The tests were performed in a climatic chamber at the <jats:italic>Pietro Pisa Laboratory<\/jats:italic> of the University of Brescia. The wall thermal performance has been evaluated by examining four scenarios in which the cavities have been filled with insulating material made of cellulose-based recycled flakes characterized by a declared thermal conductivity of 0.038 W\/mK. The wall thermal transmittance <jats:italic>U<\/jats:italic> is measured based on the temperatures and heat fluxes measured through the structure. Based on the degree of filling, the wall thermal transmittance ranges between 1.58 W\/m<jats:sup>2<\/jats:sup>K for the wall without insulation, and 0.28 W\/m<jats:sup>2<\/jats:sup>K for the configuration with all cavities completely filled.<\/jats:p>","DOI":"10.1088\/1742-6596\/2685\/1\/012034","type":"journal-article","created":{"date-parts":[[2024,2,1]],"date-time":"2024-02-01T14:03:16Z","timestamp":1706796196000},"page":"012034","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Improving the energy performance of a 3D-printed wall using recycled material"],"prefix":"10.1088","volume":"2685","author":[{"given":"M","family":"Neri","sequence":"first","affiliation":[]},{"given":"L","family":"Licciardello","sequence":"additional","affiliation":[]},{"given":"A","family":"Reggia","sequence":"additional","affiliation":[]},{"given":"M","family":"Pilotelli","sequence":"additional","affiliation":[]},{"given":"A M","family":"Lezzi","sequence":"additional","affiliation":[]}],"member":"266","reference":[{"key":"JPCS_2685_1_012034bib1","doi-asserted-by":"crossref","first-page":"281","DOI":"10.1016\/j.jclepro.2017.08.165","article-title":"Additive manufacturing of geopolymer for sustainable built environment","volume":"167","author":"Panda","year":"2017","journal-title":"Journal of Cleaner Production"},{"key":"JPCS_2685_1_012034bib2","doi-asserted-by":"crossref","DOI":"10.1016\/j.autcon.2023.104751","article-title":"Robotic 3D printing of concrete building components for residential buildings in Saudi Arabia","volume":"148","author":"Alabbasi","year":"2023","journal-title":"Automation in Construction"},{"key":"JPCS_2685_1_012034bib3","article-title":"A process classification framework for defining and describing digital fabrication with concrete","volume":"134","author":"Buswell","year":"2020","journal-title":"Cement and Concrete Resources"},{"key":"JPCS_2685_1_012034bib4","doi-asserted-by":"crossref","first-page":"e00586","DOI":"10.1016\/j.cscm.2021.e00586","article-title":"Fire performance of innovative 3D printed concrete composite wall panels \u2013 A Numerical Study","volume":"15","author":"Suntharalingam","year":"2021","journal-title":"Case Studies in Construction Materials"},{"key":"JPCS_2685_1_012034bib5","doi-asserted-by":"crossref","first-page":"558","DOI":"10.1016\/j.cemconres.2011.12.003","article-title":"Hardened properties of high-performance printing concrete","volume":"42","author":"Le","year":"2012","journal-title":"Cement and Concrete Research"},{"key":"JPCS_2685_1_012034bib6","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1007\/s43452-020-00017-1","article-title":"Mechanical behaviors of 3D printed lightweight concrete structure with hollow section","volume":"20","author":"Wang","year":"2020","journal-title":"Archives of Civil and Mechanical Engineering"},{"key":"JPCS_2685_1_012034bib7","doi-asserted-by":"crossref","first-page":"432","DOI":"10.3390\/buildings11100432","article-title":"Energy Performance of 3D-Printed Concrete Walls: A Numerical Study","volume":"11","author":"Suntharalingam","year":"2021","journal-title":"Buildings"},{"key":"JPCS_2685_1_012034bib8","doi-asserted-by":"crossref","DOI":"10.1016\/j.jobe.2020.101286","article-title":"Energy efficient 3D printed buildings: Material and techniques selection worldwide study","volume":"30","author":"Alkhalidi","year":"2020","journal-title":"Journal of Building Engineering"},{"key":"JPCS_2685_1_012034bib9","doi-asserted-by":"crossref","first-page":"e01945","DOI":"10.1016\/j.cscm.2023.e01945","article-title":"Towards development of sustainable lightweight 3D printed wall building envelopes \u2013 Experimental and numerical studies","volume":"18","author":"Cuevas","year":"2023","journal-title":"Case Studies in Construction Materials"},{"author":"Italian Republic.
