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 during high season. High energy consumption in hours with low Renewable energy production represent additional problems. Hotels consume the 15% of the total energy in the Balearic Islands. Data from 27 Hotels was studied in order to investigate the levels of energy

... ption and sustainability taking into consideration future zero emissions scenarios with solar energy production. This paper analyses available data concerning energy consumption in hotels, with a focus on Electric demand (most of them from HVAC systems). The main goal is to determine a mathematical model for predicting the energy consumption, and coupling it as much as possible to the solar energy production. To reach this goal, smart buildings can foster energy efficiency and tackle the reduction of CO2 emissions within the atmosphere. Hotels can guarantee adequate lighting, ventilation, cooling rates, along with other aspects of building demands in real-time. Monitoring and sensing combined solutions with simple and efficient control strategies are the main contributors to advanced sustainable building technology. The implementation of smart strategies such as thermal storage.
