Restricting AC Temperature: A Climate-Smart and Health-Safe Cooling Strategy

Syllabus: Energy

 

Context:

  • The Union Ministry of Power has proposed a mandatory operational temperature range of 20°C to 28°C for all new air conditioners used in residential, commercial, and vehicular settings. This marks a significant policy evolution from the 2018 advisory of a default 24°C setting, transitioning from voluntary compliance to enforced manufacturing norms.

Why the Reform Is Necessary

  • Mounting Energy Demand from Cooling
  • Rising Load Projection: India’s cooling demand is projected to reach 200 GW by 2030, placing immense stress on the national grid.
  • Current Burden: ACs already contribute 50 GW, nearly 20% of peak power demand, despite only 6% household penetration, indicating unsustainable growth ahead.

 

Economic Implications

  • Electricity Tariffs: Escalating demand could necessitate tariff hikes and increased fossil-fuel-based generation, disproportionately affecting lower-income households.
  • Energy Equity: Demand moderation ensures affordable and inclusive access to electricity, preserving socioeconomic balance.

 

Health Hazards of Overcooling (<18°C)

  • Cardiovascular Stress: Indoor temperatures below 18°C cause vasoconstriction, increasing blood pressure by 6–8 mmHg, elevating hypertension risk.
  • Respiratory Risks in Children: Prolonged exposure to ~16°C has been associated with reduced lung capacity and airway resistance in young children.
  • Mental Health Deterioration: Cold indoor environments correlate with depression, anxiety, and stress, as observed in studies from temperate regions like the UK.
  • Disrupted Sleep & Immunity: Overcooling adversely affects sleep cycles, weakens immune function, and impairs cognitive performance.
  • Thermal Vulnerability: Elderly and infants, with diminished thermoregulatory efficiency, are more prone to cold-induced morbidity.

 

Benefits of the Proposed Temperature Regulation

  • Energy Efficiency
  • Each 1°C increase in AC temperature can result in 6% energy savings.
  • Cumulative savings could reach 20 billion units annually, easing grid pressure during peak demand.

 

Climate Impact Mitigation

  • Reduces CO₂ emissions, supporting India’s net-zero pathway and Paris Agreement commitments.
  • Enhances compliance with SDG 13 (Climate Action).
  • Health-Conscious Cooling
  • Promotes thermal comfort without compromising physiological or mental health.
  • Helps normalize moderate cooling as a social and behavioral standard.
  • Infrastructure Resilience
  • Helps avoid blackouts, reduces reliance on emergency fossil-fuel generation, and curbs long-term infrastructure costs.

 

Alignment with National and Global Frameworks

  • India Cooling Action Plan (ICAP): Reinforces the ICAP target to reduce cooling energy demand by 25–30% by 2038.
  • Global Best Practices: Mirrors Japan’s 28°C default, aligning India with international climate-smart standards.
  • Smart Cities & Urban Sustainability: Facilitates climate-resilient urban planning, sustainable architecture, and eco-sensitive infrastructure.

 

Conclusion

  • The Ministry’s proposal to mandate a standardized AC temperature range represents a scientifically grounded, eco-conscious, and public health-sensitive regulatory reform. It not only aligns with India’s climate and energy goals but also cultivates responsible consumption behavior. By addressing both infrastructural stress and individual well-being, the initiative marks a decisive step toward sustainable urban living and intergenerational equity in the Anthropocene era.

Consider the following statements regarding the Union Ministry of Power’s proposal to regulate air conditioner temperature settings in India:

  1. The proposal seeks to make 24°C the maximum allowable temperature setting for all new air conditioners sold in
  2. The move aims to reduce India’s cooling energy demand in line with the objectives of the India Cooling Action Plan (ICAP).
  3. Japan’s “Cool Biz” campaign has influenced India’s push towards a behavioral shift in indoor thermal comfort norms.

Which of the statements given above is/are correct?

A. 1 only
B. 2 and 3 only
C. 1 and 2 only
D. 1, 2, and 3

Correct Answer: B. 2 and 3 only

Detailed Explanation:

  • Statement 1: Incorrect
  • Claim: The proposal seeks to make 24°C the maximum allowable temperature for ACs.
  • Reality: The Union Ministry of Power has proposed a mandatory operational temperature range of 20°C to 28°C for all new AC units, not a maximum of 24°C.
  • The key misinterpretation here is that 24°C is a maximum, when in fact:
  • 24°C was an advisory default setting in 2018 (voluntary).
  • Now, the proposed regulation is to hardwire all new ACs with a temperature operating range between 20°C (minimum) and 28°C (maximum).
  • This is aimed at limiting excessive cooling to save energy and avoid health hazards.

Statement 2: Correct

  • The regulation aligns directly with the India Cooling Action Plan (ICAP), which aims to:
  • Reduce cooling energy demand by 25–30% by 2038.
  • Promote sustainable and climate-smart cooling solutions.
  • Enhance energy efficiency and reduce greenhouse gas emissions from refrigeration and AC use.
  • Controlling default temperature settings in ACs directly contributes to these ICAP targets by:
  • Reducing electricity consumption.
  • Minimizing peak demand on power grids.

 

Statement 3: Correct

  • The “Cool Biz” campaign launched by Japan in 2005:
  • Encouraged government offices and businesses to set ACs to 28°C.
  • Promoted lighter dress codes and behavioral adaptation to reduce energy use.
  • India has drawn inspiration from this global practice to create behavioral norms and public awareness about energy-conscious cooling habits.
  • This approach is being incorporated into regulatory norms, not just public campaigns, in India.

Conclusion:

  • Statement 1 is incorrect: Misrepresents the policy — 24°C is not the cap; it’s about a 20–28°C operating range.
  • Statements 2 and 3 are correct: The policy aligns with ICAP and reflects lessons from international best practices like Japan’s Cool Biz.

DNA Identification Techniques

Syllabus:Science and Technology

Context:

  • Following the Air India Boeing 787 crash in Ahmedabad, authorities have turned to DNA identification to ascertain the identities of the deceased victims.

 

What is DNA Identification?

  • DNA identification is a forensic method used to match DNA from human remains with known samples to confirm identity.
  • Each individual (except identical twins) has unique DNA, making it an effective biological fingerprint.
  • Widely used in mass disasters, aviation accidents, war zones, and criminal investigations.

 

 

How It Works

  1. Sample Collection & Preservation
  • Sources: Hard tissues (bones, teeth) or soft tissues (skin, muscle).
  • Preservation: Stored in ethanol or frozen at –20°C to prevent degradation, especially crucial in hot/humid conditions.
  1. Reference DNA

Obtained from:

  • Biological relatives (parents, children, siblings).
  • Personal items (e.g., toothbrushes, hairbrushes).
  • Used for comparison and confirmation.

 

DNA Analysis Methods

Technique

Use Case

Notes

STR (Short Tandem Repeat)

Most common for nuclear DNA

High accuracy; ideal for preserved samples

mtDNA (Mitochondrial DNA)

When nuclear DNA is degraded

Inherited maternally; matches maternal relatives

Y-STR Analysis

Traces paternal lineage (males)

Used when maternal relatives are unavailable

SNP (Single Nucleotide Polymorphism)

Extremely degraded DNA

Less precise, but useful with minimal reference data

 

Key Features & Applications

  • Gold Standard: Globally adopted for victim identification in mass casualty incidents.
  • Precision: Capable of identifying individuals from even highly degraded remains.
  • Storage-Sensitive: Requires careful handling to preserve data integrity.
  • International Practice: Used by CBI, Interpol, and ICRC.
  • Legal Standing: DNA evidence is admissible in Indian courts under the Indian Evidence Act.

With reference to forensic DNA identification techniques used in mass disasters and aviation accidents, consider the following statements:

  1. Short Tandem Repeat (STR) analysis can be used even when DNA is highly degraded due to environmental exposure.
  2. Mitochondrial DNA (mtDNA) analysis is preferred in cases where reference DNA is available only from paternal relatives.
  3. Y-chromosome STR analysis is ineffective in identifying female victims.
  4. DNA evidence obtained from personal items like toothbrushes is not legally admissible in Indian courts.

Which of the statements given above is/are correct?

A. 1 and 4 only
B. 2 and 3 only
C. 3 only
D. 1, 2, and 4 only

 

Answer: C. 3 only

Explanation:

  • Statement 1 – Incorrect:STR analysis requires relatively intact nuclear DNA. It is not suitable when DNA is severely degraded due to heat, moisture, or time. In such cases, mtDNA or SNP analysis is used.
  • Statement 2 – Incorrect: mtDNA is inherited maternally, not paternally. If only paternal relatives are available, Y-STR (for males) may be used, not mtDNA.
  • Statement 3 – Correct:Y-STR analysis traces male lineage (Y chromosome is present only in males). Thus, it is not applicable to identify female victims.
  • Statement 4 – Incorrect:DNA obtained from personal items like toothbrushes, razors, or hairbrushes is legally admissible in Indian courts under the Indian Evidence Act, provided chain of custody is established.
