ENERGY-CONSERVATION AND RETROFITTING POTENTIAL IN HELLENIC HOTELS

Energy consumption data from 158 Hellenic hotels and estimated energy savings that result from the use of practical retrofitting techniques, materials and new energy efficient systems are presented. The data we re collected during an extensive energy audit of buildings that was ca rried out in Hellas, within the frame of a National Energy Programme s ponsored by the CECVALORENProgramme, for energy conservation in buildi ngs. During this short monitoring campaign and on-site visits of a tra ined panel of engineers to each building, all information related to t he building's construction, heating, cooling and lighting systems, and all other mechanical and electrical systems, was collected. The main results and energy characteristics of cooling, heating and lighting on energy consumption and performance are discussed. The annual average total energy consumption in hotels is 273 kWh/m(2), one of the highest among all categories of buildings. Several scenarios for possible int erventions to the building's outer envelope, heating, cooling and ligh ting systems are proposed and evaluated, in order to assess the effect iveness of various energy conservation techniques. Based on the result s from several simulations, it is concluded that it is possible to rea ch an overall 20% energy conservation.
