The architecture of each place develops according to its climate, culture, materials available locally etc. Generally, our buildings from the past are much more sustainable than even the platinum rated buildings (the so called "green buildings") that are being built today. Our "vernacular architecture" is more suited to the climate, culture and society, while the so-called modern buildings can follow the same style and they look the same whether they are in Brazil, Europe, Egypt or in India. Some of these glass buildings in a hot climate let in all the heat and then we use "green methods" of air-conditioning and still the energy consumed by these buildings are so high which make them unsustainable.
