A Statistical Approach to the Prediction of the Energy Performance of Hotel Stock

The issue of evaluating possible strategies for improving the building stock's energy and environmental performance is crucial. This applies to all buildings including residential and non-residential. In particular, hotels represent a group of both economic importance and public interest. Within the frame of a field study, and in a bottom-up approach, data related to the energy and environmental performance of Hellenic hotels were gathered, along with information related to occupancy levels, indoor environmental quality matters and management procedures. At the same time, and in a top-down approach, data were obtained from the Hellenic Tourism Organization and the national and regional Hotel Chambers. These data provide a reliable background in order to elaborate statistical indices, such as the mean, mode and median for the energy performance of various hotel groups. The idea of a "typical" hotel, as well as its respective performance, remains, however, vague and has to be linked to the aforementioned bottom-up approach. The present analysis is an attempt to group the main features via descriptive statistics and identify possible associations and correlations between energy figure factors.
