Xizang Autonomous Region of China has a high altitude, low air pressure and a cold climate. Conventional energy sources such as coal and natural gas are scarce and extremely costly to transport. For a long time, burning cow dung for heating has been the main way for most local residents to keep warm in winter.

Following more than two decades of technical research by the scientific research team of Xi'an University of Architecture and Technology, a number of clean heating projects based on solar energy have been successively built in Xizang. The long-standing reliance on cow dung for heating in these areas is becoming a thing of the past.

中国西藏自治区海拔高，低压高寒，煤炭、天然气等常规能源匮乏且运输成本极高。长期以来，烧牛粪取暖是当地大部分居民冬季御寒的方式。经过西安建筑科技大学科研团队20余年的技术攻关，一批依托太阳能的清洁供暖工程在西藏陆续建成，这些地方的人们长期以来主要依赖牛粪取暖的日子正成为历史。
