AIIMS campus in Delhi to become climate-responsive

Ministry of Health has recently taken initiative to make AIIMS campus in Delhi climate-responsive. Renowned solar expert SP Gon Chowdhury will attempt to make the half-century-old All India Institute of Medical Sciences (AIIMS) campus in Delhi energy efficient. Gon Chowdhury will also be advising the ministry to ensure that the new AIIMS units proposed in different states - including West Bengal - become 'green buildings'. The task to make AIIMS in Delhi climate responsive will be a tough one. The buildings of the institute dates back to the 1950s, and therefore large-scale retrofit will be  required. Though installing solar panels on the roof will be easy, conserving water, capturing daylight and managing solid waste effectively will be difficult.

"To reach the ultimate goal of a climate-responsive campus, we have to modernize the buildings so that they are more efficient. There are systems and technologies like solar dome to capture daylight and stream it through highly reflective 2-3 inch tubes. This can be used to light up an entire building during the day without the need to switch on electric lights," Gon Chowdhury explained. He also wish to capture the heat generated by air-conditioners and then use it to generate thermal power.

"Retrofit is happening everywhere including Italy, Latin America, the US, Australia and Germany. While any retrofit is a challenge, the bigger hurdle is to change the mindset so that people recognize the importance of being energy-efficient and carbon neutral," said Gon Chowdhury.
