WP Kenneth Tiong want Aircon in school to filter out haze.
@Babe:Aircon. don't filter out haze.
As MP get your facts right.
Only air purifier with HEPA filter H13 or higher is effective.
@Babe:Also, multi millions or billions $ need to set aside to install all aircons in schools.
Energy prices soaring.
Is WP funding this Aircon project that cannot filter out haze?
@Babe:Did WP work out the amount to be deployed in few hundred schools, JCs?
1. Deploy standalone aircon units in every classrooms in each schools?
2. Or install DCS (District Cooling Systems) and pipe into every classrooms?
3. How much energy electricity prices to set aside per month per school?
WP paying for all these?

AI Overview
All Singapore classrooms will be outfitted with additional and more powerful fans by 2027 as part of the Ministry of Education's (MOE) updated thermal comfort strategies. Announced in March 2026, this nationwide initiative aims to combat rising ambient temperatures and protect student learning environments without heavily relying on energy-intensive air conditioning.
🌪️ Key Classroom Cooling Infrastructure Rollout
To mitigate the impact of heat on students, the government is combining advanced airflow technologies with passive cooling solutions:
- High-Efficiency DC Classroom Fans: Schools are progressively upgrading to more powerful, energy-efficient Direct Current (DC) fans to accelerate air velocity and promote evaporative cooling directly inside classrooms.
- High Volume Low Speed (HVLS) Fans: Large-scale "giant fans" are deployed in multi-purpose halls, indoor sports facilities, and school common areas to handle massive air distribution quietly and effectively.
- Cool Paint Building Coatings: The exterior facades of school buildings are being coated with heat-reflective cool paint to drastically lower heat absorption by the structures.
📊 The Science Behind the Upgrade
The decision to heavily boost classroom air velocity stems from a 2024 National University of Singapore (NUS) study commissioned by the MOE. The research revealed that secondary school students experience significant drops in cognitive performance—decreasing by 9.2% in slightly warm conditions and up to 18.1% in warm conditions—when adequate airflow is absent. Elevating air velocity via powerful fans successfully maintains a neutral thermal comfort level for students up to a room threshold of 30°C.
🛑 Exceptions and Targeted Air-Conditioning
While the default standard relies on optimized natural cross-ventilation, shading, and powerful fans, the MOE provides localized interventions for vulnerable schools:
- Dust & Noise Insulation: Air-conditioning will be considered for specific classrooms that must remain enclosed for extended periods due to persistent construction noise or high dust levels.
- Mixed-Mode Cooling: The government is testing hybrid systems that mix elevated air speeds from ceiling fans with moderate air-conditioning baselines to balance student comfort with strict energy-efficiency goals.
