In the heart of the Tibetan Plateau, where winter temperatures can be harsh and infrastructure access limited, clean and sustainable heating is not just a convenience—it’s a necessity. In 2023, a groundbreaking solar space heating project was completed in Zhegu Town, Jimei County, Shannan City, bringing warmth to traditional Tibetan homes through innovative technology and thoughtful design.
Project Background
This initiative focused on the retrofit of traditional homes—many of which were poorly insulated and lacked modern heating infrastructure. The goal was to integrate a clean, efficient, and culturally respectful solar heating solution without altering the architectural heritage of the buildings.
The project deployed high-efficiency flat plate solar collectors strategically mounted on the rooftops of renovated homes. These collectors absorb sunlight and transfer thermal energy to a closed-loop water circulation system, which then distributes heat through floor or wall radiators inside the home.
Solar space heating is ideal for high-altitude and rural areas with good solar irradiance. It significantly reduces reliance on coal, wood, or diesel heating—helping communities improve indoor air quality while reducing fuel costs and environmental impact.
✅ Zero emissions during operation
✅ Stable indoor temperature (18–22°C)
✅ Low maintenance with minimal electricity needs
✅ Seamless integration into existing homes
One of the biggest challenges in this solar heating retrofit was the need to work within the traditional Tibetan architectural style. The engineering team developed a compact mounting solution for the flat plate solar collectors that maintained visual harmony with the buildings while maximizing solar gain.
Backup heating was also integrated for cloudy periods, using electric heating elements powered via grid or generator, ensuring consistent warmth throughout the cold season.
Since implementation, the solar space heating system has greatly improved residents' comfort during winter. With no need to burn solid fuels indoors, homes are now cleaner, safer, and more energy-efficient. The community reports higher satisfaction, and local authorities have praised the model as a scalable solution for other villages in the region.
