This article is part of a broader research project aimed at employing artificial intelligence and big data techniques to develop a predictive system for the thermal behavior of the ground in very low-enthalpy geothermal applications. In this initial article, a summarized process is outlined to generate large quantities of synthetic data through a ground simulation method. The proposed theoretical model allows simulation of the soil\u2019s thermal behavior using an electrical equivalent. The electrical circuit derived is loaded into a simulation program along with an input function representing the system\u2019s thermal load pattern. The simulator responds with another function that calculates the values of the ground over time. Some examples of value conversion and the utility of the input function system to encode thermal loads during simulation are demonstrated. It bears the limitation of invalidity in the presence of underground water currents. Model validation is pending, and once defined, a corresponding testing plan will be proposed for its validation.<\/jats:p>","DOI":"10.3390\/data8120176","type":"journal-article","created":{"date-parts":[[2023,11,23]],"date-time":"2023-11-23T11:31:25Z","timestamp":1700739085000},"page":"176","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Model Design and Applied Methodology in Geothermal Simulations in Very Low Enthalpy for Big Data Applications"],"prefix":"10.3390","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-4767-3179","authenticated-orcid":false,"given":"Roberto","family":"Arranz-Revenga","sequence":"first","affiliation":[{"name":"Departamento de Ingenier\u00eda Geol\u00f3gica y Minera, Escuela T\u00e9cnica Superior de Ingenieros de Minas y Energ\u00eda, Universidad Polit\u00e9cnica de Madrid, 28003 Madrid, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-9629-7300","authenticated-orcid":false,"given":"Mar\u00eda Pilar","family":"Dorrego de Lux\u00e1n","sequence":"additional","affiliation":[{"name":"Canal de Isabel II, \u00c1rea de Infraestructura Inform\u00e1tica, 28003 Madrid, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7656-1707","authenticated-orcid":false,"given":"Juan","family":"Herrera Herbert","sequence":"additional","affiliation":[{"name":"Departamento de Ingenier\u00eda Geol\u00f3gica y Minera, Escuela T\u00e9cnica Superior de Ingenieros de Minas y Energ\u00eda, Universidad Polit\u00e9cnica de Madrid, 28003 Madrid, Spain"}]},{"given":"Luis Enrique","family":"Garc\u00eda Cambronero","sequence":"additional","affiliation":[{"name":"Departamento de Ingenier\u00eda Geol\u00f3gica y Minera, Escuela T\u00e9cnica Superior de Ingenieros de Minas y Energ\u00eda, Universidad Polit\u00e9cnica de Madrid, 28003 Madrid, Spain"}]}],"member":"1968","published-online":{"date-parts":[[2023,11,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Grassi, W.
