에너지 저감을 위한 유지관리형 리모델링의 외벽 단열 성능기준 제안

Abstract

Purpose: We would like to propose an insulation-resistant design suitable for maintenance-type remodeling that conforms to green remodeling. Method: Permanent rental apartment houses in Seoul were selected for analysis. The current status of the target site was reviewed, and the representative households with similar shade environments and weak insulation were selected in consideration of Seoul’s climatic characteristics. As a research method, after climate analysis of Seoul TRY (Test Reference Year) meteorological data from 2005 to 2014, condensation and thermal bridge analysis were conducted through the THERM program. To this end, the ISO 52016 (formerly ISO 13790) standard program Energy# was used to present the exterior wall insulation performance standards to secure the comfort of the apartment house, and to evaluate the energy performance before and after remodeling for each representative household. Result: An appropriate minimum thickness of insulation to prevent condensation and mold was suggested. When remodeling an apartment house, 45-80㎜ of insulation is the most economical level. It is necessary to study the domestic insulation design method suitable for the living environment.
