Reliability Field Test of the Air–Surface Temperature Ratio Method for In Situ Measurement of U-Values
This study proposes the air–surface temperature ratio (ASTR) method as an in situ measurement method to rapidly and accurately measure wall U-values in existing houses. Herein, the wall U-values were measured in situ applying the heat flow meter (HFM) method of ISO 9869-1 and the ASTR method. The re...
