diverse external temperatures and the divergent comfort temperature between native dwellers and visiting tourists). Considering the fact that a building’s operational costs will grow with time and that problems only get worse unless some actions are taken, there is a clear need for proper building maintenance, refurbishment or retrofitting (upgrading). Such actions should focus on the building’s structural elements and installations, which can also improve energy performance and indoor environmental quality. The hotel sector is uniquely placed to provide the impetus for change in business behavior within tourism, because of its multiplier effect on guests, staff and suppliers, as well as the central role that hotels play within local communities. Additionally, possible energy conservation techniques for RUE and exploitation of RES have a unique demonstration potential and a high exposure to millions of people that visit hotels at one time or another. Hotels are usually located in areas with high seasonal energy loads, and frequently with high energy cost and low supply (i.e. islands). Figure 1.
