The outside convective heat transfer coefficient (CHTC) of building roof is an important parameter foraccurately calculating heat transfer through roof and simulating airflow around buildings. However, thecorrelations concerning CHTC in various studies seem to be discrepant. The experiment usingnaphthalene method to measuring CHTC was carried out on a nine-story building roof during 15 August2006-22 August 2006. Test specimens with glazed surface were ranged at twenty points on buildingroof. Test specimens used in this study were cast by molten naphthalene in molds.
