Mili Majumdar heads sustainable habitat division at The Energy and Resources Institute (TERI) in Delhi. She is an expert on energy efficiency.

She spoke to HT on the massive wastage of electricity in Delhi’s hotels and malls and ways to curb it.

Is there an estimate to the power wasted by Delhi’s shopping and five-star hotels?
The wastage is massive. We can bring down the consumption by as much as 50% in new buildings. Even in existing buildings, the consumption can be brought down by 20-30%.

We recently did extensive work on five-star hotels and were surprised to see the amount of energy they waste. Malls have generally not been covered, but we’re working on it.

How do we cut down on the wastage?
There is overcooling everywhere, even in unoccupied areas. The idea is to keep the temperature at 25-26 degrees Celsius, which is comfortable. But they always cool it down to 20 degrees Celsius or below.

What’s the way forward?
We cannot shut down malls, multiplexes or hotels. The idea is to ensure energy efficiency without compromising on the quality of life.

All showcases in malls are leak away the cooling. The construction of these buildings and operations are faulty. We must fine-tune energy parameters. Mandatory energy audits seldom happen.

The mandatory provisions such as solar panels are not followed in most cases.
Solar panels and other similar measures are add-ons. Who’s going to maintain them? They will be effective only when we plug major leaks.
