Energy Efficiency Indicators for Hotel Buildings

Abstract

Hotels are energy-intensive buildings; therefore, in this study, we investigate the indicators used for measuring the energy efficiency of one- to five-star hotels, in temperate and tropical regions of Asia, Europe, and Africa. There are several indicators for measuring energy intensity, but we found that the “total average annual energy use intensity index”, measured in kilowatt-hours per square meter per year (kWh/m2 year), was most often used. Surveys and energy audits are the methods used most often to collect the indicator data. Hotels in the tropics tend to consume more energy than those located in temperate zones, with four- and five-star hotels consuming the most energy.
