Energy Use Intensity (EUI) reflects a rate of energy use and is a
type of energy benchmark that is widely used in building energy
analysis particularly for commercial buildings. Such EUIs have been
used in several energy benchmarking studies for commercial buildings
[e.g., 16–19]. The Bureau of Energy Efficiency set up by the
Government of India under the provisions of the Energy Conservation
Act 2001, is entrusted with the task of developing specific
energy conservation building codes. Benchmarking energy efficiency
of different building types has been initiated and the Bureau
has recently developed a Star Rating for BPO buildings in various
climatic zones in India. The Bureau uses the Energy Performance
