Field testing the heat transfer coefficient of the outer walls of an energy conservation demonstration project in Changchun by temperature controlled tank - heat flow meter method. The accuracy of the field detector in build-ing envelope and the influence factors on the heat transfer coefficient of building envelope are analyzed, such as so-lar radiation, the convection and radiation in the hot box, weather conditions and so on. The experimental results show that the application of temperature controlled tank - heat flow meter method in field testing the building enve-lope has the characteristics of convenient operation and accurate data. Field test should try to avoid solar radiation, radiation temperature in the hot box and other factors to affect the test result.
