Compared to overseas curtain wall products, domestic curtain wall products have a negative thermal performance. To develop curtain wall frame with thermal conductivity 1.0 W/㎡·K or less, it is importance to figure out the thermal performance factors and effects of each part or curtain wall frame. In this work, thermal performance factors such as form and material were classified on 6 parts; aluminium part, gasket, thermal break bar, gasket for setting wimdow, aluminium cover and screw. The thermal performance effect of each part were also calculated according to ISO 12631 and the results were present as a thermal performance improvement rate with in range from the lowest curtain wall thermal transmittance to the highest. The results show that it is thermal break bar which has greatest effect on improving the thermal performance of curtain wall, especially with soft PE foam.

This study reviewed the possibility of setting a remodeling base model through the review of the error between the building energy simulation and the energy consumption of actual building. Through monthly method simulation, final energy was calculated for one public building and one house, and baseload energy was calculated using bill data. By comparing the sum of the simulation results and the baseload energy with the monthly energy consumption, it was confirmed whether the error range suggested by the M&V guidelines was satisfied. This study tried to cost-effectively secure usable data as a remodeling base model. Through the analysis cases in this study, it was confirmed that the base model before remodeling can be estimated only with the monthly method simulation results and monthly bill data.

As the national greenhouse gas emissions are being reduced, energy savings in the building sector among the total greenhouse gas emissions are becoming more important day by day. The government did not have legal regulations on small buildings less than 500m2 by 2030 to reduce building energy use, but most of the nations small building stocks have insufficient research on small buildings due to low interest and understanding of energy performance. In addition, building energy used in small buildings less than 500m2 accounts for 46% of the total use, which has a significant impact on energy consumption, which requires countermeasures. Therfore, In the small building market, a load calculation program is needed that can be used more easily by architects and interior companies. Furthermore, support for input automation is needed, which reduces the time spent by users to input data, making it easier to respond to frequent planning changes during the architectural design phase.

In this study, using the cooling and heating load program using DIN V 18599, the heating and cooling load results are compared by comparing the type that applies the wall with a general thermal transmittance to the type that applies the effective thermal transmittance including the additional heat flow. Through this, the effect of the additional heat flow of the structure on the overall result was identified and the necessity of detailed evaluation of the structure was confirmed. Through this study, it was confirmed that there was a big difference in the overall result even though only the outer wall of the structure was considered as a prior study on the need for a detailed evaluation method of the structure. Through this, unlike the existing method of analyzing building energy through thermal transmittance, it is necessary to analyze building energy through effective thermal transmittance considering the additional heat flux of various structures. is considered to be of great help to
