A new approach to the cooling of buildings across the developing world that needs nothing but wind and sun to operate has been devised by engineers in India. Writing in the International Journal of Sustainable Design, the team explains the concept of a combined solar chimney and wind tower system that can reduce the temperature of incoming appear by 5 degrees Celsius.
Jyotirmay Mathur of the Mechanical Engineering Department, at the Malaviya National Institute of Technology, in Jaipur, together with architect and urban designer Rajeev Kathpalia of Vastu Shilpa Consultants, in Ahmedabad, point out that the development of energy-efficient, and even passive, cooling systems for buildings is essential in the light of environmental pressures and costs. In the past, they point out, building designers had to rely on natural ways and means for maximising comfort inside buildings.
