Efforts by Shangri-La Hotels have resulted to 6.7 kg Carbon Dioxide (CO²) saved for every available room night operated.
Since the late 1990s, the Shangri La Hotels and Resorts Group has embarked on a large scale energy-saving program. Air condition is targeted in priority with the upgrading of hotels central chillers. Inefficient chillers are replaced with highly efficient units that use environmentally friendly HCFC° refrigerant. The energy savings can be estimated are 30-40 percent over the previous units. Over 14,000 tons of refrigeration units have been replaced with an annual savings of over 2 million kilowatt-hour (kWh). Already upgraded are Shangri La hotels in Bangkok, Cebu, Kuala Lumpur, Manila (two properties), Shenzen and Singapore. New hotels are also equipped with new efficient chillers units running below 0.58 kW/ton.
Over 50 percent of hotel boilers now use natural gas as a fuel source. They are cleaner (lower CO2 and pollutants discharge) and more efficient than diesel oil. All hotels are also fitted with variable speed drives for air handling units, pumps and fans to vary and reduce energy use; public areas are lighted with incandescent lamps, back offices with fluorescent lamps, ballrooms and function rooms fitted with low energy lamps for events set-up and guestrooms have on average 50 percent of its lighting provided by energy-savings lamps; water saving devices are installed in guestrooms to allow flow standards of 6,12 and 18 liters per minute for basin taps, shower heads and bathtub spouts respectively; electric, water, gas meters and sub-meters are installed in profit and cost centers to monitor and benchmark individual consumption.
The group conducts regular inspections to monitor compliance according to its Energy Conservation Best Practices Program implemented. Twenty-three hotels are already certified ISO 14001, an environment certification program. This program includes energy management, waste disposal, recycling and the elimination of ozone layer depletion gasses. Further reduction of energy consumption will be reached through the use of new technologies, alternative energy sources and the development of more efficient buildings.
Results show that the group will reduce by 12 percent its 2007 electrical consumption over 2006. It is expected to achievement a 6.7 kg CO2 reduction for every available room night operated. In 2006 estimated CO2 emission by Shangri-La hotels stood at 390,000 metricTons.
