HeatAware SG
HeatAware SG is Singapore's first community initiative designed to raise heat awareness among seniors aged 50 and above, protecting the elderly from rising heat risks. Through household interviews, the team assesses residents' heat-awareness knowledge and deploys sensors to monitor indoor temperatures. Based on this data, they provide individualised cooling strategies to help vulnerable residents protect themselves.
Two study phases were conducted:
Conduct 1: Heat Awareness Surveys — 201 residents aged 50+ were surveyed at Repair Kopitiam meetups across 11 locations about their heat experience.
Conduct 2: Heat IoT Sensors Deployment — Temperature and humidity readings were captured across 3 rooms in 54 HDB households for 30 days.
Objectives
- Enhance heat risk awareness among vulnerable communities through participatory data collection
- Empower vulnerable residents with real-time, personalised heat alerts and actionable self-cooling guidance
- Generate granular household-level heat data to inform broader climate resilience strategies and urban cooling models
Report
Key Findings
Conduct 1
- 56% (112/201) of survey respondents have never heard of a heatwave
- 70% (141/201) of survey respondents are concerned about heat-health risks, yet few have taken action about them
Conduct 2
- 76% (41/54) homes averaged a warmer Heat Index indoors than outdoors
- A 7°C warmer Heat Index was recorded indoors than outside air overnight
