초록

Current Korean building energy policy and standards provide only the specific insulating performance standards of the building component and it overlooks the prevention of heat loss caused by thermal bridge when evaluating building performance. In this research, details to minimize the heat loss due to thermal bridge was developed to achieve the linear thermal transmittance criterion(Psi<0.01W/mK) of the German Passivhaus Institut(PHI), performed through two-dimensional heat transfer simulation in a steady-state-condition (ISO 10211:2007). Then, the heat loss from the developed passive house details was compared with the exampled details as per the current Korean building code, and their effect on the annual heating energy demand was weighed according to the calculation method in PHPP(the building energy performance evaluation program of the PHI). Lastly, the possibility of condensation and mould was evaluated by using the temperature factor (ISO 10211:2007). As the result, while the overall heat loss through thermal bridges in enhanced passive house details was minimized to $1.1kWh/m^2a$, the gross heat loss due to thermal bridge in exampled details was $35.3kWh/m^2a$, which exceeds alone the annual heating energy demand criterion ($15kWh/m^2a$) for passive house set by PHI. This shows that enhancing the building energy performance to the high-energy-efficient standard will be hindered, if minimizing thermal bridge is left neglected. Therefore, it is necessary to set up specific criteria to minimize the heat loss due to thermal bridge, in order to achieve the Korean building energy-efficiency road map set by the government. In addition, the study for diverse measure to manage the thermal bridge details in design and construction process is needed.
