IHG (InterContinental Hotels Group) desempeña un papel importante en el camino hacia la sostenibilidad del sector hotelero, con más de 5.500 hoteles en 15 marcas en casi 100 países de todo el mundo. A través del sistema IHG Green Engage, IHG ha reducido su huella de carbono por habitación ocupada en un 15% entre 2013-2017. Un área clave de enfoque en la reducción del consumo de energía son los sistemas de calefacción, climatización y acondicionamiento de aire, que pueden llegar a utilizar entre el 60% y el IHG (InterContinental Hotels Group) plays an important role in the drive for sustainability in the hotel sector, with more than 5,500 hotels across 15 brands in nearly 100 countries around the world. Through the IHG Green Engage system, IHG has reduced its carbon footprint per occupied room by 15% between 2013 and 2017. A key area of focus in energy reduction is the HVAC systems that can use between 60% and 80% of all the energy consumed by a hotel. The InterContinental Madrid is an important success in the IHG Green Engage system. Located on the Paseo de la Castellana, the fivestar hotel has stood as a landmark in Spain’s hospitality industry throughout its 65-year history. It welcomes around 100,000 guests a year including presidents, royalty, celebrities and business leaders. A detailed energy survey conducted in 2016 by Exel Industrial, ABB’s official provider for sales, support, service and engineering in Madrid, revealed that the hotel’s energy use was high. In particular, the survey showed that the consumption was especially high in the eight groups of pumps that serve the HVAC systems as well as the hot water supply for the guest rooms, kitchens and other facilities. During a site visit, Exel Industrial noted that by reducing the motors’ speed by 10%, a saving in energy consumption of up to 40% could be achieved. 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 can be adjusted to match the precise demand at any given time. ABB’s intelligent motion solutions enable energy savings of around 40%, helping InterContinental Madrid to not only to meet, but exceed, its IHG Green Engage system goals. Over a year, this saving adds up to a total of 445,000 kWh, cutting the hotel’s annual EL HOTEL INTERCONTINENTAL MADRID REDUCE EN UN 40% SU CONSUMO ENERGÉTICO Una investigación publicada por el International Tourism Partnership (ITP) muestra que la industria hotelera representa actualmente el 1% de las emisiones mundiales. Esta cifra aumentará a medida que el turismo continúe en auge, ya que el número total de habitaciones de hotel en todo el mundo aumentará de 17,5 millones a más de 25 millones para 2050. El sector hotelero necesita conocer y reducir su impacto climático, y en esta línea trabajan muchas de las grandes cadenas hoteleras, como es el caso de Intercontinental Hotels Group, a través de su programa IHG Green Engage. En el marco de este programa el hotel InterContinental Madrid ha logrado reducir su consumo energético en 445.000 kWh al año, gracias a los convertidores y motores de alta eficiencia de ABB. THE INTERCONTINENTAL MADRID HOTEL CUTS ITS ENERGY USAGE BY 40% 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 over 25 million by 2050. The hotel sector needs to understand and reduce its environmental impact and many of the large hotel chains are working towards this goal, such as the InterContinental Hotels Group, through its IHG Green Engage programme.Within the framework of this system, the InterContinental Madrid hotel has managed to reduce its energy usage to 445,000 kWh, thanks to drives and high-efficiency motors from ABB.
