In Korean apartment buildings, internal insulation system is usually applied, so necessarily the layer of insulation is disconnected due to structural component at wall-slab and wall-wall junctions in envelope. Liner thermal transmittance is required for energy performance evaluation including the effect of these thermal bridges. As it is calculated by a person with suitable expertise and experience with 2-D heat transfer simulation, it would be more easy and useful for non-specialists to calculate linear thermal transmittance through regression model. In this study, the regression model for linear thermal transmittance of wall-slab junction with internal insulation is suggested. which showed a good match with that from 2-D heat transfer simulation. |
