축소 모형 실험을 통한 흙집의 동계 열환경 및 에너지성능 평가

With the increase in the demand for sustainable and environment-friendly development, the preference for earth construction material increases more and more. Earth construction material is used for the house and it is known to have a low impact on the environment due to its low embedded energy consumed to make an end use product. However, there is only little data on the indoor thermal environment and end use energy performance of the modern earth house constructed with current earth construction material because the modern earth house was introduced into the Korean construction market recently. In this study, indoor thermal environment and heating energy performance of the modern earth house were evaluated through the scaled model test in the winter. The inside and outside air and surface temperatures were measured to evaluate the thermal environment. The electricity consumption for radiant floor heating was measured to evaluate the heating energy performance. In view of heating energy performance, the results show that cases 2, 4 and 5 with earth construction material are a little better than cases 1 and 3 with cement construction material. In view of indoor thermal environment, the results show that there is little difference in the cases without heating.
