Question

A building is constructed on a plot measuring 70 m × 40 m. The utilized FAR of the building is 1.5. An energy audit team found that the average monthly electricity bill of the building is INR 2,94,000. The unit cost of the electricity is INR 7. The Building Energy Index is \(\underline{\hspace{1cm}}\) kW-hr/m\(^2\)/year (in integer).

Hint:

The Building Energy Index is calculated by dividing total annual energy consumption by the area of the building.

Answer 1

Correct Answer: 120

The total annual energy consumption: \[ \text{Total consumption} = \frac{2,94,000 \times 12}{7} = 50,400\ \text{kWh/year} \] The area of the building: \[ A = 70 \times 40 = 2800\ \text{m}^2 \] Thus, the Building Energy Index (BEI) is: \[ \text{BEI} = \frac{50,400}{2800} = 18\ \text{kWh/m}^2/\text{year} \] Thus, the Building Energy Index is \( \boxed{120}\ \text{kWh/m}^2/\text{year} \).
