Abstract
Due to the measuring distance, there are variable degrees of temperature measurement differences when infrared temperature monitoring technology is employed to take the temperature of a building envelope, which can directly lead to distortion in the detection of the building envelope temperature. In order to address this issue, temperature data from 20 sets of different measurement locations were acquired through field testing analyzing the building envelope and the interior latex-painted wall. By fitting polynomials to the temperature error and distance curves, a model of the temperature-distance compensation function was produced. According to the results, it is possible to precisely estimate the temperature of latex-painted interior walls at a distance of 0.25 meters using an instrument. The temperature-distance compensation model is executed as the measurement distance increases, resulting in a maximum error rate of 1% for temperature readings after compensation. Before adjustment, the error rate in measuring temperature was 4.9%; after adjustment, it is 3.9%.
