The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.1 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.3 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.0002 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.33 SJR: 0.256 SNIP: 0.49 CiteScore™:: 2.4 H-Index: 23

RESUMO

A potential sustainable option to improve thermal conditions in buildings is to use the Earth-air heat exchangers (EAHE), i. e., buried ducts where the air is blown to use the soil as a heat or cold sink. Despite being a simple and old technology, the interest for these devices has mainly increased in the last decades, accompanying global concerns with the use of renewable sources of energy and the advances in computer simulations. In countries like Brazil, the research about them is very limited, and their installations are just beginning. This paper aims to study the thermal performance of EAHE, under the variations of ducts diameter and the air velocity crossing them, adopting climatic and soil parameters found in experimental data from the south of Brazil. The thermal fields are computed using a validated complete model, and the results are used to find new sine-based models describing the thermal potential of EAHE, through which analytical analysis are made. From the study of the energy performance, significant improvement in thermal conditions can be obtained in the local summer at low energy consumption.
