XENIOS - a methodology for assessing refurbishment scenarios and the potential of application of RES and RUE in hotels

Hotels rank in the highest levels of energy consumption in the tertiary building sector. Improved service quality mandates that hotel building, facilities and installations are maintained to the highest standards in order to remain competitive, thus renovations are becoming common. Renovation is usually financially attractive when compared to demolition and reconstruction. This offers great opportunities for promoting energy efficient measures, exploitation of renewable energy sources (RES) and rational use of energy (RUE) in the hotel sector. The XENIOS methodology and software permits the user to perform a preliminary hotel audit and make a first assessment of cost-effective energy efficient renovation practices, technologies and systems. This paper presents a brief overview of the methodology and the various features of the XENIOS software and focuses on the results from four audits and a pilot study carried out in Mediterranean hotels.
