Building green is definitely important. But it is equally important to know how green a green building is. Take the glitzy, glass-enveloped buildings popping up across the country. It does not matter if you are in the mild but wet and windy climate of Bangalore or in the extreme hot and dry climate of Gurgaon - glass is the in thing.
