: In the very near future, energy efficient hotels will cease to be the exception but will be the rule. Energy conservation and the intelligent utilization of renewable energy sources are prerequisite for sustainable development of tourism. Due to global warming and increased standards in hotel industry, there is an increasing demand for energy for cooling in general, although this is especially reflected in hotel industry peaking in summer period. Furthermore, energy demand for hot water and food and beverages preparation in a hotel increases proportionally with the number of tourists. All these energy issues are overburdening the ever competing hotel industry. Hotels, in order to optimize their energy costs and implementation of renewable energy sources utilization, have to perform energy audit - an analysis of thermal performance and energy systems of building with the purpose to determent its energy efficiency or non-efficiency. This paper combines energy audit methodology with properties of energy consumption in hotel industry with an aim to provide guidelines for modern hotel energy management.
