India is set to introduce pioneering AC temperature rules, mandating that air conditioners cannot cool below 20°C or heat above 28°C. Announced by Union Minister Manohar Lal Khattar, this nationwide mandate aims to normalize cooling habits and significantly reduce energy consumption.
🔍 What the New Rule Entails
- Minimum 20°C and Maximum 28°C: ACs in homes, offices, hotels, malls, and even vehicles must adhere to this range. Units below or above this will be disallowed.
- Applies to New ACs: All new units sold in India will have firmware locks enforcing this range.
- Cross-Sector Scope: Residential, commercial, and transport sectors are covered in this first-of-its-kind pilot.
✅ 5 Key Impacts of the Policy
1. ⚡ Major Energy Savings
Every 1°C increase in temperature can save up to 6% in energy. Enforcing 20–28°C could lead to ₹18,000–20,000 crore in consumer savings over three years.
2. 🔥 Reducing Peak Power Strain
ACs contribute heavily to peak demand (~50 GW). Standardizing settings eases grid load, helping prevent summer blackouts.
3. 🌍 Environmental & Emission Benefits
By limiting excessive cooling, the policy lowers electricity usage and carbon emissions—aligning with India’s climate goals.
4. 🧘 Health-friendly Comfort
Experts recommend 22–24°C—within the mandated range—to prevent thermal shock and health problems when moving between indoors and outdoor heat.
5. 🚦 Global Leadership
India’s law exceeds average global mandates (like Italy and Spain’s 25–27°C range) by legally enforcing this across households and vehicles.
🇮🇳 Why It’s a Big Deal
- First-of-its-kind experiment: The law will pilot cross-sector regulation, not just public buildings.
- Manufacturing oversight: AC producers will embed temperature locks into devices, with firmware enforced compliance.
- Public involvement: The Bureau of Energy Efficiency (BEE) consulted stakeholders—including industry, consumers, and automakers—to shape the rule.
🕒 Timeline & Next Steps
- Guidelines and firmware updates are being finalized with manufacturers and ministries.
- Implementation pilot to launch soon, beginning with public sector buildings and new AC models.
- Scale-up expected across broader sectors—as the policy matures.
