KKN Gurugram Desk | As the summer heat continues to intensify across the country, India is taking proactive measures to address energy conservation and environmental sustainability. In a bid to curb energy wastage and reduce the excessive demand for electricity during peak summer months, the Indian government is planning to implement a new AC temperature regulation in line with global practices. The new standard proposes that air conditioners (ACs) should be set to a temperature range of 20-28°C, with the rule potentially being enforced in government offices from 2025-2026.

This article explores the proposed changes in India’s AC temperature norms, how they compare with international regulations, and the impact of such measures on energy conservation and climate change.

Global AC Temperature Norms: A Look at International Standards

Countries around the world have already adopted various temperature regulations to combat rising energy consumption and environmental concerns. These measures aim to balance comfort with energy efficiency, and many of them have been in place for years. Here’s a look at some of the top countries with strict AC temperature limits:

Japan: The Pioneer in Energy Conservation

Japan has long been at the forefront of energy conservation policies. The country’s standard for air conditioning is set at 28°C for both residential and commercial buildings. This policy aligns with Japan’s national priorities of reducing electricity consumption and promoting energy-efficient technologies. The 28°C setting is enforced in public and government buildings, especially during the summer months, as part of Japan’s broader strategy to minimize its carbon footprint.

Italy: Focus on Reducing Carbon Emissions

Italy has also implemented stringent AC regulations to reduce carbon emissions. Public buildings in the country are required to maintain 25°C as the minimum temperature for air conditioning. This is part of Italy’s government initiative, Operation Thermostat, which limits both cooling and heating systems to help conserve energy. The initiative has significantly reduced energy wastage in public infrastructure.

Spain: Tackling Energy Crisis with AC Regulation

Spain introduced a law in 2022 that sets the minimum air conditioning temperature at 27°C during the summer. This regulation was implemented in response to the rising energy costs and the ongoing energy crisis. The policy is part of a broader effort to reduce electricity demand and greenhouse gas emissions, helping the country move towards a more sustainable energy future.

Belgium: Strict Indoor Climate Rules

Similar to Italy and Spain, Belgium enforces regulations for indoor climate control. During summer, air conditioning in public buildings must be set at 27°C. In winter, heating is capped at 19°C. These measures are part of Belgium’s legal framework to improve energy efficiency in public buildings and promote sustainable energy use.

United Kingdom: Ideal AC Setting of 24°C

In the United Kingdom, institutions like the London School of Economics advocate for setting AC temperatures at around 24°C, though this is not legally mandated. The UK focuses on energy-efficient practices, particularly in educational and governmental buildings, as part of their broader environmental policies.

United States: Energy Star Recommendations

In the United States, California enforces a minimum AC temperature of 25.6°C during the summer months. While this is not a legal requirement nationwide, the Energy Star program recommends setting air conditioners at 25.5°C (78°F) in homes to conserve energy. Institutions like Harvard University have also adopted similar temperature settings for energy conservation.

Singapore: Tropical Climate and Energy Efficiency

In Singapore, the tropical climate has led to the establishment of AC temperature norms between 24-26°C for public buildings. Additionally, the “Go 25” initiative encourages homes and businesses to increase their indoor temperature to 25°C or higher. The goal is to reduce energy consumption and promote sustainable cooling practices in both residential and commercial spaces.

Australia: Guidelines for Sustainable Cooling

While Australia does not have strict AC temperature regulations, the government recommends setting temperatures between 23-25°C for energy efficiency. Australia’s Minimum Energy Performance Standards (MEPS) ensure that only energy-efficient AC units are sold in the country. These guidelines promote responsible energy consumption without imposing a mandatory national temperature setting.

China: Mandatory 26°C for Government Buildings

In China, public and governmental buildings are required to maintain an AC temperature of 26°C or higher during the summer months. This regulation is aimed at reducing the strain on energy resources and ensuring energy efficiency in the public sector. The initiative is part of China’s broader commitment to energy conservation and sustainable development.

South Korea: Encouraging Energy Conservation

South Korea has implemented a policy that encourages setting AC temperatures at 26°C during the summer. The government recommends this temperature for both public offices and homes to promote energy conservation and reduce environmental impact.

India’s Proposed AC Temperature Regulation

India, like many other countries, is grappling with the challenges of climate change and rising electricity consumption. As a step toward reducing energy wastage, the Indian government has proposed a new standard for air conditioning temperatures in public offices and government buildings. According to the new proposal, the minimum temperature range for ACs will be set between 20-28°C.

This regulation is currently in the trial phase and is expected to be implemented by 2025-2026. The new AC temperature norms are expected to have a significant impact on energy conservation, especially in the government sector, where large numbers of air-conditioned buildings consume substantial amounts of electricity.

Why is India Introducing This Regulation?

India has experienced extreme heatwaves in recent years, with 2024 being recorded as one of the hottest years in history. Cities like Jaipur, Delhi, and Jaisalmer have seen temperatures soaring above 48°C, putting immense pressure on the power grid. With rising temperatures and electricity demands, the need for energy-efficient practices is more urgent than ever.

The proposed AC temperature standard aims to strike a balance between comfort and energy efficiency. By regulating the temperature of air conditioners, the government hopes to reduce overall electricity consumption and promote responsible energy usage. Additionally, the initiative aligns with global efforts to combat climate change and reduce carbon footprints.

Impact on Public and Private Sectors

The new temperature guidelines will primarily apply to government offices and public buildings, with a gradual rollout in the private sector. While these measures will help reduce energy consumption in the public sector, the private sector is also encouraged to adopt similar standards to promote sustainable practices.

India’s proposal for AC temperature regulation is a timely move in the wake of rising temperatures and energy demands. By aligning with global standards set by countries like Japan, Italy, and Spain, India is taking a step towards a more sustainable future. This regulation will not only contribute to energy conservation but also help the country meet its climate goals.

As the trial phase progresses, it is expected that more government buildings and private institutions will adopt similar measures to create a more energy-efficient and environmentally conscious society. The success of this initiative could pave the way for further regulations that promote responsible energy consumption across the nation.
