New Delhi, March 24 -- Ladakh's solar potential provides an opportunity for renewable heating, especially for buildings with spaces that do not have access to the southern sun. An example is the Indo-Tibetan Border Police (ITBP) campus in Leh, Ladakh. The campus utilises radiant heating technology to warm two four-storeyed buildings. The heating technology used is called Concentrated Solar Power. In this system, the sun's radiation is focused onto a silver tray, where curved collectors capture the solar energy and heat a glycol-water fluid to temperatures between 45 C and 50 C. The heated fluid then circulates beneath the building floors through 20 mm pipes, warming the indoor space. A 35-kilolitre storage tank stores the heated fluid and...
