摘要

About 30% of the global population lives in earth buildings. To meet the needs of modem life, improved technologies have been used in such buildings. But, how well does that work? Unfortunately, such evaluation are lacking. So, this study focused on developing a comprehensive evaluation method. First, 19 improvement schemes were proposed based on field tests of an adobe dwelling in Gansu, China. Then, a modified method to evaluate the improvement technologies was proposed. The comprehensive evaluation addressed four constraints ecology, economy, energy savings, and thermal comfort with six indexes. Furthermore, two real-world problems were solved. One was the subjectivity of index weight, and the other was the target value fluctuating within a certain range. Finally, an analysis and comparison of each scheme between four isolated evaluations and a comprehensive integrated evaluation were carried out. The results indicated that comprehensive evaluation was superior and that the grey interval relational decision algorithm (GIRDA) can effectively evaluate improved technologies. Furthermore, it was recommended that, when capital is limited, insulating roofs with rice husk is the best choice. These results are intended to provide guidance for improving the standard of living in poor rural areas in China.
