Energy consultations were conducted in Indonesian resort hotels to get a deep insight into current energy practices and to develop improvement measures on a technical level. Soaring energy prices and a trend towards sustainable tourism in Indonesia make energy consumption an urgent question of business profitability in hotels. The research presents common consumption practices of small to large resorts and points out wasteful processes. As a guide for decision makers and engineers in the hotels a catalogue with improvement measures was developed, fitted to the Indonesian climate and energy market conditions. Energy efficient and renewable warm water supply solutions are assessed with dynamic economic methods and backed with sensitivity analyses, pointing out highly attractive investments and indicating a market for technology suppliers. Further innovative concepts for the exploitation of waste energy or renewable sources in resort hotels are discussed. The research reveals need for action and concludes with a set of key recommendations for decision makers in hotels.
