This study combines on-site measurements, simulations, and a life cycle assessment to assess some relevant parameters concerning the acoustic, thermal and environmental performance of the 3D-printed house. The main objectives are to analyze whether the house complies with the acoustic and thermal regulations and to assess whether it can act as a sustainable alternative to conventional masonry construction, especially when time plays an important role. The build surface (3D prototype) of the house is approximately 23 m2. The internal space includes a living room (12.35 m2), a bedroom (7.36 m2) and a bathroom (3.16 m2). The total surface of the house is 22.87 m2 and it has a volume of 64.03 m3. The acoustic insulation was measured according to the ISO 9869-1:2014 standard. In terms of the acoustic insulation, the sound reduction index was tested following the guidelines of the ISO 140-5:1999 standard. Additionally, the study includes a comparative life cycle assessment comparing the 3D-printed fa\u00e7ade with two conventional wall typologies. The 3D-printed house displays an excellent thermal performance, with a measured thermal transmittance of 0.24 Wm\u22122K\u22121, suitable for all Spanish climate zones. Regarding the acoustic insulation, the measured global sound reduction indexes of the fa\u00e7ades range from 36 to 45 dB, which is adequate for areas with noise levels of up to 75 dB. The environmental results indicate that 3D-printed fa\u00e7ade manufacturing emits 30% more CO2e than a fa\u00e7ade constructed using concrete blocks and 2% less than a masonry block wall. Overall, this study shows that, in addition to its multiple advantages in terms of the construction time, the studied 3D-printed house has similar acoustic, thermal and environmental traits to the most common construction typologies. However, it cannot be considered a sustainable construction method due to its high amount of cement.<\/jats:p>","DOI":"10.3390\/su142013204","type":"journal-article","created":{"date-parts":[[2022,10,17]],"date-time":"2022-10-17T05:08:02Z","timestamp":1665983282000},"page":"13204","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["The First 3D-Printed Building in Spain: A Study on Its Acoustic, Thermal and Environmental Performance"],"prefix":"10.3390","volume":"14","author":[{"given":"Andrea","family":"Salandin","sequence":"first","affiliation":[{"name":"Center for Physics Technologies (CTFAMA), Universitat Polit\u00e8cnica de Val\u00e8ncia, 46022 Val\u00e8ncia, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8911-595X","authenticated-orcid":false,"given":"Alberto","family":"Quintana-Gallardo","sequence":"additional","affiliation":[{"name":"Center for Physics Technologies (CTFAMA), Universitat Polit\u00e8cnica de Val\u00e8ncia, 46022 Val\u00e8ncia, Spain"}]},{"given":"Vicente","family":"G\u00f3mez-Lozano","sequence":"additional","affiliation":[{"name":"Center for Physics Technologies (CTFAMA), Universitat Polit\u00e8cnica de Val\u00e8ncia, 46022 Val\u00e8ncia, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5546-1486","authenticated-orcid":false,"given":"Ignacio","family":"Guill\u00e9n-Guillam\u00f3n","sequence":"additional","affiliation":[{"name":"Center for Physics Technologies (CTFAMA), Universitat Polit\u00e8cnica de Val\u00e8ncia, 46022 Val\u00e8ncia, Spain"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"102","DOI":"10.1016\/j.matdes.2016.03.097","article-title":"Large-scale 3D printing of ultra-high performance concrete\u2013a new processing route for architects and builders","volume":"100","author":"Gosselin","year":"2016","journal-title":"Mater.
