisis.
- But yes, the environmental side effects (UHI, reduced biodiversity, heat stress) became apparent later, requiring new generations of planners to adapt.
- In hindsight, his work reflects the trade-off between urgent housing needs and long-term environmental sustainability.
Would you like me to map out how Singapore’s current cooling strategies (like tree canopy expansion and reflective materials) directly counteract the UHI effect created by earlier concrete-heavy planning? That would show how the city is actively correcting the imbalance left by Liu’s era.
