30|REPORTAJE Oscar Alonso, head of the Department of Energy Efficiency and Sustainability of Hotel Technology Institute (ITH), explained to iCandela that the Efficient Hotels Route aimed to raise knowledge of best practice in environmental policy, energy efficiency and sustainability in five establishments in Madrid. For Alonso, “these five hotels show that it is possible to improve energy efficiency and sustainability taking action in many different areas, linked to the management of the property and the activities related to the hotel business. ITH have chosen these five hotels not only because they exemplify environmental policies or ener- gy management in many different ways, but also because they have opted for efficiency and balance with the environment in anticipation of future tighter European regulations and market demand itself increasingly more sensitized to the environmental impact of tourism activities“. HoTEL DE LAS LETRAS The Hotel de las Letras, part of the chain Anima Ho- tels, has a policy of sustainability and energy efficien- cy from the design conceived during the project of rehabilitation of this historic building, which included the addition of a system control platform of energy consumption. In low energy consumption lighting with LED technology, presence detectors in hallways and common areas, timers, twilight cells and VRV type air conditioning systems are some of the basic measures that complement the management by iGreen, moni- toring and management system energy demand, that through network analyzers, sensors and pulse readers collects, by the second, the information of what the hotel is consuming. ■
