The shading devices used in the SRCC building.
It's an absolutely gorgeous building which me and Rohan visited back in the summer holidays- so we saw it when classes were off and the Delhi heat was at its worst. The climatic response is very cool (pun not intended): basic orientation and different designs for different facades, colonnades, deep recesses, projections, ventilators, sun shades -the picture above being only one of many types used here.
Any idea who designed this? Preliminary online research just yields this very introductory article on SRCC's architectural style, with no mention of the architect himself.
