In a recent Guideline dated 25th June, 2018, the Bureau of Energy Efficiency, (“BEE”) has recommended all consumers of commercial buildings to maintain the internal temperature between 24-25 degree Celsius with appropriate humidity and airflow to conserve energy, subject to operational and functional requirement.
Background:
Typically, room temperature is set between 20-21 degree Celsius whereas, as per the comfort chart, it is suggested that ideal temperature could be maintained around 24-25 degree Celsius. Considering change from 20 degree Celsius to 24 degree Celsius, there exists potential to increase at least 4 degree Celsius, which may lead to savings of about 24% of electricity consumption. Annually, this may translate to saving potential of about 20 billion units of electricity, by taking simple measures like adjusting the temperature setting of AC system to 24 degree Celsius.
Applicability:
These guidelines are mostly applicable for large premises such as Airports, Hotels, Shopping Malls, Offices and Government Buildings (Ministries & attached offices, State Government, and Public Sector Undertakings), having huge potential for savings.
Exclusion:
These guidelines may not be applicable for premises where specific ambient conditions are required e.g. health care facilities/operation theatre / Food processing installations / Data Centers, etc.
Key Highlights of the Guidelines:
The BEE recommends the following to the consumers:
- All consumers of commercial buildings are suggested to maintain the internal temperature between 24-250C with appropriate humidity and airflow to conserve energy and for the health benefits of occupants, subject to operational and functional requirement.
- Personnel responsible for operation and maintenance of air conditioning/cooling system may be suitably counseled to maintain such parameters without adversely affecting the comfort conditions.
- The consumers may also take any other appropriate measures to save energy.
- Any deviation of such Guidelines should normally be considered with the approval of head of the organization.
- The above suggestions are not applicable for winter climatic conditions.
