The impact of solar radiation and thermal inertia of the materials that make up the multi-layer enclosures substantially modify thermal transmittance behaviour of the enclosures. This dynamic form of heat transfer, additionally affected by indoor HVAC systems, has a substantial effect on the parameters that define comfort. It also has an impact on energy demand within a daily cycle as well as throughout a one-year use cycle. This study describes the destructive monitoring of an existing block of flats located in Alicante. Once the enclosure was opened, sensors of temperature (PT100), air velocity, and relative humidity were located in the different layers of the enclosure, as well as in the interior and exterior surfaces. A pyranometer was also installed to measure solar radiation levels. A temperature data correction algorithm was drawn up to address irregularities produced in the enclosure. The algorithm was applied using a Raspberry Pi processor in the data collection system. The comparative results of temperature gradients versus non-destructive monitoring systems are presented, providing measures of the transmittance value, surface temperatures and indoor and outdoor air temperatures. This remote sensing system can be used in future studies to quantify and compare the energy savings of different enclosure construction solutions.<\/jats:p>","DOI":"10.3390\/s17122848","type":"journal-article","created":{"date-parts":[[2017,12,8]],"date-time":"2017-12-08T11:37:40Z","timestamp":1512733060000},"page":"2848","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":32,"title":["Thermal Transmission through Existing Building Enclosures: Destructive Monitoring in Intermediate Layers versus Non-Destructive Monitoring with Sensors on Surfaces"],"prefix":"10.3390","volume":"17","author":[{"given":"V\u00edctor","family":"Echarri","sequence":"first","affiliation":[{"name":"Department of Architectural Constructions, University of Alicante, Carretera San Vicente del Raspeig, s\/n, 03690 San Vicente del Raspeig, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Almudena","family":"Espinosa","sequence":"additional","affiliation":[{"name":"Department of Achitecture, University of Zaragoza, Calle Mar\u00eda de Luna, 3, 50018 Zaragoza, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carlos","family":"Rizo","sequence":"additional","affiliation":[{"name":"Department of Architectural Constructions, University of Alicante, Carretera San Vicente del Raspeig, s\/n, 03690 San Vicente del Raspeig, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2017,12,8]]},"reference":[{"key":"ref_1","unstructured":"(2017, November 10).
