A response factor computer program has been used with actual climatic data to estimate indoor temperatures continuously over a period of six years in Melbourne, to determine such sequences of days for design purposes. The number of days of design data necessary varies with the type of building. Of the various climatic elements required for such an exercise at other locations, solar radiation at say hourly or three-hourly intervals is one parameter that may not be available. A comparison is made of the results obtained with estimated clear sky solar radiation and actual measured solar radiation, and the relationship between the two explored.</p></div>","PeriodicalId":9442,"journal":{"name":"Building Science","volume":"9 3","pages":"Pages 219-225"},"PeriodicalIF":0.0,"publicationDate":"1974-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0007-3628(74)90020-6","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91588724","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
