This project consists of a study on the design of an electrical installation and domestic hot water to meet the needs of a campsite near Tortosa, Spain. The main premise of the project is sustainability, so that all the necessary elements are implemented so that the campsite works independently, using renewable energies. The work proposal includes providing park users to enjoy a holiday in a peaceful and green environment, while reducing the ecological footprint. First, a study is carried out on the energy resources that are used in this type of enterprise, as well as on different facilities already in operation that are taken as a reference to the project. Then, the basis of the study is the dimensioning of energy resources using Excel software. Meteorological data was used which, together with the information provided by the manufacturers of commercial equipment, a whole solution capable of satisfying the energy consumption of the campsite is dimensioned. Finally, an assessment is made of the work carried out to determine the feasibility of the project in case it is decided to proceed with the construction of the campsite. Outgoing
