Abstract
The anti-condensation performance evaluation is conducted in accordance with Design Standard for Preventing Condensation in Apartment Buildings since December 2013. The purpose of this study is to assess the suitability of anti-condensation evaluation performance method at the wall junction. In the case of wall junction, the anti-condensation performance evaluation is carried out by determining one of two methods: designing according to the guidelines or calculating TDR(Temperature Difference Ratio) by simulation programs. It is much simpler and cheaper to design according to the guidelines than to calculate TDR, so most of evaluation are performed using guideline. However, the points suggested in the guidelines are limited to the bedroom. In the case of the bathroom, the composition of the floor insulation is different from that of the bedroom due to waterproofing and piping equipment. This detailed section is missing from the guidelines. This study compared the evaluation results performed in two different methods for the evaluation points that are able to lead to condensation. Several evaluation points were designed to meet the guidelines, but exceeded TDR. This means that the guidelines can not cover all of evaluation points. Therefore it is necessary to revise and supplement the guidelines.
