In this study, we compared standards for improving the performance of pipes based on their location to better the energy efficiency of buildings. We performed a simulated comparative analysis by measuring the temperature of each installed pipe and applying the insulation-thickness standard used at home and abroad. The pipe shaft located indoors maintained an almost constant temperature, but the pipe installed in an underground parking space was greatly affected by the outside temperature. In winter, the average temperatures of the inside pipe shaft and the one on the first-basement floor were 25.5¡É and 3.3¡É, respectively. The simulation analysis for each insulation-thickness criterion showed that the heat loss decreased by 1.7~2.2% when the overseas standard was applied. The analysis of the two installation locations showed that the average heat loss of the pipe installed in the underground parking space was 36.7% greater than that of the pipe that was installed indoors. |
