Chandigarh Administration Issues Advisory On Optimum AC Temperature

In a major step towards strengthening energy efficiency and sustainable resource management, the Chandigarh Administration has issued advisory cum guidelines promoting optimum temperature settings of 24-25°C in air-conditioned buildings across the Union Territory. The initiative is being undertaken by the Energy Management Cell (EMC)/State Designated Agency (SDA), Engineering Department, UT Chandigarh, the nodal agency for promoting and implementing energy efficiency measures in Chandigarh. The advisory has been issued in accordance with the Energy Conservation Act, 2001, and the guidelines of the Bureau of Energy Efficiency (BEE), Ministry of Power, Government of India. With the building sector accounting for more than 30% of India’s total electricity consumption and space cooling representing a significant portion of this demand, the Administration has emphasized the urgent need for responsible cooling practices.

According to BEE estimates, every 1°C increase in air-conditioner temperature can result in approximately 6% energy savings. Since most cooling systems are typically operated at 20-21°C, raising the temperature to the recommended 24-25°C range can potentially reduce electricity consumption by nearly 24%, without compromising occupant comfort when supported by proper humidity control and airflow.

These guidelines are applicable to Government Departments, Educational Institutions, Boards, Corporations, commercial establishments, and large buildings such as airports, hotels, shopping malls, offices, and government facilities. Personnel responsible for operation and maintenance of cooling systems are advised to ensure compliance while maintaining comfortable indoor conditions.

Special exemptions have been provided for facilities requiring specific ambient conditions, including healthcare institutions, operation theatres, food processing units, and data centers.

Through this proactive initiative, Chandigarh Administration reaffirms its commitment to promoting energy conservation, reducing carbon emissions, lowering electricity demand, and creating a more sustainable and climate-resilient urban environment.
