Five of the patient rooms had active EC windows that tint dynamically to control for heat and glare, and the other five rooms had deactivated EC windows that simulated traditional windows and blinds. Samples were collected one day before patient admission as baseline and on the 1st, 3rd, and 5th day of the patient stay. Total bacterial abundance and bacterial community structure were determined through quantitative PCR and 16s rRNA Illumina MiSeq sequencing, respectively.<\/jats:p>\n\t  <\/jats:sec>\n\t  <jats:sec id=\"S2732494X24003449_as4\">\n\t    <jats:title>Results:<\/jats:title>\n\t    <jats:p>Patient rooms with active EC windows had significantly lower light intensity and temperature than traditional patient rooms with blinds. The absolute bacterial abundance and diversities on windows were significantly lower in rooms with EC windows and the bacterial composition changed after one day EC window activation. Compared to baseline, relative abundance of the <jats:italic>Staphylococcus<\/jats:italic> genus was significantly lower on EC window surface during the five-day experiment. In contrast, the air microbiome was more diverse in rooms with EC windows.<\/jats:p>\n\t  <\/jats:sec>\n\t  <jats:sec id=\"S2732494X24003449_as5\">\n\t    <jats:title>Conclusion:<\/jats:title>\n\t    <jats:p>Active electrochromic (EC) windows in patient rooms result in lower light intensity and temperature, reduced bacterial abundance and diversities on window surfaces, and a more diverse air microbiome, informing future healthcare design.<\/jats:p>\n\t  <\/jats:sec>","DOI":"10.1017\/ash.2024.344","type":"journal-article","created":{"date-parts":[[2024,10,25]],"date-time":"2024-10-25T11:05:07Z","timestamp":1729854307000},"source":"Crossref","is-referenced-by-count":1,"title":["The spatial and temporal effect of electrochromic windows on indoor and human microbiome in an inpatient hospital"],"prefix":"10.1017","volume":"4","author":[{"given":"Man In","family":"Lam","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8316-7476","authenticated-orcid":false,"given":"Kelsey","family":"Gleason","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7513-532X","authenticated-orcid":false,"given":"Allen B.","family":"Repp","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-2994-7166","authenticated-orcid":false,"given":"Sam","family":"Yeo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kinga","family":"Vojnits","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3875-2481","authenticated-orcid":false,"given":"Piers","family":"MacNaughton","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3615-1858","authenticated-orcid":false,"given":"Sepideh","family":"Pakpour","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2024,10,25]]},"reference":[{"key":"S2732494X24003449_ref28","doi-asserted-by":"publisher","DOI":"10.3390\/microorganisms10020225"},{"key":"S2732494X24003449_ref19","doi-asserted-by":"publisher","DOI":"10.1186\/s40168-015-0108-3"},{"key":"S2732494X24003449_ref23","doi-asserted-by":"publisher","DOI":"10.3389\/fmicb.2017.02336"},{"key":"S2732494X24003449_ref1","doi-asserted-by":"publisher","DOI":"10.15666\/aeer\/1704_82358259"},{"key":"S2732494X24003449_ref21","doi-asserted-by":"publisher","DOI":"10.1038\/s41579-018-0065-5"},{"key":"S2732494X24003449_ref5","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhin.2011.05.002"},{"key":"S2732494X24003449_ref30","doi-asserted-by":"publisher","DOI":"10.1097\/JMQ.0000000000000119"},{"key":"S2732494X24003449_ref13","doi-asserted-by":"publisher","DOI":"10.3389\/frsc.2021.690055"},{"key":"S2732494X24003449_ref26","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajic.2011.12.017"},{"key":"S2732494X24003449_ref29","doi-asserted-by":"publisher","DOI":"10.3390\/ijerph17093219"},{"key":"S2732494X24003449_ref22","doi-asserted-by":"publisher","DOI":"10.3390\/d13100475"},{"key":"S2732494X24003449_ref16","volume-title":"Microbiomes of the Built Environment","year":"2017"},{"key":"S2732494X24003449_ref31","doi-asserted-by":"publisher","DOI":"10.1007\/s40572-015-0063-y"},{"key":"S2732494X24003449_ref14","doi-asserted-by":"publisher","DOI":"10.1016\/j.scitotenv.2017.05.105"},{"key":"S2732494X24003449_ref11","doi-asserted-by":"publisher","DOI":"10.1111\/jasp.12764"},{"key":"S2732494X24003449_ref12","doi-asserted-by":"publisher","DOI":"10.3390\/ijerph18199980"},{"key":"S2732494X24003449_ref2","first-page":"Doc06","article-title":"Cleaning and disinfection of surfaces in hospitals.
