The sound insulation performance of a MBT construction was assessed by tests done in situ. The results were compared with similar data from earlier measurements undertaken by the Building Physics Laboratory of the University of Minho in Portugal, and from simplified prediction methods. <\/jats:p><jats:p> The building where this comparison was done is a 3-storey building. The first 2 storeys were refurbished using conventional construction methods, but the 3rd storey was built using MBT methods, characterised by using lightweight materials, with high thermal insulation, and large fenestration areas. Based on the work undertaken, some conclusions and proposals for further work are presented. <\/jats:p>","DOI":"10.1260\/1351010041494737","type":"journal-article","created":{"date-parts":[[2004,7,28]],"date-time":"2004-07-28T00:15:58Z","timestamp":1090973758000},"page":"145-156","source":"Crossref","is-referenced-by-count":3,"title":["Case Study: Comparison between the Acoustic Performance of a Mixed Building Technology Building and a Conventional Building"],"prefix":"10.1177","volume":"11","author":[{"given":"Lu\u00eds","family":"Bragan\u00e7a","sequence":"first","affiliation":[{"name":"Department of Civil Engineering; University of Minho, Campus de Azur\u00e9m, 4800-058 Guimar\u00e3es, Portugal"}]},{"given":"Jorge","family":"Patr\u00edcio","sequence":"additional","affiliation":[{"name":"National Laboratory for Civil Engineering; Avenida do Brasil 101, 1700-066 Lisboa, Portugal"}]}],"member":"179","published-online":{"date-parts":[[2004,6,1]]},"reference":[{"key":"bibr1-1351010041494737","unstructured":"Bragan\u00e7a L.
