Worsening Air Quality Adds Cost to Hotels

The alarming levels of smog and pollution in Delhi/NCR (reaching 30 times the WHO’s safe limits) had dented travel plans of several domestic and overseas travellers in the busiest tourist season for the Indian capital where winter has just set in. Environmental authorities had imposed severe plus category restrictions earlier this month while the doctors had declared it a public health emergency.

Taj Hotels Palaces Resorts Safaris, which runs hotels like the Taj Mahal Hotel and Taj Diplomatic Enclave in New Delhi, said it is also putting in additional efforts to monitor and enhance the air quality in its guest rooms.

At the Taj Mahal Hotel, New Delhi, outdoor air intake is being controlled mechanically. The air is filtered through high efficiency filters before being distributed around the building. In addition, carbon dioxide (CO2) levels are being monitored and maintained at less than 1,000 ppm (parts per million), while adequate air changes per hour (ACH) 6-15 are also maintained throughout the hotel as per ASHRAE guidelines, a ventilation benchmark for acceptable indoor air quality.

Cost Implication on Frequency of Cleaning

At Taj Diplomatic Enclave, all the treated fresh air and the air handling units, which condition the air in all guest rooms and public areas, are installed with dust-free filters, which weed out the suspended particle PM 2.5 and PM 10 with the efficiency of up to 70%, the spokesperson said. Aseem Kapoor, general manager at Hyatt Regency Delhi, said to address the current needs, the frequency of the filter cleaning has been increased in the past two weeks to almost daily/weekly at the hotel.

Buying Extra Air Purifiers

The otherwise regular filter cleaning schedule for Hyatt Regency Delhi is monthly for room AC filters, and 7-10 days and 15 days for restaurants and fitness centres, respectively. “Four additional air purifiers have been installed in the fitness centre to avoid dust, the landscaped grounds are being watered twice a day and fresh air intake to the building is being kept down to the minimum.”
