Determination and behavior of energy baseline and performance indicators in hotel facilities in Varadero, Cuba. Universidad y Sociedad [online]. 2023, vol.15, n.5, pp. 85-92.  Epub Oct 10, 2023.

This work was carried out in a group of 10 hotels located in the Varadero resort. Considering that the energy carrier that is most consumed in these hotels is electricity (more than 90%), indicators related to the consumption of this carrier were evaluated. For this, data on general electricity consumption and occupied rooms-day (HDO) per month in these hotels were used, for two consecutive years. The daily mean dry bulb temperature data, taken from the Varadero meteorological station of those years, were also used. From the previous data, the base temperature, cooling degree days (DGE) and the base line of electricity consumption in said hotels were determined based on the combined variable (HDG). Then two energy performance indicators were determined, namely: General electricity consumption index (kWh / RDD) and Energy not associated with the service (%), two ways of reporting energy performance were also determined: Variance graph of target energy/actual energy (%) and trend (CUSUM) of energy variance (kWh), verifying that they are feasible to use and demonstrating the existing overconsumption in some hotels.

Keywords : Hotels; Energy performance indicators; Base temperature; Cooling degree days.
