People of Ladakh are exposed for more than seven months a year to sub-zero temperatures. Using traditional heating (e.g. Bukharis) and conventional heating (coal, kerosene etc.) are expensive and also causes noxious and polluting emissions. The active solar heating technology is a big advantage as the system can be built and installed with locally available materials and resources. The solar air-heating system is enhanced by integrating it to thermal energy storage and insulation of the houses. Solar panels are installed on the rooftop of the house, and the additional layer of insulation is added to conserve heat loss from walls and roof of a heated room. This technology is a huge benefit to high-altitude regions, such as Ladakh – offering sustainable solutions for energy demand in Ladakh and regions with cold climate.
