40|REPORTAJE MERCuRE SANTo DoMINgo Finally, the Mercure Santo Domingo Hotel has also desig- ned a comprehensive environmental management, eco- sustainable, which provides two views: conventional mea- sures primarily aimed at getting the best ratio of energy cost / product and service rended, and the marketing approach and product innovation, focused on delivering products and services in a sustainable culture frame and balanced with the environment. In terms of equipment, the hotel has installed energy correction reactive conditio- ners with inverter technology, solar collectors to produce ACS, efficient elevators that save up to 20% of energy; double sealing in all rooms, control tools and monitoring of electricity consumption, and induction cookers, reco- very systems of waste waters for irrigation, among other measures. To amplify the quantitative results, this hotel has also implemented other measures to reconcile sustainability and ecological culture as differentiators and advantages that make this building and its facilities a unique and spe- cial place, among which we can specially mention its fa- mous vertical garden the World’s Biggest Hanging Garden according to the Guinness Book of Records, with plants and flowers that change with each season and which can be seen from all perspectives, thanks to its completely unusual combinations and heights. This vertical garden obtains other benefits beyond the purely ornamental, such as improving thermal insulation, reducing CO2 emissions and creating a microclimate that can cut between 3 and 5 degrees the temperature of the area in which the hotel is located. Its closed circuit water- fall and fed by treated waste water, nearly 20 meters high and twenty-six different types of jets, helps to improve and correct the environmental humidity in Madrid typical dryness. The idea of moving nature to the hotel is also re- flected in the rooms. Bathrooms offer striking decorations that combine aesthetics and low maintenance materials, which can be renewed quickly, thanks to its detachable design that allows replacing parts in 15 minutes, and in- clude decorative elements inspired by the sea, or autumn landscapes or its spectacular and iconic garden. ■
