Possibilities for High Temperature Cooling in Tourism Accommodation Facilities

Considering that energy consumption in hotels, depending on energy system efficiency is between 250 – 550 kWh/m2 per year, tourism accommodation sector is undoubtedly responsible for a large ratio of CO2 emissions. Although approximately half of that amount is utilized by HVAC systems that provide thermal comfort for guests, utilization of energy efficiency technologies and renewable energy sources is not even approaching the satisfactory level. This paper analyses different renewable energy sources for high temperature cooling in Mediterranean region. Taking into account climate and geographical conditions it is possible to design centralized coo ling system that would provide cold water temperature of 17oC to the radiant cooling system in the guest rooms. Significant energy and environmental savings can be achieved using both seawater cooling system where seawater can be consider as unlimited renewable source and solar absorption refrigeration system. Therefore, sustainable approach in building and energy system in tourism accommodation facilities is necessary in order to achieve sustainable development of tourism that is one of the world’s most rapidly growing industry
