Energy conservation
The building receives 11 kV power from Tamil Nadu Electricity Board. The contracted demand is 1,300 kVA. The 11 kV supply is converted to 440 volts through two 1 mVA transformers. The average energy consumption is 9,000 (kWhr) units per day. Of the 9,000 units, two-thirds of the consumption is consumed by air-conditioning system. Both the main and the annexe buildings are fully air-conditioned. However, in the main building, which is more than 20 years old, energy conservation efforts are not initiated.
