Beijing Solar Energy will achieve tighter collaboration or joint efforts with building design institutes and solar energy companies along with the comprehensive integration of solar energy buildings. This can not only improve the quality of solar energy buildings but also explore broader spaces and fields for solar energy utilization. One is the New Energy Village of Daxing County in Beijing, which is a collaboration between Tsinghua University, Tianjin University, Beijing Solar Energy Research Institute, and Germany; the other is the Lanzhou Passive Solar Heating and Cooling Technology Demonstration Base.
