The work deals with the study of the Energy Planning stage according to the ISO 50001:2018 Standard at the Hotel Punta la Cueva in Cienfuegos, Cuba. The current energy management indicators for hotels are well-studied. However, the study aims to incorporate the variable Degree-Days in the Room Days Occupied (RDO) to establish a correct Baseline and Energy Performance Indicator. The methodology followed is based on the energy management standards of energy review stage. The fundamental results were in obtaining the Energy Baseline with a Coefficient of Determination (R2) of 0.97. One of the opportunities for improvement consisted of the replacement of 80 bulbs 15 W with 9 W LED bulbs. It has an Internal Rate of Return (IRR) of 28%, a Present Value Net Income (NPV) of 71.5 USD, and an Investment Recovery Period (PRI) of 3.6 years. The second opportunity is a preliminary project for a Photovoltaic Solar System on the roofs of the buildings, where it is possible to install 1011 photovoltaic and achieve a generation of 384 kilowatt-peak (kWp).
En el presente estudio se aplicaron algunas de las herramientas de la economía ecológica para evaluar la sostenibilidad de las principales biomasas en la provincia de Cienfuegos, Cuba. Para ello se seleccionaron como principales biomasas el bagazo de caña; cachaza, como residuo del proceso de clarificación del jugo de caña; los llamados “Residuos Agrícolas de Cosecha” (RAC), cascarilla de arroz y residuos forestales. Se determinaron las cantidades disponibles a través del levantamiento en cada unidad productora para, con ello, estimar la energía total y la reducción de CO2 arrojada a la atmósfera para cada fuente de biomasas. Finalmente, se aplicó el método de jerarquía analítica (AHP en inglés) como técnica de decisión de multicriterios para evaluar la sostenibilidad de las alternativas de biomasas presentadas. Además, se realizó un análisis de sensibilidad debido a la subjetividad que presenta esta técnica de decisión.
