Abstract: To address the existing problems on solar building integration,some novel concepts,methods and functions of the comprehensive utilization of BIPV/T are proposed. They can not only improve the comprehensive utility efficiency of solar building integration,reduce cost,but also make solar energy more functional and more efficient all year round. The paper introduces relevant new achievements of University of Science and Technology of China,including principles,functions,and efficiencies of the BIPV/Water system,CdTe（cadmium telluride）PV-ventilation system,composite passive BIPV/T-wall system,BIPV/T-catalytic/sterilization wall system,which expand new ways of research and application of solar building integration. The results provide novel methods to realize large-scale applications of solar buildings and create a healthy and comfortable indoor environment.
