Concept:
ECBC is an important regulatory framework in India aimed at improving the energy efficiency of buildings and reducing overall energy consumption.
Explanation:
ECBC stands for Energy Conservation Building Code.
It was developed by the Bureau of Energy Efficiency (BEE) under the Ministry of Power, Government of India.
ECBC sets minimum energy performance standards for:
Building envelope (walls, roofs, windows),
Lighting systems,
HVAC (heating, ventilation, and air conditioning),
Electrical systems.
The objective of ECBC is to reduce energy demand without compromising occupant comfort.
The other options are incorrect because:
ECBC focuses on energy conservation, not electricity consumption alone,
It is not related to energy conversion.
Conclusion:
Hence, ECBC correctly expands to Energy Conservation Building Code.
Final Answer: \(\boxed{\text{Energy Conservation Building Code}}\)
