Intelligent Energy Consumption in the Balearic Islands Hotels Andreu Moià-Pola,1 , Pere RULLANa and Bartomeu ALORDA b a Department of Physics – Energy Engineering Research Group (GREEN) b Department of Physics – Electronic Systems Group (GSE) Abstract. Hotels, in which belong to the tertiary building sector, rank among the highest in the energy consumption sectors. The Balearic Islands are a representative example of tourist islands, with more than 2.500 Hotel and touristic industries, which implies with its approximately a half million available beds, an increase in 50% of the population at high season. High energy consumption in hours with low Renewable energy production are additional problems in this case. From the information of 250 Hotels were studied in order to investigate the levels of energy consumption and sustainability among them with future zero emissions scenarios. This paper analyses available information concerning energy consumption in hotels, with a focus on Electric demand ( most of them from HVAC systems). The aim is to determine a model for predict the energy consumption, and coupling it as much as possible, to the RES of energy demand. For arrive to this goal smart buildings can foster energy efficiency and tackle the reduction of CO2 emissions within the atmosphere. The Hotels can guarantee good lighting, ventilation, cooling rates, along with other aspects of building demands in real-time. Monitoring and sensing combined solutions with simple and efficient methods are the protagonists of advanced sustainable building technology, for instance, the implementation of smart strategies such as thermal storage or pumping systems..

Introduction Climate change is a fact, and the actual situation is a world emergency and the buildings have to reduce the CO2 emissions. Balearic Government have approved a plan to decarbonize the islands in 2050 with 100% of renewable energy for the electric production. Nowadays, energy efficiency in buildings is a prime objective for energy policy at regional, national and international levels, especially in Europe where many new policies have been applied.in application. Energy consumption in hotels is amongst the highest in the non-residential building sector in absolute values (an average of 150 kWh/m2) [9]. The difference lies on the efficiency processes and the unitary consumption of the users (especially in thermal necessities when considering the 1 Department of Physics – Mechanical Engineering Area.
