Analysis of Demand and Energy Saving at Different Types of Hotels with Integration of Solar Systems and Geothermal Heat Pumps
Abstract
Performance analyses for integration of solar thermal, PV and geothermal heat pumps to different hotel typologies have been carried out in order to evaluate the potential of self-consumption promoted by European Directives. Hotels are located in different climatic zones of Spain and Italy. Using the software TRNBuild®, the buildings have been created and run under TRNSYS Simulation Studio. Four typologies of hotels (urban, rural, beach and mountain) and five categories of guests were created (family, couple, youth, organized travel group and business), reflecting existing different patterns of energy consumption. Three Spanish provinces and one mountain site in Italy with different weather conditions have been selected to calculate total thermal, electrical and domestic hot water (DHW) demand. Systems were sized to cover approximately 70% of DHW demand, according to Spanish Normative. In addition, by using the selected technologies it is possible to supply all the electricity demand according to different patterns. In particular, it will be shown that it is possible to supply 50% of total energy with PV panels - a value above the objectives of the European Union for 2020.
