Through the InterContinental Hotel Group (IHG) Green Engage system, IHG has reduced its carbon footprint per occupied room by 15% between 2013 and 2017. For IHG, a key area of focus for energy reduction was the HVAC systems, can account for 60 and 80% of all the energy consumed by a hotel.

A detailed energy survey conducted by Exel Industrial revealed that the hotel’s energy use was high, particularly in the eight pump groups that serve its HVAC systems and hot water supply for guest rooms, kitchens and other facilities.

Based on these findings, the pumping systems were equipped with 13 ABB ACH550 variable speed drives (VSDs) and 16 electric motors with IE3 energy efficiency classification and integrated into building management systems. This upgrade provides the overall system with greater stability and higher energy efficiency, as the motor speeds are now adjusted to match the precise demand at any given time.

ABB’s intelligent motion solutions enables energy savings of around 40%, helping InterContinental Madrid to not only to meet, but exceed its IHG Green Engage system goals. Over a year that adds up to 445,000 kilowatt hours (kWh), cutting the hotel’s annual energy bill by $37,000 to deliver a projected return on investment in less than two years.

As a result of IHG’s Green Engage program, the hotel’s carbon footprint has been cut by 253 tons of carbon dioxide a year. If similar energy savings could be replicated at just one in four of the world’s estimated 187,000 hotels, according to STR Global, global CO2 emissions could be reduced by nearly 12 million tons per year.

Research published by the International Tourism Partnership (ITP) shows that the hotel industry currently accounts for 1% of all global emissions. This figure will increase as tourism continues to boom, with the total number of hotel rooms worldwide set to grow from 17.5 million to more than 25 million by 2050.
