El hotel de lujo de negocios de Copenhague, el elegante Crowne Plaza Copenhagen Towers, en el distrito de Ørestad, ha sido diseñado desde cero con la sostenibilidad en mente. Sus consumos de electricidad y agua en 2015 fueron, respectivamente, un 77% y un 25% inferior a propiedades comparables en todo el mundo de la cadena Crowne Plaza. Estos resultados refuerzan el estatus del hotel como referencia mundial. Los envidiablemente bajos consumos de energía y agua se obtienen gracias a una sólida base de tecnología innovadora, a una operación basada en mejores prácticas, demostrada por la certificación ambiental ISO 14001 y el reconocimiento internacional con el premio de Turismo Sostenible (SKÅL) como el hotel más respetuoso con el medio ambiente del mundo. Innovador sistema de enfriamiento por agua subterránea Para que el consumo de energía y las emisiones de CO2 fueran lo más bajas posible, el hotel insistió en la tecnología energética de última generación. Una de sus características más significativas es un innovador sistema de enfriamiento por agua subterránea. Este sistema proporciona calefacción y aire acondicionado para 366 habitaciones, salas de conferencias, cocina, restaurante y oficinas en un ala contigua. Equipado con 2.500 m2 módulos solares El Crowne Plaza Copenhagen Towers también están equipadas con 2.500 m2 de módulos solares, especialmente adaptados, montados en tres de las cuatro fachadas del hotel, donde cubren parte de las Copenhagen’s luxury business hotel, the elegant Crowne Plaza Copenhagen Towers in the Ørestad district, has been designed from the ground up with sustainability in mind. Its electricity and water consumption for 2015 were respectively 77% and 25% lower than comparable properties worldwide in the Crowne Plaza chain. These results reinforce the hotel’s global benchmark status. The enviably lean power and water consumption are achieved on a solid base of innovative technology and best practice operation, demonstrated by ISO 14001 environmental certification and international recognition with a Sustainable Tourism (SKÅL) award, for the most environmentally friendly hotel in the world. Innovative ground water cooling system In order for energy consumption and CO2 emissions to be as low as possible, the hotel insisted on state-of-the-art energy technology throughout. One of its most significant features is an innovative ground water cooling system. This supplies the heating and air conditioning for 366 guest rooms, conference rooms, kitchen, restaurant and offices in an adjoining wing. Equipped with 2,500 m2 solar cell panels Copenhagen Towers is also equipped with 2,500 m2 specially adapted solar cell panels mounted on three of the hotel’s four façades, where they cover part of the building’s electricity requirements all year round. The installation constitutes Denmark’s largest array of solar cells, architecturally integrated into the building and which produce 200 MWh/year – equivalent to the electricity consumption of 65 average-sized detached houses. Both the ground water heating and cooling system and the solar cells are part of the foundation on which the hotel’s ‘green’ profile rests. To optimise energy efficiency and cost effectiveness, the systems are equipped with AC drives in the form of the VLT® HVAC Drive and Danfoss solar inverters. Ground water cooling and heat pumps save energy The ground water cooling system required two stages of drilling to a depth of 110 metres at two locations near the hotel. In the summer, cool water from the ground at 7- 9˚C, is pumped via one set of wells to the hotel’s cellars where it is sent through a heat exchanger and back down to a reservoir where the heat accumulates and is stored during the warmer months. The EL HOTEL DE LUJO DEL MAÑANA QUE ES IMPULSADO POR ACCIONAMIENTOS Diseñado para la sostenibilidad, el Crowne Plaza Copenhagen Towers es un verdadero ejemplo de la ingeniería del mañana, con un consumo de electricidad un 77% inferior que hoteles comparables que operan con tecnología energética convencional. Mediante el despliegue de la mejor tecnología medioambiental y energética, el hotel se aproxima a la neutralidad en carbono. THE LUXURY HOTEL OF TOMORROW THAT’S DRIVEN BY DRIVES Designed for sustainability, Crowne Plaza Copenhagen Towers is a true example of tomorrow’s engineering, with 77% lower electricity consumption than comparable hotels operating conventional energy technology. By deploying the best environmental and energy technology, the hotel comes close to achieving carbon neutrality.
