Comparative study on energy consumption of AAC green prefabricated dwellings based on BIM technology

Abstract

Using BIM technology, the parameter modeling of the prefabricated building of new rural residential houses was carried out. Through DeST software algorithm, the difference of key energy consumption index between AAC energy-saving materials and the brick-concrete structure used in traditional rural residential houses was compared. Compared with the traditional brick-concrete buildings, the new rural residential buildings using AAC components have obvious advantages in terms of cooling and heating load index of equipment system and room cooling and heating load. From the aspect of building energy consumption, the data verified the excellent performance of AAC materials in building energy conservation, and the possibility and importance of applying AAC materials in the new rural residential buildings under the background of rural revitalization, which played a positive role in promoting the practice and exploration of new residential green buildings in the process of rural revitalization.
