The WSN is able to track heat flows in various weather conditions in real-time. The developed system focuses on long-term in-situ building material variation analysis, which cannot be readily achieved using current approaches, especially when the number of measurement hotspots is large. This paper describes the implementation of the proposed system using the heat flow method enabled through an adaptable and low-cost wireless network, validated via a laboratory experiment.<\/jats:p>","DOI":"10.3390\/s20061755","type":"journal-article","created":{"date-parts":[[2020,3,24]],"date-time":"2020-03-24T07:16:08Z","timestamp":1585034168000},"page":"1755","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["A High-Resolution Open Source Platform for Building Envelope Thermal Performance Assessment Using a Wireless Sensor Network"],"prefix":"10.3390","volume":"20","author":[{"given":"Romwald","family":"Lihakanga","sequence":"first","affiliation":[{"name":"Institute for Infrastructure and Environment, Heriot Watt University, Edinburgh EH14 4AS, UK"},{"name":"Institute of Sensors, Signals and Systems, Heriot Watt University, Edinburgh EH14 4AS, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5953-3800","authenticated-orcid":false,"given":"Yuan","family":"Ding","sequence":"additional","affiliation":[{"name":"Institute of Sensors, Signals and Systems, Heriot Watt University, Edinburgh EH14 4AS, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6689-1702","authenticated-orcid":false,"given":"Gabriela M.","family":"Medero","sequence":"additional","affiliation":[{"name":"Institute for Infrastructure and Environment, Heriot Watt University, Edinburgh EH14 4AS, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Samuel","family":"Chapman","sequence":"additional","affiliation":[{"name":"Institute for Infrastructure and Environment, Heriot Watt University, Edinburgh EH14 4AS, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"George","family":"Goussetis","sequence":"additional","affiliation":[{"name":"Institute of Sensors, Signals and Systems, Heriot Watt University, Edinburgh EH14 4AS, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,3,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"51","DOI":"10.1016\/j.enbuild.2016.03.009","article-title":"A response factor-based method for the rapid in-situ determination of wall\u2019s thermal resistance in existing buildings","volume":"119","author":"Rasooli","year":"2016","journal-title":"Energy Build."},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Sujatmiko, W., Suhedi, F., and Rumiawati, A.
