| Abstract: | In order to provide true and effective testing data for checking and accepting energy-saving buildings, the quick-testing instrument of heat transfer coefficient of envelop is developed, which will test and evaluate performance of the buildings. According to testing data, the estimates of heat transfer coefficient of envelope are separately extracted from the testing datum by genetic algorithm and least square method. Comparing the consequence, the results show that genetic algorithm is available to this issue and has higher precision. |
