In many situations, the application of conventional system identification or approximate grey-box models, partly theoretic and partly data driven, is either unfeasible or unsuitable. The paper discusses and illustrates an application of black-box modelling achieved using data mining techniques with the purpose of smart building ventilation subsystem control. We present the implementation and evaluation of a data mining methodology on collected data from over one year of operation. The case study is carried out on four air handling units of a modern campus building for preliminary decision support for facility managers. The data processing and learning framework is based on two steps: raw data streams are compressed using the Symbolic Aggregate Approximation method, followed by the resulting segments being input into a Support Vector Machine algorithm. The results are useful for deriving the behaviour of each equipment in various modi of operation and can be built upon for fault detection or energy efficiency applications. Challenges related to online operation within a commercial Building Management System are also discussed as the approach shows promise for deployment.<\/jats:p>","DOI":"10.1155\/2019\/3572019","type":"journal-article","created":{"date-parts":[[2019,3,12]],"date-time":"2019-03-12T23:30:44Z","timestamp":1552433444000},"page":"1-14","source":"Crossref","is-referenced-by-count":14,"title":["Data-Driven Modelling of Smart Building Ventilation Subsystem"],"prefix":"10.1155","volume":"2019","author":[{"ORCID":"http:\/\/orcid.org\/0000-0002-9647-6817","authenticated-orcid":true,"given":"Grigore","family":"Stamatescu","sequence":"first","affiliation":[{"name":"Department of Automatic Control and Industrial Informatics, University \u201cPolitehnica\u201d of Bucharest, 313 Splaiul Independentei, 060042 Bucharest, Romania"}]},{"ORCID":"http:\/\/orcid.org\/0000-0002-4484-4534","authenticated-orcid":true,"given":"Iulia","family":"Stamatescu","sequence":"additional","affiliation":[{"name":"Department of Automatic Control and Industrial Informatics, University \u201cPolitehnica\u201d of Bucharest, 313 Splaiul Independentei, 060042 Bucharest, Romania"}]},{"given":"Nicoleta","family":"Arghira","sequence":"additional","affiliation":[{"name":"Department of Automatic Control and Industrial Informatics, University \u201cPolitehnica\u201d of Bucharest, 313 Splaiul Independentei, 060042 Bucharest, Romania"}]},{"ORCID":"http:\/\/orcid.org\/0000-0002-0041-6431","authenticated-orcid":true,"given":"Ioana","family":"Fagarasan","sequence":"additional","affiliation":[{"name":"Department of Automatic Control and Industrial Informatics, University \u201cPolitehnica\u201d of Bucharest, 313 Splaiul Independentei, 060042 Bucharest, Romania"}]}],"member":"98","reference":[{"issue":"4","key":"1","first-page":"226","volume":"16","year":"2017","journal-title":"International Journal of Computing"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1016\/j.rser.2016.11.132"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.3390\/en11040772"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1016\/j.scs.2015.12.001"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1016\/j.rser.2017.04.095"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1016\/j.rser.2018.04.013"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1155\/2018\/1757409"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1016\/j.egypro.2017.07.400"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.3390\/en10030321"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1016\/j.ins.2012.07.014"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1145\/3127023"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.3390\/en11030683"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1016\/j.enbuild.2016.07.026"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1016\/j.eswa.2016.03.002"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1016\/j.jobe.2018.01.008"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.1016\/j.procs.2016.04.213"},{"key":"20","doi-asserted-by":"publisher","DOI":"10.3390\/en10010118"},{"key":"23","doi-asserted-by":"publisher","DOI":"10.1145\/2379776.2379788"},{"key":"26","doi-asserted-by":"publisher","DOI":"10.1145\/568518.568520"},{"key":"27","doi-asserted-by":"publisher","DOI":"10.1007\/978-0-387-84858-7"},{"key":"28","first-page":"255","volume-title":"Pairwise classification and support vector machines","year":"1999"},{"key":"29","doi-asserted-by":"publisher","DOI":"10.1109\/MELE.2016.2614178"}],"container-title":["Journal of Sensors"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2019\/3572019.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2019\/3572019.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2019\/3572019.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,3,12]],"date-time":"2019-03-12T23:30:47Z","timestamp":1552433447000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/js\/2019\/3572019\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,3,12]]},"references-count":22,"alternative-id":["3572019","3572019"],"URL":"https:\/\/doi.org\/10.1155\/2019\/3572019","relation":{},"ISSN":["1687-725X","1687-7268"],"issn-type":[{"value":"1687-725X","type":"print"},{"value":"1687-7268","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,3,12]]}}}
