Calculation of energy performance indicators of a company in the hotel sector

Abstract

This paper presents the calculation of energy performance indicators of a company in the hotel sector in Barranquilla, Colombia. For the calculation of the saving potentials, two-year electricity and gas consumption data (2014-2015) were analyzed, an inventory was made of all the energy consuming equipment and the power quality was measured in those with greater significant use of energy. The methodology used for this study is based on the tools of an Energy Management System (EMS). When analyzing the information, it was found that 71% of the primary energy is electrical and that there is a correlation between the monthly consumption of electric power and the equivalent occupation corresponding to 67%, which indicated that the variations in energy consumption were determined and affected significantly by the change in monthly equivalent occupation (OE). On the other hand, it was found that the mathematical model of this behavior is represented by a Baseline calculated from which it was found that the energy not associated to the equivalent occupation (OE) represents 59% of the average monthly electrical energy consumed. As for the target line which reflects the existence of best operational practices for the same occupation level.

Selection of the Energy Performance Indicator for Hotels Based on ISO 50001: A Case Study

“…These results can be seen in Figure 10, which coincide with those obtained by [9]. As shown in Figure 10, the correlation value (R 2 ) of the energy goal line is approximately 0.97; it is possible to incorporate this goal line as the future energy baseline of the Hotel.…”

“…However, most researchers agree that the variable Days Degrees (DG) has a marked influence on the energy consumption of the installation if the air conditioning is the most consumed service in the Hotel. It is then necessary to incorporate the DG as an influencing variable in energy consumption [7,9,28,[41][42][43].…”

“…Around this, the need arises to permanently maintain and guarantee the best conditions of cleaning, lighting, air conditioning, and ventilation, which requires an investment of thermal and electrical energy through different sources such as natural gas, electricity, and diesel. In hotel organizations, energy expenditure ranges from 3% to 6% of total expenses, so their savings and management represent a significant contribution to the finances company [7,9].…”
