Building environment is the only one of core basic courses which shows differences of the major of built environment and energy application engineering with other majors. According to features and characteristics of built environment, while considering real conditions of student numbers, teaching arrangement and objectives among universities, two aspects of teaching practices are presented. The link of building environment and the other courses is analyzed and emphasized. Not only avoiding teaching contents repeated but also adding extended knowledge are suggested. It is an effective way for encouraging students active thinking to arrange field testing and discussing in classrooms. A good teaching effect can be achieved by connecting the text with actual living phenomena and engineering application.
